Building the roof of the house

The roofing of the house is the upper enclosing structure . Although construction is not so easy, but if you know the structure of the roof, understand its basic principles, it is quite possible to implement it on their own.

The roof in the section is something similar to a multilayer pie (by the way, it's called the roofing pie) with the following layers:

• Crate;
• Roofing;
• Heater;
• Roofing membranes (films).

Consider the construction of the roof in more detail.

Rims

When the installation of the rafter system ends, the installation of the crate begins. It can be exposed with a certain step or solid depending on the material. For example, a continuous crate of plywood is installed in the case of a guided soft roof, and the use of corrugated board, metal or ondulin requires a crate with a step of 40-50 cm from a 20-25 mm board.

The curb should have a small overhang along the perimeter of the house, forming the eaves, which provide the building with additional protection from oblique rain.

Roof insulation

Mansard roofs are vapor-insulated with an additional waterproofing layer such as isospan, yutafol and the like. Mandatory vapor barrier for "cold" roofs is not required, but it is desirable to do it.

Roof insulation

Roofs are insulated with thermal insulation materials of both plate and roll type, say, urso, isover, rockwool. Used heaters should be frost-resistant (at least 20-25 cycles), biodegradable, waterproof, environmentally friendly - do not emit unpleasant smells and toxic substances.

Between the heater and the crate, an air layer with a thickness of the order of 5 cm should be provided, which is necessary to preserve all properties. It is the device of the control device that does not allow moisture to saturate the heater.

Roof installation

The structure of the roof of the house determines the order of its laying: towards the rain flows, that is, from the bottom up.

Roofing materials are collected on the roof. This process is somewhat like working with a children's designer. Roofing materials, on which there are no fixing holes (corrugated cement-fibrous sheets, metal roofing, corrugated board), are completed with roofing nails under the color of the coating.

They are slaughtered in the comb of the piece element. In this case, rainwater can not get on the nail on the boards of the crate. The effectiveness of protection against moisture increases the rubber gasket, which is placed under the head of the nail.

The construction of the roof is carried out according to the following list of works:

• Measure the area of the coating;
• Lay the roof covering;
• Install shaped elements;
• Trim the cornice overhangs;
• Mount snow-retaining elements;
• Install skylights.

Materials

Today the widest choice of roofing materials is offered: slate, tile, isoplastic, metal, ondulin, corrugated board and others.

Recently, a special popularity has acquired a roof structure made of metal, a variety of galvanized steel sheet with a polymer coating. As a result of its profiling, imitation of natural tiles is obtained.

Metal tile has a comparatively low weight, is characterized by simplicity of installation, ecological safety and long enough operation. This material is protected by a multilayer coating and from moisture, and from oxidation during drilling, cutting or any mechanical damage.

True, the metal tile is quite "noisy" - it resonates during the rain.

The roof should be installed in accordance with the safety requirements: do not work in heavy rain or wind, tie yourself to the ridge, use mounting equipment if possible, insure, etc.
