Biodiversity
The biodiversity benefits of green roofs are manifold. The greening of a roof can support rare and interesting types of plant, which in turn can host or provide suitable habitat for a variety of rare and interesting invertebrates.
New developments lead to a loss of habitats - green roofs can contribute to biodiversity and address local biodiversity action plans. In particular they have been shown to favour many rare invertebrates found on brownfield sites, as well as ground-nesting birds such as skylarks.
Green roofs contribute to a greener urban environment and quality of life for communities in high density developments.
A roof life is at least doubled with the addition of a green roof, thereby reducing resource use in roof replacement and repair.
