The roof rafter system and its features

Absolutely everyone understands that it is the roof - the detail that is the most evidence of the taste of its owner. She is able to decorate the house, emphasize his personality. If it is decided that the roof truss system needs to be completed independently, it is worthwhile to understand that there is nothing heavy in this. But still this design must be installed without any errors. First of all, the rafter system is an engineering structure that protects the house from the influence of the environment. The durability and reliability of the roof construction directly depends on how well the installation is performed.

The main task of the rafter system is to maintain the entire weight of the roof and its reliable protection against wind and snow. Making its calculation, it is necessary to take into account the peculiarities of the location of the house and the type of the chosen roof. In this case, it is worth remembering the margin of strength. Not considering this indicator, you can not start work. The construction of the roof truss system with a certain level of rigidity is achieved by fastening its elements - the frame with the building box. Basically, it is made of wood, as this material has a lot of advantages over the rest.

To fasten the rafters are very often used nails, screws, bolts, yokes and staples. It is worth noting that the first part of this list will not allow to create a reliable and strong fastening, so it is not recommended to use it. Bolts also should not be used as anchorages, because the holes created for them reduce the level of structural stability. The construction of the roof truss system begins with the leveling of the walls. This is done using a screed, which is laid waterproofing layer and Mauerlat. Next, a support sub-string construction is created from racks, runs and struts. Initially, the outer rafters are installed, after which you can place intermediate rafters.

The distance that should be between them depends on the design of the entire system and on the carrying capacity of the crate. For the roof, a so-called pie is used, consisting of four layers: vapor barrier, thermal insulation, waterproofing and roofing material. For a wooden product to be operated for a long time, it must be ensured that it is properly ventilated.

The roof rafter system is built on the construction site near the house and requires a lot of time and labor. The shape and bias of the structure can reduce the list of materials required for the roof.

In addition, the method of installation, the service life and the time of the first repair depend on this. To install the construction of rafters in the construction markets, there are many suitable for the quality and characteristics of materials. In addition, in the selection process should pay attention to their service life. They must be consistent among themselves. In the case where the installation of the rafter system will be performed by a novice, you should think twice before starting to do everything yourself. Alternatively, you can refer to specialists who will make the roof project on request.
