The roof is the crown of each building, because it affects not only the appearance of the facade, but also gives it a special and completed look. Therefore, by defined with the correct combination of the size of the structure, each person faces the need to calculate the roof skate.

Of course, it is best to entrust the solution to this issue to those skilled in the art, however, if you wish to do it yourself, you should familiarize yourself with several approaches, each of which is based on a certain priority.

Factors that determine the corner of the roof of the roof:

• climatic conditions of this area;
• roofing building materials;
• wind speed;
• roof project;
• facade design.

Types of roofing and calculated angle of inclination:

1. Single car

It is the most common form for the construction of utility structures. Its main advantage is expensive. The recommended angle of the skate of this type of roof varies from 9 ° to 25 °.

2. Two-batch

Such a roof is formed by connecting one line of 2 squares that create skates in different directions. The optimal corner of the two-tie roof rings varies from 5 ° -60 ° and depends on the type of roofing materials and snow load. If a large snow load is planned, then the roofs and its angle of inclination increase from 45 ° -60 °.

3. Walmovaya

Today, this kind of roof is the most popular construction method. The bias in this case varies from a minimum to the maximum - it all depends on your imagination.

4. Mansard

It is one of the options for a holm roof, which is somewhat complicated. It involves an attic space, therefore it implies the creation of vapor and heat insulation. At the same time, there is an increased angle of inclination and a broken system of the skate.

Thus, there is a huge variety of forms and types of roofs, so, starting construction, try to provide all the factors affecting it and justified in this region.

How to calculate the roofs

Most often, the angle of inclination of the roof varies from 11 ° to 45 °.

For example, with an increase in the angle, it is possible to significantly reduce the pressure of the snow cover to the roof, however, with too much angle, the load from the side wind can increase, so they will have to buy expensive durable roofing materials, crates, rafters, etc.

Even the minimum roof skate angle requires a certain amount of materials, and with a large slope, you will have to take care of the expenditure of a huge amount of financial resources.

Calculation of the roof of the roof

In order to determine this indicator, we will need to clarify 2 parameters:

• snow load parameter in this region and terrain;
• total mass design.

Initially, the weight of 1 m.kv should be determined. Roof coatings, then the resulting data to be folded for all layers of roof and continue to multiply this indicator by 1.1.

What is the roof of the roof?

Roof angle depending on climatic conditions

In those regions where there is heavy snowfall in the winter, the roof load increases, so the angle of the skate is selected from 45 ° -60 °. Such angle ensures the gathering of large snow masses, thereby reducing the load on the roofing elements.

In the event that a residential building project is created for a terrain with strong winds, the construction should provide minimal sailboat, that is, a wind load on the design of roofing elements. In these projects, the calculation of the roof slope angle is chosen from 9 ° -20 °.

Unfortunately, in practice, only weather conditions are rarely found, most often specialists have to take into account other factors, so the angle value is selected by the average of 20 ° -45 °. It is for this reason that most roofing buildings are intended for use with this roof angle.

The angle of inclination of the roof depending on the used building materials

For each type of roofing building materials, there is its own minimum roof rope angle:

• for metal tile, the minimum angle of inclination is 14 °;
• for Ondulina - 6 °;
• for professional flooring - 12 °;
• for set elements (tile, slate, etc.) - 20 °;
• for rolled type of coatings, the angle depends on the number of layers - than them more, the less the minimum angle. For example, with a three-layer coating, an angle varies from 2 ° to 4 °, with a two-layer - from 10 ° -15 °.

After how the corner of the roof is calculated, the bearing ability of the frame elements should be calculated. Along with the roof, they must withstand a different type of load formed during operation. As for the shade of the crate, it depends on the type of building materials used and from the inclination of the roof.

The angle of the linker of a single-table type, depending on the roofing materials used:

• slate - 20 ° -35 °;
• folding roof - 18 ° -30 °;
• ruberoid - 5 °;
• professional flooring - 8 °;
• metal tile - 30 °.

If the slope of sufficiently light roofing materials, such as galvanized metal or professional flooring, do less, then under the weight of the snow cover, the roof can progress. Therefore, in that region, where snow is quite a lot and it lies for a long time on the roofs, it is better not to risk.

It is also important not to reduce the angle of the row for the roof of the metal tile and slate, because in this case the water can be leaked to the docking nodes.
