Description[edit]
Green roofs are composed of several layers (waterproof membrane or existing membrane, root barrier, drainage layer, filter fabric, growing medium) that support the growth of plants and other vegetation on top of a roof.
Types[edit]
There are two main types of green roof systems: extensive and intensive.
- Extensive green roofs have growing medium depths of 10 cm to 15 cm (0.1 m to 0.15 m), maximum structural weight loads of 250 kg/m2, and vegetation is primarily limited to sedum spp or commonly known as stone crop.
- Intensive green roofs have growing medium depths greater than 15 cm (0.15 m), no maximum structural weight load and various plant types can be incorporated including native flowers, trees and shrubs. See green roof plant types
