But first, let's take a closer look at 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. It was she who was the developer of this material. But now we are used to calling ondulin any roofing material made of bitumen-cellulose sheets. Some even began to use this name to refer to all types roofing materialespecially flexible. 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;
- resin hardener;
- dye.
Under pressure and at high temperatures, the cellulosic base is impregnated with bitumen. After adding plasticizer and other fillers, we get waterproof ondulin. The waterproofness 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 going through the above steps, the ondulin is shaped in a molding machine. On the modern market, you can find a wide variety of ondulin profiles.
What are the advantages and disadvantages of ondulin?
Nowadays, laying ondulin on the roof has gained immense popularity, especially in private houses and in summer cottages. But the question of choosing a roofing material always needs to be approached responsibly, therefore, we will pay attention to the positive aspects of using ondulin, and then we will discuss the negative aspects.
Benefits. The main advantages are mostly in technical characteristics:
- Excellent waterproofing ... As we have already mentioned, the special arrangement of the cellulose fibers prevents water penetration. In addition, ondulin will not swell after prolonged rains and downpours, it waterproofing properties will be 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.
- Resistant to temperature changes ... Both in the heat and in the cold, ondulin perfectly retains its abilities and does not deform.
- Biological and chemical inertness ... Ondulin roofing is not affected by fungi and other bacteria that reduce. And chemical inertness allows it to remain stable when exposed to alkalis, acids, oils or something else.
- 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 installing the roof. Also, less weight creates less stress on the building frame, due to which the beams wear out and deteriorate more slowly (more about).
disadvantages ... Yes, there are no perfect materials, and ondulin is no exception. Therefore, let's look at some of the main disadvantages.
Despite all Onduline SA's claims, its product will eventually fade in the sun, becoming paler. Therefore, if the color of the roof is of paramount importance to you, then be sure to consider this point. Although it is possible to preserve the original color of the roof to some extent: use paint. The most suitable were the VD-AK-101 or VAKSA paints, most of which were developed specifically for painting roofing materials.
Both shortcomings are not so critical as to instantly abandon the prospect of using ondulin in their home, so many make their choice in favor of it. Now it's time to find out how the ondulin laying with your own hands is going on (a similar article: "Do-it-yourself ondulin installation - features of the technique
Further installation is carried out according to the following algorithm:
- We lay the ondulin in a ragged way, the joints of the sheets should not converge.
- You need to start laying from the edge opposite to the prevailing winds in the area. This will allow the coating to withstand gusty and harsh winds more firmly. In all other cases, ondulin can easily fall off the roof (read: "Do-it-yourself roofing with ondulin").
- The length of the overlap depends on the roof slope. The overlap changes in proportion to the roof slope. The smaller the slope, the more overlap. The maximum overlap - 2 waves wide and 30 cm high - is used on roofs with an inclination 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 enough.
- You need to nail ondulin with special nails at the bottom of each wave, and in the middle and at the top - through one, so that these two lines of nails form a zigzag. You need to nail the nails in one line both vertically and horizontally. To do this, we pull on some kind of cord, fishing line or thread, and then we orient ourselves along them.
Is ondulin burning, see the video for more details:
- Gutters drainage system we attach to the cornice board. The sheets of the laid ondulin should protrude slightly beyond the cornice board, but the maximum protrusion is 70 mm. It is advisable to install a special cornice lattice under the cornice to protect it from insects and birds.
- We attach the ridge element to each wave and directly to the crate. We build up the ridge elements, laying them with an overlap of at least 120 mm.
- We use special ones to protect the ondulin. It is necessary to fasten them to the gables in such a way that the junction of the ondulin to the roof is completely covered by these elements.
As you can see, there should be no special difficulties with this technique. To master it even better, we advise you to look at the photo and video materials of the installation of the ondulin roof. And if you can perfectly master the technology of laying ondulin, then the made roof will delight your family for more than one year, or even more than one decade!
Which can be mounted in different ways, depending on the purpose of the roof.
The layers of the roof that you need to cover the roof are called roofing pie. Each of the layers of the roofing cake performs its functions and is laid in accordance with certain rules. If the laying of at least one layer of the roofing cake is violated, the principle of the functional purpose of the entire roof is completely violated.
Depending on the structure of the roof, on its purpose, the sequence, method of installation and the number of layers may differ slightly. In this article, you will learn how to put ondulin correctly and how to calculate the number of roofing sheets.
The width and length of a standard sheet of euro slate is 95 cm and 200 cm, respectively. The area of \u200b\u200bsuch a sheet is 1.92 square meters. The useful area of \u200b\u200bthe material is determined without overlaps and can be: 1.3 sq. m, 1.5 sq. m and 1.6 sq. m.
To calculate the consumption of material, indicators should be determined:
- useful area of \u200b\u200bthe covering material. Depends on the angle of inclination. The multi-slope shape of the roof is calculated from the totality of the areas of each of the slopes;
- roof area. It is determined by adding the areas of all slopes by mathematical formulas of figures (trapezoid, square, rectangle, triangle);
- number of sheets of material. It is determined by dividing the area of \u200b\u200bthe entire roof by the usable area of \u200b\u200bone sheet of material.
CAUTION!
The roof area is calculated solely along the eaves overhang, but not along the edge of the roof sheathing.
Correct calculation of longitudinal overlaps is essential, which can significantly reduce the number of trimmings. The top row, if possible, should be laid in sheets of full length, since its height will be reduced by the ridge element.
There are a few more additions to correct calculation ondulina:
- when calculating, add 10% or 15-20% additionally respectively, to a simple roof or a complex roof with different angles and transitions;
- additional elements (ridge, valleys, tongs, aprons around chimneys and windows, junction points) require additional coverage with ondulin;
- when calculating an ondulin of a mixed color scheme, you should schematically depict the design of the roof on a reduced scale and calculate the consumption of sheets of each color separately.
Special programs for calculating the consumption of covering material greatly facilitate mathematical calculations and help to more accurately calculate the amount of Euro slate for roofing.
Ondulin - installation instructions
When the lathing is mounted in accordance with the angle of inclination, the covering should be laid in stages. Installation of ondulin step by step:
ondulin (tile) installation instructions
Now you know in detail how to put ondulin. All stages of roofing provide an error-free installation of ondulin, regardless of what kind of roof design is provided. The sequence of actions ensures a good result.
Waterproofing and vapor barrier for ondulin
Firms that produce ondulin present the material as a coating that does not require the installation of additional vapor barrier materials or waterproofing. At the same time, it is recommended to equip the roof of the room (or attic) requiring insulation with a waterproofing layer. We also recommend installing a vapor barrier from the room side.
Additional waterproofing elements and ventilation devices:
- waterproofing of the roof cornice is provided with a special box, which is attached to the base of the sheet overhang;
- ventilation is provided by ventilation pipes, which, like the window, are fastened with self-tapping screws for each wave of the coating;
- to protect against insects, a ventilation comb is mounted in the gap under the eaves;
- the joints of ondulin canvases are glued with a tape produced by the manufacturer of the coating (Onduflesh);
- joints of windows, valleys and other joints with the roof, cornices are also glued with adhesive tape;

Conclusion
It is possible to cover the roof with ondulin quite efficiently if you study the principles of operation and take into account the nuances of installation. Despite the fact that the material is quite light, one person will be able to install it.
In contact with
Strong, lightweight and durable material on a bitumen-polymer basis - ondulin, will last a very long time and create reliable protection at home if you complete the installation correctly. It can be laid on any type of roof - from the simplest to the most complex. The natural ingredients in the composition are completely harmless to health and the environment. Having learned a little more about how to lay ondulin, you will easily and quickly cope with the task yourself.
Since ondulin is a very durable and lightweight material (sheet weight is only about 6 kg), transportation and installation is extremely easy. There is no need to be afraid that the sheets will be scratched or broken from accidental impacts.
Ondulin characteristics
Many are interested in the question - how does ondulin look like, and what is included in its composition. And it is produced by the French company of the same name from cellulose impregnated with polymer substances and then coated with distilled bitumen. Special technologies for its production make the material very durable and resistant to various damages. Sheets with dimensions of 200 cm × 95 cm have a wavy surface, which gives them increased rigidity. The weight of one sheet is 6 kg, the wave height of the ondulin is 36 mm.
Note!
The profile in the form of waves not only allows water to drain quickly and evenly, but also dampens the noise from falling drops during rain.
Sheets are painted in varied colors, so there will be no problem in choosing the shade you need.
The material is very similar to ordinary asbestos-cement slate, with the only caveat - it looks more aesthetic.
Since the weight of ondulin is small, there is no need to make additional reinforcement rafter system... But, it should be borne in mind that when high temperatures the material softens slightly and may bend. Therefore, too rare a sheathing step is undesirable.
The order of further work looks like this:
- The lathing beams are nailed to the rafter system with a step corresponding to the slope angle of the ramp. To control the parallelism of the beams, it is convenient to use a piece of the bar, inserting it between each previous and each next sheathing beam.
- If necessary, before putting ondulin, you can cut the sheets into fragments of the desired size. This is done with a regular wood hacksaw, although a circular saw can also be used. To make the saw work easily, it is advisable to lubricate it with any oil.
- It is advisable, before putting ondulin correctly, to start installation by laying the first sheet from the edge opposite to the wind direction. In even rows, it is advisable to start with half the sheet.
- After pre-laying and leveling, ondulin can be nailed to the crate. Best suited for this are special nails designed specifically for this material. Each nail is equipped with a wide head and gasket to ensure a tight seal. Nails are required at the rate of 20 pieces per sheet. So that they enter the crate in a straight line, it is convenient to stretch the cord and hammer them along its line.
- Nails are driven in at the highest point of each wave. Along the transverse edges, ondulin is attached along each wave, in the middle - through one. Before working with ondulin, gutter holders are attached along the perimeter of the roof.
- After the sheets are nailed, the gutters of the gutters are attached to the cornice board. So that water does not overflow over the gutter, take into account when laying the ondulin so that the sheet is at the level of the gutter by no more than 5-7 cm.
- To further isolate the curtain rod from water, it is recommended to use a special curtain rod box. Sheets should also be found on it, no more than 7 cm.
- For ventilation and to prevent the entry of birds, insects and other animals, a special comb is installed under the cornice.
- For non-ventilated eaves, it is possible to use a filler for onduline roofs.
- Ridge protection is installed and nailed to each wave of the covering, under which additional battens are laid. The overlap of the ridge protection on the sheets must be at least 12 cm.
- Anyone who already knows how to properly cover with ondulin will take into account that the roof chip must be protected with a special chip element. There is another way - the edge of the covering sheet is folded onto a chipboard and nailed at intervals of 20-30 cm. But this method will work only if it is warm outside. Ondulin is quite plastic in warmth and fragile in the cold.
- In the places where the roof adjoins the wall, as well as where the chimney, windows or other elements come out, sealing aprons intended for this material must be made.
- All joints must be additionally insulated with a special tape or sealant.
- If it is necessary to get daylight under the roof, a special, translucent ondulin, which was described above, is mounted in the right places.
- A special fan can be attached to ventilate the roof. The roofing device is nailed to each wave. Make sure the top sheet overlaps the base of the appliance.
- An additional crate is made and the valleys are fixed.
- If it is necessary to lay ondulin on a rigid base (concrete, slabs), the lathing may be fastened directly to the base. Next, the coating is laid in exactly the same way as described above.
Ondulin is one of the most popular building materials, used for the roof of almost any roof, regardless of the complexity of their design. However, not everyone knows how to lay ondulin, and if they do, they do not take into account some of the features of working with this building material.
In this article, we will analyze this issue in as much detail as possible, but first I would like to talk about why ondulin gained such popularity, that is, about the technical characteristics and features.
Material features
Ondulin is a material that has been produced by the French company of the same name for more than 60 years, but in the CIS countries it gained fame only in the mid-nineties.
The basis of the material is cellulose fibers impregnated with bitumen under high pressure. In addition, during the production of ondulin, other mineral components are added to it. In some cases, the sheets are also painted.
The sheets are very dense, as well as strong enough (they are able to withstand a load of 200 kg per 1 square meter). Among other things, they are also lightweight, which allows one person to carry out installation work without attracting additional labor.
Another advantage of ondulin is its high sound insulation. This saves on soundproofing your roof.
Also, this building material is practically immune to the effects of natural factors, for example, to corrosion, or to the appearance of fungi. It is impossible not to mention environmental safety. The water that flows from the roof is often used in summer cottages for subsequent irrigation of crops.
Nevertheless, this building material also has drawbacks - it catches fire quite easily, which is why you have to take additional care of fire safety. In addition, in the bright sun, the paint on the roof can fade, but this drawback can be easily dealt with - for this you need to use a regular spray paint can.
Attention! Quite a lot of ondulin fakes have appeared on the construction market, so you need to choose it correctly. It is imperative to check all documentation for the batch, as well as to make sure that there are product quality certificates.
Ondulin's analogs
Due to the high popularity of euro slate (the second name of ondulin), more and more similar materials began to appear on the construction market, which we will talk about further.
- PVC ondulin 95. The material differs from the progenitor in that it is based on polymer rather than bitumen. This gives him the ability to let light into the house, which can be used to create natural light in the attic if converted into an attic.
- Nulin is a Euro-slate made in the USA. Its distinctive feature is the patented coating. In addition, only high quality raw materials are used in its production. Otherwise, these materials are almost the same, well, except that the weight of the sheets is slightly different.
- Ondura is another material that is a clone of ondulin. The difference here is in the richer palette of colors in which it is produced.
Before we start talking about how to lay ondulin correctly, I would like to give a few tips that must be taken into account during the work. By the way, everything that will be written below is true for all versions of the euro slate, including products from other manufacturers.
- First advice: it is better to cover the roof at a temperature of 10 to 20 degrees. The fact is that the material becomes very soft at high temperatures, and brittle at low temperatures. In either case, it is almost impossible to work with it, since the sheets will either bend or break.
- Second advice: it is better to move on the roof during work in shoes, and you should only step on those places where the crate is laid. This, again, will prevent damage to the euro slate.
- Third tip: for fixing the euro slate, it is better to use special nails, which, firstly, have waterproofing, and secondly, do not damage the material.
How to lay ondulin with your own hands?
So, now we come close to the answer to the question asked at the beginning of the article. Namely, how to lay ondulin on the roof.
Initially, you need to clarify the angle of the slope of your future roof. The step of the crate will depend on this.
Solid lathing is done if the slope angle does not exceed 10 degrees. In this case, the transverse overlap between the sheets will be equal to 30 cm, and the lateral overlap - two waves.
If the angle of the slope is from 10 to 15 degrees, then the step between the battens of the sheathing should be approximately 45 cm. The transverse overlap is 20 cm.
Well, if the slope angle of your roof is from 15 to 30 degrees, then it is better to do the lathing with a step of 60 cm. As for the transverse and side overlaps, here these values \u200b\u200bare identical to the previous option.
Important! Ondulin is light and soft material, therefore, additionally strengthen the rafter system, as well as other bearing structures roofs are optional.
Installation procedure
It is very important to remember that the roof will last a long time only if you fully followed the installation technology. Next, we will try to describe the whole process in as much detail as possible, but if something becomes unclear to you, then you can watch the video on how to lay ondulin on the roof, presented in this material... This video will help you familiarize yourself with this process in more detail.
- Step one: you need to nail the crate to the rafters, if you have not done this before. Remember the angle of the slope and the step between the bars - we talked about this a little higher. In order not to constantly measure the distance between the bars with a tape measure, we recommend making a special control bar, with which it will be easier to check the distance later.
- Step two: we cut sheets of roofing material if necessary. A hacksaw for wood is usually suitable for these purposes. In order not to bite the sheets, it is recommended to lubricate it with machine oil.
- Step four: we lay and nail the sheets with special nails. It is recommended to use at least 20 nails. It should be remembered that it is advisable to nail the material in those places where the crest of the profile wave is highest. To save nails, in some places the sheets can be fastened through one wave. Remember that the fastening should still be solid at the lateral edges.
- Step six: fix the gutter. Be sure to keep in mind that the overlap of the sheet when attaching the drain should be no more than 5-7 cm, otherwise water will overflow through it.
- Step seven: install the eaves protection. For these purposes, as a rule, a special box is used. In addition, a comb must be installed to protect the cornice from insects, birds and various debris. If you do not intend to arrange a ventilated cornice, then you can use a special filler instead of installing a comb.
- Step eight: install the skates. Remember that for the installation of skates, you need to make an additional crate. Also, they are fastened for each wave of the profile, and the overlap between the sheets should be at least 15 cm.
- Step nine: we install special aprons. They are necessary in those places where the sheets of ondulin are in contact with the wall, or the installation of a ventilation system or a chimney is supposed. At the same stage, it is necessary to ensure the tightness of such joints, for which a sealant is used.
Finally, step ten: we install the valleys.
The scheme of their fastening is exactly the same, with one exception - to fasten the valleys, you will have to equip an additional crate.
One of the most popular ways of arranging roofing in private housing construction is laying sheets roofing ondulin... Taking into account the specifics of this modern French roofing material, the technology of its installation has a certain number of features, taking into account which allows you to obtain a high-quality and durable roof.
Installation options and methods
In the modern building materials market, roofing from is one of the most advanced roofing systems that are widely used around the world. Today, there are several options and methods for installing this inexpensive but high-quality roofing material.
To the old roof
A significant advantage of ondulin is that there is no need to dismantle the old roof covering. It is enough just to mount a layer of insulation, on which the roofing sheets are laid in accordance with the same technology as in the process of installing a new roof covering.
Stages of installation on an old roof:
- pulling the rope along the lower segment of the bars and aligning the remaining vertical bars along it, installed at a distance of every fifth wave of wave roofing material or after 60 centimeters;
- fastening the vapor barrier across the slopes using mounting brackets with a pitch of 15 centimeters, followed by gluing the joints with mounting tape;
- installation of a horizontal bar flush with the ends of the vertical lathing and fastening at the points of intersection with vertical bars with 70 mm self-tapping screws;
- the places of layering of two sheets of the old coating should be provided with a cut at the level of the horizontal crate;
- laying of thermal insulation and breathable membrane;
- laying ondulin from the roof section opposite to the prevailing wind.
On roofing material
It is allowed to mantle onduline sheets on the surface of the old roofing material, while all breaks in the old coating should be eliminated. For a high-quality installation, a new counter-batten should be installed in the length of the rafters and the batten across the rafter system. Such work will allow condensation or trapped moisture not to stagnate on the roofing material. A bar with a section of 5x5 centimeters is used.
The counter battens are placed at intervals of the rafters, and the battens are installed at intervals of 60 centimeters. Further, all work on laying the sheets of ondulin is performed according to the attached instructions.
New roof
When creating a new roof from sheet ondulin, preliminary laying of high-quality lathing should be carried out at intervals according to the angle of inclination of the slopes. After completing the lathing, the sheets of ondulin should be carefully marked. To cut the marked roofing material, a wood hacksaw is most often used, which is pretreated for high-quality sliding with oil.
During installation, the basic requirements should be observed:
- the starting row of sheets should be fixed from the side opposite from the blowing wind;
- the next row of sheets is attached from half of the previous one;
- the sheets should be fixed for each wave.
DIY styling rules and technology
- For solid lathing used with a slight pitched slope, moisture-resistant sheet lumber or thin tongue-and-groove boards are used. The maximum gap between such materials should not exceed five centimeters.
- For slopes with an average slope, a thinned crate is required with a distance between the elements - 45 centimeters.
- For a roof with a significant pitched slope, it is necessary to mount a thinned type of lathing with a step of 60 centimeters.
Scheme and instructions for installing ondulin on the roof
By correct execution installation works applied by the manufacturer of ondulin to each manufactured product. The main stages of self-installation of a roof made of sheet ondulin are as follows:
- to facilitate installation work, the ondulin starting sheets should be attached to the opposite leeward side of the roof edge. The second row begins with half a sheet of the first row, which forms three sheets at the corner joint;
- fasteners are driven in along each wave at the end segment and overlap of the sheet, as well as on both sides of the side overlap. Fastening to intermediate battens is made through a wave. Twenty roofing nails are used per sheet;
- the installation of the ridge elements begins at the back of the leeward side of the roof edge using an overlap of 12.5 centimeters. The place of attachment of the ridge elements is the wave of the roofing sheet joining with the ridge and additional lathing bars;
- it is imperative to install valleys, gable elements, as well as correctly form the side roofing joints at the junction with vertical surfaces by means of a covering apron;
- installation of a ventilation system involves the use of a roof fan, ventilation pipe and a special comb;
- to arrange an exit to the roof surface and organize lighting attic space it is required to mount a roof window, which is attached to each wave of the sheet at the junction. By means of the top sheet, an overlap is made on the base of the roof window;
- to perform high-quality waterproofing of the joints of the roofing surface with vertical surfaces, it is recommended to use the Onduflesh insulating tape.
For more information on DIY styling, see the video.
Roofing cost
Despite the fact that the roof covering made of sheet ondulin can be easily assembled independently, many homeowners prefer to use the services of professional craftsmen who not only quickly and efficiently perform this type of roofing works, but also provide a guarantee for all work performed.
The average price of turnkey roofing works, excluding the cost of ondulin, depends on the volume and type of work performed:
- without dismantling old roof, including cleaning the roof, installation of counter-battens and stepped lathing, as well as laying roofing ondulin, ridge, wind and cornice strips and chimney - 400 rubles per square meter;
- instead of the old roof with the strengthening and repair of the rafter system, including dismantling the roofing carpet of the old coating, strengthening and repairing the rafter system, installing ondulin with waterproofing, as well as all accessories - 800 rubles per square meter;
- complete roofing pie with Mauelrat, including insulation, windproofing, waterproofing, vapor barrier and inner lining with ondulin installation - 1200 per square meter.
Summing up
- the basic rule of self-installation of ondulin is to perform all work in strict accordance with the attached instructions;
- you cannot save on the quality of lumber for lathing, and all lumber used in the roofing system must be treated with special antiseptic compounds;
- the type and pitch of the lathing should be strictly observed, depending on the slope of the roof slopes.
