SPRI to Revise Wind Design Standard for Vegetative Roofing Systems
The update is intended to provide a minimum design and installation reference for those specifying vegetative roofs.
SPRI, the association representing sheet membrane and component suppliers to the commercial roofing industry, announced that SPRI RP-14 2022 “Wind Design Standard for Vegetative Roofing Systems” is being revised and will be re-canvassed for approval as an American National Standard.
This standard provides a method of designing wind uplift resistance of vegetative roofing systems utilizing adhered roofing membranes. It is intended to provide a minimum design and installation reference for those individuals who design, specify, and install vegetative roofing systems. It shall be used in conjunction with, or enhanced by, the installation specifications and requirements of the manufacturer of the specific products used in the vegetative roofing system.
The RP-14 Standard was first approved as an ANSI standard in 2015. This standard is now undergoing its regular review as required by SPRI’s ANSI procedures. It also comes as part of an ongoing effort to improve roofing industry standards.
Those wishing to participate in the canvass process may contact SPRI at info@spri.org.
