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 any roofing material made of 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;
• resin hardener;
• dye.

Under pressure and at high temperatures, the cellulose base is impregnated with bitumen. After adding plasticizer and other fillers, we get waterproof ondulin. 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. A wide variety of ondulin profiles can be found on the modern market.

What are the advantages and disadvantages of ondulin?

Nowadays, laying ondulin on the roof has gained immense popularity, especially in private houses and dachas. But the question of choosing a roofing material must always 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 technical characteristics:

1. Excellent waterproofing ... As we have already mentioned, the special arrangement of the cellulose fibers prevents water penetration. In addition, ondulin will not swell after long rains and showers, 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. Resistant to temperature changes ... Both in heat and cold, ondulin perfectly retains its abilities and does not deform.
3. 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.
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 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 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 paints were VD-AK-101 or "VAKSA", most of which were developed specifically for painting roofing materials.

Laying ondulin: instruction

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

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

Securing the ondulin on the roof

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

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

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 surface to withstand gusty and harsh winds more firmly. In all other cases, ondulin can easily fall off the roof (read: "").
• 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 the 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. Nails need to be nailed 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:
  
  

• We attach the gutters of the drainage system 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 by laying them with an overlap of at least 120 mm.
• We use special ones to protect 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 in this technique. To master it even better, we advise you to look at the photo and video materials of the installation of an onduline 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!

In the list of modern roofing materials widely used both in the private sector and in industrial construction, a special place is occupied by ondulin (or euro-asbestos), which has such remarkable properties as:

• external appeal;
• lightness and high wear resistance;
• quite reasonable price;
• ease of installation.

Ondulin, which includes bitumen, cellulose fibers, rubber and minerals (as a filler), can be classified as a unique material made in the form of standard wavy sheets that reliably protect roof structures from bad weather.

Before you cover the roof with ondulin with your own hands, it will not be superfluous to get acquainted with some of its distinctive features. Like any roofing material, ondulin has its own advantages and disadvantages. The indisputable advantages of such coatings include:

• high resistance to sudden temperature fluctuations;
• long service life;
• the possibility of laying material blanks on the old coating;
• resistance to biologically active media (mold and mildew);
• high environmental friendliness.

The disadvantages of onduline coatings are:

• flammability of the material;
• the roughness of its surface, contributing to the retention of snow on the plane of the roof;
• a small selection of possible colors;
• "Burnout" of the leaf surface under the influence of direct sunlight.

Features of working with material

As noted earlier, one of the advantages of ondulin is the possibility of its quick installation, combined with the relative simplicity of all operations performed in this case. Taking into account the fact that ondulin is allowed to be laid on the old roofing, the economic effect from its use can be quite large.

In addition, when carrying out installation work with this material, there is no need to use any complex tool, as well as in special training of the contractor. The owner of the building being equipped is able to independently cope with the task assigned to him (even without outside help).

Since the ondulin is soft, OSB sheets need to be fixed over the lathing, which will not allow this roofing material to sag. Ondulin is relatively light and even with OSB sheets, the new roof is much lighter than the old tile and even slate.

In the case when the roof is built from scratch, you will definitely have to prepare a reliable crate of beams, which will serve as the basis for laying ondulin sheets. In addition to its direct purpose (as a load-bearing base), this part of the roofing structure can be used to place on it such important elements as heat and waterproofing.

The lathing for the sheets of ondulin is made with a small step, sufficient so that the coating material does not sag under the weight of accumulated snow, or OSB sheets are stuffed over the old lathing. In addition, the parameters of the lathing should be selected taking into account the angle of inclination of the slope, as well as the direction of the wind typical for your area.

For a classic slope closed by ondulin, the main parameters of the frame base are as follows:

• the optimal angle of inclination of the roof is at least 20 degrees;
• the typical step with which the sheathing beams are stuffed is from 60 to 80 cm;
• with a larger step, it will be necessary to use intermediate slats.

To build a reliable ondulin roof that can last for many years, it is recommended that you familiarize yourself with a number of provisions regarding the installation features of this material.

Such instructions for installation work contain the following recommendations:

1. When moving along the already laid sections of the roofing, you should step on the crest of the wave of the workpiece, since the cavity between them is not designed for heavy loads.
2. All operations for laying the onduline coating are carried out at air temperatures from -5 to + 30 ° C, which guarantees the preservation of the declared characteristics.
3. To fix one sheet blank, at least 20 fasteners from the set of purchased material must be used. The specified number of nails increases the reliability of fastening the material, taking into account possible loads (for example, in strong gusts of wind).
4. For arranging the lathing, bars with a section of 60 × 40 mm are usually used.

Roof slope

In each specific situation, the pitch of the crate is set depending on the angle of inclination of the ramp to be closed:

• with a slope of less than 10 degrees, as a rule, a continuous crate is made of OSB sheets or moisture-resistant plywood;
• at angles of inclination from 10 to 20 degrees, the size of the working step should be about 450 mm;
• at large angles of inclination of the roof, this indicator can reach 600 - 800 mm.

In the first of these cases, the height of the overlap (end overlap) must be at least 300 mm; while the side overlap is made in two waves of the sheet. At large angles of inclination of the roof, these indicators decrease to 200 mm and one wave, respectively. Note also that an ordinary wood hacksaw with a blade oiled with technical oil can be used to fit sheet blanks.

Sheet fixing technique

This subsection tells how to properly attach the ondulin sheet to the crate.

Installation of the first row is carried out in solid sheets, starting from the edge of the roof. To fix them, special nails (resembling screws in appearance) are used, which must be installed in each crest of the wave. When laying subsequent rows, half sheets will be required (that is, cut longitudinally into two parts), which are fixed through one ridge. It goes without saying that each of these sheets (as well as the rows) should be installed with a slight overlap, the amount of which is indicated above.

Sheets, fixed in a vertical position, are fixed on a crate prepared for them with a longitudinal overlap (overlap) of one wave; while the transverse overlap should be about 150 mm. At the final stage of roofing work, the ridge elements of the roof are installed, which are fixed with an overlap along the wave of the sheet used.

The cost of a typical sheet of ondulin measuring 2000 × 950 mm in different regions ranges from 380 to 400 rubles.

The total demand for roofing material, as well as the total cost of purchasing it, is determined taking into account the number of sheets required to cover all roof slopes, the area of \u200b\u200bwhich is calculated by known methods. When determining the total area, one should not forget about the amendment that takes into account the part of the surface hidden under the overlaps (between adjacent sheets and rows).

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 roof structure, 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 roof shape is calculated from the totality of the areas of each of the slopes;
• roof area. It is determined by adding up 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 trims. 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 several more additions to the correct calculation of ondulin:

• when calculating, add 10% or 15-20% additionally respectively to a simple roof or complex roof with different angles and transitions;
• additional elements (ridge, valleys, tongs, aprons around chimneys and windows, junctions) 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 installed 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 ensure the error-free installation of ondulin, regardless of what roof design is provided. The sequence of actions ensures a good result.

Waterproofing and vapor barrier for ondulin

Companies producing 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 membrane from the room side.

Additional elements of waterproofing and ventilation devices:

1. waterproofing of the roof cornice is provided with a special box, which is attached to the base of the sheet overhang;
2. ventilation is provided by ventilation pipes, which, like the window, are fastened with self-tapping screws for each wave of the coating;
3. to protect against insects, a ventilation comb is mounted in the gap under the cornice;
4. the joints of ondulin canvases are glued with a tape produced by the manufacturer of the coating (Onduflesh);
5. 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 work 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

Ondulin, also commonly known as Euroslate, is a lightweight, easy to use, relatively inexpensive and highly reliable roofing material that has been in wide demand around the world for over 50 years. With a strong desire, the installation of the material can be done by hand. You just need to figure out in detail how to properly cover the roof with ondulin and prepare everything you need for work.

In order to cover the roof with ondulin, you do not have to look for and buy some expensive and hard-to-find tools. Special skills and extensive experience are not required for such work either. You just need to grasp the essence of the technology and complete each stage of the work step by step.

When roofing a roof with ondulin, you can be guided by almost the same rules and requirements as when using ordinary slate, which is well known to almost every developer. The biggest difference between the installation technologies of conventional slate and euro-slate is that the latter is characterized by some flexibility, which makes it possible to use it to work not only on flat roofs, but also on more complex structures.

If ondulin is planned to be laid on top of the old roofing, regardless of the type and condition of the existing material, before starting work, it is necessary to inspect the roof rafter system and assess its condition.

You can do this on your own, but in the absence of the necessary skills, it is better to use the help of third-party professional roofers. If the assessment shows that the rafters can withstand the weight of the new roofing ondulin, it will be enough to simply fill a standard wooden crate over the existing covering and mount the euro slate on it. In this situation, not only will a new coating be obtained, but also additional moisture insulation and insulation will be provided.

Due to the fact that ondulin is characterized by a rather low rigidity, the crate for its installation must be fixed with a relatively large step. Determine the step individually. The main thing is that the sheets of roofing material do not sag, otherwise they may simply become unusable under the influence of various kinds of external loads, for example, atmospheric precipitation. Also, when choosing a step, the slope angle of the roof slope must be taken into account.

If necessary, the sheets can be safely cut. For this, it is recommended to use a jigsaw.

In the absence of it, you can get by with an ordinary hacksaw for wood. It is recommended to preliminarily lubricate it with oil so that the sawing is as easy as possible, and the blade does not get stuck during operation.

If it becomes necessary to move along the already laid material when performing work, you need to step strictly on the ridge, because the material between the individual ridges is simply not capable of supporting human weight.

For fastening a separate sheet of euro-slate, at least 20 nails should be used.

Fasteners are included with the roofing material. You don't need to save them, because because of this, the material at one point can simply come off in strong winds. If the installation is done by third-party roofers, make sure that they fasten the sheets in accordance with the given rule.

The properties of ondulin are such that it can stretch somewhat, and many not quite conscientious roofers willingly use this. In an attempt to save time and material, they fasten the stretched Euro slate to the crate to the maximum. This is totally wrong. Quite quickly, the sheets will be covered with waves, which can only be eliminated by completely replacing the roofing. To prevent such problems, it is necessary to fix the sheets in a normal state, without stretching and other deformations.

Before proceeding with the laying of sheets, take the time to carry out the most complete and accurate measurements. Pay special attention to overhangs. If their length is too large, the sheets of ondulin will simply bend and spoil the look of the roof as a whole. If the overhang length is too small, a variety of debris and atmospheric precipitation will fall under it.

Be careful when installing the battens. When choosing a step, it is necessary, as already noted, to be guided by individual conditions, but no one canceled the technology requirements. They will be discussed later. Even the slightest deviation from the recommended values \u200b\u200bcan ultimately lead to a significant reduction in the service life and performance of the roofing as a whole.

Preparation of materials for work

First of all, pay attention to the nails that will be used to fasten the euro slate. Outwardly, they resemble simple screws. The design features allow them to be securely fixed in the wood and ensure the highest quality installation of ondulin. There is a rubber gasket on the top of the mount. The nails in the kit will have it the same color as the sheets of material. Thanks to this gasket, additional moisture protection will be provided at the locations of the mounts.

Where the material meets walls and other vertical elements, valleys specially created for such places are used. In these areas, waterproofing should be of the highest quality.

If there is a chimney in your house, it must be lined with ondulin using special rubber aprons.

To achieve the most reliable and high-quality result, all joints should be carefully processed. Waterproofing must be of the highest standard. Otherwise, moisture will penetrate the roofing, which will lead to a fairly rapid decay of the roofing system frame.

When performing roofing work, it becomes necessary to use various kinds of accessories such as skates, covering aprons, valleys, self-adhesive tapes and others. It is recommended to buy exclusively original components from one manufacturer. This will guarantee the receipt of the roof covering the most harmonious in appearance and the most efficient in terms of performance.

In accordance with the recommendations of professional roofers, a solid lathing is best suited for the installation of ondulin. It will prevent the material from sagging when heated in hot weather and under the influence of snow in winter.

The first thing a roofer must learn to do is to create markings on the used sheets of Euro-slate. The process is complicated by the fact that the sheets are wavy. Marking lines can be applied with ordinary pencils or markers. A straight line can be drawn using a second sheet of material.

To cut sheets, use a hacksaw for working with wood, a jigsaw, or a grinder. The hacksaw, as already noted, must be periodically treated with oil so that the work is done without unnecessary complications.

Standard sheets of ondulin weigh no more than 5-6 kg. This makes working with them as convenient as possible and allows you to lift the material onto the roof without any problems. The finished roofing will also have a relatively low weight, which is an additional advantage.

Installation of sheets begins from the edge of the crate. In order to ensure the most reliable fixation, the sheets should be nailed in each wave. For each sheet of euro-slate, as already noted, about 20 nails should go, maybe even a little more.

For the manufacture of lathing, wooden blocks of 6x4 cm are used. To determine the optimal pitch of the lathing, you need to know the angle of inclination of the roof. If the slope does not exceed 10 degrees, a solid crate is the best option. Plywood is most often used for its manufacture. A material called OSB is also suitable. If the slope of the roof is in the range of 10-15 degrees, the lathing bars must be fastened in increments of up to 45 cm.In the event that the slope exceeds 15 degrees, the largest pitch of the lathing bars will be 61 cm.

First you need to mount the crate. Remember to consider the slope of the roof. It is recommended to start the installation of the bars from the corner that is least blown by the wind. Nail the bars along their axes. Maintain the same distance between the individual battens. If the slope of the roof is such that the bars have to be fastened with a large pitch, additional slats must be mounted between the bars at a distance of 30-50 cm from each other. They will help increase the strength. But a solid crate, as already noted, is the most preferable and effective option in all respects.

Detailed instructions for installing ondulin

The fastening of the roofing material in question must be started from the lower corner of the roof to be finished. At the same time, the installation technology is such that the starting sheet of the 2nd row should be cut longitudinally in half. Euro-slate sheets are mounted horizontally. For fastening, it is strongly recommended to use exactly those nails that come with the factory set with the roofing material. Fix each sheet with an average of 20 screws.

In the starting row of the euro slate, nail the fasteners to the top of each wave.

In the rest of the sheets, the fastening must be installed in every 2nd ridge. The second row of material must be laid with an overlap, grabbing a sheet from the first row of ondulin, etc. The hats of the fastening nails, as noted, are fitted with rubber gaskets in the same color as the ondulin, so that the finished roof will have a uniform and harmonious appearance.

However, in some situations, the caps become quite noticeable. Nail them in one line to achieve an attractive appearance. To ensure that the fasteners are held evenly, you can pull the rope and drive nails along it.

Euro-slate must be nailed to the sheathing beams vertically with a mandatory transverse overlap equal to about 15 cm. Make the longitudinal overlap so that its length is not less than the length of the first wave.

At the end, you need to fix the ridge elements. The technology for their installation is extremely simple. These accessories are overlapped and fixed along the euro-slate wave. If ondulin is used for a roof with a gable structure, the ridge is trimmed using special corner pieces. Endova is made with the obligatory arrangement of one more additional crate.

An instruction should be included with the roofing material in question. In full-fledged instructions from trusted manufacturers, not only textual recommendations for fixing ondulin are usually given, but also a variety of drawings, thanks to which the installation becomes understandable to any person, regardless of his skills and experience.

The size of a single sheet of the Eurosphere is 2000x950 mm. One such sheet weighs about 5800 g. Each wave usually has a height of 3.6 cm. There are 10 such waves in total.

Competent installation, carried out taking into account all the basic requirements and rules, will make it possible to equip such an ondulin roofing that will reliably serve 50 years or more. Manufacturers usually give a 15-20 year warranty. Do not forget to ask the seller for a warranty card, a fire certificate and a hygiene certificate.

How to fix ondulin - instructions

Thus, in the roof of the roof with ondulin there is nothing super complicated. You just need to carefully understand the instructions for laying euro slate. The article contains all the necessary information that you may need while working. Follow the basic recommendations and basic rules for arranging an onduline roof and everything will work out.

You can not only save money on the services of third-party roofers, but also independently control the entire process from its beginning to fixing the last element. To make everything even clearer, be sure to watch the video that demonstrates the main stages of fixing the ondulin on the roof.

Video - How to properly cover the roof with ondulin

Let's remember the school geometry course

The hip roof consists of 4 slopes. Two of them are in the shape of a trapezoid, and two more are in the shape of an isosceles triangle.

When installing rafters 4-5 meters long, the difference in the length of the sides of a triangle or trapezoid of 5 centimeters may seem insignificant. However, this difference makes isosceles triangles just triangles, and trapeziums quadrangles with different side lengths.

"How can this affect the roofing materials installed on the roof?" - you ask. We answer - in the most negative way.

Installation of ondulin must be started from the lower edge of the slope. Installation of sheets in such a way that their upper and lower cuts are parallel to the lower cut of the ramp will lead to the formation of a wedge to the ridge on the ramp.

In order to close it, you will have to cut each sheet of the upper edge individually, sitting on the roof. That is, a small difference in the size of the rafters will lead to a significant increase in waste, labor costs and the cost of roofing work, and also significantly increase the likelihood of leaks and the fact that roof repairs will have to be done very often.

In addition, the lines of the rows on adjacent slopes will not look parallel, which will give the roof a sloppy, unattractive look.

What needs to be done before starting the installation of ondulin

Before installing the ondulin, it is necessary to check the correctness of the geometric shapes of the slopes. Or, as the builders say, check the geometry.

Anyone who is building a house with his own hands can do this work on his own by inviting only one assistant.

The task that needs to be completed is quite simple - to check the correspondence of the sizes of the sides of the slopes (triangles and trapezoids)

To do this work, it is enough to use any strong thread or braided fishing line. It is not recommended to use monofilament line - it can stretch a lot.

Should be of the same length:

1. Lateral sides of trapezoids.

2. The sides of the triangles.

3. Diagonals of trapezoids.

Diagonals are the distances between the lower left and upper right points of the trapezoid, as well as between the lower right and upper left points.

Council. Since the lateral sides of the trapeziums in our case are simultaneously the lateral triangles, the execution of points 1 and 2 can be combined.

If the above dimensions are the same, proceed with the installation of ondulin. If a difference is found, eliminate it. This is done quite simply - by sawing off excess or installing overlays.

Although this work is carried out only in relation to the outer rafter legs, before installation, after the string orienting the lower edge of the lower row of roofing materials is stretched, you should carefully examine the roof slope and make sure that the lower ends of the remaining rafter legs are not located below the cord.

If you find the ends of the rafter legs lowered below, it is necessary to shorten them to the level of the cord. Neglecting this rule will lead to the fact that the installation of wind boards and the filing of the cornices will be difficult, and they themselves will turn out to be uneven.

How to properly mount ondulin on a hip roof

The installation of the lathing (and, if necessary, counter-lathing) under the ondulin on the hip roof is fundamentally no different from the installation of the lathing on the slopes of the gable roof.

There are 3 nuances that you should pay attention to:

1. The slope of trapezoidal and triangular slopes can be different. Therefore, the pitch of the crate on different slopes should be selected in accordance with the slope.

2. Since the lathing on adjacent slopes can have a different pitch, special attention should be paid to the places of their mates and the installation of reinforcement under the ridge, valley and tongue.

3. In order to maximally protect your home from the harmful effects of external factors, you should use Ondutis roofing films.

The beginning of the installation of Ondulin roofing sheets on the hip roof slopes is slightly different from the beginning of the installation of roofing materials on a gable roof.

The first to take cover are the trapezoidal rays.

The ondulin sheet, mounted first in the bottom row, is laid on the roof in such a way that its lower point (closest to the edge of the corner rafter) is 10 - 20 mm from the lower point of the slope. After that, a marking is made, the part of the ondulin sheet protruding above the edge of the slope is cut off, and the sheet is nailed to the crate with branded nails.

It is impossible not to pay attention to the fact that ondulin can be cut with a hacksaw or knife, and the weight of an ondulin sheet is only 6 kg, which allows all the described works to be performed without lowering the roofing materials of Ondulin to the ground and without using electricity. This is a serious competitive advantage over slate, metal tile and profiled sheet, since it reduces the time of work and (if the work is performed by hired roofers) its cost.

The bottom row of ondulin sheets is laid in accordance with the installation instructions. The last sheet of the row is laid in the same way as the first (with preliminary marking and cutting).

The installation of the second and subsequent rows is carried out in the same way as the installation of the lower row - the outer sheet is marked and cut in place, the remaining sheets are fixed in the traditional way, the last sheet is marked and cut in place. It is obligatory to shift each next row relative to the previous one by about half a sheet.

“Why about? The Ondulin company demands to shift exactly half a sheet! " - you ask.

The fact is that a situation may arise in which the first sheet of the row will be small (for example, 1 wave wide). It is not possible to securely fix such a piece, which increases the appearance of leaks. In this case, it is rational to shift the entire row by 1-2 waves and nail a trimmed sheet of ondulin of a decent size. The main thing is not to join 4 sheets at once in one place.

A similar situation can arise when mounting the last sheet of a row. In this case, the overlap should be increased by 1-2 waves, which will increase the size of the last sheet.

After laying on trapezoidal slopes, ondulin is mounted on triangular slopes.

Particular attention should be paid to the installation of the ridge element. We have already described how to properly mount the ridge on a hip roof. We recommend that you strictly adhere to the installation instructions when performing work.

The installation of ondulin at the exit points of pipes requires no less attention - it is necessary not only to correctly mount the ondulin sheets, but also to reliably isolate the junction points. Poor performance of these works will lead to the imminent appearance of leaks, which means that roof repairs will be required.

In the modern world, more and more varieties of roofing materials appear every year, but at the same time, long-known types of flooring are not inferior in their popularity. Particularly appreciated by users are coatings with high strength, long service life and a simple installation process. It is to such products that roofing ondulin can be attributed, that is, sheets of cellulose impregnated with a bitumen mixture. Of course, this is a fairly general idea of \u200b\u200bthis material, since it contains many components and additives that make the product strong, resistant to aggressive environments and durable. Today, it is not difficult to cover the roof with ondulin, even without involving professional builders in the process. However, before deciding on such a procedure, you should carefully study all the subtleties of the work, as well as the properties and characteristics of the material. To properly cover the roof with ondulin, you first need to familiarize yourself with the composition of the product in detail.

Ondulin characteristics

More than 70 years ago, at one of the Parisian factories, it was decided to release a new product based on cardboard and bitumen. This product was an onduline flooring, which was appreciated by consumers from all over the world, because it is this material with its low cost that has a fairly high reliability. Manufacturers give a guarantee for ondulin roofing for up to 15 years, however, in practice, you can make sure that such a flooring can last for a much longer period, up to 50 years. How is it possible to achieve such an effective result? Many users know that covering the roof with ondulin means providing a reliable shelter from negative environmental factors, as well as giving the house an aesthetic appearance. Let's analyze the composition of the material in more detail. The following ingredients can be considered the main components:

• refined bitumen;
• cellulose fibers obtained from cardboard production waste;
• fiberglass;
• mineral fillers;
• various resin impregnations.

However, you can get a quality product only if you follow a certain manufacturing process.

Ondulin production technology

To obtain high-quality material that allows you to competently cover the roof with ondulin, the raw materials must be subject to preliminary control. First of all, all garbage is removed from the waste paper, then the peeled paper is processed into pulp. Further, the paper pulp goes through a drying stage on a special conveyor, where the pulp is shaped into corrugated sheets. At the next stage, the web is cut into pieces of one length and impregnated with a bitumen mixture. This process is accompanied by increased temperature and high pressure, due to which the sheets are impregnated evenly and with the highest quality. To increase the tensile strength of ondulin, as well as to give the products more elasticity, resins, fiberglass and mineral fillers can be added to the composition. Coloring of sheets is carried out in total mass, before impregnation with bitumen, thanks to which the saturated color remains for many years. And these are not all the positive aspects of the material.

Benefits of onduline coating

First of all, it should be noted that the sheets are made on the basis of only natural ingredients, which means that one of the advantages of ondulin is its environmental safety. You can also name such positive aspects of using the coating:

• minimum water absorption, due to which moisture does not enter the under-roof layer;
• frost resistance of products;
• resistance to weather factors, that is, the flooring is not afraid of snow storms or torrential rains, and the coating also withstands hail, strong winds and UV radiation;
• antibacterial, this quality prevents the development of fungi, mold, bacteria and other microorganisms on the surface of the roof;
• resistance to chemical components (acids, alkalis, gases);
• ease of installation - to cover the roof with ondulin, you can use the tools of a home craftsman;
• ease of care;
• affordable cost;
• low specific gravity, which allows the material not to exert significant pressure on the load-bearing walls of the building.

Also, do not forget that this is a product with a long service life. Ondulin has a wide selection of colors, but mostly matte colors - red, green, black, brown and their shades.

Physical and mechanical properties

The main characteristics of the ondulin material are presented in the table.

Many people compare ondulin with slate. However, the main difference between ondulin roofing and slate is that this material does not contain asbestos. And working with ondulin is much easier, because it does not crumble and does not break even when nails are driven into it. In addition, it is a fairly economical material with an affordable cost. However, it is definitely not possible to answer the question of how much it costs to cover the roof with ondulin. After all, you need to know the dimensions of the roof, as well as which technology was chosen as the main one. But it is not at all difficult to calculate the approximate cost, it is enough to know the cost of one sheet and the parameters of the roof. Experts recommend adding 5-10% to the final figure.

1. Sheathing device for ondulin. In the instructions for the material, in order to cover the roof with ondulin, it is recommended to arrange a continuous crate. This allows you to fix the products as firmly as possible and preserve their appearance for many years, preventing subsidence during heavy snowfalls. In addition, this is the only way to move on the roof without any problems. The lathing can be made of 60x40 mm timber, OSB-boards or plywood. The specific step will depend on the angle of inclination of the roof:

2. Cutting ondulin. To cover the roof with ondulin, it is necessary to properly prepare the material. Since the sheets have a wavy profile, it can be problematic to mark the first time. To cut an ondulin of the required size, it is enough to use a pencil, a long ruler or another ondulin sheet and a grinder. Also, the size can be made with a hacksaw for wood, just apply a lubricant to the blade, which will help to avoid the saw getting stuck.

3. Fastening the ondulin. You can fix the sheets using the ondulin roofing nails supplied in the kit. Such products are equipped with a special decorative cap to match the sheets and a rubber lining that prevents damage to the ondulin. However, it is possible to properly cover the roof with ondulin using ordinary self-tapping screws. The sheets are not very heavy, so they can be carried without the use of technology. Installation begins from the bottom edge of the sheathing, for this the sheet is leveled on the roof and pierced with nails along each wave. The consumption of screws or special nails is approximately 20 pieces per sheet. Then the second sheet is overlapped on the first sheet and also fixed. Thus, the entire row is traversed, after which you can proceed to fixing the second and subsequent rows with layering on the previous ones by at least 20 cm.

Important! One of the disadvantages of the material is its flammability. Therefore, when deciding how to cover the roof with ondulin near the chimneys, it is worth taking care of installing additional layers of hydro and thermal insulation, as well as using a special element (apron) made of rubber.

The easiest way is to cover the roof with ondulin with your own hands if the house has a gable roof. The situation is more complicated in the case of a hip roof, in other words, a structure with four slopes (hipped roof). The first step is to measure the rafter system and make sure that the sides of the triangles and trapezoids are of equal length on both sides. If one of the sides is larger, then it is necessary either to saw off the structural element from this side, or, conversely, add the corresponding length from the opposite. In addition, during the installation of the lathing, the angle of inclination should be taken into account, since the trapezoidal and triangular slopes have different angles, the pitch of the lathing will also change. In general, such a roof covering with ondulin practically does not differ from the device of a gable roof. That is, it is advisable to adhere to the following rules:

• installation is required only at a temperature range from -5 to +30 degrees on a windless day;
• the sheet is fixed in its natural state, it does not need to be stretched or squeezed;
• overhangs should not be too small (leads to rainfall entering the under-roof space) or large (over time, the sheet deforms and spoils the aesthetics of the roof).

Ondulin roofing has many positive qualities, it is durable, attractive in appearance, and, in addition, has an affordable cost. Of course, its main undeniable advantage is that you can even cover the roof with ondulin on your own.

How to cover the roof with ondulin with your own hands: the right technology

How easy is it to cover the roof with ondulin with your own hands?

Roofing is the last stage in the construction of your own home before the start of interior decoration and connection of communications. To reduce the time spent on roofing, you can do the installation of ondulin yourself. Ondulin is a modern bitumen-based coating, the laying technology of which allows you to mount the material both on a new roof and on an old one without disassembling the structure. 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 show you how to properly cover your roof with ondulin to get a durable, airtight coating that will withstand winter frosts and summer rains.

Material characteristic

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 technology for the production of this coating consists in obtaining purified cellulose fibers, making sheets with a wavy surface from them, dyeing and impregnating them with petroleum bitumen. Covering the roof with ondulin makes the structure waterproof, resistant to temperature changes, shock-resistant, but at the same time lightweight. Due to the low weight of each sheet, the installation of ondulin can be performed on the old roofing material without dismantling the structure. This material has the following advantages:

1. A light weight. Each sheet of ondulin of a standard size weighs only 6 kg, so a blood device made of this material does not require the establishment of a massive frame or reinforcement of the foundation.
2. Ease of installation. Do-it-yourself ondulin roofing is done in 1-2 days without the involvement of hired workers, since such a coating can be mounted without special tools and experience.
3. Flexibility. Sheets of this material based on bitumen have a certain flexibility, which simplifies the laying of ondulin on a roof of complex shape, which includes valleys, slopes of different slopes, ribs and dormers.
4. Affordable price. The ondulin roofing device does not require large costs from the homeowner by saving the lumber used for the construction of the frame and performing the installation on its own.

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

Roof device

Before you cover the roof with ondulin, you need to understand the composition of the roofing cake, which is made for this type of roofing material. Roofing with molded cellulose impregnated with bitumen is easy to install due to its light weight. It consists of the following elements:

• Rafter frame. Fastening of the roofing material is carried out on rafters made of natural wood with a section of 50xx150 mm, the pitch between which is 50-80 cm. Since the material is lightweight, usually the frame is not burdened with additional elements.
• Insulation. Before laying ondulin, thermal insulation material is placed between the rafters. The most commonly used mineral insulation materials (basalt wool, glass wool, slag wool).
• Vapor barrier. Insulation laying technology involves the use of a vapor barrier membrane that protects the thermal insulation material from below from steam penetration and wetting.
• Waterproofing. To protect the wooden frame elements and insulation from possible leaks or condensation, a waterproofing film is laid. The waterproofing is fastened to the rafter legs using a construction stapler.
• Counter grill. Before laying ondulin, counter-lattice slats are nailed over the waterproofing along the rafters, which organize the ventilation gap necessary for air circulation inside the structure.
• Lathing. The type of lathing is stipulated by step-by-step installation instructions. Ondulin must be nailed to a solid crate made of moisture-resistant plywood or a lattice made of unedged board, 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 crate with special nails, overlapping the sheets on each other by 10-15 cm.

Please note that before covering the roof with ondulin, most professional craftsmen process the wooden frame elements with antiseptic impregnations and fire-blocking compounds to protect them from fire and decay.

Required materials and tools

Many inexperienced craftsmen are wondering how to properly cover the 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 the installation is often done by hand. To erect a roof from ondulin use:

1. Ondulin sheets with dimensions 0.95x2.05 m required to cover the entire roof area with a margin of 10-15% for trimming and overlaps.
2. The ridge profile for the entire length of the ridge, taking into account the overlaps between the elements 10-25 cm.
3. Fasteners. Special nails for ondulin with a rubber head are made of carbon steel and painted to match the material.
4. A bar with a section of 40x40 mm or 60x40 mm for the construction of the lathing, treated with an antiseptic.
5. Waterproofing membrane or film.
6. Sharp hacksaw for cutting sheets.
7. Light hammer for hammering in nails.
8. Screwdriver for fixing the battens.
9. Ruler, tape measure and building pencil for measuring and marking.

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

Installation technology

Even without knowing how to fasten ondulin, an inexperienced master can easily cope with this task alone, since the sheets of material are easily processed. However, do not forget that the reliability and service life of the roof depends on the quality of installation. For ondulin flooring, the following step-by-step instructions are used:

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

Not knowing how to lay 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 the elevated temperature leads to deformation of the sheets. It is forbidden to stand on the ondulin during installation, as it may break or change shape.
