Today, among the variety of existing roof structures, a leader confidently takes ventilated roof. Reviews of it can be heard from professional builders, as well as from people who live in houses with such roofs. Of the total weight of it stands reliable protection against swelling sheathing falling under it of moisture, the formation of mold fungi. This type of roof is the best, it allows you to save money thanks to the possibility of its arrangement on an old design. Well ventilated roof allows to dry wet insulation and rafters.

Ventilated roof - construction

ventilated roofing is no different high complexity. It consists of three elements, which serve to ensure the free circulation of air:

• ventilation gap between the waterproofing and insulated layer,
• ventilation gap between the waterproofing layer and the roof decking. The air can circulate in all planes, regardless of the complexity of the structure,
• venting a roof, which component obschedomovoy ventilation system.

This species differs from other roof location of the ventilation system. Due to the continuous air circulation, the moisture evaporates quickly and the temperature is kept at approximately the same level.

Effective functioning of the ventilation system depends on the proper installation under the roof battens.

Property ventilated roof - a process that has some differences from other methods of arrangement of its species. . For residential structures such as garages, sheds, etc., can be built not insulated coating includes such components as:

• rafter system,
• obreshetochnaya design,
• waterproofing layer,
• roof decking.

film is used for waterproofing. It is attached to the rafters. It prevents the ingress of water, increasing the operating life of the roof. Such a construction is suitable only for buildings, intended for household needs, as due to lack of insulation, it is cold. If the structure is mounted to the structure, where people will live, it is necessary in addition to the above layers and add another plate heat insulation, as well as film, prevents the condensate liquid.

The components of this material:

• two-layer laminated film,
• material that absorbs water,
• polypropylene fabric.

In addition, during the construction of ventilated soft roof should be equipped with air vents under the eaves.

Advantages of a ventilated roof

This type of design is so popular and in demand due to their numerous advantages, such as:

• to continue to work at temperatures up to -20 degrees (but during heavy rain and heavy snow is better to suspend the installation)
• during the reconstruction of the roof of the old flooring can not be dismantled, and to lay the roof straight at him. This achieves maximum efficiency ventilated roof. Price of the roof is reduced significantly, as well as significantly save time,

• in use, completely dry out all parts of the roof: flooring, insulation material overlap. Through this minimizes the risk of rotting green boards, mold or fungus that can cause considerable harm to the overall design,
• old flooring, which is ventilated roof, after thorough drying starts to operate fully, i.e. the house a two-layer roof,
• due to drying and constant air circulation, swelling sheathing roof easily eliminated,
• this design is not afraid of cold weather and sunlight, does not rot, does not suffer from thermal shocks, adverse weather conditions and mechanical damage.

Varieties ventilated roof

To date, there are many varieties of ventilated roofs. Leaders among them are scanty and flat. They can serve for different types of buildings, materials for their installation are required the same, the difference is only in the design itself.

Flat ventilated roof began to apply several decades ago when thermal insulators with ventkanals appeared on sale, with extra liquid. It was more expedient to use such a kind of roof for apartment buildings.

Roofing design was made of such components as:

• concrete plate at the base of the roof
• vapor insulation material
• thermal insulation material
• screed
• waterproofing,
• polyurethane material
• polyurethane mastic,
• roof decking.

A fence from concrete was built around the perimeter. Using bulk material of the shield from the roof structure. To date, this role is taken by polyurethane foam, which is also a good sealant. All ventilation pipes are isolated by this material.

Flat roofs are pretty cool, but their popularity does not fall due to the fact that while they are convenient and economical.

Scope roofs, in contrast to flat, admiss the air flow through the bottom skes, and remove through the horse. Together with the air, an excessive liquid accumulated under the roof is displayed and the heaters dry out. For forced ventilation, special fans are attached on the roof.

For non-residential buildings, the roof can not be inspired, but for residential - you need insulation from mineral wool.

Stages of mounting

Installation occurs in this sequence:

• it is necessary to eliminate the irregularities and cracks cementing or by asphalting them. We must not forget about the bias of the roof, which should be at least 2-3 degrees,
• after that, vaporizolation and insulation material is mounted,
• next should be waterproofing and screed,
• the final stage is the laying of roof flooring.

In the process of work, you can not forget about the isolation of the ends of the ventilation pipes. Only under all the details will perform their functions for many years a soft ventilated roof. Photo and video illustrating the above-described installation process can be viewed on this page.
