Modern flat roofing is a successful combination of advanced technology and materials with improved performance characteristics. The process of waterproofing and warming the roof becomes an affordable exercise that guarantees the result for years to come. What materials should be insulated roof?

Under the roof of your house
The appearance of a flat roof has opened up new horizons for the organization of roofing systems. Houses with a flat roof are attracted not only by their original and characteristic appearance, but also by a number of advantages over traditional pitched roofs.
It is not difficult to guess that the device of this type of roof assumes a slight slope of the flat roof, namely to 3-5 percent. Flat roofs distinguish insignificant material costs for installation and installation. Flat roofs are capable of withstanding significant wind loads. The total area of the roof covering of a flat roof is an order of magnitude smaller than that of a pitched roof.
Naturally the amount of material for the device of waterproofing and heat supply will be less. The obvious fact is that for installation and installation of a flat roof type, less time and costs are required. Agree that spreading the design of houses with flat roofs is not a mass phenomenon.
The standards of classical construction can be called a deterrent in this case. In vain! What does it feel like seeing a country house or a stylish cottage with a flat roof? We will not hide it, this is envy and admiration, and also the desire to arrange this type of roofing on your house. Therefore, take into account all the advantages of a flat roof and carry out the installation yourself.
Flat roofing device
Traditionally, the roof has been and remains the main protective part of the building from adverse temperature and humidity effects. The device of flat roofing is carried out in cases when the construction of other types of roofing is inexpedient for technical reasons.
Flat roofs are designed for buildings, based on the definition of which, are divided into types:
• Operated
• Unexploited.
Roof operated is used for buildings that are supposed to have a systematic access to the roof or where the location of massive equipment is expected.
The roof is not operated, on the contrary, it does not require access to the roof on a daily basis, but only in emergency situations.
Thus, the validity of the operation of a flat roof will be marked by a specific technology of arrangement and a list of necessary materials for this process.
The plan of the device of a flat roof consists of the following components:
• Concrete base with an inclined layer
• vapor barrier and thermal insulation
• waterproofing and geotextile
• decorative layer.
The basis for a flat roof in most cases is reinforced concrete, which can be a monolithic structure or a hollow slab. On top of the concrete foundation, the roofing elements are laid, these are the layers of steam, the body insulation and the waterproofing layer.
The layer of waterproofing and the insulation of the flat roof are made with the help of an additional layer. According to the normative documents and rules for the erection of the roof, the roof must withstand:
• total weight of the structure, including communication elements
• the normative weight of the person who serves the roofing
• The mass of snow falling in the winter.
A flat roof, the technology of which depends on the purpose of the room, can be successfully mastered and made the device of the roof with their own hands.
The main thing is to make the right choice of insulation and waterproofing so that it does not suffer in the winter in search of a compromise "How and what to insulate a flat roof."
Materials for flat roofing
Modern building materials designed for the construction of flat roofs simplify maintenance and exclude a number of actions. So, for example, the membrane roof completely deprives of the problems of cleaning snow and ice from the roof in winter after heavy snowfalls. By the way, the polymeric membrane has zero water absorption coefficient. And this means that a quality membrane can withstand a million (!) Thawing / freezing cycle, allowing the accumulation of moisture on the roof.
The only occupation of the owners of flat roofs, equipped with a membrane, will be the collection of garbage near the drainpans several times a year.
The main materials used for waterproofing and warming flat roofs are:
• membranes
• Welded waterproofing
• Soft roofing materials.
membranes
It is known that the construction of a membrane roof can be compared with the construction of a rigid roof. However, with the advent of PVC membranes and TPO membranes, the roofing fabric acquires stunning characteristics, creating an elastic and reliable coating. It is possible to perform the device of a flat roof using membranes independently at any time of the year, because the membrane is not afraid of temperature changes.
Certainly, polymer membranes of PVC represent a special class of materials, which presents a fundamentally different approach to the installation of flat roofing systems. First of all:
• high strength, resistance to UV rays and frost resistance
• Significant service life.
For reference, the manufacturers of roofing membranes provide a quality guarantee for up to 20 years, and the predicted service life is 50 years. Agree that such indicators of longevity are credible. In addition, a significant width of the membrane field allows you to select the optimal working width for any flat roof.
surfaced waterproofing
The welded waterproofing of the roof is a heavy-duty layer with a non-rotting cloth. The base of the deposited materials is impregnated with modified bitumen. Recall that modified bitumen has excellent resistance to any mechanical deformation and undesirable temperature changes.
100% tightness and a long service life of up to 30 years make it possible to produce a waterproofing of a flat roof quickly and with guaranteed quality. Laying of the deposited materials is done on the prepared roof using a propane torch.
soft roofing materials
Roofing materials are soft for insulation and waterproofing of flat roofs came up as it is impossible by the way. Probably, for a reason in Germany about 70 percent of flat roofs are constructed using such materials. The material is practically not subject to cracking due to the use of fiberglass and fiberglass as a basis.
Convenience of the roofing is achieved due to the plasticity of the material. Therefore, soft roofing materials are successfully used for waterproofing pools and foundations.
