You’ve likely seen plants growing on top of a commercial building or as an alternative to conventional roofing somewhere in your own community. A green roof — or vegetated roof, garden roof, living roof, or eco-roof — is a multi-layered system of plants, lightweight growing media, and other geotechnical components that are installed over a man-made, waterproof membrane.
Green roofs not only transform rooftops into beautiful green spaces, but they’re also the most popular form of Green Stormwater Infrastructure (GSI). Dollar for dollar, there’s no other form of GSI that provides the same triple bottom line — environmental, social, and economic — benefits in both the public and private sectors.
