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
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.
