Green Roof Systems

An intensive green roof, also known as a “rooftop garden” refers to planting areas that have a depth of 6 inches and up. Deeper soil supports a greater variety of plants such as vegetables, shrubs and even small trees.

Extensive roofs are designed primarily for high performance water management and thermal advantages, while keeping the overall weight of the roof to a minimum. Soil depth ranges from 1.5 to 6 inches deep.
