Does the Green Roof replace the waterproofing membrane?
A Green Roof system does not replace the waterproofing membrane. The entire system is placed on top of the waterproofing membrane. The choice of the type of waterproofing can be anything from bituminous membranes to PVC and liquid plastics. Additional root barriers are required if the waterproofing is not root protected. An asphalt shingle waterproofing is not an option. Green Roofs cannot be installed directly on shingles.
