A green roof or living roof is a roof that is installed to a building and partially or completely covered with vegetation and a growing medium which is planted over a waterproofing membrane. For further roof membrane protection the installation should include additional layers such as a root barrier along with integrated well designs drainage and irrigation systems.
The two main types of green roofing systems are referred to as Extensive, Intensive and Bio-diverse
Extensive Green Roofing Schemes
Extensive green roofing scheme provide a light-weight, low maintenance, green roofing scheme that are the most popular choice for our clients. Extensive green roofs are not usually designed for general public access, and procured in the main for their ecological benefits.
Extensive green roofs use a Sedum vegetation that has the properties to flourish even in the harshest of environments. Extensive green roofing systems are cost effective and are lightweight to suit most roof weight loading restrictions. Extensive green roofs can be designed for new buildings and can be retro-fitted on building refurbishments.
Intensive Green Roofing Schemes
Our intensive green roofing schemes provide a much deeper substrate and drainage design to allow for the planting of more complex rooted plants. Intensive roofing schemes are installed within roofing areas that are accessed more regularly. These roofing systems are often more visible as they are much more aesthetically pleasing on the eye with a variety of shrubs, flowering plants and grasses used. Intensive green roofs require more regular maintenance and safe roof access systems need to be installed.
Bio-Diverse Green Roofs
A Bio-Diverse roof is designed and installed with a range of materials to encourage natural habitat and wildlife to utilise the area. The roofing schemes are finished in a range of materials that provide ecological benefits to the area. These materials include rubble, gravel, rubber and logs and aim to attract bees, birds and small insects. Bio-Diverse roofing systems help to support the local environment and can help with the building planning processes and sustainability targets.
