GAF Certified Roofing Contractors
U.S. Location Dataset // 16,272

16,272 roofing contractors certified under this manufacturer's program, with street address, phone, website, coordinates and the exact certification tier each holds. GAF is the largest roofing manufacturer in North America and its certification ladder runs Certified, Certified Plus and Master Elite, with the top tier limited to a small fraction of contractors. Certification is the most reliable quality filter available in a trade with very low barriers to entry, which is why distributors, insurers, lead generators and acquirers all use it to qualify. Refreshed weekly from the manufacturer's own contractor locator, so newly certified and lapsed contractors move in and out rather than the list quietly going stale.

All 16,272 records, as published — the complete set rather than a sample. That matters most for coverage and gap questions: put together the same list from partial searches and every location you miss reads as a gap that is not there, so the answer is wrong rather than merely late. Assembling the U.S.-wide coverage by hand also means one query per area against sources that cap what they return per search.
