ROSEMONT, IL—Keeping the industry up to date on roofing's changing technologies, the National Roofing Contractors Association (NRCA) has released The NRCA Roofing Manual: Membrane Roof Systems – 2015.

The new guide updates the 2011 volume of the same title, serving as a reference for contractors, architects and roof consultants.

The 2015 manual provides best practices and technical information about the design, materials and installation techniques for membrane roof systems used in low-slope applications.

The NRCA manual focuses on membrane roof systems used in low-slope applications. Among the many brands now on the market is GAF's Self-Adhering Roofing System.

Also included is information about roof decks, air and vapor retarders, rigid board insulation, roof membranes, fasteners, surfacing, accessories, roof system configurations and roof re-coverings.

A new format facilitates proper product and material selection, according to NRCA. The first chapter contains a selection of roof system configurations. Each of those has a list of applicable roof components with references on where to find additional information in the manual.

Also included are 203 construction details for built-up roof (BUR) membrane, polymer-modified bitumen, liquid-applied, EPDM and other single-ply membrane roof systems.
