[[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. Growing medium depth determines which plants can be planted, and the components of green roofs can either be loose-laid or fused together. The proper installation of green roofs can help to achieve water balance targets, promote biodiversity and provide green space.
