NRCA began issuing technical bulletins on an as-required basis in 1977 as a means of keeping the roofing industry informed of developing or late-breaking technical issues. In most instances, the bulletins have dealt with matters of special urgency or importance to the industry.
NRCA's technical bulletins are intended as addenda to the current edition of The NRCA Roofing and Waterproofing Manual. Information from past bulletins typically is incorporated into the manual's next edition or is withdrawn because the information no longer is relevant.
To date, NRCA has issued 20 technical bulletins. Relevant information from these bulletins has been included in the fifth edition of the manual.
The following technical bulletins apply to the first three editions of the manual.
