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,
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
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.
