We will try to reveal more details about it. "Green roof " hard to call today, as roof of this type were used many hundreds of years ago. They are widely used for housing in countries with extreme temperatures - in the Scandinavian countries, they are rescued from the cold, and in Africa - from the heat. The prototype of the modern "green roofs » were roof , covered with turf - simple cheap and excellent thermal insulation.

Until the mid XX century "green roof » were considered exotic, and distributing them was very limited. However, at this time, urban population of Europe felt the longing for greenery, the area which in expensive urban land decreased dramatically fast, felt the degradation of the environment and the need for more greenery in urban areas has become an urgent task. During this period, conducted a large number of experiments and studies to determine the necessary types of roofing materials , protivokornevyh materials, drainage systems, the compositions of fertile layers, etc. The intensities of the research facilitated by the fact that the use of "green roofs » reduces the volume of stormwater entering the sewerage system, and improve the composition of air in cities. All together, this created a new kind of roofing , now widely distributed in European countries, and now have found the application and on our open spaces.

Caring for their needs during the first years, and after they become sufficiently twice a year weed the lawn and check the status of roof . When the device intensive roofs , thanks to a layer of substrate thickness up to 60 cm, possible planting and trees and shrubs. Roof in this case should be exploited, as caring for plants should be regular. Here it can apply their knowledge landscape architects. Naturally, such an increase in the thickness of the roof pie would entail the use of structures that can absorb a significant burden on the coverage that will result in a substantial increase in the cost of construction.
