NRCA develops The NRCA Roofing Manual as a best-practices guide for roof system installations on buildings and other structures in North America. The manual's guidelines are based on the recommendations of NRCA's Technical Operations Committee and NRCA's Manual Update Committee. NRCA's Technical Operations Committee establishes NRCA's technical programs and priorities. NRCA's Manual Update Committee is responsible for updating The NRCA Roofing Manual. The committees are composed of knowledgeable, practicing roofing professionals.
NRCA's best-practice approach generally is more conservative than building codes' minimum requirements and is consistent with or more conservative than manufacturers' recommendations. Building codes provide minimum legal requirements for construction, and manufacturers' recommendations generally provide a level of quality construction necessary to obtain a manufacturer's warranty. The NRCA Roofing Manual should be viewed as a guide and not a design or installation standard or code.
