How to properly lay a roof with ondulin. How to easily cover a roof with ondulin with your own hands? Prices for ceramic tiles

The construction of the roof is the last stage construction own home before the beginning interior decoration and connecting communications. To reduce the time required for roofing work, you can install ondulin yourself. Ondulin – modern covering based on bitumen, the laying technology of which allows the material to be installed both on new roof, and to the old one without dismantling the design. It is suitable for roofs of any complexity, area and slope, therefore it is considered a universal option used in private and industrial low-rise construction. In this article we will tell you how to properly cover a roof with ondulin in order to obtain a durable, airtight coating that can withstand winter frosts and summer rains.

Ondulin is an inexpensive, technologically advanced roofing material that was invented in the post-war period in France for the quick repair or reconstruction of shell-damaged, dilapidated roofs made of traditional ceramic tiles, slate, and metal. The production technology of this coating consists of obtaining purified cellulose fibers, making sheets with a wavy surface from them, dyeing and impregnating them with petroleum bitumen. Coating the roof with ondulin makes the structure waterproof, resistant to temperature changes, impact-resistant, but at the same time lightweight. Due to the low weight of each sheet, installation of ondulin can be carried out on old roofing material without dismantling the structure. This material has the following advantages:

1. A light weight. Each sheet of standard size ondulin weighs only 6 kg, so making blood from this material does not require the establishment of a massive frame or strengthening of the foundation.
2. Easy to install. Do-it-yourself ondulin roofing can be done in 1-2 days without the involvement of hired workers, since such a covering can be installed without special tools and experience.
3. Flexibility. Sheets of this bitumen-based material have a certain flexibility, which simplifies the installation of ondulin on the roof complex shape, which have valleys, multi-slope slopes, ribs and dormer windows.
4. Affordable price. Installing a roof made of ondulin does not require large expenses from the homeowner due to the saving of lumber used to construct the frame and performing the installation on their own.

Important! Since ondulin was conceived as a repair material, it has a service life of 15-20 years and a relatively small range of colors. It comes in only 4 colors: red, black, brown and green. Before covering the roof with ondulin, it is necessary to take into account that this material fades in the sun due to the destruction of the pigment by ultraviolet rays.

Roofing device

Before covering the roof with ondulin, you need to understand the composition of the roofing cake that is made for this type of roofing material. The construction of a roof covered with molded cellulose impregnated with bitumen is not difficult due to its light weight. It consists of the following elements:

• Rafter frame. The roofing material is fastened to rafters made of natural wood with a cross-section of 50xx150 mm, the pitch between which is 50-80 cm. Since the material is light in weight, the frame is usually not weighed down with additional elements.
• Insulation. Before laying ondulin, thermal insulation material is laid between the rafters. Most often, mineral type insulation is used (basalt wool, glass wool, slag wool).
• Vapor barrier. The technology for laying insulation involves the use of a vapor barrier membrane, which protects the thermal insulation material underneath from steam penetration and getting wet.
• Waterproofing. To protect the wooden frame elements and insulation from possible leaks or condensation, a waterproofing film is laid. The waterproofing is attached to the rafter legs using a construction stapler.
• Counter-lattice. Before laying ondulin, counter-lattice slats are nailed on top of the waterproofing along the rafters, which create a ventilation gap necessary for air circulation inside the structure.
• Lathing. The type of lathing is specified step-by-step instruction on installation. Ondulin must be nailed to a continuous sheathing made of moisture resistant plywood or lattice from unedged boards, laid in increments of 10-15 cm so that the roofing material does not deform during operation.
• Ondulin. The roofing material must be nailed directly to the sheathing with special nails, overlapping the sheets over each other by 10-15 cm.

Please note that before covering the roof with ondulin, most professional craftsmen processing wooden frame elements antiseptic impregnations and fire retardants to protect against fire and rot.

Required materials and tools

Many inexperienced craftsmen wonder how to properly cover a roof with ondulin, and what is needed for this. The fastening of this roofing material is carried out without the use of special tools or expensive equipment, so installation is often done by hand. To build a roof from ondulin use:

1. Sheets of ondulin measuring 0.95 x 2.05 m are required to cover the entire roof area with a margin of 10-15% for trimming and overlaps.
2. Ridge profile for the entire length of the ridge, taking into account overlaps between elements of 10-25 cm.
3. Fastening elements. Special nails for ondulin with a rubber head are made of carbon steel and painted to match the material.
4. Beam with a section of 40x40 mm or 60x40 mm for the construction of sheathing, treated with an antiseptic.
5. Waterproofing membrane or film.
6. Sharp hacksaw for cutting sheets.
7. Lightweight nail hammer.
8. Screwdriver for fixing the sheathing.
9. Ruler, tape measure and construction pencil for taking measurements and markings.

Note! Before covering the roof with ondulin with your own hands, you need to establish scaffolding around the house or a high staircase that allows you to reach every corner of the slope.

Step-by-step manufacturer's instructions

Installation technology

Even without knowing how to attach ondulin, an inexperienced craftsman can easily cope with this task alone, since sheets of material are easy to process. However, do not forget that the reliability and service life of the roof depends on the quality of installation. The following step-by-step instructions are used for laying ondulin:

• First of all, you need to place and secure a waterproofing film on the finished rafters. To do this, it is rolled out and cut into strips of the required length, which are mounted along the slope perpendicular to the rafters with an overlap of 10-15 cm. The film is fixed to the rafters with a construction stapler, and the joints are taped.
• On top of the waterproofing material along rafter legs the counter-lattice slats are nailed down. To do this, use long nails or self-tapping screws.
• A sheathing made of 4x4 cm, 5x5 cm bars in 10 cm increments or a solid one made of sheets of moisture-resistant plywood is nailed on top of the sheathing.
• Next, they begin laying ondulin. Sheets of material must be laid with an overlap of 10-15 cm, starting from the bottom edge of the slope. The rows are mounted offset by half a sheet, maintaining a vertical overlap of 15-20 cm.
• The sheets are nailed to the sheathing with special nails with wide rubber heads. It takes about 20 fasteners to fix each sheet.

Not knowing how to install ondulin correctly, inexperienced craftsmen make mistakes when installing the roof. The main thing is to lay this material in dry, but not hot weather, since elevated temperatures lead to deformation of the sheets. It is forbidden to stand on the ondulin during installation, as it may break or change shape.

Video instruction

When choosing a roofing covering for their home, many owners, who are experiencing certain difficulties regarding the construction budget, try to find optimal material, based on the harmony of “price-quality” criteria. At the same time, owners who care about the appearance of the building being created probably have a desire to get away from the boring gray tones inherent, for example, in ordinary slate. And finally, the best option is from their point of view, I see a coating that can be installed independently, without resorting to the expensive services of a roofing crew. If we sum up all these criteria, then a good option would be practical implementation may become ondulin.

It must be said right away that the attitude towards this material is not entirely unambiguous, and sometimes even polar. He is praised “to the skies” and scolded mercilessly, sometimes unfairly attributing shortcomings unusual to him. Perhaps the “detractors” of ondulin once came across low-quality material, that is, an obvious fake, or the installation was carried out with serious violations of the technology established by the manufacturer.

Let's take a closer look at this roofing material: let's look at what it is, what characteristics it has, real advantages and has disadvantages, how to choose such a coating and how to attach ondulin to the roof with your own hands.

What is ondulin

To begin with, what is “ondulin”. After all, the name itself does not mean anything to an ignorant person, and even somehow “hurts the ears” in a non-Russian way.

A few facts from the history of the material

This name, in fact, is the name of the French company Onduline, which back in 1944 patented and began producing corrugated roofing sheets on a cellulose-bitumen basis. Post-war Europe required a huge amount of building materials to restore what was destroyed, and such coatings became a real godsend for this.

Ondulin was very widely used in Western Europe and even received the secret name “Euroslate”. Great demand for such roofing prompted the company's management to expand production capacity - ondulin production lines were launched in Germany and Italy, and sales offices were opened far beyond Europe.

The material came to the Russian market in 1994. Ondulin “fell right” with our homeowners, and taking into account the increased demand, the company opened a line for the production of the material in Nizhny Novgorod, with an estimated production capacity of up to 15 million roofing sheets per year. The plant carries out strict quality control, so the sheets Russian production are not inferior in any way howoriginal head products company enterprises.

Prices for ondulin

In addition to ondulin, the company also produces a variety of it, which is presented on the market under the name “ondura”. There is no fundamental difference in the structure of the roofing covering, with the exception of their geometric dimensions - ondur sheets are much larger in size, and they are more convenient to use on large-area roofs.

Another “competitor” of ondulin is roofing sheets of the “Nulin” brand. These are products of the American company Nuline Corporation, similar in production technology and again differing mainly in the geometric dimensions of the sheets. However, we can probably talk about competition not at all appropriate, since since 2010 the main assets of Nuline Corporation were acquired again by Onduline.

What and how is ondulin roofing made from?

One of the key advantages of such roofing material is that only “clean” materials from an environmental point of view are used for its production. The main components of ondulin are cellulose fibers and purified bitumen.

The source of cellulose fibers is waste from wood processing enterprises producing paper, cardboard and building materials from woodcomposite. Recycled raw materials – waste paper – are also widely used.

The purified cellulose mass is mixed with special mineral additives, which increase the plasticity of the mixture and the strength of the resulting material, and pigment dyes. Then the mixture is rolled into sheets, which are transferred to the pressing line. At this stage they are given a characteristic wavy shape, and at the same time, under a certain temperature conditions and calculated pressure, the resulting profiles are completely impregnated sheets with purified modified bitumen.

At the painting line, the sheets are given the required colors (matte or even glossy), single- or double-sided, after which the material, after drying, is cut with high precision into individual sheets, packed into bundles and delivered to the warehouse.

As you can see, the production process itself is not very complex. However, in this matter it is very important to strictly comply with all technological requirements at every stage. This is what becomes the key to the quality of the resulting material. There are many varieties of “Euro-slate” on the market, which, apparently, is produced with significant simplifications of technology. All this, of course, directly affects the quality and durability of the roof, and, most likely, the negative background in relation to ondulin is caused precisely by the use of such materials.

Main characteristics of ondulin

Since our article is devoted to working specifically with ondulin, only this material will be considered further, and not all similar ones, which often appear in colloquial speech under this name. However, this practically does not affect the installation technology of the roofing covering - it is similar for all corrugated sheets of this type.

So, under the brand " ondulin» Currently, two types of roofing sheets are produced: “ONDULIN DIY” and “ONDULIN SMART”. The fundamental difference between them is only in the geometric dimensions of the sheet, and the resulting differences in weight and cost.

To simplify the perception of information about the physical, technical and operational characteristics of both types of ondulin, we will place it in the table:

Main characteristics of ondulin	"ONDULIN DIY"	"ONDULIN SMART"

An interesting feature - in comparison with previously produced types of ondulin, the "ONDULIN DIY" and "ONDULIN SMART" models - a lot easier to install and more profitable regarding quantity purchased sheets. All this is thanks to so-called “smart lock” and already marked lines and points for driving fastening nails.

In the illustration above, this smart lock is shown with thick lines, and in the upper left corner is a cross-section of this connection. These are two parallel grooves 15 mm wide, convex upward, which run along the upper and lower edges of the sheet at a distance of 20 mm from them, and at a distance of 50 mm from each other.

This improvement allows you to accurately combine adjacent sheets in one row (exactly along one line), without fear of getting an uneven eaves overhang or a broken line in the rows of roofing.

Another plus is that such profile grooves provide reliable vertical overlap of sheets (with this combination, the required overlap width of 120 mm is ensured). True, these 120 mm are only for slopes with a steepness of more than 15 degrees, but these are the angles that are most common in private residential construction.

Thanks to this innovation, it was possible to reduce the minimum overlap of sheets along the slope line by as much as 50 mm. In old ondulin models this figure was 170 mm, in the “SMART” and “DIY” models it was only 120 mm. The roof becomes lighter as less material is required.

Advantages and disadvantages of ondulin

To finish with the theory and move on to practical issues, it is also worth mentioning the “pros” and “cons” of ondulin - you need to know this even before deciding to choose this material as a roofing covering.

So to merits ondulin include the following:

• Unlike ondulin, which is similar in form and principles, it does not contain substances harmful to human health and the environment, in particular asbestos.
• The material is lightweight - which simplifies and reduces the cost of transportation, reduces the load on the rafter system, and significantly facilitates installation work.

• The small specific gravity of the material allows it to be laid generally over the old coating, without dismantling - just on top old roof perform the necessary sheathing.

• When installed correctly, such a roof provides guaranteed protection against leaks.
• Ondulin has a certain flexibility, which makes it possible to use it on problem areas of the roof where a small bending radius is required.
• Cellulose-bitumen sheets are hydrophobic and are not subject to corrosion or rotting.
• Due to its plasticity and elasticity, ondulin is not afraid of moderate pinpoint impacts, never cracks or chips when cutting or driving a nail, and can be easily cut without the use of any special tools.
• Coverage at correct installation able to withstand very significant snow and wind loads.
• Roofing made of ondulin perfectly dampens the noise of rain or hail, differing favorably in this regard from both slate and metal coverings.

• Installation of such a covering is very simple, and probably any good home owner can carry it out without resorting to the services of roofers.
• The buyer has a choice of several colors for the roofing covering - you can choose the one that is most harmonious with the planned exterior decoration of the entire building.

• If we add to all that has been said, very affordable price, then the popularity of ondulin becomes easily explained.

All this is wonderful, but we must not lose sight of certain flaws such roofing.

• Over time, ondulin fades in the sun, losing its original color, becoming dull.
• The material is classified as flammable. True, spontaneous combustion, for example, from sparks from a chimney or from overheating, is practically excluded, but in the event of a fire it will support combustion. According to many firefighters, this sometimes even speaks in favor of the coating - the faster the fire breaks out through the roof, the greater the chance of saving the main building.

• The material is quite durable, but still strong shock loads contraindicated for him. For example, it is easy to break it or crush it until it loses its tightness with a hammer blow during careless installation. But these are out of the ordinary cases.
• The rough surface of the material retains snow even at fairly large slope angles. But again, it remains to be seen whether this is considered a disadvantage or an advantage. If the rafter system and sheathing are planned and installed correctly, taking into account the likely snow load for the region of residence, then there is no harm in this.
• Some blame ondulin for its fragility. However, a 15-year factory warranty on branded material in itself speaks volumes. According to the manufacturer, the coating can last much longer (of course, in the absence of any force majeure circumstances).

So, based on the totality of characteristics, advantages and disadvantages, we can conclude that ondulin can be considered as, say, a budget-friendly, but still reliable and outwardly attractive roofing covering. And the ease of installation, which will be discussed below, also further conceals its shortcomings.

Self-installation of ondulin roofing

Roofing work is always preceded by the selection of material and the acquisition of the required quantity. What needs to be remembered in our case?

We have to state one sad pattern - only one or another construction material gains “authority”, and immediately counterfeits for it appear on the market, and, quite often – of very low quality. And ondulin is no exception in this series.

The cost of the original ondulin is not so high that you can look for it “for pennies.” It is best to start from the old folk wisdom that a miser pays twice. Under the collective name “Euro slate” there are already quite a few materials on sale, both more or less acceptable in quality and some not so good. And sellers often pass them off as real ondulin, or at least begin to convince them that this is a complete analogue, produced under license. Moreover, there are cases where unscrupulous store employees “sold” an unscrupulous consumer not roofing material at all, but cardboard-bitumen sheets intended for repair work and for creating additional under-roof waterproofing.

Therefore, if you decide to cover the roof of a house with ondulin, then you should always keep in mind several “axioms”:

• The Onduline company has never transferred licenses to anyone, and has not officially allowed other companies to produce analogues of its products. The management of the concern extremely values ​​​​the reputation of the brand, carries out the most stringent quality control, and no matter where the branded roofing covering is produced (including in Russia), it still appears under a single brand.
• Ondulin is sold only through a network of sales offices and official dealers with whom appropriate agreements have been concluded. It would be useful to clarify whether the seller has a standard certificate. If not, then this should give rise to some thoughts.

• It was already mentioned above that the manufacturer gives a very impressive guarantee for its products - 15 years. And this, in turn, means that no matter what batch of ondulin was not purchased, it must be accompanied by the appropriate passport. By the way, this document always contains clear step-by-step instructions for carrying out self-installation roofs. And at the very end of the passport there is a guarantee card, which sets out in detail all the provisions for providing a guarantee, and on which mandatory The date of sale must be endorsed with the signature and seal of the seller.

And a couple more useful tips.

• When purchasing, try to check that all sheets purchased are from the same factory batch. The fact is that the color in different batches may vary slightly in tone. It’s difficult to visually identify this in a store, but on the roof the transition of rhinestone tones becomes noticeable.
• Do not forget to check the condition of the sheets, especially if they are sold individually, in already unpacked form. Special attention– corners, since they most often “suffer” during careless transportation.

How much material will be needed?

We've sorted out the quality, now let's move on to the quantity of material.

Calculating the required number of ondulin sheets is not difficult: you need to find out the area of ​​the roof and divide it by the amount of the “useful” area of ​​the sheet, that is, without taking into account the side and end overlaps with neighboring sheets.

As can be seen from the table above, the amount of “useful” sheet area depends not only on its type - “SMART” or “DIY”, but also on the slope angle. This is explained simply - the flatter the slope, the slower the water drains from the roof, the greater the likelihood of it penetrating into the cracks between the sheets during, for example, strong winds, and the more overlaps are made to avoid leaks. We will get acquainted with specific standards for overlaps a little later, when we talk about the practice of installing the coating.

If this is an ordinary single- or gable roof, there are no problems - even a primary school student will determine the area of ​​the rectangle. It is somewhat more difficult with hip, hip, or multi-gable roofs. But even here it is quite possible to find a solution, and in some ways we can help.

Some useful calculators for calculating roof areas

On the pages of our portal there is a selection of calculators that greatly simplify the processes of calculating roof areas. So, the reader can use the calculation program; there is a separate calculator for determining. If the roof does not have a completely standard configuration, then it is better to divide it into sections of a simpler shape, and then each one, followed by summation.

Well, since the area of ​​the roof is known, all that remains is to divide it by the area of ​​the sheet. But it is also necessary to take into account that a certain part of the material will be cut, especially if the slopes have a trapezoidal or triangular shape. In addition, there is a possibility of accidental defects at work. That is, in order to insure against accidents, it is advisable to lay down a certain reserve, say, 10 percent.

You must immediately purchase the required number of nails. They must also be original - amateur performances are unacceptable here. The nails have a strictly defined length, guaranteeing reliable fastening of the ondulin sheets through the top of the wave. The nail heads are equipped with a special press washer and a sealing gasket. The color of the cap is selected depending on the chosen color of the coating - the fastener becomes very unnoticeable against the general background.

By the way, it makes sense to purchase new “Onduline” nails. If on previously produced nails, after hammering, the head was necessarily closed with a decorative cap, then on the latest samples the head is cast, not deformed by hammer blows. A trifle, of course, but on the scale of the entire roofing covering it seriously simplifies and speeds up installation.

When calculating the number of nails, we proceed from the fact that “Ondulin SMART” requires 20 nails per sheet, for “Ondulin DIY” - 15, since the sheets have two fewer waves.

It would probably be useful to take into account the fact that progress work, the nail may bend, that is, become unusable further use. In addition, it happens that when working at height, a master will drop one or two nails, and then they will not be immediately found. That is, it is necessary to lay down a reserve here too - in addition to the calculated number, based on the number of sheets required for the roof, purchase an additional couple of dozen nails - just in case. Even if they remain, there will always be a use for high-quality nails in the household.

To make it easier for the reader to calculate the required amount of materials, a calculator is provided below. The principle of working with it has already been outlined above, and probably no additional explanation is required.

Roofing material such as ondulin is gaining popularity faster and faster today. Unfortunately, not all developers are sufficiently aware of all its advantages and some disadvantages; few of them can boast of knowledge about its correct installation.

The modern market for roofing materials offers a fairly wide range of products, among which both the well-known slate and galvanization, as well as relatively new coatings, which only recently began to enter wide production, but are distinguished by a much more attractive ratio of price, quality and appearance, are famous.

After all, the functions of the roofing material should include not only protecting the structure from wind or precipitation, but also giving the entire structure a unique, original appearance that makes this or that house stand out from the rest.

The material is made from cellulose or fiberglass impregnated with bitumen, which are painted in different colors (more details: " "). Next, we will talk about how to properly cover a roof with ondulin, as well as the work skills and tools necessary for this process.

Ondulin material, also called Euroslate, is very reliable, despite its lightness and cost-effectiveness. Unlike, for example, Finnish metal tiles, when it rains, ondulin does not produce any sounds ( useful article: " "). It has been produced for about 50 years both in Russia and in foreign countries, and its cost varies depending on one manufacturer or another.

Standards for laying ondulin on the roof

Covering the roof with ondulin is a process that does not require special skills or tools specially designed for this. If the owner of the house has some knowledge, you can do this work yourself.

When wondering how to lay ondulin, you should remember that installation can be done in the same way as laying standard slate. The only difference is that, due to the ability of ondulin to bend significantly, its installation can be carried out not only on ordinary flat surfaces, but also on surfaces with a more complex configuration.

At the moment when we cover the roof with ondulin, which is laid on top of the old roofing covering (roofing felt, slate, metal, etc.), the assessment of the rafter system can be carried out either personally or by a specially invited roofing team.

If the assessment results show that the rafter system can withstand the additional weight of the new roofing, then a sheathing is made of wood onto the old roofing, onto which ondulin sheets are attached. This will provide additional thermal and waterproofing.

Since ondulin has relatively low rigidity, the lathing step should be frequent so that the sheets do not break or sag under the influence external loads in the form of rain or snow. You can saw ondulin using an electric jigsaw or a regular wood hacksaw, which must be lubricated in advance to avoid the hacksaw blade getting stuck and to simplify the entire sawing process.

Instructions for installing ondulin on the roof

As mentioned above, the process on the roof is similar to laying conventional asbestos-cement slate.

It is important to remember that you must always strictly follow all the points in the instructions that are attached to the finished material. This will help you better understand how to cover a roof with ondulin, without making significant or minor mistakes. Typically, these instructions are written quite clearly, and understanding them will not be difficult, even if your knowledge of the upcoming installation process is not so extensive.

Basic rules for laying ondulin on the roof:

1. Initially, you need to install a continuous sheathing made of wood. In this case, factors such as roof slope and wind direction in a particular area must be taken into account. It is best to start work from where the wind influence is least.
2. The distance at which the beams used to create the sheathing should be located from each other should be the same and equal to approximately 60 - 80 centimeters.
3. If the distances are large, then it is necessary to install additional slats, which should be located between the beams. This will provide the structure with additional strength. The angle of the roof slope must be at least 20 degrees.
4. It is better to start laying the material from the lower roof corner, and it is recommended to cut the first sheet in the second row longitudinally into two halves.
5. Ondulin sheets are fastened horizontally using special nails supplied with the material. 20 such nails should be used per sheet.
6. In the first of the rows of covering, every wave crest is nailed, in the remaining rows - every second.
7. It is important to remember the overlap when laying the second row. To do this, grab the sheet laid in the first row, then follow the same pattern. equipped with special rubber caps, the color of which is identical to the color of the coating. To make the surface of the coating look more attractive, it is recommended to nail these nails with colored heads at the same line level. This can be achieved by pulling a rope along which the nails will be driven.
8. Ondulin sheets should be nailed vertically to the sheathing beams (more details: " "). The transverse overlap should be equal to 15 centimeters, and the longitudinal overlap should be no less than the length of the first wave.
9. At the end of the installation of the overlapping covering, ridge elements are installed, which must be nailed along the wave of the ondulin sheet.
10. If the roof on which the installation is being carried out is gable, then special corner parts should be used to install the ridge. The roof valley is made using additional sheathing.

Typically, the instructions attached to the finished material include not only the rules and regulations for laying the coating, but also detailed drawings that enable anyone to understand the entire process in detail, regardless of their professional skills and knowledge.

If you strictly follow all the requirements described above for installing ondulin on the roof, then this roofing covering is guaranteed to last more than 50 years (the first 15 years are guaranteed by the manufacturer). The guarantee also includes a certificate of hygiene and fire safety.

Additional covering elements

In addition to the ondulin itself as a roof covering, manufacturers also offer a lot of additional elements provided for it, which are made of the same material.

These include the following:

• ridge element;
• endova for ondulin;
• tong parts;
• nails;
• self-adhesive sealant tape;
• cornice filler;
• ventilation tube;
• apron covering.

In order for the roofing covering to look attractive and harmonious, as well as to achieve its greatest efficiency, all accessories used during installation must be original, that is, they must be supplied together with the covering material. Read also: "

But first, let's take a closer look at the important information about ondulin, its disadvantages and advantages, and then we will discuss its installation on the roof, applying the knowledge gained.

What is ondulin?

Interestingly, the word “ondulin” rightfully refers to the products of Onduline SA. She was the developer of this material. But now we are accustomed to calling any roofing material made from bitumen-cellulose sheets ondulin. Some even began to use this name to refer to all types of roofing materials, especially flexible ones. For example, you can often hear builders talking about transparent ondulin.

In the production of real ondulin, the following components are used:

• cellulose base;
• bitumen;
• mineral filler;
• hardener resin;
• dye.

Under pressure and at high temperature, the cellulose base is impregnated with bitumen. After adding plasticizer and other fillers, we get waterproof ondulin. The water resistance of the material is achieved due to the special arrangement of cellulose fibers. Therefore, ondulin has a beneficial effect on the waterproofing characteristics of the house.

After passing through the above stages, ondulin is shaped in a molding machine. On modern market a wide variety of ondulin profiles can be found.

What are the advantages and disadvantages of ondulin?

Nowadays, laying ondulin on the roof has gained enormous popularity, especially in private homes and country houses. But the issue of choosing a roofing material must always be approached responsibly, so let’s pay attention to the positive aspects of using ondulin, and then we will discuss the negative aspects.

Advantages. The main advantages lie mostly in technical characteristics:

1. Excellent waterproofing . As we already mentioned, the special arrangement of cellulose fibers prevents the penetration of water. In addition, ondulin will not swell after prolonged rains and downpours; its waterproofing properties will remain unchanged in any case. And low hygroscopicity - the ability to absorb moisture from the air - makes this roofing material indispensable in areas with high rainfall.
2. Resistance to temperature changes . In both heat and cold, ondulin perfectly retains its abilities and does not deform.
3. Biological and chemical inertness . Roofing made of ondulin is not susceptible to the influence of fungi and other bacteria, which reduce. And chemical inertness allows you to maintain stability when exposed to alkalis, acids, oils or anything else.
4. Low weight of the final product . Perhaps weight is one of the key points in the coating, as well as, which makes it possible to facilitate the entire process of roof installation. Also, less weight creates less load on the building frame, due to which the beams wear out and deteriorate more slowly (more about).

Flaws . Yes, it doesn't happen ideal materials, and ondulin is no exception. So let's look at some of the main disadvantages.

Despite all the claims of Onduline SA, its product ultimately still fades in the sun, becoming paler. Therefore, if the color of the roof is of paramount importance to you, then be sure to take this point into account. Although it is possible to preserve the original color of the roof to some extent: use paint. The most suitable paints were VD-AK-101 or “VAKSA”, most of which were developed specifically for painting roofing materials.

Laying ondulin: instructions

If you still choose ondulin as a coating, then before roofing work some preparation is needed.

Despite the fact that the technology for laying ondulin is relatively simple, it is important to consider the following features:

Fixing ondulin on the roof

So, we have prepared the sheathing and are ready for further work. It's time to learn how to properly install ondulin.

To begin with, we simply lay it on the sheathing using special fasteners. After this, it is necessary to carefully align the sheets vertically and horizontally.

Further installation is carried out according to the following algorithm:

• Be sure to lay the ondulin staggered; the joints of the sheets should not converge.
• You need to start laying from the edge opposite to the dominant winds in the area. This will allow the coating to more resistantly withstand gusty and sharp winds. In all other cases, ondulin can easily fall off the roof (read: "").
• The length of the overlap depends on the roof slope. The overlap varies in proportion to the roof slope. The smaller the slope, the more overlap you make. The maximum overlap - 2 waves wide and 30 cm high - is used on roofs with a slope angle of up to 10 degrees. If the slope is more than 15 degrees, then an overlap of one wave horizontally and 15 cm vertically is sufficient.
• You need to nail ondulin with special nails at the bottom on each wave, and in the middle and at the top - every other wave, so that these two lines of nails form a zigzag. Nails must be nailed on the same line both vertically and horizontally. To do this, we stretch some cord, fishing line or thread, and then navigate along them.

• We attach the gutters of the drainage system to the eaves board. The sheets of laid ondulin should protrude slightly beyond the cornice board, but at the same time maximum protrusion is 70 mm. It is advisable to install a special eaves grille under the cornice to protect against insects and birds.
• We attach the ridge element to each wave and directly to the sheathing. We build up the ridge elements by laying them with an overlap of at least 120 mm.
• We use special ones to protect ondulin. They need to be attached to the gables in such a way that the area where the ondulin joins the roof is completely covered by these elements.

As you can see, there should not be any particular difficulties with this technique. To master it even better, we recommend watching photo and video materials of the installation of ondulin roofing. And if you can perfectly master the technology of laying ondulin, then the completed roof will delight your family for years, or even decades!

Ondulin, or, as it is also called, Euroslate, is not new to the building materials market. Over more than half a century of history, it has established itself as a strong and durable roofing covering. The popularity of ondulin flooring is explained by both its affordable cost and operational benefits, and ease of installation. It is the last factor that often plays a decisive role in private construction, when you need to build a roof with your own hands. Today we will look at the features of Euro slate and talk about how to use it to create a dry and reliable roof.

Characteristics of roofing material, its advantages and disadvantages

Ondulin looks very similar to classic slate and is the same flat sheets with a wavy surface. If we consider the structure and manufacturing technology, then this roofing material is much closer to roofing felt - a cardboard base and bitumen impregnation are also used for its production.

Ondulin is combined with ordinary slate only appearance and similar installation technology

Thoroughly purified cellulose fibers are dyed in the mass and pressed, obtaining blanks of the desired length and shape. After this, the sheets are impregnated with a bitumen mixture, while simultaneously being exposed to high pressure and temperature. This not only speeds up the process, but also makes it more uniform. To make the material both durable and elastic, fiberglass, synthetic resins and mineral fillers are added to the impregnation. This technology makes it possible to obtain a roofing covering that differs:

• high resistance to low and high temperatures, as well as their sudden changes;
• minimal water absorption;
• resistance to bacterial and fungal contamination, as well as chemical reagents;
• long service life - although manufacturers give 15–20 years of warranty for roofing material, individual ondulin roofs have been regularly performing their functions since the 50s of the last century;
• light weight - a sheet of Euro slate weighs only 6 kg, which greatly facilitates the installation of the material and its transportation;
• simplified installation technology, which allows you to cover the roof with your own hands, without the involvement of specialists and expensive equipment;
• flexibility, which is important when arranging complex roofs with multi-slope slopes, valleys, external corners, skylights etc.;
• affordable cost - although ondulin is 30–40% more expensive than traditional slate, this difference is offset by savings in lumber for the roofing frame and transportation costs.

And yet, when choosing ondulin as a roofing covering, we should not forget that it was developed as a temporary material for quick repairs and restoration of damaged roofs in post-war period. Of course, Euro slate has much fewer disadvantages than advantages, but they must be taken into account both during design and installation, and during operation.

Installation errors often lead to deformation of the ondulin, so you should not neglect the rules for its installation

It should be remembered that ondulin does not tolerate careless treatment of the wooden frame. Due to the sheathing being too thin or not rigid enough, the sheets may bend over time and the roof will begin to leak. In addition, walking on such flooring will be unsafe. Due to the peculiarities of production, this type of roofing is presented in only four colors - green, black, red, brown and their shades, so there is no need to talk about any color variety. In addition, cellulose impregnated with bitumen has a tendency to fade in the sun, and in poorly lit places it quickly becomes overgrown with moss. However, with proper care, such troubles can be avoided.

Roof installation for ondulin

When constructing roofs with ondulin flooring, almost the same frame is used as for slate roofing. The only difference is that lighter euro slate does not require additional structural reinforcement.

A standard ondulin roof consists of several components:

1. Wooden frame. The basis of the structure are rafters, which are made of wooden beam with a section from 80x80 mm to 150x150 mm or boards 50–60 mm thick and 120–150 mm wide, mounted on edge.
2. Thermal insulation. When constructing roofs for residential buildings, a warm roofing cake is created. Fibrous materials such as basalt or glass wool, as well as slab insulation made of extruded polystyrene foam, are most often used as insulation.
3. Vapor barrier. When using fiber thermal insulation, a vapor barrier membrane is required, which protects the insulation from getting wet.
4. Waterproofing layer. To protect the wooden frame and insulation from possible leaks and drops of condensation, a polymer film is laid on it. It is mounted on top of the thermal insulation and secured to the rafters with a construction stapler.
5. Countergrid. This structural element is needed in order to organize a ventilation gap between the lower and upper layers of the roofing cake. Without a counter beam, the movement of air in the under-roof space will be difficult, which can lead to wetting and damage to the insulation. The counterbeam is nailed along the rafter legs, simultaneously fixing the waterproofing with it.
6. Lathing. Depending on the slope of the roof slope, a sparse base made of unedged boards or a solid flooring made of OSB or moisture-resistant plywood can be used under the ondulin.
7. Euroslate. The material is laid with an overlap in one wave, and fastening to wooden sheathing performed with special nails with wide heads.

Of course, if it is necessary to cover the roof of some undemanding outbuilding, then the design of the roofing pie is significantly simplified. In this case, insulation, vapor barrier membrane and counter beam are not used. As for waterproofing, you shouldn’t give it up. A layer of polymer film or roofing felt can be installed on top of the sheathing - so wooden structures will be maximally protected from moisture and snow blowing.

The design of the roofing pie of an ondulin roof has much in common with the design of both soft and slate roofs

When starting to install the wooden elements of the rafter system and roofing pie, do not forget to treat the lumber with an antiseptic with insecticidal protection and a fire retardant. This will increase the structure’s resistance to fire and prevent wood from being damaged by fungi and insects.

What materials and tools will be needed for work?

When starting to build a roof with ondulin coating, you should prepare:

1. Ondulin sheets. Considering that they have standard dimensions of 200x95 cm, it will not be difficult to calculate how much material will be needed. Later we will return to the method of determining exact quantity Euro slate, taking into account trimming and joining.
2. Beam with a cross-section of at least 40x40 mm for the construction of a counter-lattice.
3. Boards to build sparse sheathing or plywood (OSB), which will be needed to make a solid base.
4. Nails for constructing sheathing and fastening ondulin.
5. Cornice strips, or, according to the manufacturer’s classification, an edge gong (in common parlance “chip”), which is needed to protect the edge wooden base from dripping moisture.
6. Valleys, which will be needed for arranging the joints of adjacent roof slopes.
7. Ridge elements. Like other additional parts, Ondulin special corner molding has the same structure, color and specifications, as roofing sheets. To protect the gap between the ridge and the roofing sheet from snow and debris, a universal ventilated infill is used. By the way, the latter is also used on the cornice, closing the gap between the Euro slate and the outer board of the sheathing.
8. Tape insulation to protect the passage of utility lines and junctions with vertical walls, as well as rubber aprons for waterproofing round chimneys and ventilation ducts.

In addition, depending on the type of roof (cold or warm), it is necessary to stock up on roll or slab thermal insulation, a vapor barrier membrane, as well as a waterproofing film or roofing felt.

When choosing additional elements, you should focus on the color of the main coating - the tone of materials from different manufacturers may differ significantly

We have already said above that when installing ondulin you do not need any special tool. Here is a complete list of what may be required during the work process:

• wood hacksaw with medium or fine teeth;
• carpenter's hammer with a forked shank;
• Phillips screwdriver;
• construction stapler equipped with staples for fastening film materials;
• cutting knife with replaceable blades;
• roulette;
• marker or pencil;
• cord;
• chalk or graphite powder.

It should be remembered that using a power tool will significantly reduce the execution time. construction work. If possible, the hacksaw can be replaced with a hand-held circular saw or electric jigsaw, and a screwdriver - a screwdriver with a suitable set of bits.

How much ondulin will be needed: calculation method

• draw up a roof drawing indicating exact dimensions and locations of additional elements;
• break down the roof plan into simple geometric shapes;
• find the area of ​​all parts and perform addition;
• multiply the amount by a correction factor of 1.2;
• divide the calculation result by the effective area of ​​one sheet.

Although the square footage of a standard Euro slate sheet is 2 x 0.95 = 1.9 square meters. m, in fact the effective area is no more than 1.6 square meters. m. This is due to the fact that during installation, part of the roofing material is covered by adjacent sheets.

A detailed roof plan not only simplifies the design process, but also allows you to perform calculations with the required accuracy

To check the correctness of the calculations, the total area of ​​all roof slopes must be divided by the useful quadrature and a margin for trimming and joining the material must be added to the result obtained. Depending on the type of roof, the amendment can range from 10–15% for simple gable and hip structures up to 15–20% if the roof has complex geometry:

• for slopes with a slope of up to 10 o, the longitudinal overlap should be at least 30 cm, and the lateral overlap should be two waves. In this case, the material consumption is adjusted according to the upper value of the fork;
• for roofs with a slope of more than 15 o, an overlap of 15–20 cm and a transverse overlap of one wave is sufficient. Less material will be needed, so a minimum supply within the above limits is taken.

When determining the molding of additional elements, it is necessary to take into account both their standard length and the width of the overlap. Usually, at the junctions of ridge, chip and valley elements, a 15-centimeter overlap of adjacent parts is quite sufficient.

How to fasten euro slate: which roofing nails are suitable and how many of them are needed

To install ondulin, special nails with a wide head and a curved washer are used - thanks to them, reliable fastening is achieved and a tight fit to the tops of the waves. On sale you can find two types of fasteners - with a monolithic head and with a cap that covers the metal head of the nail. Both can be made from polyvinyl chloride or polypropylene. These materials have sufficient elasticity to protect the mounting points from leaks, and in addition, they are resistant to sunlight and are not susceptible to atmospheric factors.

To fasten ondulin, special nails with wide heads made of high-quality plastic are used

Manufacturers produce nails in the same shades as the main coating, so you can always choose fasteners to match the roof. Their rod is made of galvanized steel and has a length of 70–75 mm with a standard diameter of 3.55 mm, thanks to which the metal part reliably fits into the sheathing to a depth of more than 10 mm.

Each sheet of Euro slate must be attached at 20 points, which allows for a fairly accurate calculation required number hardware However, the calculation does not end there - you should also determine the number of nails with which the valleys, skates and chips will be attached. Knowing the length of these sections, determine total number additional elements. The result obtained is multiplied by 6 (each of them is fastened at 6 points) and added to the previously obtained figure. By making a small adjustment for damage and loss of fasteners during operation, you can obtain the most accurate amount of their consumption.

How and with what to cut ondulin

Cardboard sheets impregnated with bitumen-polymer compositions are quite soft material, so to cut them you can use either a circular saw or a regular wood saw. The only difficulty is that the saw teeth very quickly become clogged with resin during operation.

Ondulin is quite easy to cut with a hand saw, so you can do without power tools

To avoid having to clean the tool from sticking bitumen after 1-2 cuts, experts recommend lubricating cutting part any mineral oil. If this method does not seem very aesthetic to you, then you can use another advice from experienced roofers - regularly moisten the hacksaw with cold water.

Euroslate roof staircase

Ondulin is a fairly durable and flexible material, but do not let this fool you. You should walk on the finished flooring as carefully as possible, stepping on the tops of the waves only in those places where the sheathing boards pass underneath. You can make moving on the roof safer with the help of a special pitched staircase and transition bridges. They will also be useful in the future - for roof inspections and routine repairs.

A roofing ladder will save time and nerves during installation and during roof maintenance

In construction stores, roofing ladders are presented in products made of steel, aluminum profiles and wood, but experts recommend making such devices yourself. Firstly, this will allow you to save a little, and secondly, homemade stairs and bridges will correspond to the characteristics of the roof slopes.

To build a pitched staircase you will need:

• boards 160x25 cm;
• bars with a section of 50x50 mm;
• nails.

Having cut the boards to the required length, they are laid on a flat surface. After this, crossbars are nailed in increments of 40–50 cm. At the top of the staircase, the ladder is equipped with a wooden “hook” made from pieces of boards and timber - with its help, the device can be hooked onto the ridge. When determining the parameters of the toe, be sure to take into account the steepness of the slopes, its own weight and the dimensions of the stairs. If you are interested in the minimum dimensions of the counter part, then experts advise making a hook at least 30 cm long.

Do-it-yourself roof covering with ondulin

The construction of an ondulin roof includes several stages:

• production of sheathing;
• laying roofing material;
• fastening of additional elements;
• arrangement of places for passage through the roof of ventilation and chimney pipes, utilities, etc.

In addition, when constructing warm roof It will be necessary to consider the ventilation of the under-roof space and install thermal insulation. We will consider the features of all these processes in detail.

Arrangement of sheathing

Due to the insufficient rigidity of ondulin, the sheathing for this roofing material must take into account the angle of inclination of the roof. Otherwise, during heavy snowfalls, the decking may bend and the roof will begin to leak.

The design of the roof sheathing made of rigid bitumen sheets must correspond to the slope of the roof slopes

There are three main ways to arrange a base for Euro slate:

• continuous sheathing made of shag boards, plywood or OSB sheets on slopes with a slope of less than 10 o;
• sparse lathing made of timber or boards 25 mm thick, located in increments of up to 45 cm - on a roof with a slope of 10–15 o;
• sparse sheathing made of unedged lumber or timber, installed at a distance of up to 60 cm from each other, if the slope has a steepness of more than 15 o.

Installation of the wooden base is carried out in the classic way. On cold-type roofs, timber or boards are nailed directly to the rafters, and when arranging an insulated roofing pie, a counter batten is used.

Step-by-step instructions for installing ondulin on the roof

Laying ondulin has much in common with installing slate flooring. The differences relate only to the fastening scheme of the sheets and some nuances of the arrangement of the base. It is best to carry out work at air temperatures from -5 to +30 °C, choosing clear, calm weather.

Having finished styling last row, begin to install additional elements. The construction of the roof is completed by arranging the places where pipes and communications pass through the flooring.

Ridge installation

To arrange the tops of the roof, special ridge elements measuring 100x36 cm are used, which are produced using the same technology as the main covering. When installing them, follow the following rules:

After installing the last panel, the gap between the ridge and the ondulin is closed with universal filler, and plugs are installed at the ends.

When arranging ridges hip roof It is necessary to leave allowances for ridge elements of 20–25 cm on each side. After installation, the protruding edges are heated with a construction hairdryer, straightened and attached to the sheathing.

Video: features of ridge installation

Attaching the pliers

When installing the gable element, adhere to the following scheme:

After the last tong is secured, its edge is cut flush with the ridge.

Installation of valleys

At the junction of adjacent slopes, an additional sheathing with a width of at least 25 cm from the center line is constructed. The valley is installed in the direction from the lower overhang to the ridge, releasing the starting element at a distance of 5–7 cm from the edge of the sheathing.

To fasten the valley elements, reinforced sheathing is used, otherwise the joint of adjacent slopes may suffer from snow load

As with the installation of other extensions, the overlap of adjacent panels should be at least 15 cm. The edges of the sheets are cut at a distance of 3–5 cm from the axis of the groove, after which they are fastened along all adjacent waves. In this case, nails must be driven no closer than 3 cm from the edge of the valley elements.

Video: design option for a valley roof made of ondulin

Arrangement of junctions and passages through the roof

The junctions of the roof with walls and other vertical elements are protected with a special covering apron. This additional element is a shortened sheet of ondulin with a flat wing located at right angles to the wavy surface. In addition, areas prone to leaks can be protected using Onduflesh self-adhesive tape, which provides reliable waterproofing.

The junctions with the walls are equipped with the help of special sealing aprons

If ventilation pipes and other utilities pass through the roof, then special insert elements are placed around them, which can be purchased simultaneously with the sheets for flooring. If this is not possible, you can use homemade aprons made of thick rubber or seal the joints with Onduflesh tape. In the case where a metal chimney passes through the roof, it is necessary to build a special passage box with thermal insulation or use a factory roof cut. For maximum protection against leaks, a non-flammable Master-Flash cuff is installed over the chimney.

In places where metal passes chimneys install special roofing trim

We should not forget that ondulin consists half of bitumen. For this reason it is prohibited to use metal pipes, if the temperature of the exhaust gases exceeds 500 °C, and also if coal is used to fire the furnace. In any case, the chimney must be equipped with a spark arrester.

Ventilation of the under-roof space

It should be noted that ondulin flooring is much less prone to condensation than soft roofing or metal roofing. However, if the roof structure provides for the installation of insulation, then ventilation of the under-roof space cannot be avoided.

Ventilation of the under-roof space is carried out due to counter beams and gaps between the ridge and the flooring

You can create a ventilation gap between the roofing material and the thermal insulation using a counter batten, which is attached along the rafter legs. The cross-section of the counter beam should be such as to provide a gap between the sparse sheathing and the waterproofing layer of at least 3–5 cm. As for the air outlet at the top of the slopes, it is provided by special ventilated profiles that are installed under the ridge elements.

Installation errors

Neglecting the technology and rules for laying ondulin, novice roofers often make the following mistakes:

1. The pitch of the sheathing does not correspond to the angle of inclination of the slopes.
2. The wooden frame at the valleys and ridges of the roof has not been reinforced.
3. The cross-section of the sheathing elements does not correspond to the snow load in this region.
4. The thickness of the counter beam is not enough for normal ventilation of the under-roof space.
5. Violation of the pattern of fastening sheets to the sheathing.
6. The absence of hydro- and vapor barrier layers when using a warm roofing cake.
7. Using regular nails.
8. Installation of sheets pre-loaded in the transverse direction (either tension or compression is prohibited).
9. Insufficient vertical or horizontal overlap.
10. Installation of rows without displacement, as a result of which junction points of four sheets appear.

Perhaps, having familiarized yourself with the most annoying mistakes, you will prevent them from happening in your work and thereby be able to avoid troubles both during installation and during the subsequent operation of the roof.

As you can see, there is nothing complicated about covering the roof with ondulin. You just need to follow the technology provided by the manufacturer and listen to the advice of experienced craftsmen. Only in this case can one hope not only for the absence of leaks and durability, but also for the fact that the roof will have a neat and attractive appearance. And this is also important, isn’t it?
