A green roofing resource
With the proliferation of the sustainability movement within the construction industry, green roofing is touted as one of the ways to make roof systems more environmentally friendly. Recognizing this trend, NRCA began developing a green roofing manual in 2004. And in 2007, NRCA published The NRCA Green Roof Systems Manual—2007 Edition.
The manual provides in-depth information about green roof system projects. The information contained in the manual was developed by NRCA member contractors and applies to roofing contractors, designers, manufacturers, and third-party individuals involved with green roof system design and installation.
Although some information is provided about green roof system components, such as drainage layers, moisture-retention layers and filter fabric, if you use the manual, you primarily will find specific information about selection, design and installation of waterproofing membranes appropriate for green roof systems.
