Materials commonly used in the build of a extensive Green Roof
When we refer to "Materials" there are a number of different types of Green Roof materials, such as the plant material, roof filter material, drain material and root barrier. Each of these corresponds to a functional layer within a Green Roof build up.

This list reflects a basic extensive green roof build. Depending on the project and supplier, materials such as irrigation lines and water retention materials could also be incorporated.
