GREEN ROOF
Green Roof Systems Defined
Grass or turf roofs have been around since the Viking times if not far earlier and make for a decorative and durable roof covering. Green roofs have been made by depositing topsoil or other growth media on flat roofs and seeding them (or allowing them to self-seed as nature takes its course).
Maintenance in the form of simple visible inspection and removal of larger rooting plants has allowed these roofs to be successful in that they provide an excellent covering and UV light barrier for the roof waterproofing membrane. With some systems, the manufacturer requires that a root barrier membrane be laid above the waterproofing membrane. If well planned and fitted, the mass of the soil or growth medium can provide a good heat buffer for the building – storing the heat of the sun and releasing it into the building at night and thus keeping inside temperatures more even. Sudden cold spells are also buffered from the building.
​
One predicted problem with large green roofs is that fire may be able to spread rapidly across areas of dry grasses and plants when they are dried, for instance, in summer by hot weather: Various countries are stipulating fire barrier areas made of, for example, wide strips of (partly decorative) gravel.
​
Sedum is emerging as a favourite as it is easily transported and requires little maintenance as it is a succulent plant which remains close to the ground throughout its growth, has mild roots which don't damage the waterproofing membrane and changes colour in the seasons in greens, browns and purples to give a pleasing effect to the eye.
