Green Roofing

A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane.

The benefits of a green roof include reducing rain water run-off, providing insulation so reducing energy consumption, creating a habitat for wildlife, improving air quality and improving the aesthetics of the roof.

There are many different types and forms of green roof, including extensive, intensive and biodiverse or brown roofs. The terms used refer to the depth of the substrate used and the level of maintenance the roofs require. Intensive green roofs are garden-like in appearance and designed to be used but require a high level of maintenance and built in irrigation. Extensive green roofs are usually planted with sedum and are not intended for public access. Instead they offer a light weight, low maintenance solution.
