Green Roofs

Green roofs have been used in some parts of the world for a long time. Today, systems are being developed that will allow us to retrofit almost any existing roof to bee a green roof. Why is this important? Habitat and green space that is being lost to building can be replaced to a dgree by green roofs. Many species of insects and birds who are being pushed out of their native habitat can remain there if there are green roofs.
Research shows that green roofs can also help lower the temperature of urban heat islands.
Plants will assist in controlling rainwater as well. Because they will retain water it eases the stress on drainage systems. Lightweight growing mediums and lightweight planting and waterproofing mediums make it possible to have a green roof without any chaqnges to existing roof structurs in most cases. Some installations will require more structural reinforcement to grow trees or have a rooftop plaza.
According to some studies, the existence of a green roof also extends the life of the roof by as much as 200%. And you never have to mow it.
