What is a Green Roof?

Green roofs are a roof that allows plants, trees and shrubs to grow in a specially designed light-weight growing medium.

The three main types of green roof systems are:
  • complete systems where all the different components including roof membrane are an integral part of the whole system
  • modular systems that are positioned above the existing roofing system
  • pre-cultivated vegetation blankets that consist of growing medium and plants that are rolled onto the existing roofing system with drainage mats and root barriers as required
Green Roofs Differ from Rooftop Gardens
The rooftop garden is simply a garden, usually in containers, that is located on a rooftop. The rooftop may be a house, an office building, a garage, shed or any other structure that has a suitable surface and is strong enough to take the extra weight. More here.
