"This standard, along with the recently approved fire standard, will provide the US market with the guidance that it needs to safely install vegetative or green roofing systems, which are an expanding segment of the roofing industry in the US. It is the result of an industry wide effort involving manufacturers, contractors, designers, green roofing professionals, and testing agencies." said Mike Ennis, Technical Director for SPRI.

“This new standard has been under development since 2007 and is the result of close collaboration between experts at Green Roofs for Healthy Cities and the Single Ply Roofing Industry and it should help to open the doors to better design practices in the industry and allay concerns about wind uplift,” said Steven Peck, President of Green Roofs for Healthy Cities.

“The RP-14 Wind Design Guideline combines established design principles of conventional roofing systems with the wind tunnel testing conducted at Southern Illinois University Edwardsville to set minimum requirements aimed toward reducing the risk of wind damage to vegetative green roof systems. The standard provides clear design criteria that will help pave the way for growth of the green roof industry in even the most challenging wind zones of North America. “said Kelly Luckett, Chair of GRHC’s Technical Committee and President, Green Roof Blocks.
