Green flat roof system, designed to reduce energy costs by creating natural insulation. They create peaceful retreats and recreational areas, natural habitats for wildlife, and they absorb storm water thereby reducing run-off into overworked sewer systems. On a wider scale, in city environments, green roofs improve air quality by absorbing pollutants and by helping to reduce the urban heat island effect.

City and suburban developments absorb and trap heat, whereas evaporation from a green roof has been shown to cool surrounding air temperatures. A green roof must, like any roof, protect the building from the elements via a high quality, totally dependable waterproof membrane. Polyroof’s cold liquid-applied seamless membranes are suitable waterproofing solutions for use in green roof systems because they are flexible enough to easily accommodate structural movement as well as being lightweight and extremely durable. When used in a green roof system the durability of Polyroof membranes are even further extended since there is no UV penetration.
