Selection of flat waterproofing roofing materials
From the very moment of the emergence of architectural and building arts, two types of roof construction have been established: sloped, at some angle to the horizon, and flat, located strictly horizontally. Each of these two species is in demand, but in countries with a temperate climate and large precipitation, it is the pitched roofs that prevail. Buildings with a flat roof are located mainly in warm countries, where natural rainfall is rare. But recently, in the northern regions, a second type of roof is often encountered, the materials for which must be chosen wisely.
Basic materials So far, in order to protect the roof from moisture and cold, two types of coatings are used: overlayed and self-leveling. The first are thin ribbons, twisted into rolls, like wallpaper. They are glued to the surface of the roof with molten bitumen resin, hence the name of the material. The second type - mastic bulk materials.The method of their use is interesting and original. Such coatings are applied using a standard paint brush or roller, after which the material will polymerize, creating reliable protection against precipitation. What material to choose? properties such as waterproofing, durability, resistance to sunlight, durability, low weight, as well as the level of complexity during operation. In addition, there are many other conditions that are recommended to be observed. However, you can stay on the above properties. Welded roll-bituminous materials well protect the roof from various kinds of natural precipitation and sunlight. Initially, this coating has a size of 1 * 10 meters, after which it is rolled up and sent for sale. Polymer-membrane materials will ensure the durability of the roof. Their service life sometimes reaches 50 years. By their qualities, these coatings surpass roll-bituminous materials. First, the width of the roll of polymer-membrane roofing can reach up to nine meters, which allows you to get rid of excess joining seams.Secondly, during the roofing works, it is not necessary to use a burner to melt adhesive resin, as is the case with roll-bituminous coatings. To do this, you can use a special glue. New word in the construction are self-leveling mastic roofing materials. Their advantages are the absence of seams, ease of use and efficiency. Due to its property of freezing in air, mastic coatings fill all small gaps and, while freezing, reliably protect a building from destructive factors. To ensure the best effect, several materials can be combined at once. Also, in order to make the roof aesthetic, it is often covered with decorative ceramic tiles or artificial turf.
