Roof pie

26.05.2020

The basis of any design of this type is rafters that carry out supporting functions. All other layers are already attached to them.

Roofing pie for metal tiles: cold roof

The device of the roofing pie for the metal tile is simplicity. In this case, the insulation itself is not used. After all, a cold roof is made only when it is above the unheated room. Therefore, the roofing pie for the metal tile will include only the controlleep, the hydraulic tank (most often film) and directly the tile itself. The film is attached to the crate with small cloves or with the help of a construction stapler. In this case, she needs to set a certain sag in advance, within 15-25 mm., In order to ensure sufficient ventilation of the sheet. Otherwise, excess moisture will accumulate here, and then even the highest quality metal tile will be subject to corrosion.

The device of a roof pie for a metal roof for a warm roof

In modern suburban construction, however, they rarely make a cold roof if a metal tile is used. The fact is that this material is quite booming, and if the thermal insulation of the ceilings is insufficient, in the rain and wind the sensations of those who are in the house will not be the most pleasant. Therefore, the roofing pie for metal tiles is more often mounted as for a warm roof. This allows not only to reduce the noise level, but also to more efficiently use a subcutaneous space. Of course, the device of a roofing pie for a metal tile in this case is more expensive, however, its operational characteristics compensate for additional costs.

If you move in the direction from the inside out, the roofing pie for the metal tile will include the following layers:

a vapor barrier barrier that passes excessive moisture outside, but does not let it inside;

rafter design;

insulation, which is located between the rafters;

ventilation gap;

waterproofing barrier (can be used both a film and a membrane);

a counter -rod that presses the waterproofing;

crate mounted from a beam;

metal tile.

Such a device of a roofing pie for a metal tile allows you to maintain the heat of the room. However, the whole system will be quite effective only if the insulation is correct to choose the right. From this point of view, one of the best materials is considered to be a foam that does not absorb moisture. However, it is quite expensive, so more hygroscopic, albeit relatively cheap mineral wools are often used.

The roofing pie for the metal tile is mounted quite easily. The main thing is not to forget about the ventilation gap. It is usually left between the metal tile and a hydraulic bank (enough at 10-15 mm), but it is better that there is another channel-between the overhang of the coating and the skate of the roof.

Roofing Pie for Ondulin: Features of installation

Ondulin is a roofing material consisting mainly of bitumen and polymer components. Its main advantages are a high degree of protection against adverse environmental effects, as well as ease of installation and operation. The roofing pie for Ondulin has its own characteristics. When installing it, you need to follow the manufacturer’s instructions. Theoretically, it consists of the same layers as the roofing pie for any other materials. However, the manufacturer of Ondulin produces special materials for ventilation, steam and waterproofing. So special ventilation pipes Ondulin make out ventilation ducts laid in the roof. The junction of the roof and the chimney is glued with special tapes of Ondufles, serving for waterproofing. They are also used for waterproofing the cornice of the roof and any superstructure on the roof.

In addition, the roofing cake for Ondulin involves the use of special lining material as a vapor barrier, which is called onidutis.

Roofing pie for soft tiles: nuances of the scheme

Soft tiles are another name bitumen tile. This is inexpensive, but durable and reliable material. The roofing pie for soft tiles is of two main types: for insulated and for a cold roof. In both cases, the heater, hydraulic – and a steam tank are used, and the ventilation duct is also made. The roofing pie for a warm roof consists of the following components laid in the indicated sequence:

rafter design;

vapor barrier;

black crate;

thermal insulation;

a hydraulic tank (film or membrane);

counterbrus;

crate;

plywood;

lining carpet;

directly bitumen tiles.

The sequence of work in this case is indicated from above. Although you can insulate the roof and below, it depends on the specific situation. For a cold roof, the roofing cake looks somewhat different and consists of a rafter structure, a walking crate, plywood, lining carpet and bitumen tiles.
