Roof of the house - functions and types

The roof of the house is the top enclosing structure of the entire building. According to its technological characteristics, a number of functions are assigned to it:

- waterproofing;

- carrier;

- heat insulating.

The top element of the roof is the roof. It protects the building from atmospheric influence.

The structural features of the roof of the house are determined at the design development stage. At the same time, the necessary roofing material is selected. The design of the roof and its slope depend on climatic and operating conditions. Also, the architectural requirements and the degree of capital requirements for the building play a role.

The roof of the house consists of a number of elements. The main ones are:

- inclined planes (slopes);

- rafters;

- crate.

The roof of the house can be designed with a slope angle of planes, large ten degrees. In this case, it is classified as pitched. The project provides options with a slight slope of the planes. This angle can be up to two and a half degrees. In this case, the roof is classified as flat. In individual residential buildings, as a rule, pitched roofs are planned .

Projects of houses with a flat roof provide for its use for various purposes. However, it should be borne in mind that this species contributes to the stagnation of water on the roof. This increases the risk of moisture entering the rooms.

According to the design characteristics of the roof of the house can be attic and combined (bescherdachnoy), and in terms of operation - exploited and unexploited. The design type of the upper building envelope is determined depending on its geometric shape and the roofing materials used. Preliminary calculations take into account wind loads and the estimated weight of the snow floor, as well as the weight of the roofing material used. All these moments can affect the stability of the building. It should be remembered that the selection of the material from which the roof will be erected is directly dependent on the reliability of the foundation and walls of the structure.

When designing the roof, the dimensions of the house and its planning solution are taken into account. If the size of the building is within six meters in width and length, then there will be no problems with the roof. The task is complicated with a total building area of two hundred square meters. In this case, an exact calculation of the number of inter-floor and ceiling beams, the thickness of the rafters and the angle of the ramp is needed.

When you make a roof, you can use different materials. They can serve as slate and metal profiles, roof tiles and roofing.

Which type of roof to choose, the designer decides, taking into account the layout of the building. The view of the upper supporting structure should be combined with the appearance and design features of the entire structure. Particular attention should be given to the reliability of the rafter system. This moment is important for giving strength to the whole structure.

Repair of the roof of the house must be carried out both for the purpose of carrying out preventive work, and if there are any problems in its operation. The technology of the activities will depend on the type of roof material, as well as on the type of the top enclosing structure of the building.
