Thanks to constant improvement of the industry of production of construction materials, the mankind receives set of courageous design decisions, to the providing buildings magnificent exterior and excellent utilization properties. One of the most advanced materials for covering of roofs is the soft roof having operation term about 15 years which can be prolonged by the simplest repair.
What is represented by soft roof
The bituminous pitches capable to keep plasticity at differences of atmospheric temperatures are always the cornerstone of soft roof. The simplest and known example of soft roofing covering is the roofing material applied to construction of water-repellent layer on flat roofs of multi-storey buildings. More modern materials are multilayered. Are part of covering:
- the substrate having good ability to adhesion and covered with fusible structure;
- the main layer providing mechanical strength; - the reinforcing layer preventing longitudinal expansion and shrinkage;
- The protecting cover having resistance to abrasion and ultra-violet radiation. Soft roofing coverings can be rolled or segmented. Rolled coverings have smaller life cycle, but also the quantity of joints at them are less that simplifies repair. The bituminous tile which at the expense of bigger thickness has the increased operation term is example of segmented coverings, however needs more careful and specific repair.
Features of rolled coverings
Rolled coverings are applied, as a rule, on flat and unexploited roofs. Such materials very quickly become useless from mechanical influence and collapse because of temperature drops year after year. Their main advantage - the low cost and fast laying, however for carrying out roofing works in this case is required team of the trained staff with professional equipment. Stack rolled roofing materials by overlaying of the melted substrate on the cleaned basis.
Bituminous tile
Anyone can roof bituminous tile: for this purpose will be rather normal construction hair dryer. Laying is made many times more slowly than if it has been decided to roof rolled material, but the term of operation of segmented covering exceeds other soft roofing coverings. Mounting of bituminous tile is begun from below, gradually progressing to the fad of multipitched roof and imposing each subsequent element on previous. Thanks to roofing tile has become possible accurately to finish the relief surfaces of roofs having hillocks and roughnesses. The main minus of segmented coverings is their high cost and the requirement to thorough training of the basis.
