The life of the whole house depends on how well the roof is made, and the comfortable atmosphere in it. Loss of heat through the roof can make the room too cold, and insufficient waterproofing will inevitably lead to
leaks. So each coating layer in the so-called roofing cake has its own meaning.
What are the roofs?
Depending on what the roof structure is, the materials necessary for its decoration are determined. There are two main types of roofs: flat and pitched. Pitched roofs are more suitable for buildings in temperate climates, as they can easily tolerate large amounts of rainfall. Flat roofs are more suitable for office or technical premises, sometimes they are made as an exploited area, placing terraces or a winter garden there. 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 purpose of the premises under the roof also plays a role. If this is a technical room or a cold attic, the work on insulation and insulation will not be carried out as in
case with an ordinary residential building.
What does a roofing pie include?
So what is a “recipe” for a roofing cake? Its components include interior decoration of the space under the roof, a couple of centimeters of an air gap for ventilation, a layer of a special vapor barrier film, a heat insulation layer located between the rafters, waterproofing, lathing and roofing material, as well as gutters and railings or bridges for safe movement on the roof, snow retainers for safety in the cold season and decorative elements, like weathercocks. Roofing pie for a flat roof does not imply snow retention and decorative elements. In addition, in some cases, the roof is located on the ceiling, and not on the rafters. If the room under the roof is reserved for technical purposes, he does not need insulation and vapor barrier of the roof - the insulation layers will be located on the floor, protecting from
heat loss rooms located below.
Roofing cake for soft tiles, bitumen and other materials
In the case of a roof covered with bituminous tiles, a layer of waterproofing material can be excluded from the pie. Bitumen creates a waterproof coating without additional films, waterproofing is required only at joints, corners and cornices. Moreover, such a film must be laid right before the installation of the roofing material, and not under the crate. If you create a roofing cake for the roof from soft roll coatings, you will need an additional element - a lining. This is a polypropylene film that guarantees waterproofing when coated with a layer of absorbent woven fabric made from viscose and polypropylene. For a roof made of metal tiles or rolled sheets, an additional layer of sound insulation is required, otherwise it will be too noisy during rain. Thus, it is obvious that some layers of the roofing cake are always present in it, and some are determined by the type of concrete structure.
