Ondulin as a roofing material has been gaining more and more popularity lately, but a fairly large number of developers know practically nothing about this material and its advantages and disadvantages, as well as about the procedure for laying it.
On the Internet, you can find a large amount of visual aids on how to cover the roof with ondulin - video and photographic materials, this article will talk about what ondulin is and how the roof is covered with it.
Currently, the market offers a fairly wide range of different roofing materials, which include both galvanized and slate, which have long been familiar to everyone, and modern coatings that have come into use only recently, which differ in a much more attractive and original appearance.
Modern roofing material should not only protect the building or structure from precipitation and winds, but also give it a unique appearance, allowing it to differ from neighboring buildings.
One of the most modern soft materials for roofing is ondulin. Knowing how to properly cover the roof with ondulin, you can not only ensure its reliable protection from external influences, but also make it aesthetically attractive, since ondulin is made in the form of light, but strong enough wavy sheets.
The material for the production of ondulin is cellulose or fiberglass impregnated with bitumen and painted in various colors. This article will talk about how to cover the roof with ondulin, and what skills and tools will be required to complete this work.
Ondulin, also called euroslate, is an economical, lightweight, but at the same time reliable material that does not make noise during rain, unlike many other materials, such as Finnish metal tiles. This material has been produced in the USA, Russia and European countries for over 50 years under the Onduline brand, its cost varies depending on the manufacturing plant.
Rules for covering the roof with ondulin
Now let's take a closer look at how to cover the roof with ondulin. This work does not require special skills and tools and may well be done by the owner of the house on their own with certain knowledge.
You can cover the roof with ondulin, adhering to the same rules as when laying ordinary slate. The main difference from laying a coating of asbestos-cement slate is that ondulin has the ability to bend a little, this allows you to lay it not only on flat surfaces, but also on more complex ones.
In the case when we cover the roof with ondulin, laid on top of an existing coating, such as metal, roofing material, flat slate, etc., you can evaluate the rafter system yourself or invite a roofing team.
If, according to the assessment, the truss system of the house is able to withstand additional loads in the form of the weight of the new roof, then the lathing of wood is stuffed over the old roof covering, on which ondulin sheets are fastened, which provides additional hydro and thermal insulation of the roof.
Due to the rather low rigidity of ondulin, the crate for this material should have a fairly frequent step in order to avoid sagging or breakage of the sheets under the influence of external loads such as rainwater and snow cover in winter. For sawing ondulin, you can use an electric jigsaw or a standard hacksaw for wood, pre-lubricated to facilitate the sawing process and prevent the blade from getting stuck.
Detailed instructions for laying ondulin
As already mentioned, the procedure for laying ondulin is similar to the procedure for laying standard slate (this can be seen by watching the videos on the Internet “We cut the roof with ondulin - video”).
Laying instructions are attached to the finished material, compliance with the requirements of which will allow you to better understand how to properly cover the roof with ondulin and prevent various mistakes when laying. The instruction is usually written in an understandable and accessible language, it will not be difficult to understand it even in the absence of special knowledge.
Consider the main nuances of laying ondulin:
-
Proper laying of ondulin sheets The first step is to install a solid timber crate, while taking into account the slope of the roof and the direction of the wind in this area.
Work begins with the corner of the roof least exposed to wind currents. - Bars from which it is made crate for ondulin, are nailed along their axes at equal distances, usually 60-80 centimeters.
- In the case of large distances, additional installation of rails between the bars is carried out to provide additional strength. The slope of the roof must be at least 20.
- The material is laid starting from the lower corner of the roof, the first sheet of the second row should be cut in half lengthwise.
- Ondulin sheets are fastened horizontally using the special nails included in the material kit; twenty nails should be spent on one sheet of coating.
- In the first row of roofing, nails should be nailed to the crest of each sheet wave, in the remaining rows, nails should be driven into every second crest.
- When laying the second row of material, overlap should be made, capturing the sheet laid in the first row, etc. Slate nails for attaching ondulin are made with rubber caps, the color of which matches the color of the coating itself.
Important: nail heads are conspicuous on the surface of the ondulin, therefore, to ensure an attractive appearance of the roof, they should be nailed in one line, which can be achieved by pulling the rope along which the nails are driven.
- Vertically, ondulin sheets are nailed to the beams of the crate, while the transverse overlap is 15 centimeters, and the longitudinal one should not be less than the length of the first wave.
- In the final part of the work, the installation of ridge elements is carried out, which are overlapped and nailed along the wave of the sheet.
- In the case of a gable roof, special corner elements are used for the ridge. The endova for ondulin is made using another crate.
The instruction attached to the ondulin material includes not only information on how to make a roof from ondulin, but also drawings that make this procedure understandable to anyone, regardless of their knowledge and skills. It should also be noted that the size of one sheet of ondulin is 200x95 cm, weight is 5.8 kg, the sheet consists of ten waves, each of which is 36 millimeters high.
Subject to all the rules and requirements listed in the instructions, the service life of the roofing ondulin coating is over 50 years, and the manufacturer's warranty is given for the first 15 years. A hygienic conclusion and a fire certificate are also attached to the warranty card.
Accessories for ondulin
In addition to the ondulin itself as a material, manufacturers have provided for it a number of various accessories made of a similar material, such as:
- Skate element;
- Ondulin valley;
- Gable elements;
- Nails;
- Cornice filler;
- Self-adhesive sealing tape;
- Covering apron;
- Ventilation pipe.
To ensure the greatest efficiency and harmonious appearance of the coating, when laying it, you should use only the original accessories supplied with the material.
Key Benefits of Coating
According to most experts, at the moment ondulin is the most popular type of modern roofing, due to its low cost, ease of installation and good technical performance.
The main positive characteristics of the coating include:
- High reliability provided by impregnation with bitumen, which prevents the absorption of moisture and, accordingly, increased roof waterproofing;
- Ability to withstand a wide range of temperatures from -50 to 50 °, allowing the use of this material in almost any country;
- The ability to withstand the load of snow cover and hurricanes, the speed of which does not exceed 192 m / s;
- Noise absorption and lightning protection;
- Attractive appearance, and the flexibility of the material provides for its installation even on roofs of complex shape.
Ondulin installation cost
To calculate the cost of covering the roof with ondulin, you should calculate the cost of the material itself, depending on the total area of \u200b\u200bthe roof. When going to the store to buy material, you should take a house or roof plan with you so that managers can calculate the required amount of ondulin.
An approximate calculation of the cost of the material can be made independently, for this it is enough to multiply the cost of the material by the total area of \u200b\u200bthe roof to be covered.
It should also be borne in mind that the price of ondulin may decrease depending on the size of the purchased lot. The large dimensions of the sheet make ondulin a fairly profitable material to purchase, and with its independent installation, the cost of roofing will be equal to the cost of the material itself, depending only on the area of \u200b\u200bthe roof.
If, after reading this article and the instructions for ondulin, some questions still remain unclear, you should not take risks and invite a team of specialists to cover the roof.
The relative simplicity makes this work a rather inexpensive service, the cost of which depends more on the professionalism and experience of the workers, as well as on the complexity of the shape of the roof. Also included in the price are factors such as the conditions and timing of the work, as well as the cost of the road to the facility.
