ALEXANDRIA, Va. - An interpretation of the guidelines for the U.S. Green Building Council's LEED Rating System as applied to roofing standards is now available on the Web site of the EPDM Roofing Association (ERA), www.epdmroofs.org.

The bulletin explains how roofing systems can impact the types of voluntary green building standards for commercial applications that are available from the USGBC, including: LEED-NC Version 2.1 for New Construction and Major Renovations; LEED-EB for Existing Buildings; and LEED-CS for Core and Shell Development.

Templates for reporting the attributes of an EPDM roofing system also can be found online at the site's LEED information area. The Bulletin explains to building owners, architects and contractors why the ballasted EPDM roofing system is considered to be a long-term sustainable roofing option. Studies show that an EPDM roof consisting of a waterproofing systems and insulating materials are proven to provide long-term high performance, making EPDM an acceptable membrane for LEED or any other performance based sustainability guideline.
