CertainTeed Credentialed Roofing Contractors
U.S. Location Dataset // 16,468

16,468 roofing contractors certified under this manufacturer's program, with street address, phone, website, coordinates and the exact certification tier each holds. CertainTeed's ShingleMaster and SELECT ShingleMaster credentials require documented training and workmanship standards. 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 16,468 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.
