There are two categories of green roofing:
1 Extensive green roofs, which use lighter-weight soils and thinner soil depths and can feature sedums, grasses, herbs, and other smaller plants. Once designed and installed, such roofs can typically be maintained by existing building maintenance staff.
2 Intensive green roofs, which use heavier-weight soils and thicker soil depths to accommodate the planting requirements of woody vegetation, shrubs, and even small trees. These roofs may require the ongoing attention of landscape professionals, in addition to existing building maintenance.
