ROSEMONT, Ill. — With the changing nature of technical information in the roofing industry, the National Roofing Contractors Association (NRCA) has released an updated volume of The NRCA Roofing Manual: Architectural Metal Flashing, Condensation and Air Leakage Control, and Reroofing — 2014. The new volume updates the 2010 version under the same title, serving as a reference for contractors, architects and roof consultants.

The 2014 manual provides best industry practices and standards for the design, materials, installation and repair of roof systems through information gathered by NRCA from knowledgeable, practicing roofing contractors throughout the United States.
