The most popular type of green roof is the sedum mat – here matting planted with hundreds of sedum plants is laid over lightweight growing medium and protective barriers preventing the roots of the plants effecting the waterproof roof membranes and roof structure. Sedum roofs look good all year round and carefully chosen plants can provide a succession of colour and interest. One of the biggest benefits of the sedum roof is that it requires very little annual maintenance.
Living roofs can also be planted with turf which would give your garden room a thick and luscious green roof but this type of roof can be heavy so requires a strong garden room construction, you will also need to be able to get up onto the roof to cut the grass!
