The provision of a green roof is increasingly becoming part of local government planning requirements, for example in Sheffield, where this programme was filmed, the council requires that new buildings in excess of 10,000m2 or of ten dwellings or more have 80 per cent vegetated cover. This programme looks at the different types of green roof and examines how they are made and maintained.
- The difference between intensive and extensive and common misperceptions
- What are brown roofs?
- What green roofs can and cannot do
- The importance of using the correct substrate at the right depth
- How good design largely negates the need for irrigation systems
- Why fertiliser and extra feed should rarely be required
