On modern market presents a huge range of construction and finishing materials, including for roofing. Primitive finishing such as slate and bitumen is gradually becoming a thing of history, being replaced by more presentable and quality materials, fully meeting the requirements of modern housing construction.
Corrugated sheeting is one of these high-quality and aesthetic materials. You can cover the roof with corrugated sheets yourself. Here is a guide to arrangement of flat roofs. Similar roofing structures very often they are erected on various outbuildings such as sheds and gazebos, and sometimes above residential buildings.
An inexperienced person may decide that the corrugated sheet is not in the best possible way suitable for roofing and can only be used for cladding gates and fences. However, this opinion is absolutely wrong. Modern profiled sheets have excellent protective properties, excellent appearance and available in a wide range of colors.
Add to all the advantages the ease of installation and fastening of sheets, as well as an affordable cost, and you get almost perfect material for roof roofing.
It is precisely for the ease of installation that private and thrifty developers are so fond of profiled metal sheets. However, you should not think that covering the roof with the material in question with your own hands is very easy. Here, as in any other work, there are a number of important nuances, which must be taken into account, especially when working with flat roofing structures.
The nuances of using corrugated sheets when working with a flat roof
Flat roofing is mainly used to cover various kinds outbuildings. When installing corrugated sheets on such a roof, a number of features must be taken into account, first of all, the low slope of the roof slope.
To cover a flat roof, use a single sheet, without joints. Any joints increase the risk of moisture penetration into the space under the roof. If it is not possible to equip the roof with one sheet, the joints must be sealed with special silicone agents.
It is precisely because of the features mentioned above that corrugated sheeting is very rarely used for roofing flat roofs. For similar designs better fit roll material s, however, if you really want to, you can successfully lay corrugated sheets.
Features of the technology
In accordance with the technology, profiled sheets must be laid at a certain angle necessary to obtain the highest quality and reliable coating. If you have at least once had to install a roofing covering with your own hands, you already know that the mounting angle finishing material determined by the angle of inclination of the roof slope.
In the case of a flat roof, certain difficulties may arise at this point. Profiled sheets are laid at a ten-degree angle. With a smaller slope, atmospheric moisture will not be able to drain normally from the roof and will penetrate under roofing material, especially if the sheets are laid overlapping. Solve the problem of creating the required slope in the case of flat roof in most cases, lathing helps.
In addition to the slope of the slope, it is necessary to take into account its length. As a rule, profiled sheets have a standard length of 12 m. This sheet size is very convenient - in most cases, the entire roof slope can be covered with one sheet, avoiding seams and any kind of joints.
If necessary, the corrugated sheet can be easily cut using ordinary metal scissors. It is strongly not recommended to use a grinder for cutting roofing sheets. During the operation of this tool, it produces a large number of heat, under the influence of which protective covering the corrugated sheet is destroyed, which is why the performance properties of the material noticeably deteriorate.
Roofing Guide
With a profiled sheet device on flat roof you can handle a barn, gazebo and any other building with your own hands. The technology for doing the work remains almost the same for most cases.
First stage - tools
Prepare the following equipment for work:
- electric drill. If possible, use a drill with a low chuck speed. This will allow you to set the angle of entry of each fastener into the roof surface as accurately as possible;
- jigsaw Instead, you can use scissors for working with metal or a hacksaw. Cut sheets roofing grinder is categorically not recommended. As a last resort, when no other tools are available, cut with a grinder using a special attachment for processing corrugated sheets;
- brushes;
- lathing boards;
- hammer.
Second stage - lathing
Start assembling the sheathing. To arrange this element, it is most convenient to use boards. Lay the boards on the rafters and secure them with galvanized screws or nails every 50-100 cm.
Select the specific pitch of the sheathing in accordance with the characteristics of the profiled sheet used. For example, for installation of profiled sheets C35 optimal step the lathing will have a value of 0.5 m, and for sheets of grade C44 the pitch of fastening the boards must be increased to 70-75 cm.
If the length of the roof slope exceeds the length of the profiled sheet, lay additional boards at the future joints of the sheets.
Treat the finished sheathing with an antiseptic. You can perform this processing before you start attaching the boards - as is more convenient for you.
The third stage - moisture insulation
The basis of profiled sheets is metal. Condensation inevitably settles on metal surfaces. Moisture sooner or later leads to irreversible damage to any building materials, so it must be neutralized. There are 2 main options for neutralizing the harmful effects of moisture, namely:
After completing the moisture-proofing work, you can begin to prepare directly for the installation of the roof. To make it more convenient to lift sheets onto the roof, you can make a simple device in the form of two long slats laid from the ground to the roof at a slight angle.
It is more convenient if you have three assistants, so that two feed the sheets from below, and two receive the material from above and carry out its installation.
The fourth stage - laying sheets
First of all, select suitable option installation of profiled sheets. There are two main mounting options, namely:
Corrugated sheeting can only be fixed using special galvanized self-tapping screws with seals. The seal must be made of neoprene rubber. This material tolerates contact with moisture and temperature changes well. Optimal diameter self-tapping screw for attaching corrugated sheets – 4.8 mm.
Nails cannot be used to fix corrugated sheeting. With constant gusts of wind, the nails simply will not be able to hold the sheets properly, as a result of which they will be torn off from the sheathing.
Self-tapping screws are screwed into the depressions of the sheets, where the material is adjacent to the sheathing. On square meter coating, about 6-8 self-tapping screws are consumed. Try to place fasteners at the same distance. The sheets must be attached to the outer battens in all waves, because these places will be subject to the strongest wind loads. The sheets can be fixed to the remaining elements of the sheathing through one wave.
It is better to prepare mounting holes in sheets in advance. When working with thin profiled sheets, holes can be made using a self-tapping screw, but if the sheets are quite thick, make holes with a drill.
Self-tapping screws with multi-colored caps are currently available for sale. Without any problems, you can choose fasteners that exactly match the color of your profiled roofing sheets.
Lay adjacent sheets of covering with an overlap in 1 wave.
Cover the entire main surface with corrugated sheets, and then install additional accessories if necessary.
Thus, there is nothing complicated about covering the roof with corrugated sheets yourself. You just need to follow the instructions and take precautions that are relevant for any roofing work.
Good luck!
Video - Cover the roof with corrugated sheets with your own hands
This article will be useful for those who want to make a roof from corrugated sheets with their own hands. We will give step by step instructions, which will help you do the roofing yourself without spending extra money on hired workers.
- If the roof slope is more than 15 degrees, the corrugated sheets should be laid on top of each other with an overlap of 200 mm.
- If the slope is from 15 to 30 degrees, the overlap should be the same or 50 mm less.
- It is advisable to use silicone sealants, especially if the roof slope is up to 20 degrees.
Before you begin to strengthen the corrugated sheets on the roof, you need to make a lathing.
It is most convenient to make it from wooden blocks. They are easier to install, and their price is significantly lower than their metal counterparts.
To make the sheathing, you can use beams made of alder, oak, aspen, spruce or pine. Before you begin installing the beams, they need to be treated with an antiseptic so that fungus does not appear on the roof in the future. The boards also need to be impregnated with a fire-resistant compound. At this stage of construction, special membranes can be installed that will protect against steam and moisture penetration.
Start of installation
First you need to install the upper and lower bars, located across. The structure can be assembled using nails or self-tapping screws if it includes metal elements. If the beams have to be attached to concrete, then dowel-nails can be used. It is most convenient to start installation from the bottom, gradually moving up. The step between the bars should not be more than 50 cm.
Vapor barrier
Vapor barrier is usually done on the roof of the building that will be heated. It serves to prevent moisture from accumulating under the roof. Most often, vapor barrier is a special film that has special membranes that prevent the passage of moisture and release steam. This film is installed before you begin laying the corrugated sheet. Vapor barrier sheets are laid overlapping, sticking to the roof with special self-tapping screws. You can make an overlap on the wall.
When the sheathing is ready and the insulation is done, you can install the corrugated sheets.
What is corrugated sheeting?
These are stamped sheets of zinc coated steel. They are quite light, able to bend, but at the same time durable. Thanks to these qualities, the sheets are excellent for roofing. Corrugated sheeting is suitable for any type of roof, regardless of how many slopes the roof has and what its slope is. They can cover residential and commercial premises.
Corrugated sheets are available in various sizes. They have different ribs and can be covered with special enamel, or without it. Don't forget to allow the film to sag a little. This is necessary to be able to ventilate the room. It is better to take the film together with which bitumen mastic can be used.
If you use rolled material, that’s okay, but the sheets will need to be placed very tightly in relation to it. Laying the material will need to be done perpendicular to the location of the corrugated sheets.
How is a corrugated roof installed?
Before you start work, you need to take care of your safety, since the work takes place at height. In order to prevent accidents, you need to:
Use ropes for insurance and use special belts for installation.
If the roof slope is large, you need to make a protective fence.
Use shoes with non-slip soles.
Do not install the sheets in the rain as they can become very slippery.
Shoes should not have hard elements. Stepping on the sheets can damage their protective coating. If possible, avoid stepping on them.
The damaged coating can be coated with a compound that is sold in hardware stores to restore the protective coating of sheets.
Direct installation
Most often, sheets of corrugated sheets are attached to each other with special self-tapping screws, which have a wide head with a rubberized skirt. If you use nails, they must be special: they are distinguished by a wide head and a rubber skirt. It is needed to ensure that the metal body of the nail does not scratch the corrugated sheet, and also to prevent moisture from entering the hole. The gasket can be made of polymers, but rubber is considered more reliable. It is best to treat the place where the screw is screwed in or a nail is driven in. sealant. The same is done with the seams that are formed from laying corrugated sheets on top of each other. This is done so that moisture cannot get under the sheets even at the molecular level.
If the corrugated sheet is too large and does not fit, the excess can be cut off using a hacksaw. You can use metal scissors, but they rarely cut accurately. Scissors are convenient for cutting small parts, but not large leaf. Great if you have it at your disposal electric cutter. They can quickly cut perfectly even pieces, giving the sheet the required shape. Also suitable for this purpose Circular Saw, but you need to choose the right disk.
When cutting the sheet, do not use a grinder. This saw heats up the corrugated sheet material too much, causing the steel to become brittle and may begin to rust over time. Using this tool you will destroy protective layer sheet and ruin the factory-applied insulation layer. This will lead to the fact that the corrugated sheeting will quickly become obsolete, and you will have to repair the roof, which begins to leak.
Sheet attachment point
How to attach corrugated sheets to each other?
Start installation from the bottom corner of the roof end. The bottom row is laid in such a way that its edges hang from the roof by about 4 cm. The first row is secured with self-tapping screws. The point where you need to screw in the screw is the bottom of the wave. Screw the screws into the waves one at a time.
When working with the sides of a building, you need to use wind corners, which are used to sew up the boards at the ends. Sheets can be mounted both lengthwise and crosswise, it depends on which method is more convenient for you personally. The sides need to be sewn up with a special sheet after you have laid the entire row. All sheets of corrugated sheets should be overlapped.
If the direction of the sheets is vertical, then the top sheet should cover the bottom sheet by at least 20 cm. If the wave pitch does not allow this, you need to overlap more, but in such a way that the waves coincide.
When placing corrugated sheets horizontally, the sheet located on top must overlap bottom sheet per wavelength. If you use a gasket-seal, it is better to overlap the length of two waves.
If the roof slope angle exceeds 16 degrees, it is necessary to use a sealant.
What is a seal?
This is a special gasket that is needed to prevent snow from getting stuck between the sheets of corrugated sheets. It also protects from wind and rain. The point is that the sealant forces the corrugated sheets to fit tightly to the sheathing. Seals are sold ready-made. You need to choose them based on the waveform of your corrugated sheet.

How to properly fix corrugated sheets on the roof?
Laying sheets should begin from the edge. One sheet is attached from the center of the edge using self-tapping screws. It’s better to secure it with one self-tapping screw for now. This is done for the purpose of being able to correct the sheets. The following sheets are attached to it with an overlap and are also fixed with one self-tapping screw. This is done so that the row can be corrected if it turns out to be uneven. The sheets can then be secured securely.
After the row is corrected, you need to secure the sheets along the crest of the wave, and the joints are fastened with one self-tapping screw onto two sheets. This is done in each recess of the wave.
The first sheet is fastened in the following way: the longitudinal connection is made along the crest of the wave, the pitch is 500 mm, and the vertical joints are attached at each bottom of the wave.
The places where the screws are screwed are indicated in the figure.
For one meter square you will need about five screws. This consumption is the most optimal.
Installation of the ridge and end strips should be carried out only after the main sheet is securely fastened.
The most difficult thing is to install corrugated sheeting in places of contact with the wall. This part of the work is carried out in last resort, as well as the installation of chimneys.
Pay attention to how the screw is tightened. Don't leave it hanging loosely, but make sure it doesn't bend the sheet. Correct location The self-tapping screw is shown in the picture.

How to properly cover a roof with corrugated sheeting: finished roof
Corrugated roofing has a whole range of significant advantages:
- durability;
- reliability;
- strength;
- resistance to all types of atmospheric influences;
- very elegant and attractive appearance.
In addition, corrugated sheeting is quite easy to use and unpretentious to small flaws in the work, typical for beginners or inexperienced installers.
Selection of materials and calculation of their required quantity
A do-it-yourself roof made of corrugated sheets can be made from both roofing and wall corrugated sheeting. These two types differ in thickness steel sheet and features of the profile shape. The main external difference between wall corrugated sheets is the presence of one or more additional longitudinal grooves, which increase the rigidity of the material.
Which corrugated sheet to choose
For small roofs, corrugated wall sheeting is sufficient. When covering large surfaces or with sparse sheathing, it is better to use roofing corrugated sheeting (it is more durable, the profile height is from 20 mm), although this increases the cost of the roof. Application more durable coating makes sense for peaked roofs that are subject to increased wind loads.
It is best if the length of the sheet is equal to or greater than the length of the roof slope. This will greatly reduce the number of joints, save on fasteners, and reduce labor intensity and time spent on work.
How to calculate the amount of material needed
The cost of a metal roof is quite high, therefore, even at the preparation stage, you should calculate as accurately as possible the required quantity of all its components. As practice shows, the material must be taken with a small reserve, since the exact volume of waste is almost impossible to determine in advance.
Calculation of sheets
Calculation required quantity sheets for covering the roof are carried out individually in each case. This takes into account the overlap area and effective area leaf. It is considered the most accurate graphic method calculation, in which a plan of the roof slopes is made on graph paper and all sheets are marked on it.
- When the slope of the roof plane is less than 15 degrees, the sheets must overlap by more than 20 cm;
- A slope of 15 to 30 degrees corresponds to an overlap of at least 15 cm;
- On peaked roofs with a slope angle of more than 30 degrees - 10-15 cm.
Overlapping areas of corrugated roofs on almost horizontal roofs, with a slope slope of less than 12 degrees, must be coated with a special bitumen, silicone or polyurethane sealant from brands such as Favorite, Bau Master, Macroflex, Liquid Nails. The fact is that water and melted snow are poorly drained from a sloping roof and in this case only a sealant can protect wooden sheathing from excess moisture.
Fastener selection
To install corrugated sheets, special hardware is used: self-tapping screws and self-tapping screws. The latter are used much less frequently, since they require pre-drilling holes in the sheet. Self-tapping screws for metal have a drill at the end. Thanks to this design, they themselves drill a hole in the metal and then, using threads, go deeper into the wood.
To attach the decking, the diameter of the hardware must be in the range of 4.8 - 6.3 mm. The length is chosen so that the screw in no case goes through the sheathing board. Otherwise waterproofing membrane will instantly burst in this place.
The hardware intended for fastening the corrugated sheeting is painted the same color as the roof, so it does not stand out at all against its background. The self-tapping screws are supplied with sealing neoprene washers. They are necessary for the protection and durability of the roof: without them, the wood under the fastening will quickly get wet and rot.
The hexagonal head is oriented to the same screwdriver attachment. In order not to push through the metal, its lower plane has an enlarged area.
The screw head is usually made in the shape of a cone, which does not press, but pushes through the metal and greatly reduces the area of the holding contact. When using screws, in addition to a sealing rubber or polymer gasket, it is recommended to additionally protect the hole with silicone or sealant.
We will tell you how to attach corrugated sheeting to the roof using self-tapping screws in the photos you see, using the example of a sheet with a rectangular profile. On average, on a flat section of a flat roof, from 6 to 10 hardware are used. This amount varies depending on the design of the sheathing, the angle of inclination and the location of the corrugated sheet: in the outermost sides, self-tapping screws are installed in the two outer recesses of the wave. In the middle part of the roof they are used in a row. The installation pitch of self-tapping screws is at least 500 mm. After receiving required quantity, the number of hardware needs to be increased by 1.15 times.
Laying corrugated sheets
There are many variations in laying corrugated sheets. But the most common and reliable method- layer-by-layer horizontal. Let's look at how to cover a roof with corrugated sheets with our own hands using the example of the simplest and most available method.
Operating procedure
We check the horizontal level of the lower cut of the sheathing along the eaves strip with a level. If it is tilted towards the horizon, when laying the first sheet we make a small release below the bar. There must be a ventilation gap between the strip and the vapor barrier. Without it, the sheathing will very quickly gain moisture and begin to rot.
- To understand how to cover a roof with corrugated sheets with your own hands correctly, you should take into account that work on a pitched or gable roof starts from any edge, and the complex hip roof is covered from the center of the hip.
- The first two or three sheets are pre-attached roughly (the screw is not driven in completely). And only after checking the horizontal lines are finally fixed. Each subsequent profiled sheet overlaps the previous one. The higher rows, like scales, overlap the top of the lower rows.
- If it is not possible to fit the edges of the topmost sheets to the ridge, they are cut in place using electric scissors or hand tools. Please note that you cannot use an angle grinder for this purpose! It greatly overheats the metal and destroys the protective coating at a distance of several centimeters from the cutting site.
- When using screwdrivers, it is important to set the correct screw force. It is necessary to ensure a tight tightening, but to avoid pushing through the metal profiled sheet. The screwdriver head should not protrude beyond the protective plane of the screw. Otherwise, the coating that protects the metal may be damaged during operation. Rust streaks will very quickly appear in this place, and the corrugated sheet will begin to corona and collapse.
- The junction of the roof slopes is covered with a special ridge strip to match the color of the corrugated sheeting. For peaked roofs, a ventilated fastening design can be recommended. But its installation requires certain knowledge, so the strip can simply be secured through a seal on top of the corrugated sheet. Ventilation will be provided by the design of the profiled sheet.
- The final stage will be tapping the end strips. Typically, these products have a two-meter length and a shelf width sufficient to cover two waves of corrugated sheeting. The plank is attached to the overlap of the roof, also covering the end wooden board. At this point, do-it-yourself roofing with corrugated sheets can be considered complete.
Corrugated roofing safety instructions
- As with any work at height, safety on the roof is ensured by safety ropes and anchorages.
- You should wear soft shoes with rubber soles on your feet.
- It is strictly forbidden to carry out roofing on a windy day! Corrugated sheeting can “catch” the wind and blow away everything in its path.
- It is easiest and safest to feed corrugated sheets onto the roof from the ground. inclined boards using a winch.
- On a hot sunny day, the metal heats up to 80-90 degrees or more. Therefore, it is better to wear durable gloves when working on the roof. In addition, the cut edge of the metal is dangerous, and mittens protect your hands well from cuts.
- When walking, do not step on the ridges of the corrugated sheet. They can become crushed under the weight of a person, causing you to lose your balance.
Bottom line
Covering a roof with corrugated sheets with your own hands is quite easy and quite affordable for each of us. With careful preparation and a responsible approach to this work, a roof made of corrugated sheets with your own hands will last no less than as a result of the work of professional craftsmen.
Corrugated sheeting is a universal building material that is used for a variety of purposes. More and more often you can see elegant and very attractive roofs covered with bright sheets of corrugated sheets. Mostly there are monochromatic coverings, but there are also geometric patterns in the form of stripes and rectangles, which give the roofs of a house special style and individuality.
How to cover a roof with corrugated sheeting and how to properly care for the corrugated sheet? Once you become familiar with the features of this process, you will be able to work with this coating yourself.
Advantages of laying corrugated sheets on the roof of a house
Before considering the features for the roof of a building, let’s determine the advantages of such a material. Before starting work, many people wonder how to cover the roof with corrugated sheets in such a way as not to attract expensive construction crews. This is precisely one of the most important advantages of this coating - we make this kind of roofing ourselves.
Two or three people will be enough, even if they do not have special knowledge. Roof installation is very simple, its rules are accessible even to beginners. at home or you can arrange it from scratch in a couple of days.
The question of how to make a corrugated roof strong and reliable disappears immediately if you study the characteristics of this material. Corrugated sheets are made from cold-rolled metal sheets, which are often coated with polymer on top.
The thickness of the material makes it resistant to wind loads, and the paint layer prevents precipitation and corrosion from damaging the coating. So the installation in this case will be reliable.
The cost of the material differs in availability, as well as the quantity of all additional materials for the roof of a house.
Thus, the questions of how and how reliable it is are resolved very simply.
Features of self-laying corrugated sheets
How to properly cover a roof with corrugated sheeting and close it interfloor ceilings? Installation using corrugated sheets is quite simple, but there are still some features that need to be taken into account. These include delivering the material and lifting it onto the roof of the house - care must be taken so as not to scratch or damage the profiled sheets for the future roof. It is also important to cover the sheathing correctly and carefully.
We must not forget about safety: when we ourselves begin to work with metal, it is necessary to wear protective gloves and clothing; you can only walk on the roof in soft shoes, stepping on the ridge.
It is important to correctly determine the type during installation rafter system and the pitch of the rafters, the performance will be influenced by the overhang angle and the type of profiled sheet. We cover the roof of the house, taking into account these parameters.
Laying rules
Installation of sheets and arrangement of the roof are simple. First, we need to determine the installation option. Next, we make a boardwalk under the valley planks and attach the end strips.
Roof installation begins with laying cornice strip, which should be below waterproofing film. After this, we start from the end, in cases with hip roofs– we start from the center of the hip. For fastening, one sheet requires from seven to eight self-tapping screws; some joints are recommended to be processed using steel rivets.
All sheets must be aligned before final strengthening along the end of the roof slope! The overlap of the material, depending on the angle of the slope, will be from one hundred fifty to two hundred millimeters, it should not be less than one wave.
Installation of corrugated sheeting near valleys, ridges, pipes
The technology for laying corrugated sheets involves the design metal sheet places near valleys, pipes, roof ridge. Let's look at how you can do this yourself.
- Gutter device dormer window, that is, the design of a short valley. To do this, we ourselves cut the sheet at the lower end of the groove into two equal parts (we take this into account when calculating the material for installation). First we install the bottom sheet, then the bottom strip, and the last is the roofing sheet.
- We install the end strip ourselves. The length of such a plank is two meters, the overlap of the material should be from fifty to one hundred millimeters. Installation begins from the overhang side towards the ridge of the roof. Around the ridge, the excess must be cut off, all end strip At the same time, it covers no less than one wave of corrugated sheeting. Now the bar is attached to end board and profiled sheets in the ridge, the fastening step is one meter.
- Installation of ridge strip. Here you can use special smooth elements for skates; experts recommend laying seals under the corrugated sheets, either repeating or with fine corrugation. The length of the overlap should be from one hundred millimeters; on the sheet side, the plank is attached using self-tapping screws in increments of up to four hundred millimeters. All fastenings that we make ourselves must go into the groove or under the casing. For protection we use a ridge seal: for a lateral connection we take a longitudinal seal; on steep slopes it can not be used.
- Installation of pass-through elements or outlet pipes. All outlet pipes, which we also install ourselves, consist of an upper part (the pipe itself) and a lower part (selected according to the roof profile). It is advisable to immediately install a snow barrier. The diameter of the pipes should be about one hundred millimeters, ventilation pipes needs to be insulated.
Seals and screws for corrugated sheets
So, let's cover the roof of the house. The technology requires the use of special screws and seals. Self-tapping screws are made of galvanized, hardened steel. They have a special gasket made of EPDM elastomer, their caps are made of polyester, thermally strengthened powder, which guarantees highest quality, corrosion resistance, mechanical damage, ultraviolet rays.
Corrugated sheet fastening diagram.
The technical characteristics of the self-tapping screws are as follows:
- dimensions – 35*4.8;
- surface treatment – electrolytic galvanization from 12 microns;
- self-tapping screws contain stabilizers that help prevent aging during negative impact ultraviolet rays;
- outer covering of the cap powder paints thickness from 50 microns;
- Gaskets can be made of polymer or aluminum sheet (for valleys).
Often involves the use of special gaskets that serve as protection from snow, rain, wind, preventing them from falling under the surface of the flooring, due to the tight fit of the material to the planks. This increases service life truss structure, insulation, interior decoration at home, sound and wind insulation is greatly improved.
Today, installation can be carried out using seals that match the shape of the corrugation of the flooring. In addition, there is a special seal for the ridge for 1.1 meters, reverse for 1.1 meters, universal for two meters, at an angle of forty-five degrees for 1.05 meters.
Care of roofing sheeting
Covering a roof with corrugated sheets with your own hands is not difficult, as is caring for it. For cleaning, rain is enough to make the surface clean again, but leaves, branches and other debris sometimes cannot be completely washed off with rainwater, so annual cleaning of the surface is recommended.
In the same way, it is necessary to regularly clean drainage systems and gutters. Areas that are stained or heavily soiled should be washed with a soft brush and plain water from a hose under a pressure of up to fifty bar.
If the dirt is sufficiently ingrained, you can use detergents for painted surfaces. We do it ourselves this way: apply the product to the surface of the roof, then give it a couple of minutes for a better effect and wash off clean water. We clean difficult stains with a clean rag soaked in solvent. After this, the roof must be rinsed with clean water.
Attention: we do not use products for cleaning the roof that are not intended for similar works, since the surface of the polymer and the sheet itself can be damaged too much.
We remove snow and ice ourselves using plastic or wooden shovels; this must be done carefully to prevent scratches from occurring during cleaning.
Thus, the installation of corrugated sheeting differs from many other options in its simplicity, although it also has its own characteristics. Must be strictly followed simple rules laying, correctly calculating materials and taking into account the features of the rafter system. All that remains is to cover the sheathing with a corrugated sheet, and you don’t have to think about repairing the roof.
The profiled sheet is actually universal building material. It is widely used to implement the most different ideas. Nowadays, it is very common to find attractive and elegant roofs that are covered with bright profiled sheeting.
General information
In most cases, you can see plain ceilings. However, there are also geometric patterns in the form of rectangles and stripes. Thanks to this, the roofs of houses have their own special style. Some homeowners are wondering: how to cover a roof with corrugated sheets with your own hands? In addition, many do not know how to care for it. IN in this case It is recommended that you familiarize yourself with all the nuances inherent in this material. After this, you will be able to work with it yourself.
Clear benefits
Laying corrugated sheets on the roof has its own characteristics. Before installing it, you should familiarize yourself with the advantages of this material. Many people would like to do all the work themselves. This is not surprising, since currently hiring a professional team of workers is quite expensive. In this case, you can do without it. laid, is a completely doable task. This is the main advantage of this material.
Additional Information
End element
The length of the bar is about two meters. The recommended overlap of the material is 50-100 mm. The installation itself should begin from the plumb side. Next you need to move towards the ridge of the roof. Near it you need to cut off the excess. The entire end strip must be covered (at least one wave of corrugated sheeting). Next, it will be necessary to attach it to the corresponding board, as well as to the comb. The recommended step is 1 meter.
Ridge strip
In this case, specialized smooth elements are used. According to the recommendations of experts, sealants should be placed under the corrugated sheet. They should be finely corrugated or follow the profile of the roof itself. The recommended overlap length is from 100 mm. On the side of the sheet you need to secure the strip using self-tapping screws. The recommended pitch is 400 mm. Each fastening made independently must be under the casing or in the groove. In this case, the ridge seal is used for protection. The lateral connection is arranged somewhat differently. For these purposes, a longitudinal seal will be required. It can not be used on steep slopes.
Pass-through elements
Each outlet pipe consists of two parts: upper and lower. The latter is selected in accordance with the roof profile. It is recommended to install the snow plow immediately. The recommended pipe diameter is 100 mm. Ventilation elements need insulation. Here's how to cover a roof with corrugated sheets.
Some rules of care
In principle, this process is also not particularly complicated. In order for such a roof to be cleaned, ordinary rain will be quite enough. However, water is unable to carry away branches, leaves and other debris. For this reason, regular cleaning of the surface is recommended. This must be done every year. Drainage systems also need regular cleaning. This also applies to grooves. Heavily polluted areas are common. They can be washed with a soft brush. This can also be done with water from a hose.
