Intensive green roofs are traditional-style roof gardens, with large trees and shrubs. They often are accessible to the public and can include garden paths, seating, and other features that make the roof an outdoor room. (8” - 4’-0”)

Extensive roofs are not designed for public use but are more for environmental benefits. They help to mitigate the effects of urbanization on water quality, often dramatically, by filtering, absorbing or detaining rainfall. (1” – 7”)
