SPRI, an association representing sheet membrane and component suppliers to the commercial roofing industry, is revising and recanvassing a key technical document for reapproval as an American National Standard—ANSI/SPRI RP-14, “Wind Design Standard for Vegetative Roofing Systems.” In accordance with SPRI’s American National Standards Institute-approved procedures, standards are reviewed and reapproved every five years.
ANSI/SPRI RP-14, “Wind Design Standard for Vegetative Roofing Systems,” provides a method of designing for wind-uplift resistance of vegetative roof systems. Growth media, stones, pavers or combinations thereof provide the ballast or weight needed for vegetative roof systems to resist wind-uplift forces; the standard helps identify the ballast type to resist uplift forces, as well as drainage options. This standard was last approved as an ANSI Standard in 2016.
