Construction of the roof of a house

The construction of the roof of the house is a very important stage of its construction. It should retain heat, as well as be waterproof, strong and frost-resistant. This is a whole complex of structures with a roofing pie, having many layers, into which windows for the attic andwith an attached drainage system.

How to organize the construction of the roof of the house with your own hands?

First of all, it is necessary to understand all the components of this design.

The roof consists of the following elements:

  • – roofs (various tiles, metal sheets, etc.);
  • – rafter system (mainly this structure is made of wooden, less often of metal parts);
  • – other parts of the roofing pie (various materials for insulation, water and sound insulation, etc.).

Types of roofing.

The roof is a very important protective element of every roof. It should fully protect the house from any external natural influence: rain, snowfall, wind, etc. In order to choose the optimal type of roof for your own home, you need to understand these materials and make your choice based on the advantages you need, its properties and your own financial capabilities. It is also necessary to take into account what load will be applied to the supporting structure. For example, if it is not designed for significant weight, and it is impossible to strengthen its elements, then it is better to use lighter materials, for example, imitating natural tiles.

Today, the roof is divided into two types: soft and hard. Both options include many different materials, but the most suitable one should be selected depending on the type of roof. For example, on sloping types of roofs, experts recommend using a rigid type of roof – natural and metal tiles, slate.

The main advantage of a hard roof is durability. In addition, it is quite strong and beautiful. But creating a roof from such a roof will, in most cases, be significantly more expensive than a “soft” option. In addition, sometimes its device requires the involvement of professional roofers.

Today, metal roofing is the most widely used, as it is a relatively inexpensive and easy-to-install material. For flat roofs, soft roofing is widely used – mastics, polymer-bituminous materials, roofing material. It is made of non-rotting and durable fiberglass or fiberglass. The listed materials are quite convenient when carrying out repair work , since it is not necessary to remove the old carpet (roofing).

The device of such a roof does not require a “strong” supporting structure, as it has a small weight.

Rafter system.

The supporting part of every roof is the rafter system. It takes on not only the weight of the roof, but also gusts of wind and the weight of snow. Therefore, the rafter system must be calculated based on the type (as well as their weight) of the roofing material, the possible weather conditions for the given area, taking into account the thickness of the possible snow cover and the strength of wind gusts. When creating it, force majeure circumstances must be taken into account, creating a significant safety margin in this design.

Wooden rafters are most widely used in country construction, which is due to the excellent properties of wood. They are convenient because they are ideal for covering the roof, and they also fit perfectly under uneven walls.

Roofing cake.

The construction of the roof of the house is simply unthinkable without the creation of a roofing pie. What it is? This is a multi-layered construction consisting of vapor, hydro, thermal insulation and other materials. Its main parts are a gap for ventilation, a moisture-proofing layer, a vapor barrier, thermal insulation, roofing and finishing materials. The roofing cake insulates the attic and completely excludes the formation of condensate.

If you want to build the roof of the house with your own hands, then you need to approach the creation of a roofing cake especially carefully. After installing the roofing material, the installation of the insulation begins, so that there is a certain gap between these elements for ventilation. At the same time, be sure to leave holes for air: outlet (area of ​​the ridge) and for its inflow (place of the eaves overhang).

The insulation is protected from moisture by two special films. One is applied in strips (horizontal) to the crate to prevent it from condensation that forms inside the roof covering. The second film (vapor barrier) protects this material from moisture coming from the room, and is stretched over the insulation from below, without any gap.

Self-construction of the roof requires careful study of all these materials and videobooks as well as the technology of their laying and installation.
