What is a roofing pie?

On how high the roof will be made, the life of the entire house depends, and the comfortable atmosphere in it. The loss of heat through the roof can make the room too cold, and insufficient waterproofing will inevitably lead to Leaks. So each layer of coating in the so-called roofing pie has its own meaning.

What are the roofs?

Depending on the design of the roof, the materials necessary for its finishing are also determined. There are two main types of roofs: flat and pitched. Pitched roofs are more suitable for structures in temperate climates, since it is easier to carry a large amount of precipitation. Flat roofs are more suitable for office or technical premises, sometimes they are made as an exploited area, placing a terrace or a winter garden. Accordingly, the roofing cake also changes. Not all materials are suitable for finishing a pitched roof, not everyone is suitable for creating a roof-terrace. In addition, the role of the premises under the roof plays a role. If this is a technical room or a cold attic, the work on insulation and insulation will not proceed as in The case with an ordinary residential building.

What does a roofing pie include?

So what is a "recipe" for a roofing pie? Its components include interior decoration of the space under the roof, a couple of centimeters of the air gap for ventilation, a layer of special vapor barrier film, a layer of thermal insulation between the rafters, waterproofing, crate and roofing material, and gutters and railings or bridges for safe movement on the roof, snow holders For safety in the cold season and decorative elements, like weathercocks. Roof pie for flat roofing does not involve snow-holders and decorative elements. In addition, in some cases, the roof is located on the ceiling, and not on rafters. If the premise under the roof is reserved for technical purposes, it is not required to insulate and vaporize the roof - the insulation layers will be located on the floor, protecting from Heat losses of the premises located below.

Roof pie for soft tiles, bitumen and other materials

In the case of a roof covered with bituminous shingles, a layer of waterproofing material can be excluded from the pie. Bitumen creates a waterproof coating without additional films, waterproofing is only required at joints, corners and cornices. And lay this film is needed right before the installation of the roofing material, and not under the crate. If a roofing cake is made for a roof made of soft roll coatings, an additional lining element will be required. This is a polypropylene film that guarantees waterproofing when coated with a layer of absorbent woven viscose and polypropylene. For a roof made of metal tiles or rolling sheets, an additional layer of soundproofing is required, otherwise it will be too noisy during the rain. Thus, it is obvious that some layers of roofing pie are always present in it, and some are determined by the type of concrete structure.
