TRI Alliance and WSRCA technical committees, along with valuable input from the roofing community, revised the previous 2010 edition of this manual to create the 2015 edition. TRI Alliance and WSRCA submitted this manual for formal review and issuance of an IAPMO Uniform ES Evaluation Report (ER-2015) to help provide a stronger foundation to formal practices and recommendations included.
