Slate and ondulin - user reviews Ondulin or slate - which is better for the roof

There are many offers on the roofing materials market, and to understand such a variety is extremely difficult, for example, which is better, slate or ondulin, or shingle roofing against metal tiles. In order to assess the advantages and disadvantages of such materials, you will need to thoroughly delve into their qualities and properties, and even better to compare slate or ondulin based on reviews and results of practical application.

Before trying to compare both types of roofing coatings, looking for the best sides and disadvantages in each of them, you need to understand what ondulin and slate are.

Slate and ondulin - what are they?


A couple of features can be noted that unite both materials :

  • Wavy surface of the coating - due to the presence of a wave, the slate surface, and even more so ondulin, receives rigidity and is much better than metal tiles or profiled metals, withstand snow pressure, wind gusts and rain.
  • Large material thickness, from 0.

    4 to 0.6 cm. The roof has a lower level of thermal conductivity, retains heat much better and is almost impervious to condensation.

Please note that although both ondulin and slate are not prone to condensation, due to the presence of free space under all waves, it will be much better ventilated and dried than metal roofs.

This is where the general properties and qualities of ondulin and slate ended, but otherwise they are completely different materials, and therefore, in order to better understand the difference, it is required to turn to the technology of creating two types of coating.

Which is better, slate or ondulin

Slate is a non-standard roofing coating that is not prone to rotting, degradation, drying out or deformation due to temperatures. In the form in which it is used today, the wave slate sheet has existed since 1901, from the moment the plant of Ludwig Gatchek (Austrian) was launched, and no one has been able to do a better one, although there have been a lot of attempts to improve the slate. It is difficult to compare both types of roofing, because they are related only by the structure of the wavy type. Everything else, from strength parameters to material, is completely different, and therefore it is better to make a comparison based on practical feedback in the main three categories:

  • Reliability, service life and roofing resistance.
  • The appearance of the decorative coating and its durability.

  • Repair, installation and operational period.

Despite the external similarity, ondulin and slate are not interchangeable. Due to the large difference in weight, for the construction of rafters and roof sheathing, it is required to use more massive boards and beams.

Good advice! If you are not completely sure to prefer ondulin or slate, then it is better to plan a roof under a sheet of asbestos cement.

That is, it will not be difficult to overlap the frame after the slate, but it will be much more difficult to lay asbestos-cement sheets on the surface of the crate from under the ondulin.



Slate and ondulin - user reviews Laying slate on the roof is not just difficult, but very difficult. Moreover, the slate sheets are 4 times heavier than ondulin, and the material is also very fragile, and a special suspension or flooring is required to drag uncomfortable sheets of asbestos cement onto the roof lathing.

When planning the installation of slate on the roof, you should definitely stock up on at least one sheet in reserve. An ondulin roof, regardless of size and roof height, can be easily covered even alone. Lifting and stacking sheets of material is easy because the weight is only 6 kg.

On the other hand, a special type of lathing is important for ondulin, and as a rule, the rafters are sewn up solidly with plywood or unedged boards.

For the installation of slate, the crate step should be 2 times higher, and it is required to beat it on specially fixed slats. Nails for fixing the roof from slate will take 3 times less than ondulin.

Materials are sometimes compared in terms of ease of cutting and drilling. Which is better for the roof, ondulin or slate? In this case, definitely ondulin.

A simple jigsaw can be used to cut the cellulose sheets, while the cement-asbestos material needs to be cut with an angle grinder using water.

By the properties of operation

Most of the owners give preference to building the roof in the expectation that it will not be necessary to maintain the roof covering at all, or a minimum amount of time can be spent on maintaining it ... In this regard, ondulin is again better than slate.

On the roof under the ondulin, you can climb a roof ladder or staircase, clean and even paint the surfaces without any particular risks of damage to the coating. Slate must be handled with maximum care, before moving on a slate roof, it is required to lay floorings, and use scaffolding or stairs to work on eaves or overhangs. As the reviews say, slate is highly resistant to negative factors.

Slate roof easily withstands almost all thermal, static loads, temperature fluctuations, air humidity, without deformation and sagging. A high-quality slate sheet, which is laid on soft ground, is able to withstand the weight of an adult, and therefore slate is best suited for northern latitudes with a large amount of precipitation in the form of snow.

For a cool and humid climate, a slate roof is better than an ondulin roof, although it will need to be swept away fungal thickets and moss from it every few years. In this sense, it is much easier to clean an asbestos-cement roof. It is enough just to borrow or purchase a high pressure washer, and in 2-3 hours with the help of a powerful water jet, clean the surface almost white, as in the video.

In appearance

The texture of the striped type and the gray color of the slate roof have always been important arguments against asbestos cement, and therefore the roof is painted with special paints and varnishes. for which it is almost impossible to distinguish slate from ondulin.

Ondulin roofs in 7 different colors and shades are actively used for indoor playgrounds and gazebos. It is believed that in addition to its beautiful appearance, such a roof is safer in terms of environmental friendliness.

By service life

It makes no sense to compare onduline and slate sheets by service life. A roof made of asbestos cement, with proper care, can stand on a high-quality rafter frame for 75-80 years. You will only need to check the integrity of the nails and clean and repaint the roof once every 10 years.

Ondulin, even the best one, is able to "live" on the roof for a maximum of 10 years, and after that the roof covering begins to bend, the nails are ejected and the canvas breaks. One of the options for using a cellulose sheet as a roof is shown in the video.

How to make the right choice

Each material is good in its own way, and therefore choosing which is better is required based on the purpose of the building and the availability of resources:

  • Slate and ondulin - user reviews For residential buildings with a gable insulated roof, slate is best suited; for frame buildings of country cottages, ondulin can be used, but with an additional filing the lathing and a reduced step of the control lathing.
  • For temporary sheds, gazebos, cool sheds and other similar buildings where there is no heating system, it is possible and important to use ondulin. As practice has shown, such buildings serve no more than 15 years, which coincides with the life of the ondulin roof.

One exception to the rule would be to build a canopy or roof in the sun, especially in hot climates. Under conditions of powerful radiation from the Sun, binding components and impregnations begin to rapidly degrade, decompose and evaporate, which will lead to roof destruction. In this case, slate or metal tiles should be installed.

Slate or ondulin (reviews)

Gordey Andreevich, 41 years old, Volgodonsk: "Ondulina has gone on my roof for the second decade already. We have a hot area, and because in the summer I often water the roof with a hose, and there is less dust, and there is no smell.

The neighbor had slate, he also watered it, but because of this, the rafters led and the sheets rose, somewhere even burst. There is nothing better than ondulin ".

Anatoly Sergeevich, 66 years old, Volgograd: “I covered my dacha house with ondulin long ago, and 2 years ago there was a storm, a tree broke nearby, a branch punched through the roof and even one leaf was ripped off. With a neighbor, we were able to repair everything in a day, he said that if there was slate, then half of the roof would have to be changed. "

Arsen Viktorovich, 63 years old, Naberezhnye Chelny: "For my climate, slate is better, because although ondulin is cheaper, it rots like wood.

If the house is by the river, then the roof will deteriorate in a couple of years, and nails, wind and cornice strips will not help here. Nothing has been invented better than heavy slate for the winter period or downpours, even metal tiles lose to it in terms of durability. "

Alexander Artemovich, 43 years old, Balashikha:" You can cover the roof with both slate and ondulin, no a big difference if the master does everything. Ondulin is better for me because it is cheap, and you can also make a lot of things from it on the farm, for example, cover the greenhouse. It is more difficult with slate, but it is also used for large and serious houses.



It is difficult to choose which is better - ondulin or slate for beginners who have not previously encountered the process of building a full-fledged roof.In spite of the fact that slate began to be produced less due to problems with asbestos, the demand for roofing sheets has not decreased, which means that the material is worthy.Ondulin is relatively young, it is actively used in construction for more than 45 years, and so far there are no advantages for which it would be possible to abandon metal or slate roofing in favor of pressed cellulose.
