Extensive green roof:
Lightweight and drought tolerant, extensive GreenScapes Green Roof designs are low maintenance with no irrigation required in most climates. This shallow growing media option is typically used to mitigate the effects of the urban heat island phenomenon and reduce storm water runoff.
Intensive green roof:
GreenScapes Green Roof designs have increased growing media depths and therefore look more like traditional roof gardens since they can host a wider variety of plants. They are designed to be accessible for recreational use as well as add green space for visual pleasure. Hardscape elements such as pavers, benches and water features can also be integrated.

Backed by the industry-leading quality assurance program.

Nothing threatens the structural integrity and interior environment of a building like water ingress. And the The HydroShield™ Quality Assurance Program is a proven systematic approach resulting in the most comprehensive water protection in the industry. Period. Read more.
