In October, NRCA published an interim update to The NRCA Roofing and Waterproofing Manual, Fifth Edition. At the same time, NRCA published stand-alone versions of certain roof system-specific sections of the manual. A brief overview of these publications follows.
To ensure the manual's fifth edition is as current and complete as possible, NRCA published a 2003 update of interim changes to the manual before the next edition is published, which most likely will be in 2008.
The update consists of 52 new and replacement pages for insertion into the 1,474-page manual, which was published in 2001.
