GreenGrid--A Modular Green Roof System

While green roofs can be created using a wide range of components and configurations, nearly all involve an integral relationship between the roof membrane and the growing medium—typically through an intermediate drainage layer. Often, green roof systems are sold as part of a new roofing package. Introduced in August, GreenGrid™ takes a markedly different approach. Roy F. Weston, Inc. has teamed up with ABC Supply to develop a

modular green roof system that simplifies the installation process.
