GAF’s GardenScapes feature simple, effective designs that start with a choice of GAF’s single-ply TPO or multiple-ply TriPosite™ XL roofing systems as the waterproofing layer. On top of the membrane is GAF’s exclusive DuraGro™ 4-in-1 drainage foundation system, which protects the roofing membrane from direct contact with the growing medium, retains just enough water to help keep the plants from drying, slows the drainage of excess water into storm sewers, and helps screen the drain water to keep from clogging. Next is GAF’s custom-formulated StartRite™ growing medium, designed for specific geographic locations, with a special organic superfood. GardenScapes systems offer a choice of plant varieties suited to specific climates. For more information, visit www.gaf.com.

It is based on advanced German technology — engineered and refined over more than four decades of ongoing R&D. In Europe, where the green roof industry is long-established, Xero Flor is the technology of choice, according to the company. It has been proven successful and sustainable in tens of thousands of flourishing installations worldwide, including projects in more than 30 states in the United States.
