Green Roof

A flat or shallow-pitched roof partially or fully covered with vegetation planted in a growing medium over a waterproof membrane and drainage layer. Green roofs provide biodiversity benefits, reduce surface water runoff, improve urban air quality, and provide additional insulation. Sedum (extensive) green roofs are low maintenance and lightweight; intensive green roofs can support deeper planting but require a structurally stronger roof deck.
