The roof of the house is the upper part of the building and performs functions such as hydraulic and thermal insulation, and is also a supporting part of the building. For any roof, requirements such as strength, reliability, aesthetics and durability are put forward. In order for these requirements to be fulfilled, builders must use modern materials and technologies. The design of the roof consists of such supporting elements as rafters, a Mauerlat, a crate and supplementary elements. Rafts are bearing beams made of wood, which keep not only the weight of the roof, but also withstand the pressure of wind and snow. In their structure, the rafters are divided into hanging, they rely only on the walls of the house, and the layers, which have an intermediate support in the middle part. Mauerlat is a beam or a beam that serves as a support for rafters. It can be laid both around the perimeter of the whole house and in the places of installation of the rafters. Thanks to Mauerlat, the load from the roof is distributed through the walls. The next element in the roof design is the crate. It is made of wood and is located across the rafters. Thus, it serves as the basis for roofing roof material. Then how the crate is made depends on the roofing material. So under a soft roof a continuous crate is used, and under a metal or tiled, a crate is made with a distance between the bars. Additional roof elements are racks, spacers, struts and crossbars. They not only complement the main elements, but also give additional rigidity to the entire roof. The main elements of the roof are made of wood material, so after installing them, it is necessary to immediately cover the roof. This will protect the wooden roof structure from atmospheric precipitation.
