Extensive green roofs provide an ecological protective layer for waterproofing membrane and an alternative to ballast layers such as gravel or paving blocks. They feature low height and are lighter than intensive roofs. Vegetation dedicated to this type of roof includes various species of sedums, ornamental grasses and herbs. They can be planted as seeds, rhizomes, or ready-made vegetation mats. These plants are generally undemanding, so care is limited to one or two annual inspections. Additional irrigation is also usually not required on extensive roofs.
Sedum Carpet is a visually attractive roof proposal in extensive cultivation, requiring no special care.
