Installing ondulin with your own hands. Laying ondulin: sheet markings, properties and proper use of the material (90 photo ideas)

Ondulin (euro slate, onduline) has been used as a roofing material for more than half a century. During this time, it has proven itself to be excellent, facilitated by such advantages as ease of installation of ondulin, low weight and affordable cost.

Roofing ondulin is preferred by people who care about the environmental friendliness of their home. After all, Euro slate does not contain asbestos, which is prohibited in many countries; it is based on cellulose mixed with bitumen. And minerals and binding additives provide it with strength and reliability. Besides, a private house, covered with ondulin, is beautiful and elegant.

The warranty period for ondulin is 15 years, provided that the ondulin installation technology is followed. This is where we will stop. Let's consider step by step what requirements need to be met in order for the quality of work to meet the standards.

Technology for installing an ondulin roof in stages.

1. Calculation of ondulin on the roof

The easiest way is to use the calculator on the seller’s website or contact a consultant. But in order to have an initial idea, you need to divide the total area of ​​​​all roof slopes and divide by usable area one sheet. Add 5 to 15% for waste. The amount of waste depends on the complexity rafter system.

2. Installation of sheathing under ondulin

Due to the fact that ondulin is a flexible roofing material, its installation technology involves attaching sheets to a wooden sheathing. For roof sheathing under ondulin, 60x40 timber is used.

Sheathing pitch for ondulin

  • a slope angle of up to 10° (1:6) requires the installation of a continuous sheathing, otherwise the sheet will bend;
  • angle 10 - 15° (1:4) - sheathing pitch 450 mm;
  • angle over 15° - pitch 610 mm.

Nuance. Professionals advise not to skimp on the sheathing and to make it continuous in all cases. In this case, the sheets will not bend either from the heat or under snow or wind loads.

Installation of additional battens An error in nailing the sheets can lead to the sheet becoming deformed, so the sheathing timber must be fastened correctly.

You can ensure their parallel arrangement if you use a pattern. Laying a piece of timber between the previous and subsequent sheathing timber will be a good help.

In the place of future fastening ridge strip additional battens need to be installed.

Note. Installation waterproofing film is not a mandatory step when installing an ondulin roof. Therefore, the need for its installation is determined by the owner.

3. Installing the valley strip

Please note that it is installed before the installation of sheets begins. Its installation is carried out on special clamps. You need to make an additional continuous sheathing underneath. The process of its arrangement is shown in more detail in the diagram.

Installation diagram for the valley stripInstallation of the valley strip

4. Installation of ondulin sheets

Ondulin marking Installation begins with the correct markings. Using a pencil, you need to draw a thin line along which the screws will be screwed. The lines on the sheet are located at a distance equal to the distance between the sheathing bars.

Advice. To make the line even, despite the ondulin waves, you can do the following: mark the distance along the height of the wave, lay the sheet on the sheet and draw a line along the second sheet. Then the first one will have a smooth and clear stripe.

Cutting ondulin To prevent work at height from creating inconvenience, you must first cut the ondulin into certain pieces (if the cottage has broken slopes). You can cut ondulin using a jigsaw, grinder or hacksaw.

In order not to get confused about where to attach which sheet, you need to number them and put the numbers on the drawings.

Advice. To prevent the saw from getting stuck in the ondulin, it must be lubricated with oil.

How to attach ondulin correctly?

To do this you need to adhere to technology. First, let's start installing the first sheet. It is recommended to start work from the leeward side. Then the covering wave will not be subject to wind load.

Sequence of laying ondulin sheets taking into account wind load

In addition, due to some properties of ondulin, during its installation it is necessary to maintain a certain temperature regime.

Ondulin is mounted at temperatures from 0 to 30°. Working in this temperature zone eliminates two disadvantages of ondulin:

  • fragility to fracture. This is due to the fact that in colder times the risk of material damage and cracks increases.

    Nuance. If you need to replace the sheet, it is better to pre-drill holes for the screw in the sheet.

  • stretching the material. Therefore, in hot weather, the material should not be laid stretched.

Advice. Many workers try to reduce installation time by nailing stretched sheets. When the temperature changes, such a sheet becomes deformed. Subsequently, in order to eliminate such defects, it is necessary to completely cover the roof.

Correct installation of the first sheet of ondulin will make installation easier. Therefore, you need to carefully align the sheet along the end and the cornice. At the same time, ondulin should not protrude beyond the cornice by more than 50 mm. Otherwise, water will overflow through the gutter drainage system, and the sheet itself may bend, which will not look aesthetically pleasing.

Nuance. The first and each subsequent sheet is firmly attached, only after checking for horizontalness. To do this you need to use a level.

The procedure for attaching subsequent sheets of ondulin is shown in the photo.

Ondulin is laid in a checkerboard pattern with obligatory longitudinal and transverse overlap. To achieve this, installation of the second row begins with half a sheet.

It is important to know that the amount of overlap is affected by the angle of inclination of the slope. Namely:

  • the slope angle is up to 10° - the longitudinal overlap is two waves, the transverse overlap is at least 200 mm.
  • an angle of 10-15° - the longitudinal overlap is one wave, the transverse overlap is at least 160 mm.
  • angle over 15° - the longitudinal overlap is one wave, the transverse overlap is at least 140 mm.

5. Laying ondulin on the roof

The reliability of fastening euro slate depends on the type of hardware used and the method of fastening it.

Self-tapping screws with a drill for metal Since all fasteners remain visible and other methods have not yet been invented, it is better to use hardware with a head that matches the color of the material. In addition, they consist of a nail, a wide head and a gasket - this ensures tight installation.

For metal sheathing, self-tapping screws with a metal drill are used.

Material prepared for the website www.moydomik.net

Nails with special head For wooden sheathing Nails with a special head are suitable, which protects the metal from external factors.

Such nails require attention during installation.

It is impossible to cover a heavily hammered nail or one that is not completely hammered in with a head. As a result, the reliability of fixation decreases.

Nails with a monolithic head Professionals advise using new nails for ondulin. Their cap is monolithic and can withstand hammer blows.

The hardware is attached strictly to the wave, to its highest point. At the same time, the lower and top part The sheet needs to be secured in each wave, and in the middle - in a zigzag.

The hardware fastening diagram is shown in the photo.

6. Additional elements (ondulin components)

The installation of ondulin does not end there. To your Vacation home had a presentable appearance, and the roof was reliably protected from leaks, you need to install decorative elements. These include the ridge, cornice, wind strip and valley.

The ridge is mounted at the junction of two slopes. The mandatory overlap must be at least 120 mm. You can buy a skate, or you can make it yourself. For this top sheets they are wound through the joint and nailed to the top of the opposite slope. True, this can only be done when it is hot outside and the ondulin is soft enough. The place where the ridge is attached can be decorated with a wooden plug.

Nuance. The ridge is installed on pre-installed battens.

Lining tape under the ridge A special insulating self-adhesive tape must be placed under the ridge. If you skimp on it, the snow will be blown under the ridge and flow onto the roof. After all, waterproofing is not provided for ondulin. And, the design shown in the photo will reliably protect the attic or attic from rain and melt water.

Sealing tape under the overhang of an ondulin sheet Advice. The same tape can be installed in the place where the ondulin sheet overhangs. This will prevent snow from blowing out from under the eaves strip, and will also allow you to implement natural ventilation in the attic. In addition, the attic will become inaccessible to small birds or insects.

The construction of unventilated roofs involves the use of sealant instead of tape.

  • The cornice or wind strip is installed according to the wave of the sheet. The overlap should be at least 10 cm.
  • Adjacent to a wall or around protruding elements. For this purpose, a special covering apron is used. Its use guarantees a sealed roof assembly.

7. Natural light

In order to ensure the penetration of daylight, you can install a hatch window under the ondulin. Regular skylights are not suitable for these purposes.

However, today the market offers such a material as translucent ondulin. During installation, a regular sheet is replaced with a translucent one, this can significantly reduce the time, complexity and cost of installing windows.

Translucent ondulin

You can give an ondulin roof an exclusive look by combining different colors during the work process.

Conclusion

As you can see, working with a material such as roofing ondulin, you can cover the roof of not only a private house, but also a garage, gazebo or bathhouse. If you adhere to the tips and recommendations, and also follow the instructions, you can install an ondulin roof with your own hands.

Tags: Roof Roof Ondulin Euroslate

Today there are many varieties roofing materials. However, not all materials meet the requirements and have high quality indicators. Euroslate has gained popularity in the construction market for a reason in a matter of years, but one way or another its popularity has somewhat deteriorated due to the emergence of serious competition. However, laying ondulin can be done on top of the old coating without dismantling it, and this is expensive.

Positive and negative sides of ondulin

Before talking about how to lay ondulin, you need to understand the properties of this material.

Euroslate is used exclusively in private construction. This material is corrugated sheets, in appearance resembling ordinary asbestos slate. The sheet contains natural cellulose, modified bitumen and other components that increase the waterproofing qualities of the product.

The advantages of ondulin.

  • Good waterproofing performance. This property is achieved by a combination of the right components included in the product. Natural cellulose fibers are laid in such a way that water cannot pass through them, not to mention the main insulating component in the form of bitumen. Ondulin can withstand a large number of moisture and at the same time not change its geometric parameters, although there are plenty of fakes on the construction market.
  • Good resistance to temperature changes. Layed sheets of Euro slate are not afraid of heat and cold. When creating a high-quality foundation, they will not be deformed in any way.
  • Resistance to chemical and biological activity. Special additives protect the material almost 100%. You will never notice any mold or fungi on a Euroslate roof. As for alkalis, oils and acids, the surface simply does not react with them in any way.
  • The most big advantage this product can be considered light weight. Due to this, installation work can be carried out independently, without any partners. In addition, it is allowed to place ondulin on the roof on top of the old covering, without dismantling it. This feature will significantly reduce upgrade costs roofing. It is worth noting that before such a procedure it is worth recalculating the maximum load on the roof, since to attach the sheets you will need to knock down the base.

Disadvantages of Euroslate.

  • Work on installing bituminous materials on the roofing surface is strictly limited by weather conditions. As you know, the material contains a large amount of bitumen. When interacting with low temperatures, the sheet becomes very fragile and can easily break at the slightest deformation. As for the heat, the bitumen begins to show excessive elasticity and may even leak along the sheathing.

  • The second serious drawback is the fast loss of color contrast. The sheet surface does not have any protective layer that could reduce the impact sun rays Therefore, after a short period of time, color loss will begin. For some residents this can be a serious problem, while others simply do not pay attention to it.
  • Rough surface will not allow precipitation to winter time years to be removed naturally, therefore it is necessary to create roofing systems with as much of a slope as possible.
  • High degree of fire. According to this clause, such a coating cannot be laid on the roofs of public buildings, which is why the material can only be found in private construction.

It is worth noting that ondulin roofing refers to a soft roof and continuous sheathing is suitable for installation. But due to the fact that the sheet has good rigidity, it can still be attached to a discharged base, but with a minimal step.

Installation nuances

For any roofing works ah, there are certain nuances. It is better not to stack some materials with others, or you can use only boards to create the sheathing. Now we will discuss all these points in more detail, and you will understand how to correctly place ondulin on the roof.

Laying ondulin on the roof should be carried out according to some technology, but there are nuances that cannot be ignored, especially the question of “how to attach ondulin to the roof?”

For installation work you should choose suitable weather conditions. You already know that at subzero temperatures, euro slate sheets begin to crumble, and in extreme heat they simply melt. Optimal value The thermometer should be in the range from plus 10 to plus 25, only then can the coating be laid without any structural deformations.

In addition, you cannot lay this material in the rain. If construction is being carried out from scratch, then covering a wet roofing pie is the same as using bricks as a foundation for a heavy house. When it rains, all the lumber will get wet and some of the protective impregnations will be removed from them; in addition, moisture will remain in the attic for a long time, since the coating will not allow it to escape outside.

When installing sheets, do not try to stretch them. Such actions are often committed by unscrupulous hired roofers. They try to stretch the sheet of paper as much as possible in order to enlarge it working area, of course, with small volumes it makes no sense to do this, but when the area goes beyond 200 square meters, then there is something to profit from.

By stretching the sheets, workers can complete the job faster and at the same time save a couple of sheets, which will successfully go with them at the end of the working day. The owner, fooled in this way, will face expensive repairs to replace the roofing sheet next spring, since all laid sheets will crack when sub-zero temperature.

If during the installation process it becomes necessary to divide the material into some parts, then it is best to do this with a regular hacksaw. For speed of work and easy cutting, its blade is lubricated with oil. When handling power tools, be careful, the material is very flammable and supports combustion. long time.

Before laying ondulin on the roof, you will have to acquire special fasteners. They can come complete with Euro slate sheets or they will have to be purchased separately. Ondulin is fastened to the roof using special screws or nails. The consumption of fasteners per sheet is about 20 pieces. It is best to arrange them as follows: half goes to the bottom of the sheet, part to the middle and the rest are placed on top. By the way, a mount for ondulin is available different colors, therefore, to improve the aesthetic properties of the surface, it is better to choose a suitable tone.

The basis will depend on roof slope. If the slope is less than 10 degrees, then you need to knock down the continuous sheathing. It is created from two layers. The main elements of the first layer are timber or board. OSB boards or moisture-resistant plywood are laid on top of them. Some developers fill the boards, but I do not recommend doing this. The resulting plane will not be level, and the curvature of the base will significantly affect the lifespan of such a roof. An exception may be a calibrated board, where all dimensions are adjusted to one size.

If the slope is in the range from 10 to 15 degrees, you can lighten the sheathing a little. Stick to a maximum step of 30 centimeters. With such a slope, this is quite enough to transfer all temporary loads. If the slope of the slope is more than 15 degrees, then the step can be taken even larger: up to 45 centimeters.

IMPORTANT: When laying the discharged base under sheets of Euro slate, everything important places are still equipped with continuous sheathing. These include the valley, ridge and cornice units.

Now, let's move on to the next point and look at how to lay ondulin with your own hands.

Laying ondulin: instructions

If you want to install the coating yourself, but do not know how to lay ondulin on the surface, then this item is just for you.

When purchasing roofing material, carefully study its qualities. Ask the seller about the company and the delivery of this product to his warehouse, storage conditions and the like. Due to loss of popularity, it may turn out that Euro slate has been in storage for a long time, therefore, it may lose some qualities that are important to you.

If this is your first time working with this material and you don’t know how to attach ondulin, then remember how to lay ordinary slate. With zero construction there will be absolutely no differences here.

Instructions: how to properly place ondulin on the roof.

  • You can start laying ondulin from any side. The first sheet is placed along the edge, taking into account the pediment and eaves overhang. You already know how to properly attach ondulin, so I don’t see the point in focusing on this. The only thing that needs to be said is that all sheets are laid in an overlap, the value of which is taken based on the slope. The optimal value of vertical overlap lies in the range from 15 to 30 centimeters. As for the horizontal, it is 1-2 waves.
  • After laying the first sheet, proceed to installing the second. The row is filled in the same way.
  • Half of the sheet, cut lengthwise, is placed at the beginning of the second row. This is done in order to separate the seams and increase the tightness of the entire plane. The cut edge is hidden under the overlap and never laid towards the gable.
  • Thus, alternating whole and cut material, the slopes are filled.
  • After this, install additional elements and the building is put into operation.

If you don’t understand anything, watch a video about how ondulin is installed on the roof:

Before laying the coating, care must be taken to create a high-quality roofing pie. It should include the following materials:

  • Waterproofing material. It would seem that the roofing covering will ideally protect all underlying elements, but everything is not so simple. Humid air enters attic space not only from the outside, but also from the inside. During human activity, liquid is released, which rises and concentrates in the attic.
  • Thermal insulation. Despite the considerable thickness of the sheet, it has high thermal conductivity, therefore, all the heat will escape through it.
  • Litter. Some developers use underlay carpet. It levels the surface and creates another layer of insulation.

As you can see, anyone can create a roof from Euro slate, the main thing is to choose high-quality materials.

Ondulin roofing is a fairly lightweight and at the same time durable material that is widely used in construction. For most developers, these corrugated sheets are great opportunity rapid construction a new roof, as well as dismantling the old slate. The main characteristics of ondulin roofing include high reliability, operation over a long period (up to several decades), it is suitable for structures of any complexity, and can also be used in the repair of structures for any purpose, even in the most severe climatic conditions.

The technology for installing ondulin is quite simple, and with the help of the proposed instructions, the work can be done not only efficiently, but also quickly.

If you decide to lay a roofing covering, you will be able to handle it yourself, because the light weight of Euro slate sheets allows you to transport and install the material without special equipment and construction skills. It can be used in the construction of roofs of houses, cottages, bathhouses, gazebos and other outbuildings.

Ondulin roofing has a significant advantage over other roofing materials - the sheets can be attached directly to old roof. This ondulin installation technology helps reduce material costs for replacing the previous coating, and also does not require disclosure interior spaces buildings located under the roof.

Before starting installation work, it is recommended to read the instructions supplied by the manufacturer complete with ondulin and its components. In addition, the instructions have another function - it usually indicates the presence of a factory warranty. The consumer has the right to make any demands in relation to the manufacturer only if all the conditions listed in the instructions are met.

It is also important that the legal guarantee applies to the original ondulin, which was purchased from an official representative or partner of the manufacturer.


In case of installation construction team, the customer must also know about the main stages of work in order to monitor the quality of the roofing installation.

List of rules for installing ondulin roofing


As a rule, the instructions for installing ondulin involve minor deviations or the implementation of actions at the discretion of the developer, however, if there is insufficient experience in such construction, it is better to refuse to do it on your own.

Below is suggested detailed instructions for laying ondulin coating.


How to properly lay ondulin so that the roof does not leak, details in the video:

When installing ventilation outlets through the roofing, you can use special outlets. The base of the structure passing through the roof is attached to all waves bottom sheet, and the top

Choosing material for finishing coating roofs of their houses, many homeowners choose ondulin. This sheet material appeared with us not so long ago; it is a lightweight, durable and environmentally friendly coating, suitable for both new roofs in houses under construction and for replacing old roofs. It is available in the form of wave-shaped sheets or in the form of tile sheets. An advantage is the possibility of installing Euro slate, as ondulin is sometimes called, on top of the old roof, without dismantling it.

Any novice builder without work experience can install ondulin with his own hands. The main thing is that the roof structure is pitched.

The mass of an individual sheet is about 6 kilograms. This makes it easy for one person to work with them, and transportation and unloading will not cause any problems. In order for the installation to be carried out efficiently, it is necessary to follow the instructions and pay attention to the nuances.

Basic information on installing ondulin can be found in the instructions supplied with the purchased material. It clearly and clearly indicates: the distances that must be maintained, maximum length sheet overhang and overlap width. By following the instructions and carrying out all the work exactly, you can be sure that the installed roof will last for many years and will be strong and reliable. It's not difficult at all, just know a few rules.

First stage

This may sound strange, but you need to start work by studying the weather forecast for the coming days. To carry out high-quality installation of ondulin, it is necessary that the temperature outside does not rise above 30 degrees Celsius. During the heat, when the air temperature exceeds 30 degrees, ondulin becomes too soft, which creates serious inconvenience for installation, and the performer runs the risk of getting sunstroke or heatstroke in such heat.

For marking such a roof, a regular ruler will not work; it will be difficult for it to mark wavy material. It is recommended to take part of a sheet of ondulin, preferably a different color, and, laying it wave on wave, use a colored marker to make the necessary marks.

Nuances of fastening and laying out sheets

According to the project, it is necessary to mark the locations of the fasteners on each sheet of ondulin; they are located at the top point of the wave, according to a strict plan with a fixed pitch. These places must be measured very carefully. The number of nails needed is approximately 20-25 units per whole sheet. Otherwise, there is a high chance that powerful gusts of wind could tear off a poorly secured sheet. This rule is reflected in the instructions for attaching ondulin and is mandatory. The nails must be driven in so that the head is slightly recessed, but the main thing is not to overdo it and be careful not to damage the coating.

Cutting a sheet of ondulin in the transverse direction is easily done using a regular wood saw. To prevent bitumen from sticking to the teeth and make cutting easier, it is recommended to moisten the blade with water. It will be more effective to lubricate the saw with oil or silicone grease. To make cutting easier, you can use a jigsaw.

You can cut sheets along the wave using a sharp construction knife. The sheets are laid out on the roof in a checkerboard pattern, and be sure to use a level for control. Fastening begins from the lower corner of the roof slope located on the leeward side. It is imperative to ensure that no junction of four is formed in any place on the roof. various sheets ondulina. To avoid this situation and implement a checkerboard layout, you need to start each new even row with half of a whole sheet.

If the sheet has not been secured correctly, it cannot be reinstalled. It becomes deformed and holes remain for fasteners. Such a sheet is considered damaged, it must be thrown away and a new one taken.

Ondulin is a fairly elastic material. When installing it, do not apply force; this may lead to its deformation. A situation often arises when a couple of centimeters remain to the edge of the roof; in such cases, it is necessary to add a new sheet rather than stretch the penultimate one. If the sheet is held in tension, after some time it will begin to deform.

It happens that during roof installation it is necessary to move along an already fixed covering. To avoid damage to the sheets, it is necessary to step on the top of the wave, and not into the depressions. To be on the safe side, it is better to place the board on several waves.

Rules for calculating the number of ondulin sheets

Calculating the required amount of ondulin is quite simple. If you don’t want to do the calculations yourself, you can use online calculations. To do this, you need to know the dimensions of the roof. You can roughly estimate the amount of material needed for installation yourself. To do this, you need to calculate the total area of ​​​​all roof elements, add them up, and divide the resulting result by the area of ​​the sheet used, minus the overlaps and overlaps. The adjustment for waste is about 15 percent. The amount of waste depends on the complexity of the roof; the more complex it is, the more there will be.

Installation of sheathing for laying ondulin is considered mandatory. This material is plastic and can change shape when heated. For sheathing, a 50 by 40 beam is recommended, which is attached to the rafters, forming a lattice structure. The pitch of the required sheathing directly depends on the slope of the roof or its individual elements. If the angle of inclination is less than 11 degrees, you need to construct a continuous sheathing using boards, plywood or OSB boards. When the slope of the roof elements is in the range from 11 to 16 degrees, the gap between the sheathing beams is maintained no more than 45 cm. Steep slopes, roof angles of 16 degrees or more are equipped with sheathing in increments of 60 cm.

Advice! To be on the safe side, you can perform a continuous sheathing, regardless of the slope of the roof elements. This guarantees the absence of deformation and sagging of ondulin sheets.

Any operation must be controlled using a plumb line and level. It is not necessary to install insulation or waterproofing under ondulin, this is only at will. Laying sheet material begins with a starting strip.

Markings for fasteners must be made so that the holes are located above the sheathing beams. If the roof geometry suggests the construction complex elements, it is necessary to draw a diagram of the layout of the sheets and number them. Installation must be carried out according to the drawn up diagram.

Rules for fastening sheet material

In order for the roof to be reliable and last for many years, you must strictly follow the instructions for installing ondulin. The first sheet is mounted in the lower corner. It is selected by calculating the most characteristic wind direction, and installation begins from the opposite side. This will ensure that the covering wave has no disruptive force.

Due to the tendency of ondulin to soften from heat and become brittle in the cold, the sheets must be laid out in a fixed temperature range.

Installation is carried out at outside air temperatures from 3 to 29 degrees Celsius. This allows you to avoid cracks or breaks at sub-zero temperatures, as well as stretching and deformation in heat.

If you need to replace several sheets urgently, but the temperature does not allow it, you can carry out the work by preparing holes for fasteners in advance, and carry out all actions very carefully.

To speed up the installation process and save material, some people attach stretched sheets. During temperature changes, these sheets become deformed, and to eliminate the consequences, the entire roof will need to be re-covered.

The ease and quality of installation depends on correct installation starting sheet, since subsequent ones largely fit on it. It must be aligned with the edge of the roof end and the eaves. The protrusion of the ondulin sheet beyond the cornice should not exceed 40-50 cm. Exceeding this parameter can cause the sheet to sag, which will spoil appearance. The final fastening of each sheet is carried out after a thorough level check.

Preparatory work for marking and cutting sheets must be carried out on the ground. After this, numbering is carried out according to the installation plan. After this, work on the roof begins, strictly adhering to the scheme.

During roof installation work with ondulin, the following values ​​are maintained:

  • when the angle of inclination of the roof parts is no more than 11 degrees, adjacent sheets are laid with a longitudinal overlap the width of two waves, and the transverse overlap is 19 cm;
  • if the roof slopes are located with a slope of 11 to 16 degrees, then the longitudinal overlap is reduced to the width of one wave, and the transverse overlap will accordingly be 15 cm;
  • Also, overlap in the width of one wave is used on roofs and its elements with a slope of 16 degrees, and the transverse one is reduced to 12 cm.

Rules and elements of fixation

A special type of fastener is used - a nail with a head, which, after driving it into the sheathing, closes and protects the metal from exposure to the atmosphere, thereby preventing corrosion.

Appeared not long ago the new kind fasteners - special hardware for fixing ondulin with a reinforced plastic closed cap.

When choosing a roof covering, pay attention to ondulin, which modern construction used as soft roof. This roofing material, in addition to its good price-quality ratio, will pleasantly surprise you with other undeniable advantages. Ondulin is easy to install, has a long service life, and is environmentally friendly. Proper installation of this material will allow long years Don’t think about the need to repair your roof.

How can you use ondulin to cover a roof?

Ondulin can be classified as a universal material that combines both lightness (the weight of a sheet with an area of ​​1.9 m2 is only 6.5 kg) and strength, the ability to withstand a load of 300 kg/m2. The technology for laying ondulin on the roof surface offers several options:

  • On old roofing without dismantling it. It is allowed to lay ondulin on the roof if the rafters, beams and other structural elements the roofs are in satisfactory condition and do not need replacement;
  • On a roof covered with roofing felt. Before installation, it is necessary to check the integrity of the old coating and repair damage;
  • On the roof of a built house or other structure.

Important! The main and most important thing in laying ondulin is compliance with the manufacturer’s instructions listed in the instructions, which are usually attached to the roofing material. The quality of the coating directly depends on the correct installation and adherence to technology.

In the case of laying ondulin on an old roof, a new sheathing is made, before this it is necessary to lay and strengthen a vapor barrier, it is better to glue the insulation joints with mounting tape. If necessary, thermal insulation is also carried out, and then old roof Ondulin is installed according to the usual scheme.

If ondulin is mounted on a roofing material covering, it is necessary to carefully repair all damage, seal cracks, after which a counter-lattice is installed on the roof along the rafters and the lathing is perpendicular to the location of the rafter system. This implementation of the lathing will allow moisture and condensation to evaporate from the surface of the roofing felt covering. After this, ondulin is laid on the sheathing according to the usual pattern.

When installing ondulin on a new roof, a high-quality sheathing, vapor barrier, and, if desired, insulation of the roof are first performed. After this, the roofing material is attached.

Features of laying ondulin

In order for the roofing covering to serve for a long time, it is necessary to follow the rules for laying ondulin recommended by the manufacturer of the material.

When installing and laying, be careful when combining roofing materials. If an error is made during installation and the nailed sheet has to be dismantled, it is no longer suitable for reuse and will have to be thrown away and replaced with a new one.

Ondulin has elasticity; if you apply some effort, it can be stretched, especially at elevated air temperatures. Under no circumstances should this be done during installation; care must be taken to ensure that the sheets do not stretch before securing them. Otherwise, after the temperature drops, the ondulin will return to its previous size, and rigid fixation on the roof will lead to a violation of the integrity of the roof, the coating may warp, crack, and you will have to replace individual sections with new material and repair the roof.

Advice! If you need to walk on a roof covered with ondulin, step on the crests of the waves, otherwise the roofing covering may be damaged.

Selecting weather conditions

First of all, before performing roofing work, you need to choose the right weather conditions, namely, the air temperature should be in the range from 0 o C to 30 o C. If the temperature environment will be below zero, the fragility of ondulin increases, it may crack or break during installation. At extreme high temperatures air, ondulin can be deformed and stretched if laid under such conditions; after cooling, the material will begin to return to its previous dimensions, which will lead to the appearance of cracks and deformations.

How to cut ondulin correctly

When installing the roofing, you will have to cut the ondulin sheets. Can be used for cutting regular saw with small teeth. Before use and during operation, it is better to lubricate the saw blade with machine oil or liquid silicone. You can use a power saw or jigsaw. In some cases, if you need to cut along the wave, you can use a sharp construction knife.

How to properly secure ondulin sheets

To secure the ondulin coating to the roof surface, it is necessary to use a sufficient number of special nails. It is recommended to hammer at least 20 nails onto each sheet, otherwise, if the fastening is not reliable enough, strong wind loosely secured elements can simply be carried away from the roof.

The head of the nail should be slightly recessed into the roofing, but if you apply excessive force, you may break or damage the roofing material.

The fastenings must be placed strictly in the marked places; they must be located at the same level on each sheet of roofing. To ensure that the fastenings are on the same line, you can use a cord or fishing line to guide you when driving nails into the ondulin.

How to choose the right lathing

It is necessary to attach the ondulin coating to a pre-mounted sheathing of beams. The manufacturing option for the sheathing depends on the angle of the roof:

  • If the roof has a slope of up to 10°, a continuous version of the sheathing is performed;
  • With a slope of 10-15 o, sheathing is allowed in increments of 45 cm;
  • If the roof has a slope of more than 15°, then lathing is done in increments of 60 cm.

Since ondulin has good sound-proofing properties, additional sound insulation is not required (unlike a metal roof).

How to properly install ondulin on the roof surface

It is necessary to start laying on the leeward side, otherwise your coating may fly away in a strong hurricane wind. If the roof has complex design or a lot various elements, you can first mark the sheets on the ground, number them, and then lift them up and secure them to the roof.

The sheets are fixed to the sheathing, aligned horizontally and vertically, and then fixed with special nails. Each subsequent sheet of ondulin should be laid overlapping the previous one.

The ondulin laying scheme assumes that the sheets are laid on the roof with offsets in adjacent rows. If the first row began with a whole sheet, then start the remaining odd rows with a whole sheet, and the second and subsequent even rows with half of the slate, cut lengthwise. Thus, at the joints, a maximum of three sheets will be connected; when laying, it is impossible to allow four layers of coating to converge in places of overlap, this will reduce the quality and lead to warping of the material, as advised in the roofing lessons on video.

It is important to comply required size overlap. The amount of overlap depends on the size of the roof slope. The smaller the angle of inclination, the greater the overlap. On a roof with an inclination angle of up to 10°, an overlap is made in two waves in horizontal rows and up to 30 cm vertically.

If the angle of the roof is more than 15°, then an overlap of one wave and 15-20 cm along the length of the sheet is sufficient.

It is also important to properly fasten the sheets to the roof. It is better to mark places for fastening nails in advance. It is recommended to use 20 nails per sheet of material. The bottom of the sheet is nailed on each wave using half the nails. The second half is distributed over the middle and upper part of the sheet, nailing through one wave, resulting in a zigzag line. To maintain an even line along which the fasteners need to be made, you can tighten the cord or fishing line.

The overhang from the roof should not be too large, about 5-7 cm. If the length of the overhang is longer, the ondulin may be deformed; with a smaller size, snow or rainwater may be blown under the roof.

After fixing the entire ondulin covering, the ridge element is installed, and special wind strips are also fixed.

Conclusion

Today, ondulin occupies one of the first positions in popularity among roofing materials, especially for country and country buildings. Due to its light weight, one person can lay such a coating. The main difficulty of roofing work lies in the exact implementation of the manufacturer’s recommendations when arranging the lathing, laying and fastening ondulin on the roof.
