The roof is the most important element of any home, because it is designed to protect the room from the effects of atmospheric phenomena. When it comes to the roof of a private house, then, in addition to reliability, its appearance is of great importance. Property owners are trying to choose a versatile, aesthetic and durable coating. Euroslate (ondulin) meets all these requirements. Its installation is quite simple, and the material itself has excellent performance characteristics, which make it quite in demand and popular both in the CIS countries and in Europe.
Why is ondulin so good, what is it made of and how difficult is its installation? These and many other issues related to this type of roof, we will consider in this article.
What is euroslate and how is it made
Probably, every owner of a private house, before purchasing this or that roofing, will take an interest in its characteristics andthe material from which it is made. Many will be surprised, but the main raw material used in the production of ondulin is ordinary pressed waste paper.
Various mineral fillers and synthetic resins with coloring pigments are added to the cleaned paper waste. The resulting sheets are impregnated with bitumen under high pressure, which makes them sufficiently strong and resistant to atmospheric agents.
Main characteristics of the material
In appearance, bituminous sheets are very similar to ordinary slate, but if you look at their technical characteristics, you can notice a number of differences. Namely:
1. Ondulin is considered one of the most fire hazardous roofing materials. Laying it can be carried out exclusively on a non-combustible base. At temperatures above 250 degrees, the bituminous coating ignites quickly, making it impossible to use it on the roofs of schools, kindergartens, clinics and other public institutions.
2. Unlike slate, the weight of one sheet of ondulin does not exceed 6.5 kilograms. This feature allows us to classify euroslate as the lightest materials that do not exert a large load on the truss system. Laying ondulin on the roof can be done with your own hands, without special equipment and a large number of assistants. Transportation of the material is also not expensive, as the sheets can be delivered to the site using your own car.
3. Ondulin, the laying of which is discussed in detail in thisarticle, is able to withstand heavy physical exertion (960 kgf / sq. M). Such a roof is not subject to deformation, is resistant to strong gusts of wind and does not lose strength under the influence of frost and large layers of snow.
Sheet specifications
In order to correctly calculate ondulin (determine the required amount of material), you should pay attention to the dimensions of one sheet. Today, manufacturers produce products in the following sizes:
• The length of one sheet is 2000mm;
• the width of each element is 960mm;
• sheet thickness is within 2.8-3.2mm;
• wave pitch is 95mm;
• wave height - 36 mm;
• There are 10 waves on one sheet;
• The useful area of one element depends on the angle of the roof and can be 1.29/1.54/1.56 meters.
Colours
The color range of euroslate can hardly be called extensive. Most often on trading floors you can find red, green, black and brown ondulin. The colors are mostly muted, but on the roofs of the houses the material looks very attractive. The presence of a small number of shades does not interfere at all with choosing a roof that will be successfully combined with the facade of the house and additional buildings.
When choosing euroslate, do not focus only on the color of the sheet, pay special attention to product quality and the reliability of the manufacturer. For comparison, check out several samples of soft roofing at the same time.
You should not give preference to too cheap products, because if the price is prohibitively low, it means that the manufacturer saved on something. Often these savings are reflected directly in the quality of the material and its service life.
Today there are many stores where you can buy high-quality ondulin ("Leroy Merlin", "Castorama", "Maxidom", OBI, etc.). They offer a huge range of bituminous roofing from different manufacturers. In large retail chains, you can find products of all possible colors, in addition, large stores value their name very much and try to sell only certified goods of good quality. Therefore, if you want to purchase high-quality ondulin, Leroy Merlin and similar stores visit first.
Euroslate cost
Covering the roof with bituminous sheets is a cost-effective solution. Ondulin manufacturers give a 15-year warranty on their products. However, practice shows that with strict adherence to the installation technology and proper operation, such a roof can last more than five decades. Therefore, we can safely say that the cost of purchasing euroslate is fully justified.
If we talk about specific figures, then the average price for ondulin today varies between 350-500 rubles.
The following factors also affect the final amount:
1. Order volume. For wholesale buyers, the price is usually slightly reduced.
2. Remotenessenterprises producing bituminous roofing. The cost of shipping the material (from the manufacturer to the supplier) is always included in the cost of the product itself.
3. The shade in which ondulin is painted. Sheet colors have a direct impact on the final cost. This is due to the fact that expensive dyeing technologies are used to make multi-colored euroslate.
Remember: in addition to the main roofing material, you will need various accessories (horse, valley, tong, covering the apron, cornice seal, etc.). Their cost must also be included in the estimate. Do not forget about nails for ondulin. It should be noted that they differ from ordinary slate nails, so we will focus on their choice separately.
Fastening for euroslate
Special nails for ondulin are distinguished by the presence of hats made of polypropylene or polyvinyl chloride. It is noteworthy that both of these materials are quite resistant to UV and temperature fluctuations.
Increased caps provide the necessary tightness of the roofing and high reliability of fastening, which are not disturbed even with strong gusts of wind.
The concave shape of the gasket contributes to the tightest fixation of fasteners on the sheet, and the presence of a plastic cap on the cap helps protect the nail from unwanted contact with water.
The metal part of the fastener is made of carbon steel. Its length is usually 70-75 mm, and its diameter is 3.5 mm. The nail itself is covered with a protectivezinc solution, which makes the product resistant to corrosion.
Thanks to the use of special nails, ondulin fastening is of high quality and quite durable.
You will need at least 20 fasteners to lay one sheet.
When all the necessary materials have already been purchased, you can proceed with their installation. Those who plan to hire professional roofers should be aware that their services will cost from 700-800 rubles per m². Nevertheless, experienced specialists will quickly and efficiently lay ondulin. Do-it-yourself laying will help you avoid additional costs, but we will consider how to do this work yourself further in our article.
Preparing the base
Laying ondulin on the roof begins with the preparation of the base, which is a wooden crate. Most often, its pitch is 45 cm, however, depending on the angle of the roof, this distance can be adjusted. So, let's look at what criteria determine the step with which the crate for ondulin will be installed.
1. If the slope of the rafters is less than 10 degrees, a solid base of plywood, boards or OSB boards should be installed. In this case, euroslate sheets are overlapped in 2 waves. The top slate should overlap the bottom one by 30 cm. These recommendations should be taken into account for those who cannot figure out how to lay ondulin on a pitched roof. This laying method is more often used on non-residential buildings.
2. If the angle of inclination is between 10 and15 degrees, the crate for ondulin is installed in increments of 45 cm. The structure itself is assembled from bars 5 x 5 cm or 4 x 6 cm. The sheets overlap the previous ones by 1 wave, and overlap each other by 20 cm in length.
3. In cases where the angle of inclination exceeds 15 degrees, the crate pitch is approximately 60 cm. The wave overlap is performed on one wave, and the vertical overlap will be 17 cm.
4. If there are any roundings on the roof, the crate is equipped with a more frequent step. This is necessary so that in these places the material can normally withstand various loads.
You should also pay attention to the recommendations of the manufacturer who made the ondulin. The installation instructions in the package usually indicate the maximum possible and minimum allowable batten spacing.
Please note that the installation of the crate must be carried out at a temperature of at least 2 degrees, since at lower temperatures the wood tends to split.
Ondulin laying order
During the installation of roofing, you must follow all the rules and recommendations for working with this material. The slightest deviation from the laying technology will lead to a quick failure of the coating, which will lead to additional waste.
Laying ondulin on the roof involves the following work:
1. All material and prepared tools are lifted upstairs.
2. Floor laying starts fromthe edge of the ramp (from its bottom), which is located opposite the windy side.
3. The first row is mounted taking into account the overhangs, the second is laid in a checkerboard pattern.
4. When installing the second row, the sheets are positioned so that the corner overlap is formed not by four, but by three sheets. To do this, first, not a whole sheet of ondulin is placed, but half of it.
5. Nails (at a right angle) are driven into the ondulin in the middle of the upper wave. Fasteners are driven into each wave along the bottom edge of the sheet, and the middle part is nailed to the crate in a checkerboard pattern.
6. If in the process of work it becomes necessary to remove a previously hammered nail, for these purposes they take a small wooden block and lay it in a flowing wave. A nail puller rests against it and unnecessary fasteners are carefully removed from the slate.
7. To install the valleys, an additional crate is constructed. The work will be done much faster if you use materials from the same company that made the ondulin.
8. Skate elements are also better to buy original ones. Their installation is carried out from the leeward side. The overlap must be at least 12.5 cm. Fasteners are driven in along all waves of the sheet connecting to the ridge.
9. At the junction of the roof and walls of the house, the material that was used to equip the valleys is laid. The seams are coated with silicone sealant.
10. The design of the tong is made of special tong elements. They are bent and attached to the gable board and the edges of the ondulin sheet.
11. Places of docking of slate with ventilation and chimneypipes are insulated with silicone and closed with a covering apron. Its fastening is carried out on all waves.
Ventilation and tightness of the roof
Ondulin laying technology involves the performance of work aimed at ensuring the tightness of the roof and creating natural ventilation of the roof. These requirements cannot be ignored. Why is it necessary to fulfill them?
Due to the fact that during the operation of the roof, warm air from the house rises, it comes into contact with cold streams, resulting in condensation that settles on the crate. Because of this, the wood begins to rot, loses its strength, and the roof may collapse. That is why it is very important to make ventilation holes that will prevent the accumulation of moisture under the flooring.
They are installed under the lower slope of the roof in the form of a break, which is made from additional elements. It should help to ensure that moisture does not flow onto the walls of the building, but is removed to the places you need.
The tightness of the flooring is created using all the same additional materials. They close the ridge of the roof and the ends of the roof. As a result, moisture should flow in the right direction.
Particular attention should be paid to trimming the corners of the ondulin at the joints. Why do it?
Since euroslate sheets are overlapped, thick seams are formed at their junctions. Snow can penetrate under them, which, under the influence of heat rising from the house, will begin to melt, and water enters under the roofingmaterial.
Cut corners form less thick seams, as a result of which snow will not penetrate under the slate.
Useful tips for installing ondulin
As mentioned earlier, the installation of euroslate is very simple. In the process of work, complex and expensive equipment is not required, it is enough to have a saw, a hammer and a tape measure at hand. Therefore, if you chose onulin as a roofing, laying it will not cause you any particular difficulties.
Before proceeding with the installation of roofing material, each sheet is marked with a colored pencil or marker. This can speed up the process of cutting the desired pieces. In order not to spend a lot of time measuring each sheet, you can cut out a template from the remnants of slate, according to which you can mark up the rest of the elements in the future.
You can cut ondulin with an ordinary hacksaw for wood (with small teeth). If it gets stuck in the roofing material, it should be lubricated with oil. Also for these purposes, you can use a circular or electric saw with carbide tips on the disk.
Ondulin should be laid at a temperature of 0 to 30 degrees. In frosty weather, the material becomes more brittle, there is a high probability of cracks. In extreme heat, the sheets soften and, if they are fixed in this state, the material may crack after cooling.
Move on the stacked sheets should be in shoes with soft soles, stepping only on convex waves.
