Many forms of roofs in modern houses surprise with their appearance. The pitched type of roof is checked by the use for many decades, it is ideal under the weather conditions characteristic of our country. In addition, specialists in design and installation are trying to give suburban houses the appearance of presentable and modern construction sites. The space located under the roof slop is used for housing, attic or attic, and maybe it is also equipped under the rest room.
Rafters – the main element of the roof
The creation of structures from rafter elements in direct depends on the variety of roofing materials that have to cover the roof. For example, under natural tiles, the creation of an enhanced configuration is required, since weighing the finished structure will be much larger than other analogues. In addition, it is necessary to take into account the material of the crate, which is to be done in the future, at this stage the accuracy of the work is important.
The inclined variety of rafters has a resemblance to the rafter legs, one end of which rests on Mauerlat, and the other on the run. From the sideboard, this design has the shape of a triangle. When performing the calculation of the structure, it is necessary to take into account the nature of weather phenomena – precipitation, wind.
A hanging variety of rafters is a farm located perpendicular to the walls of a wooden structure and parallel to each other. Farms have the shape of rods from rods and are located in one plane.
The main material used for rafter elements is pine. But sometimes construction companies use metal or reinforced concrete products, the section size of which is 50×150 millimeters.
Installation of a pitched overlap
The crate is attached to the rafters, selected depending on the materials used for the overlap. All layers of roofing are laid on it. Perhaps it is difficult to figure out all the intricacies of installation, but it is on this that all thermal characteristics of the house depend on.
At the next stage, the insulation is laid – cotton wool or fiberglass. These materials help maintain heat. Insulating plates for 20-30 millimeters should be greater than the distance between the rafters, which helps to fix them reliably and with the desired tension.
A vapor barrier material is applied on top of the insulation, which prevents condensation to the surface of the roof, preventing it from decaying.
Strengthening all roofing elements should be performed in some cases for this, galvanized nails are used. It is not worth saving on fasteners, since the life of the roof of the house depends on it.
