Flat roofs are the roofs with the slope of 0,7o-7o. This type of roofs is traditionally used in industrial or dormitory buildings. Besides waterproofing and heat insulating, modern flat roofs serve as an additional effective space. In urban areas flat roofs are turned into patios, gardens, recreational zones or children playgrounds.
