Tesovaya roof and everything about it

Testo roof - advantages and disadvantages, styling features

There are quite a few varieties of material for roofing ... The option is chosen depending on what is the style of the building, its direct purpose, what are the weather conditions and ecology in the area.

The tessellated roof has become a real example of a successful combination of environmental friendliness and modern technologies, as well as a time-tested material - wood.

What is a plank roof

When cutting logs longitudinally, edged boards are obtained, which have the same thickness along the entire length. Plank edges need to be trimmed to make the material more convenient and uniform for laying. This type of lumber is called plank. A plank roof is usually made of such boards, which are laid in 1-2 layers.

The roof structure is quite simple, its installation does not require any special efforts, but some special skills.

At the same time, the appearance of the roofs is great. This option is perfect for buildings that are built in rustic style, chalet, rustic or even hunting style. Even more often this option is used when building buildings for household purposes.

Wood is a very light, beautiful material with excellent thermal insulation qualities. But consider the fact that the tree does not tolerate the effects of snow, rain and sun very well.

Tesovye types of roofs need regular, one might say relatively frequent repairs, as well as maintenance - boards should be treated with antiseptics or painted. On the other hand, with such a device, it is not difficult to repair the roof: at any time you can replace the affected fungal colony or cracked board with a new one. Tesovye types of roofs look unusual, to some extent even original. But it is worth using this material for log buildings that are built of wooden bricks or timber.

Advantages and disadvantages of a plank roof

This type of roof has many advantages.

They are connected both with the material of manufacture and with the laying technology:

1. Wood has the maximum high quality thermal insulation among all building materials of natural origin - a roof made of edged boards will guarantee warmth in the winter, as well as a pleasant coolness in the summer.
2. Wood has truly unique qualities in terms of climate regulation - with a high degree of humidity inside the room, the wood begins to absorb moisture and remove it outside, and if the humidity inside the building drops, the tree will replenish it, and thereby create a healthy , pleasant microclimate - such a roof fully possesses this advantage.
3. Tes has excellent qualities in terms of sound insulation, because such a roof is a way to "dampen" the noise of wind, rain and hail.
4. Wood is a 100% environmentally friendly material that poses no danger to the environment.
5. The price for a plank roof is minimal - edged boards, even from relatively expensive species, are the most affordable material for roofing.

6. In addition, the tessellation is lightweight even at incredibly large dimensions, which means that installing the roofing material does not take much time, and the roof itself does not put a lot of stress on the base.
7. The appearance is quite interesting, and it is an important advantage - after a while the boards begin to darken, and a wooden building with a plank roof takes on a beautiful, even somewhat authentic look.

But it would be unfair to say that even such an excellent material has no drawbacks:

1. The material can be confidently called fire hazardous, and the boards must be processed before laying with fire retardants , although this only reduces the ability to ignite, but does not help in any way to eliminate the risk of spontaneous combustion of wood.
2. Lumber needs protection from fungi, mold, bark beetles, and the boards are processed not just before installation, but also every 3 years of the operational period.
3. Consider the fact that wood, as a building and roofing material, is prone to shrinkage, and in the first years the wood shrinks by 10% and nothing less - this factor must be taken into account when installing boards.

4. Roofing repairs will need to be carried out every 5 years.

Roofing maintenance is simple and does not require any special knowledge. The responsibility of monitoring the integrity of the material and replacing deformed boards does not greatly burden the owners of a wooden building.

Material of manufacture

It is important to choose edged types of boards for a board roof taking into account certain parameters, and we will consider them in more detail. For a plank roof, boards are needed that are made of conifers.

This type of wood contains more resins, and the latter will completely protect the material from moisture:

• The simplest and most affordable option can be safely called pine boards, because it is pine boards that do not warp, are resistant to fungal infections, but at the same time they need regular treatment with antimicrobial compounds, because they are prone to rotting.
• According to user characteristics, spruce is close to pine, but at the same time it is more resistant to moisture.
• Cedar is no less beautiful, and for this reason cedar boards will be more expensive than the first two materials, but they have bactericidal properties and are quite durable.
• The best material for a roof is larch, because such wood is not afraid of snow, rain or sun, and after a while it becomes only stronger and harder, larch boards have almost no spots and knots, very beautiful and serve exceptionally long, but larch boards are the most expensive.

The technical parameters of the boards must also correspond to certain characteristics:

• Boards for roofing from a plank should be made only of dry wood, this will cause shrinkage of the material, but it guarantees a great degree of durability.

• The board must necessarily correspond to the length of the slope, and at the same time it is required to take into account that the slope at the board roof must have a slope of at least 28 degrees in order to ensure water drainage, and they can be 4-6 in length. 5 meters.
• The thickness of the cutting board varies and is 1. 9-4 cm, and the width is 16-25 cm. We do not recommend using lumber with a width of more than 0.

  2 meters for the manufacture, because such boards are more prone to warping and drying out in the sun.

• On one side of the boards, a groove is made along the total length, and this is how it turns out to ensure the drainage of water, while it is important to take into account that when laying in layers, it is important to alternate the boards (the lower boards are fixed with the core down, and the upper ones with the core up, in the photo you can see just such a roof).
• Boards must necessarily be planed on four sides, and this is extremely important, because boards, which are planed on only three sides, are much worse for processing with fungicides and fire retardants, which will significantly affect their quality.

Please note that roofing felt or the simplest polyethylene film should not be used for waterproofing such a roof.

To prevent condensation, it will be necessary to install in such a way that there is a gap for ventilation between the film and the plate.

In order not to complicate the structure, it is best to use new waterproofing materials that allow steam to pass from the inside of the attic.

The technology of installation of a plank roof

The roof structure is really quite simple. But even here there are many features that are important to consider so that the roof serves as long as possible and does not need to be constantly repaired. The first of these requirements can be called the treatment of boards with fungicides and fire retardants, because otherwise the roof will not last so long.

Laying methods

There are several methods of laying the timber, and the choice will depend on the purpose of the building - residential building, utility building, and also on the climatic conditions of the region.

The roof can be two-layer, three-layer and even four-layer. At the same time, the offset does not become less - with a three-layer installation, each new row is attached with an offset of 2/3 of the entire length, with a four-layer one with mixing by 3/4 of the total length.

Installation technology

Roofs made of wood are fairly simple structures, and it requires more accuracy than skills to build such a roof ...

1. It is required to calculate the required amount of material, taking into account the selected installation method.To do this, first it is important to determine the number of boards in a row - divide the width of the slope by the width of the board, and then find out the number of rows - for this model, the length of the slope by the length of the board. Multiply the obtained values, and you get the number of tesa per row. If you are planning a two-layer end-to-end installation, multiply the resulting value by 2 and add 10%, taking into account the possible marriage or damage during work.
2. On the rafters, fix a waterproofing film, preferably a vapor barrier.

3. On top of the film, you need to equip a crate of wooden blocks with a size of 5 * 5 cm. The slats are laid across the slope if it is assumed that the laying will be longitudinal. The lathing will provide a ventilation gap between the board and the waterproofing layer.
4. Tesa boards must be laid according to the chosen method of roof arrangement and secured with self-tapping screws in increments of 0.5 meters.

   Then install the second layer, and if necessary, then the third.

5. After installing the board, the ridge is waterproofed with roofing felt, a ridge board is attached, and for protection from above, install a steel corner.

The transverse type of laying does not require the installation of the lathing, because the rafter system itself acts as a completely suitable base. But in this case, waterproofing can only be done using a vapor barrier membrane.

Features for the care of the roof

Correctly caring for a wooden roof is not difficult and basically comes down to regular inspection, as well as elimination of defects:

• In spring, the roof must be cleared of snow before the melting begins, because otherwise the risk of roof leaks and excessive swelling of the tree increases.

• Defects found during inspection must be eliminated immediately, cracks and resins are important to seal with putty. If the roof is already painted, then the putty must be mixed with the same paint in advance, and after drying, everything is also painted.
• If the roof, which is made of wood, is covered with bitumen, then cracks must be filled with a mixture of chalk and bitumen.
• Once every 3 years, it is required to process the dough with fire retardants and fungicides.
• If during inspection you find rotten boards, it is important to replace them immediately.

Please note that a plank roof can last up to 15 years if it is properly operated and regular maintenance and minor repairs are carried out.

Conclusion

A roof made of tessellation has become an affordable and simple roof option. Edged boards provide excellent thermal insulation, have a beautiful appearance and an equally attractive price. But this option is not the most durable and requires some care.
