Reliable roof garage is an important condition safety of the building. Roofing in a garage they are basically carried out in the same way as in other buildings, but there are some nuances.
Types of garage roofs
Based on their design features, several types of roofs can be distinguished. Based on the presence of roof slopes, there are:
- pitched;
- flat.
A flat roof requires a continuous elastic covering made of polymer-bitumen materials that are resistant to temperature changes. The supporting parts for such a structure are the walls of the building. Screeds or slabs can be used as a base. In some cases, a hanging garden is made on a flat roof. In this case, the structure will be operational.
A pitched roof is formed by bases, the angle of inclination of which can be from 10 to 60°. The structures focus on the rafter mechanism. For a garage you can build the following types roofs:
- With one ramp. The structure has an emphasis on the walls of the building, and therefore one of the walls must be higher than the others in order to be able to create a slope. The height difference is calculated by the formula: H = tg α x s, where s is the width of the building, tg α is the tangent of the angle of inclination, the value of which can be calculated on a calculator or taken from Bradis tables. The size of the roof slope depends on the climate of the region: the amount of snow and the strength of the constant wind.
A pitched roof is formed by walls of different heights
- With two slopes. This option is most often used when constructing garages, as it allows you to increase the usable area of the building due to the attic space. A roof of this type can be made with or without an overlap, but it must rest on a mauerlat - a horizontal frame made of bars that combines the rafter mechanism into a solid structure.
The gable roof increases the usable space of the garage due to the attic space
- Hip roof. It is used quite rarely for garages, but in some cases it is used to maintain uniform style territory development. In this case, the rafter mechanism will not have a ridge run, since the roof frame is formed by four identical slopes.
The hip roof consists of four identical slopes
- Attic. This type of construction allows you to build over a garage building extra room, which can be used by the owner for his own needs. For example, you can create a workshop, storage room, office or guest room. It differs from the attic space in the height of the ceiling: at least 1.5 m. This roof project is considered expensive, since it requires steam, hydro and thermal insulation. It is also necessary to install non-standard shaped double-glazed windows. The rafter pair will have a sharp bend, which may result in a decrease in the strength of the building.
The minimum ceiling rise in a room under an attic roof is 1.5 m
Materials and tools for manufacturing
Proper construction of a roof with a single slope implies maintaining the slope required for an unhindered descent melt water after rains or snowfalls. The height of the supporting parts should be different. The slope should be selected taking into account the following factors:
- Climate of the region in which the events are held construction works. Flat roofs with a slope of 5–7° are not advisable in regions with a lot of snow. However, they are suitable for places where there is strong wind. Roofs with a slope of 20–25° should not be constructed over detached garages in regions with moderate winds. Such structures can only be erected over attached buildings.
- Type of coating material:
- when making roofs with a slope of 15° or less, it is necessary to use materials in rolls - polymer, polymer-bitumen or bitumen;
- if the slope is up to 10°, then the roof should be installed in 2 layers;
- at an angle of inclination of 17–20°, metal sheets fastened with a seam, flat or wavy slate are used;
- for roofs with a slope of 25° or more, it is better to choose profiled sheets or metal tiles.
- Site design. Architectural features require the use of roofing of the same color and shape throughout the entire territory.
When calculating the area of the slope, it is necessary to take into account the installation of overhangs that protect the structure from rain.
Overhangs are extensions of the roof structure that protect the building from rain and snow.
It is important to consider the following nuances:
- There should be overhangs of 55–60 cm above the log house.
- The overhang over the iron-clad frame structure should be at least 15–20 cm.
- The overhang over a building made of concrete or brick should be 35–40 cm.
In some cases, the size of the overhangs is made larger to form a canopy from the entrance or along the wall. The canopy will need to be supported on support pillars, made on a separate or common basis with the garage.
Garage roof covering material
The roof of a garage can be covered with different materials. You need to choose based on operating conditions and financial capabilities. For example, a building with a tile roof will cost much more than a building covered with slate. At the same time, laying metal tiles takes a lot of time. The most commonly used materials are:
- Ruberoid. This is a material based on thick or lightweight cardboard impregnated with bitumen. It is covered with refractory bitumen, after which it is added minerals. Tensile load - 26–28 kg. One roll is enough to cover approximately 10 m2 of roof. Roofing material can withstand heating up to 80° for two hours. The material can be used with a slope slope of at least 5°. The rolled sheets are joined with an adhesive mixture or mastic in several layers or fused using a gas torch. Ruberoid is recommended to be used if a garage with a roof is being made complex shape. Main advantages of the material:
- Bituminous shingles. This is an artificial soft material for roofing, which is based on fiberglass impregnated with rubber bitumen with a powder of basalt or slate. Service period - up to 50 years. The decorative effect of the coating is achieved through a wide range of colors and cutting shapes. Bituminous shingles have all the advantages of roofing felt, but have a more aesthetic appearance. Additional benefit is the ability to replace individual fragments when performing repairs. The material can be installed on a roof with a minimum slope of 2°.
A roof made of bitumen shingles has a much more aesthetic appearance compared to roofing felt.
- Ondulin. This is a molded mass based on cellulose, bitumen, various pigments and fillers. After drying, sheets with waves become resistant to chemical attack. The advantages include low weight and low cost. The period of possible operation is up to 15 years. On sale can be found in the material different colors. To fix the sheets, special fasteners should be used.
Ondulin is well suited for garage roofs because it is a light and beautiful material
- Slate. It consists of asbestos cement sheets with a surface in the form of waves. Despite not the most aesthetic appearance and hygroscopicity, it has quite a lot of advantages:
- Iron sheets. The material has polymer coating and is strong and durable. The sheets are folded together into a lock, which requires experience in carrying out this work and special tools. The permissible slope is 19–30°. It is advisable to apply an additional protective coating to a metal roof, which can be done using acrylic paint.
- Profiled sheeting. These are wave-shaped metal sheets that are laid with an overlap in one wave on each side and are attached to the sheathing with roofing screws, which significantly simplifies the installation process. The recommended tilt angle is from 8°.
You can cover your garage roof with a profiled sheet in just one day.
- Metal tiles. Is one of the most popular roofing materials. The properties of metal tiles are similar to corrugated sheets, but they look much more attractive. The coating consists of profiled iron sheets about 0.5 mm thick with a smooth or rough surface, protected by a layer of polymer coating. Average service life is 30 years. The minimum slope is 14°.
From a distance the coating resembles natural tiles, but costs much less
Garage roof tool
In order for the work to be carried out efficiently, you need to prepare the following tools:
- hammer;
- a wooden mallet;
- jack for lifting material onto the roof;
- roulette;
- level for taking measurements;
- spatula if you plan to plaster and paint the garage;
- metal scissors if you plan to use corrugated sheets;
- saw;
- axe.
Some metal roofing materials will require hole preparation. In this case, you should add a countersink and a countersink to the list.
DIY garage roof installation
The roof for a garage building consists of the following elements:
- Rafter mechanism. It is used as a base on which all parts are fixed. The structure will take on the general loads of the roof.
The rafter frame sets the shape of the roof and is its load-bearing part.
- Lathing. Serves as a support for fastening roofing.
The sheathing pitch depends on the roofing material used
- Materials for hydro-, steam- and thermal insulation. Required to retain heat and protect the building from moisture.
In order for the roof to retain heat and protect the garage from moisture, you need to lay insulating materials in a certain sequence
- Finish coating.
Laying the finishing coating is the final stage of roof construction
- Additional parts to strengthen the rafter mechanism.
If you plan to build a garage with a pitched roof, then you need to place a mauerlat or logs on the upper end parts. The elements will be used as support for the rafter mechanism. They are fixed to the walls using wire through anchor bolts. The fasteners must be driven into the wall or embedded in the masonry.
The main parts of the rafter mechanism of a gable roof are the rafter legs. They can be:
- suspended (supported by the outer parts);
- layered (have intermediate parts for support).
If the span formed by the supporting walls is less than 5 m long, then only horizontal elements can be installed on the rafter frame. They are called crossbars. In the places where the mauerlat and rafter legs are attached, you need to prepare holes for fastening. The supports are installed in these holes and securely fixed with nails or anchor bolts.
Mauerlat installation
Laying the roof for the garage should begin with the installation of the Mauerlat. For this, a 15x10 cm beam is used. If the walls of the garage are made of timber, then the upper crown can be used as a Mauerlat.
- For walls made of brick or concrete blocks, a reinforcing belt is made. Steel pins are mounted into it, onto which the Mauerlat will then be put on. The design of the armored belt is required not only to distribute the loads from the roof, but also to horizontally align the end surfaces of the walls. Without this element, the slope may be different in different parts of the roof.
Before pouring concrete, metal threaded rods are welded to the reinforcement frame so that their protruding part is several centimeters longer than the mauerlat beam
- Concrete is poured into the formwork, its surface is finally leveled, and then the structure is covered with a layer of roofing material and left until completely dry (at least 7 days).
After leveling the concrete layer, the studs should extend out of it to a height exceeding the thickness of the Mauerlat by 3–5 cm
- The mauerlat beams are mounted. At the locations of the studs, holes of the appropriate diameter are drilled, and the beams are put on the studs. The nuts are screwed on top.
After the Mauerlat beam is laid on the armored belt, it is secured using nuts screwed onto the ends of the studs
- The rafters are fixed to the mauerlat. The simplest method is two nails with a length of 150 mm, located crosswise, or iron staples. For more high-quality fastening metal plates can be used.
Using metal plates you can make sliding mount, which will allow elements to move within small limits during frame shrinkage and seasonal deformations of the building
Marking rafters and making sheathing
At this stage you will need to mark the rafters:
Installation of rafters for pitched roof is not difficult. When installing a rafter mechanism, you should be guided by the following principles:
As the base of the garage roof, a lathing made of slats or iron purlins should be used under the covering material. The sheathing is selected as follows:
The sheathing must be done from bottom to top.
Each batten should be attached to one nail to the rafter leg.
Insulation and waterproofing of garage roof
External insulation of a garage roof should be done in the following sequence:
Internal roof insulation is performed as follows:
- First of all, a waterproofing layer is performed. The joints are sealed with tape.
It is better to lay the waterproofing film with a slight sag to avoid excessive stress due to temperature deformations
- If you plan to use polystyrene foam, then a sheathing must be made under it. Next, the sheets are attached using self-tapping screws. During the process, you need to glue the joints with an adhesive mixture.
- If mineral wool is used, it is placed in the gaps between the rafters.
Mineral wool slabs should fit into the gaps between the joists and stay there without additional fastening
- The insulation material is covered with a vapor barrier film. The joints are taped with construction tape.
The vapor barrier film protects the insulation from warm, moist air escaping from the lower rooms
Care should be taken to insulation material did not come into contact with the waterproofing film. There should be a gap between them. To do this, a counter lath made of 30x40 or 50x50 mm bars is stuffed on top of the film. If a superdiffusion membrane is used for waterproofing, a ventilation gap is not required.
Insulation of the roof inside can be done using penoizol.
Penoizol is applied to the roof by spraying
The foam material should be applied by spraying. It will penetrate into all gaps, expand as it dries and be distributed throughout the entire base. As a result, there will be no cracks into which moisture or cold could penetrate. Penoizol is one of the best materials for insulation. It eliminates the appearance of fungus and mold. The only drawback is the high cost. However, it should be remembered that the period of possible use of the material is 70 years.
Bitumen mastic is most often used as a material for waterproofing pitched roofs. The coating distributed over the roof surface can form a base with excellent waterproofing parameters. It is also possible to use anti-condensation film, which is made on the basis of viscose. This option is most often suitable for roofs that are covered with profiled sheets.
Waterproofing is carried out after the rafter system and sheathing have been completed, and the insulation has been laid:
If the roof is not ventilated, then the waterproofing material should not be an ordinary film, but one with condensation protection. It is also possible to use a modern vapor-permeable membrane, which will remove excess water vapor to the outside. The waterproofing process can be facilitated by using a self-fusing roof. However, it is important to ensure that the coating material does not overheat.

Laying roofing
One of the popular options is the installation of roofing material made of roofing material.
Step-by-step guide to laying roofing felt
Roofing felt is mounted on a continuous sheathing. The material can perform two functions at once:
- protect interior spaces from precipitation;
- create a continuous budget coverage.
Ruberoid - soft roll material for roofing, so it is easy to install. To reliably protect the roof, roofing felt must be installed in 2-3 layers. The first layer is used as a lining, and subsequent layers are used as the main coating.
In addition to roofing felt, other roll-type materials can be used. They are laid out on mastic or fused using a gas burner. The second method requires increased attention, because it is a fire hazard. Such work should be performed by a person with experience.

Sequence of installation of corrugated roofing sheets
Corrugated sheeting has little weight, so it is possible to save on the manufacture of the rafter mechanism and sheathing. Rafter legs can be made from bars 100x30, 50x30 or 50x50 mm. The choice must be made based on the load on the rafter mechanism. To create a high-quality roof, it needs to be insulated and waterproofing material laid. Sequencing:
- Waterproofing is laid on the surface of the frame. In this case, it is allowed to use polyethylene film with a thickness of 200 microns. The film is fixed to the sheathing using thin strips with a cross-section of 20x20 mm. The distance between the slats should be such that the profiled sheet can fit tightly on the parts.
For laying profiled sheets with a thickness of 0.4–0.5 mm, a sheathing pitch of 50 cm is sufficient
- Placed on top of the waterproofing material metal roofing. The corrugated sheets are secured to the sheathing using special self-tapping screws with rubber linings. For convenience, you can pre-drill small holes in the base. Self-tapping screws must be screwed in without tension so that the material can contract and expand with temperature changes.
Sheets of corrugated sheets are fastened with roofing screws into the recess of the wave
- The roof is insulated from the inside of the garage. The process of insulation under corrugated sheeting is completely similar to that described above.
- WITH inside roofing is mounted vapor barrier film and finishing coating of the walls and ceiling of the attic.

Features of laying seam and slate roofing
Laying a seam roof made of galvanized metal is possible only with certain skills and special devices. It is not recommended to do this yourself.
A slate roof can last more than 40 years. The material is laid in the same way as corrugated sheeting, but slate has a lot of weight. Accordingly, he needs a strong and reliable rafter mechanism. Rafters must be made of wooden blocks with a cross-section of at least 100x80 mm.

Garage roof operation and maintenance
Soft surfaces are quite durable, but regular inspection of the substrate is recommended. Signs that indicate the need for repairs:
- Various mechanical damage: through abrasion, deep crack, burst hole.
- The appearance of depressions in which water or dirt can stagnate.
- Change in the appearance of the coating: the appearance of moss, mold or mildew.
- The occurrence of emergency delaminations at joints.
If these signs are present, it is recommended to have your roof repaired immediately. Experienced specialists recommend that garage owners carry out regular maintenance of the structure at least once every 3 years. In this case, it will only be enough to eliminate minor flaws. If the roof remains in a neglected state for a long time, a complete replacement of the covering may be required.
Garage roof repair
The repair method depends on the type of roof and the degree of wear of the building. In private buildings, where the garage is located separately from the building, budget roofing materials are used with long period services. Garages in cooperatives cannot be covered with profiled sheets or flexible tiles, so soft bitumen-based materials are used. There are 3 options for repairing a garage roof:
- Using heated bitumen.
- Application soft material for the roof.
- Use of profiled sheets or tiles.
Before you begin repair work, you will need to remove debris from the roof and clean the areas that will need to be repaired. If the previously installed coating material can be used, then you will need to cut out the recesses in places with defects with an ax. If the roof was covered with roofing felt, then the structure must be inspected for cracks or swelling. Such defects must be corrected before repair work.
When the preparatory work has been completed, you can begin repair work:
Repairing a roof using roofing felt is quite simple. You will need to cut out several pieces of material and then use them to close the recesses. Each segment must correspond to the size of the recess. Sequencing:

It is entirely possible to build a durable garage roof yourself, but it is important to follow the instructions and choose quality and reliable materials at all stages of work.
It’s not difficult to build a simple garage roof with your own hands. But to do this correctly, you need to prepare well in advance. After all, you will have to take into account a number of important points - when and why to do insulation, whether a vapor barrier is needed and what to do to eliminate possible leaks. In addition, depending on the condition and location of the building, the construction strategy will differ significantly.
What should you think about before installing a roof?
The first thing you need to decide is the purpose of the garage. If it is unheated and will be used only for storing the car, the roof can be anything as long as it does not leak. But if the garage is planned to be warm or will be warmed up from time to time, used as a workshop or a local “café for car enthusiasts”, the roof must be insulated!
An uninsulated metal roof will condense, providing an unforgettable indoor rain experience in winter. A wooden or concrete one will heat up, melting the snow outside. And this is fraught with ice stalactites and stalagmites, which will have to be knocked down regularly. And it’s good if the roof slope is on the back wall, and not in front of the gate.
If you have a hood, it is also better to insulate it and raise it above the roof - so as not to drown the same snow.
Don't forget about minimum inclination with mandatory drainage for flat roofs. Otherwise, rain and snow may linger in uneven areas, which cannot be avoided during self-construction. And this is fraught with possible leaks or destruction of the roof in a few years.
And, of course, it is better to correctly assess your strengths in advance and draw up an estimate. Because sometimes cheap option is not suitable due to its complexity when constructing it with your own hands, and expensive material can be replaced with something cheaper. After all, a garage does not require a special margin of safety and high environmental friendliness of the roof.
Do-it-yourself concrete roof for a garage
The simplest option is to lay concrete slabs. But you can’t do it without a crane. If its use is impossible for some reason, you will have to make a concrete screed yourself.
For this you will need:
Among the tools you should think about in advance:
It greatly simplifies working with concrete, especially if your hand is not yet full, as is clearly shown in the video:
Pouring a concrete garage roof
So, all the materials are stored, the tools are ready and you can start building the roof. For this:
- Floor beams - pipes, channels or I-beams - are laid on the walls. In the first two options, the roof will be poured on top. If the beams are made of an I-beam, boards or metal sheets are laid on its lower edge, onto which concrete will be poured. When installing an insulated roof, foam plastic can be laid under the screed.
- The reinforcing mesh is knitted. It is important not to forget that the rods should not touch the formwork, because then rust may begin to appear at the ends. But reinforcement can be welded to the floor beams. The advantage of I-beams is the ability to fill “layer by layer” - one row at a time. This is especially important when pouring it yourself, since it’s definitely not possible to do the entire roof at once.
- The formwork is fixed. To make it easier to tear it off from the concrete, the inner walls must be coated with used machine oil or any other cheap oil. The boards should fit as tightly as possible! Concrete “milk” coming through the cracks significantly worsens the quality of the monolithic floor.
- The reinforced mesh is poured with concrete mixture, be sure to be bayoneted and smoothed according to the rule. If it is possible to order a ready-made concrete mixture to pour the entire roof at once, you must have at least two assistants to level the mixture with shovels. It’s better to use a deep vibrator when pouring like this, which will help quickly remove air from the mixture.
- The concrete screed is covered with plastic film and must be watered regularly. Without watering, concrete will not gain the necessary strength.
- After the screed has set, all cracks must be closed. This is done by ironing - it crumbles onto the surface thin layer cement and rubbed in with a regular paint brush. The procedure continues until all cracks are sealed.
- All joints in the screed are coated with mastic reinforced with serpyanka. The same applies to the exit point. ventilation pipe, and the upper ribs of the channels.
- To ensure the required level of water resistance, a built-up waterproofing layer is laid on top of the concrete. Be sure to cover the ends of the concrete floor! To do this, the concrete is coated with a primer, and the waterproofing itself is spread in two layers - for reliability. To ensure that the waterproofing does not lag behind, the edges can be pressed with aluminum strips. The dowels are filled with bitumen, and the planks themselves are coated with the same sickle-reinforced mastic.
Concrete roof restoration
But what to do if you inherited a garage? And along with the building, the new owner also received associated problems in the form of a leaking roof and crumbling concrete floor? In this case, restoring the roof will not be much simpler than pouring a new one:
You can also restore a leaking roof by making a ceiling of corrugated board or slate on top. To do this, without removing the old roof covering, logs are laid and secured with anchors. Joints around the perimeter are sealed polyurethane foam– for sealing and to prevent the entire ceiling from being lifted by the wind.
The sheathing is fixed to the joists. If the metal is thin, then it is advisable to do the lathing frequently. The edges are protected with metal corners that prevent moisture from leaking from below. After the roofing has been laid, a wind strip must be installed.
It is also called end - it protects the ends of the roof from water entering from above.
A very accessible description of the restoration of a garage roof using corrugated sheets is shown in the video:
DIY wooden garage roof
If concrete work seems complex and time-consuming, the garage roof can be made of wood. More precisely, the rafter system will be wooden, but the roofing itself can be anything from metal to ceramic.
Shed garage roof
This is the simplest option that does not require serious calculations and special construction skills. The only thing you have to take into account with a detached garage is the prevailing wind direction. The lower edge of a pitched roof should be on the windward side - that is, on the side from which the wind most often blows. Otherwise, strong gusts can simply tear off the roof.
Such a roof is extremely simple to erect:
- A support board is attached to the wall of the house above the level of the garage wall. With a purlin width of up to 4.5 meters, the rafters will only be placed on support board and the wall of the garage. If the width of the garage is planned to be up to 6 m, you will also have to attach a support at the same level with the wall of the garage, on which the rafter leg will rest, providing support for the long rafter.
- If the walls of the garage are brick or concrete, a mauerlat made of 15x10 cm or 15x15 cm timber is attached along the upper edge. It provides the necessary strength to the entire roofing structure, redistributing the load on the wall. To prevent the wood from rotting, the timber must be treated with an antiseptic and several layers of waterproofing placed under it.
- The rafters are attached to the mauerlat either with an outlet beyond the wall or without an outlet. You can calculate the length of the rafters and the angle of inclination using the table.
- The waterproofing is laid directly on the rafters. It is fixed on top with counter-lattice bars, on which the lathing is then placed. The waterproofing is laid with an overlap; the overlaps are taped with butyl rubber tape. You can also place tape under the counter-lattice as a seal to seal the puncture sites.
- Depending on the chosen roofing covering and the angle of inclination, the sheathing can be either continuous or sparse. This should be taken into account, otherwise the roof may simply fail under critical loads.
Gable roof garage
This option for a DIY device is much more complicated and requires serious calculations. Yes, and more material will also be required. For example, insufficient thickness of rafters can lead to sagging of the roof, resulting in stagnation of snow and bursting rafters due to weight. And even with required thickness a large number of knots in timber can lead to the same results. But such a garage looks presentable, and the space under the roof can be used for storing household equipment.
The principle of a gable roof:
- It is important to decide on the height of the roof - if the roof is too high, the wind will try to topple it, and if it is too low, it can lift it up.
- The rafter system is assembled - triangles consisting of rafter legs and tie rods. For garages more than 6 meters wide, more a complex system using crossbars or headstocks.
- You can either collect individual elements on the ground, lifting them as needed, or immediately on the walls. The first option is more suitable for garages, since the ceiling does not spread and in this case it is extremely inconvenient to walk along the edges of the walls.
- First, the outer rafters are installed at the ends of the garage. A cord is stretched between them at the highest point, which determines the level of the roof. After this, you can attach all the other rafter legs. They are fixed with temporary jibs.
- The ridge girder is attached last. To prevent the rafters from moving, they are secured using the cutting method. Also to simplify the work ridge beam can be fixed with building corners without cutting out corners.
- The waterproofing is rolled out and fixed with a batten along the rafters. If you use a waterproofing membrane, it can act as a temporary roof for two to three months, depending on the manufacturer. You need to pay attention to ultraviolet resistance, otherwise the waterproofing can quickly become unusable, simply starting to crumble.
- The sheathing is being filled. The frequency depends on the roof covering. It is better to do it more often than to repair the roof urgently if the roof cannot withstand the pressure of snow.
Regardless of the chosen roofing covering, special attention should be paid to the ridge unit. A poorly made ridge is a guarantee of a leaking roof and the formation of condensation, since the ridge serves as ventilation for the roofing pie.
For example, for a metal tile roof, the distance between the sheathing in the ridge assembly should be no less than 3 cm and no more than 5 cm. And the waterproofing should be located on the roof slopes at a distance of 20 cm. The ridge itself is laid on a breathable insulation and fastened with self-tapping screws.
For ventilated roof ridge with soft roof You can use either ready-made solutions in the form of a ridge aerator or make the design yourself. The first method is much simpler, but significantly increases the cost of construction.
The second option will require a little more effort, but will save you money. The construction of a ventilated ridge with your own hands begins with cutting a ventilation gap in the continuous sheathing. Next, 5x5 cm bars are attached above the ventilated hole, on which the OSB sheets are laid. To protect the roofing pie from dust and insects, you can also secure metal mesh, which is wrapped on bars.
conclusions
To summarize, we can draw the following conclusions when building a garage roof with your own hands:
- it is better to restore a concrete garage roof using corrugated sheeting - it is easier and cheaper;
- concrete work must be carried out with an assistant, otherwise the roof will have to be poured in parts and the joints sealed;
- roof insulation is a must for protection against condensation;
- for a concrete roof, built-up waterproofing is used according to concrete floor, for wooden – windproof membrane, preventing the formation of condensation;
- the thickness of the rafters should be sufficient to withstand the maximum snow load; if the roof slope is small, it is better to do it with a margin of safety;
- if you choose corrugated sheeting as the cheapest option, you should pay close attention to the quality decorative spraying– from unscrupulous manufacturers it can peel off within a year;
A flat garage roof is most often used when there is no large area designs. And when the garage roof sagged, this clearly determines that the plane does not correspond to the load that occurs during precipitation.
Therefore, when making a flat roof, you must first of all choose the right covering material. Here you need to proceed from your capabilities; if you cover it with concrete, it will be a heavy structure and you will need a garage roof screed.
Not many people will find this option suitable; today we will present you with options for making a flat garage roof.
Choosing material
So, there are many options for covering a flat garage roof. Here you need to first think about the load on the plane. After all, the material used will depend on this.
Attention: The load will not just be from precipitation, this will only increase it. Look at the walls and see how much weight they can withstand. Also consider that the garage roof screed will require constant repairs, so how long will it suit you.
You should never immediately give preference to a material; you should look at photos and videos on the rules and features of its use. And only after that make the final decision.
Roofing corrugated sheets
Speaking in general about profiled flooring, it is important to note that this material today enjoys particular success and popularity; it is usually made of steel, which means it is not difficult to understand that it is truly reliable and durable.
- The metal that is usually taken for its manufacture is thicker, compared with metal tiles; the sheets, in turn, can have both a rectangular and wavy profile.
- On top of the sheets you can find special additional polymer protection, and the profile, in turn, can have the appearance of a trapezoid, wave, or rectangle.
| Installation | When starting to think about it, remember that the slope should not be less than ten degrees; moreover, during installation you need to make an overlap of about twenty centimeters; if the roof has a slight slope, it must be filled with sealant. As soon as you start fixing, this should only be done self-tapping screws, as they are ideal for performing such work. |
| Durability | You should know that manufacturers of such material claim that it can last more than 50 years, and it is not that expensive, which means that if you want to purchase it, then in any case, do the right thing. |
| Advantages |
|
| Flaws | But unfortunately, corrugated sheeting also has disadvantages, for example, this type of roofing is considered “noisy”; moreover, sound insulation must be done, so take this into account in any case. |
Ondulin is environmentally friendly and waterproof
This coating is distinguished, first of all, by its naturalness and low cost, which means you can always buy it to enjoy it properly. It is also commonly called Euroslate, Aqualine.
You must understand that this material is truly unique, which means it will delight you for a long time.
| Installation | You can always install such a coating yourself; to do this, you just need to approach this issue properly, and everything will work out. |

Slate
Of course, everyone knows that slate is one of the common, traditional and popular roofing materials, which continues to enjoy particular success and popularity.
- It is necessary to install slate when the roof slope is from 12 to 60 degrees; it is also important to note that during installation it is necessary to overlap the sheets in one or two waves, so take this into account.
- Speaking of the service life of this roofing material, it can be up to 40 years, so, in any case, you will definitely be able to appreciate it properly.
- The price of the material is not high and everyone can afford it.
- It is possible to install it yourself and this also attracts the consumer.
- When using this material, you must immediately think about how to raise the roof of the garage, because there must be a slope so that water does not leak.
A garage is a room, of course, not intended for housing, but it cannot perform all its functions if the roof constantly leaks. Car owners especially often encounter this phenomenon in the spring, when the snow accumulated on the roof begins to melt. But a well-made roof will not leak or cause problems, and your car home will always be dry and cozy. What is the best way to cover the garage roof to avoid all the troubles?
The purpose of any garage is to protect against external influences motor vehicle. Rain, snow, and wind can quickly ruin the appearance of a car, and for a motorcycle standing on the street, such effects are simply disastrous. Due to excess moisture, corrosion processes on metal products begin to pass quite quickly, destroying the metal. That is why the garage must be of high quality and have no leaks.
The roof on the garage can be single-pitch or gable. These are the most common options. In the first case, it is easiest to make a roof - it consists of one slope, resting on the walls of the building with different heights. The angle of inclination can be different (up to 60 degrees) - usually this indicator depends on the climate in the region, the wind rose, and the selected roofing covering.
On a note! A roof with one slope is usually constructed if there is no need to create an attic.
The roofing material is laid on wooden rafters. The height of the difference is calculated using the formula H = D x tan a, where D is the width of the garage. The last indicator is selected according to the Bradis table. Wood for rafters must be treated with antiseptic compounds that will protect the material from exposure biological organisms, and it is also recommended to cover it with compounds that reduce the likelihood of fire (fire retardants). The category of shed roof also includes roofing, which is often found on garages built of concrete.
A gable roof is built if the garage is planned to be equipped with an attic. Typically, such a roof has the shape of a triangle. The frame consists of rafter legs connected at a certain angle, supported by the walls and at the top point of their connection. The height of the roof ridge H and the length of the rafters C can be determined using the formulas N = 0.5 x N (Z:2) And C = 0.5 x N/sin (Z:2), where Z is the slope value. For an equilateral roof, the appropriate option is to use the Pythagorean theorem.
Less often, but still, a multi-slope roof is installed. However, it is already much more difficult to implement, so rarely does anyone undertake to build it with their own hands.
Advice! To create a roof on a garage with your own hands, beginners are advised to opt for a simple pitched roof.

Comparison of materials
You can use any roofing materials for the garage roof. Of course, most owners want to save on construction by choosing a material that is suitable in both quality and cost. Let's look at the main types of coatings used for roofing.
Ceramic tiles
This is one of the most beautiful and popular types of roofing material. It is made of clay and therefore has such advantages as resistance to rust, exposure to sunlight, low temperatures and attack by microorganisms. The service life of the coating is long and amounts to about 100 years. Disadvantages include the significant weight of the material, difficulty in transportation due to fragility, and fairly high cost.
Installation of such a roof is easy, but if the roof slope angle is more than 12 degrees, you should not use tiles. It is also not suitable for finishing a concrete garage.

Ondulin
This is peculiar soft version slate, otherwise called euroslate. It has several color variations, which allows you to choose it to suit any building style. The service life of the coating is 20 years (warranty period), the material protects the roof well from leaks, is not dangerous from an environmental point of view, is easy to install and is lightweight. The advantages include its low price. The disadvantages include the flammability of the coating, but it will never catch fire on its own. It also fades quickly in the sun and loses its color brightness.
Prices for various types of ondulin
One of the oldest roofing options. It is a corrugated sheet made from an asbestos-cement mixture. The material is durable, easy to repair, does not rust, is cheap, and does not burn. However, it is quite fragile, and if the roof is not properly sealed, leaks can form.
On a note! Slate is one of the cheapest coating options, which is why it is often used to finish the roof of a budget garage.

Metal corrugated sheeting
A roofing option that replaced slate. It is made of galvanized thin steel sheet, has waves or trapezoidal corrugations, due to which it acquires additional strength.
The material is easy to install, has a lot of color variations, and lasts a long time if installed correctly. Due to the polymer protective coating, it is not afraid of rust and does not fade. Main disadvantage material is that if the polymer layer is damaged, the sheet will quickly rust. Moreover, the coating can be damaged just by walking on it in rough shoes. It costs more than regular slate.
An option that is quite often used for finishing pitched roofs and flat roofs. It is a rolled material consisting of thick cardboard impregnated with bitumen and covered with a protective coating. It is very cheap, durable, well insulates the roof from water, and easy to use. However, the material easily catches fire, breaks, and looks, to put it mildly, ugly. Can be used as a waterproofing layer in roof construction.
Polycarbonate
Yes, you can also use this material to make a garage roof or create a small carport. Polycarbonate can be structured or monolithic. The latter resembles glass and is completely transparent. Suitable for creating flat version roofs.
The first version of polycarbonate is known as cellular or cellular. Very light, quite durable and flexible.
Roofing process
Decorating a garage roof can consist of several stages, depending on what kind of roof is needed. For example, it can be built from scratch and for this you will have to build a rafter system, lay waterproofing, and install a covering. If you don’t need to make an insulating layer, the work will be significantly simplified. Also, the roof may already be ready (for example, concrete), but needs additional finishing.
Important! When choosing a material, it is worth considering the angle of inclination of the roof. For roofing felt best option– an angle of up to 5 degrees, for slate – no more than 25-35, corrugated sheeting is laid on a roof with a slope of up to 8 degrees, and metal tiles can be used on a slope of up to 30 degrees.
All work must be carried out only under the condition sunny weather. It is best to check the forecast for at least a week and choose warm days.
Concrete roof finishing
Even if the garage already has a concrete roof, it must undergo special preparation before the new roofing material is installed. In general, the process begins from this stage and ends with laying a new coating.
Preparation
Step 1. Old covering with concrete slab, if any, will have to be removed completely. This is done using improvised means - for example, a shovel, chisel, etc.
Step 2. Concrete surface is inspected - its condition must be good before further finishing. It is tapped with a hammer - everything that peels off during the process must be removed.
Step 3. All small cracks are sealed with cement laitance (or liquid glass), which is applied with a regular wide brush. Wide cracks can be sealed with polyurethane foam, the excess of which is then cut off with a sharp knife.
Step 4. The uneven base is leveled with cement mortar. It is applied to the surface and leveled using a rule. Next, the cement layer is dried.
Step 5. After drying, the cemented surface is treated with deeply penetrating primer. It is applied with a roller or sprayer in an even layer.
Step 6. When the primer layer dries, the surface is covered with bitumen mastic.
Roofing work on a concrete roof
Step 1. Work on laying roofing felt on the roof begins with lifting rolls of material onto the roof surface. Next, one of the rolls is placed in the corner of the roof and the bitumen mastic applied to the base is heated using a gas burner.
Step 2. Roll of roofing felt without sprinkling using metal hook As the mastic heats up, it carefully unfolds. The burner flame is also directed to the lower part of the rolled material. In this way, the entire roof is covered, individual strips of material are laid overlapping each other.
Step 3. The top layer of material is laid, which already has powder on the surface. To begin with, the required dimensions of the segments are measured. For ease of use, they are rolled into rolls.
Step 4. The top layer of material should be laid on top of the bottom one so that the seams overlap each other, that is, offset. Laying begins from the bottom point of the roof slope.
Step 5. And it's in motion again gas-burner. The previously laid lower layer of material is heated.
Step 6. After the bottom layer is well heated, heating and rolling out of the roll with sprinkles begins. Rolling is also done using a hook.
The same metal hook is used
Step 7 The material laid in this way is sprayed with water to speed up the cooling process. Also, a layer of water will prevent crumbs on the coating surface from sticking to your hands and tools.
Step 8 The material is pressed to the roof surface using patting movements using a wooden board wrapped in fabric.
Step 9 The entire roof is closed in the same way. The individual strips of coating are laid overlapping.
Step 10 The sides of the roof are also covered with roofing felt.

The process of finishing a garage roof with corrugated sheets
Quite often, corrugated sheeting is used as a roofing covering when constructing a garage. This one is durable and durable material will serve faithfully if installed correctly.
Preparation
Step 1. The roof is being prepared - if necessary, a waterproofing layer is laid. Next, the installation of supports for the material begins - 50x50 mm bars are laid on the base, and 40x15 mm boards are placed across them.
Step 2. The bars are leveled strictly, and the crossbar boards are also leveled.
Step 3. The longitudinal bars are attached to the base of the roof using frame bolts.
Step 4. The transverse boards are fixed with self-tapping screws to the bars - two pieces at the edges, and one at a time in the middle of the boards.
Step 5. Planks are nailed along the perimeter of a kind of sheathing. Their upper part should be flush with the crossbar boards. You can start laying corrugated board.
Installation of corrugated sheets
Step 1. Sheets of corrugated sheets are lifted onto the roof, laid on the sheathing and leveled. Separate sheets are laid overlapping in 2 waves. To install the roof, it is better to use sheets of such a size that you can cover the roof slope from edge to edge at once.
Step 2. Where the garage pipe exits, it is necessary to trim the material so that a hole is formed for the chimney. The easiest way is to cut a hole in the whole sheet, and then put the sheet on the pipe.
Step 3. The corrugated sheets will be screwed on with self-tapping screws. For convenience, you can apply markings along a string stretched evenly from one edge of the roof to the other. The markings are applied with a marker. The markings should be located directly along the crossbar boards.
Step 4. Special roofing screws with a rubber washer-gasket are screwed in. Along the perimeter of the sheets, their pitch is 40-50 cm, and along the rest of the sheet, according to the markings, they are screwed through one corrugation.
Step 5. Side part the roof can be finished with roofing felt reinforced on bitumen mastic, or covered with metal shields of the required height.
Step 6. The panels are fixed using roofing screws, and the joints between them and the roof are covered with bitumen mastic.
Step 7 Fabric strips are glued onto the first bitumen layer, which are then coated with bitumen again.
Step 8 The joint between the pipe and the corrugated sheet is sealed with waterproofing material or sealant.

What material should I use for the garage roof? Here the owner himself will have to decide in accordance with his wishes and budget. It is also important to consider the features of each coating. But of the two main materials listed above, it is better to use corrugated sheeting - it will be more reliable and durable for the roof than roofing felt.
Car enthusiasts with extensive experience know very well that a perfectly made roof for a garage is very important, since it is not only the final stage of the entire construction, but also serves as protection from various atmospheric precipitations. Installing a roof is a complex process, so you must first become familiar with what kind of roofs are made on garages and choose the right roofing covering.
What types of garage roofs are there?
The roof for a garage can be varied, so you must initially decide on its design. In many cases, it is possible to replace one type of roof with another, but this requires additional expenses and anxiety. That’s why it’s better to do it at the initial stage of roof construction right choice.
Before choosing one of the types of roof frames, you should decide on its load-bearing characteristics, the size and shape of the box, and then consider one of the presented roof design options.
Features of a pitched roof device
A pitched roof is the simplest type of structure, which is in great demand today, since it has no analogues of similar cost. To equip such a roof, you do not need to use special building materials, special equipment or have deep knowledge in the field of design.
A shed roof is the simplest and cheapest structure for covering a garage.Features of the construction of a pitched roof are as follows:
Two boards connected along the wide side are often used as rafter legs, however the best option- use beams made of metal or wood with a cross section of 50*150 mm.
A pitched roof consists of the following parts:
- the base of the roof is the rafter system to which all other constituent elements are attached;
- sheathing is a support for the roof covering;
- elements that strengthen the rafter system;
- insulating materials that protect the structure from water and retain heat inside the structure;
- directly covering the garage roof.
The upper ends of the garage with a pitched roof must have a mauerlat or logs that support the rafters. They are attached to the walls using wire anchors. The anchors themselves can be embedded in the masonry or driven into the wall.
Such a structure can be covered with any type of roofing material: roofing felt, corrugated sheeting, soft tiles, etc.
How is a gable roof constructed?
A gable roof is installed over the garage if an attic is needed. The most common gable roof gable design is an isosceles triangle.
Rafter system gable roof can be performed in the following options:
Installing a gable roof is very simple, since its base consists of several rafters of identical sizes. The installation of the frame rafters is done sequentially, and then they are connected at the very top of the roof.
The roof support is the walls of the building. To correctly calculate the size of the ridge and rafters, you need to know not only the angle of inclination of the roof, but also the dimensions of the building. To accurately make a canopy, you need to add about half a meter to the length of the rafters.
Installation of a gable roof begins with the arrangement of trusses, which are assembled on the ground according to a template. The Mauerlat is installed around the perimeter of the building, and then it is attached to the wall using anchors. A layer of roofing felt is made between the Mauerlat and the wall.
Characteristic features of a sloping roof
A broken roof is a structure with numerous broken lines. In principle, this is a type of gable roof that allows you to create attic floor additional room.
There are the following types of broken roofs:
The reliability of the structure and its comfort depend on the type of roof chosen. However, sloping hipped roofs are becoming most popular today, since they ideally combine two features: the effective use of additional space and the low complexity of installing the rafter system. This approach involves obtaining full-fledged living quarters with small financial investments.
Polyline device hipped roof garage allows you to create full-fledged living quarters on the second floor To build a sloping roof, it is necessary to make a fairly dimensional structure of the rafter system, however, during its construction, modular installation methods can be used, so it is not necessary to use different lifting equipment. The rafter system and racks are cut at the desired angle in those places where there are fractures in the slopes. To secure the nodes, you need to use “kerchiefs” made of plywood with maximum thickness 2 cm.
This design of a hipped roof is perfect for small-sized garages, where it is not possible to construct a sloping roof of a more complex shape. For buildings with large areas, a different rafter system is installed.
Used garage roof
An exploitable roof is a structure flat shape, which has a special coating. A similar structure can be built over the entire area of the building or over some part of it.
The roof in use is conventionally divided into the following types:
The construction of such a roof must comply with the standards specified in SNiP, since the operating time of the roof depends on the correctness of the selected materials, the calculations performed, and the consideration of loads.
Typically, the roof structure has a multi-layer structure, and it is done in this way:
- rigid base;
- required layer vapor barriers;
- insulation;
- screed under right angle;
- waterproofing layer;
- protective separator;
- finishing coating.
An existing roof can also be constructed using granite gravel (fraction 25/32 mm), which is laid on geotextiles. In order for the roof to operate normally, gravel is laid with a thickness of at least 50 mm. Geotextiles in parallel with gravel will make the coating more stable.
The undeniable advantages of a sliding roof for a garage
Today, mobile sliding roofs, which have many advantages over traditional roofs, are of great interest.
According to its design, a sliding roof can be of the following type:
By functionality Sliding roofs are divided into:
- seasonal (the structure moves only during a certain period, usually in summer);
- permanent (used throughout the year);
- temporary (used for mobile light structures).
In addition, a sliding roof can be not only permanent, when the entire structure or a specific part of it is covered, but also attached over various buildings to the main house. Among other things, a retractable roof can also be designed over other free-standing buildings, for example, greenhouses, greenhouses or observatories.
The main elements of a retractable roof are load-bearing profiles made of aluminum, which are manufactured with a variety of protective coatings in the form of:
- anodizing;
- powder paint;
- various enamels.
To give rigidity to the profiles, a steel pipe with a square cross-section is installed inside them. However, the most durable forms of sliding roof frames are considered to be:
- dome;
- arched;
- single-pitched with a slope angle of at least 45 o.
For other types of roofs, which have a slope angle of up to 45 o, only reinforced coverings and profiles are used.
The highest quality and effective options When installing a retractable roof, coverings made of plexiglass, triplex or tempered glass are considered. This type of panel can withstand hail up to 14 mm.
What types of materials are used for garage roofs?
A garage roof can be built from a variety of building materials, and their cost depends on the “thickness” of your wallet, and installation methods depend on the time you have. Therefore, it is worth thinking carefully about the type of roofing material for the garage.
A fairly popular and well-known material among consumers, which is affordable and easy to use. One roll is enough to cover 10 m2 of roofing and forget about it for 15 years. The main advantage of roofing felt is that this coating is inexpensive and durable, but for its use it is necessary to make a sheathing, as well as a rigid frame.
Ruberoid is one of the most inexpensive and popular materials for covering garage roofing Waterproofing is considered high quality provided that it is made of at least four different layers and uses different types roofing felt
Corrugated sheet
This is a modern material that is replacing slate, since the service life of corrugated sheets exceeds half a century. When deciding how to cover your garage roof, consider purchasing load-bearing wall material of the NS brand. The wavy profile of the sheet is made using cold rolling. All types of corrugated sheets have an identical wave-like trapezoidal shape, but the size and height of the material differs for all brands.
Corrugated sheeting is one of the most popular materials for garage roofing because it is lightweight and lasts at least 50 years Corrugated sheeting is a durable, fireproof, as well as water and soundproof roofing material that meets government standards. Its advantage lies in the possibility reuse.
Slate
Traditional slate is often used for garage roofing, as its service life is about 40 years at a moderate cost. The material is an asbestos-cement board, which is quite simple to install - holes are drilled into which galvanized nails are driven with an allowance of a couple of millimeters. Further, the installation of this material is carried out identically to the installation of a roof made of corrugated sheets with the only difference - the corners of the internal spans are cut off.
Slate is laid on the garage roof in the same way as corrugated sheeting and secured with special slate nails Roof tiles
The garage roof can also be made of cement-sand or ceramic tiles. These types of natural coatings last approximately 100 years and are characterized by resistance to ultraviolet radiation, fire resistance and the ability to withstand a variety of temperature changes. In addition, the tiles perfectly absorb noise, do not retain static voltage and have low thermal conductivity.
For laying tiles on gable roof special locks are used on each product If a roof is being built with a slope of about 12 degrees, then metal tiles are the ideal option. The flooring is made of galvanized steel 0.6 mm thick, which is coated with a polymer composition. To give the material its shape, it is stamped. Metal tiles are sold in a varied palette of colors.
Metal tiles are laid in large sheets, often corresponding in length to the dimensions of the slope Seam roof
Metal is the lightest building material, allowing you to save money when installing the frame. Of course, when maintaining a metal structure, you will have to spend a lot of money, but this material is suitable for any type of roof. For example, planning to build metal roof, when arranging it, you can only get by with a sheathing made of beams.
To create a seam garage roof, special tools are used to form a sheet fastening profile Installing a seam structure requires the use of special equipment and the involvement of professionals, since even minor “punctures” in the calculations will lead to distortions, which are much more difficult to eliminate than to immediately build the roof correctly.
How and how to insulate a garage roof
Every motorist dreams of a warm garage, and making the roof insulated is quite simple.
IN modern construction The roof of the garage is insulated in combination, that is, traditional insulation is combined with a heat insulator that reflects light and does not let in infrared radiation. However, in some cases such costs may be unreasonably high, for example, if the building is detached. Then use classic materials, such as:
- Mineral wool. She has wonderful technical characteristics. It is used only with hydro- and vapor barrier material, which protects mineral wool from water. In addition, mineral wool is quite affordable.
Mineral wool is inserted into the cells between the rafters and secured with wire or fishing line before the final ceiling covering is laid - Glass wool. This material is cheaper than other insulation materials, but has a low degree of fire resistance. If you plan to make a pitched roof, then it is better to buy a special type of glass wool, which has a high density structure. This material is produced in rolls with a width equal to the normal distance between the rafter legs.
Glass wool is one of the most inexpensive and accessible materials for roof insulation - Styrofoam. This is a waterproof material that is thermal insulation characteristics similar to mineral wool. Polystyrene foam is a flammable insulation material, but the PBS-S brand with the addition of fire retardants has the property of self-extinguishing. Due to these features of the material, it is used as insulation for garage roofs. In addition, it does not rot, mold and mildew do not form on it.
Laying foam plastic in the sheathing of a garage roof does not require special skills - Penoizol. It is a liquid foam, but with best performance. It is resistant to fire and water, hardens when placed in a confined space, and forms an ideal seamless coating. With all this, penoizol is cheaper than any sheet foam, and its service life is about 40 years without loss of characteristics.
To insulate the roof with foam insulation, it is necessary to use special equipment for spraying
You can also apply traditional options to insulate a garage roof, for example, use sawdust, but with modern materials they don't compare.
The garage space is an object with a high probability of fire, so it is necessary to purchase insulation with improved fire resistance characteristics.
Insulating the garage roof from the inside
Required tools:
- special buttons or furniture stapler with staples;
- vapor barrier film;
- carpentry tools;
- self-adhesive tape;
- waterproofing;
- insulation.
Thermal insulation of the roof from the inside is carried out as follows:
Such a cake is placed not only on wooden beam structures, but also on reinforced concrete slabs. Before installation, the beams are protected with sheet material, after which waterproofing is attached to it, then insulation and vapor barrier.
Do not allow the waterproofing film to come into contact with the insulation; there must be a certain distance between these materials for ventilation. Direct contact is only allowed if a superdiffusion membrane has been used.

We insulate the garage roof from the outside
The roof is insulated from the outside during the construction stage, since it is not very convenient to open it already finished building in order to correct shortcomings. Please note the presence of a vapor barrier, which must be installed on the side of the room. This way you can prevent not only re-condensation of vapors, but also avoid unpleasant leaks.

How to repair a garage roof
Leaking is the main nuisance that a garage roof brings, and the reasons for this may be:
- exhaustion of the strength resource during operation;
- negative impact of weather;
- incorrect roof installation;
- mechanical damage due to careless cleaning of the roof from snow cover;
- low quality finishing material;
- neglect of the installation of waterproofing;
- violation of installation standards when using roofing material.
Leaks must be eliminated at the stage of mold or wet spots appearing. Initially, it is worth checking the joints and joints, then the integrity of the roof for holes, chips or other damage. In addition, it is necessary to eliminate various types of blockages, such as dry leaves that clog the corners of the roof and accumulate moisture.
The method of eliminating a leak depends solely on the amount of damage and the characteristics of the roofing material. Partial repairs can be carried out for small-piece and soft roofing materials. Scope of repair work for panel and sheet material depends only on the complexity of the structure and its damage.
Using roofing felt, you can quickly and inexpensively completely repair your garage roof and get rid of leaks When preparing drawings and a garage roof project, immediately include in the estimate an extra 10% for other expenses that are difficult to foresee.
