Washington Licensed Roofing Contractors
U.S. Location Dataset // 547

This is the complete licensed universe of roofing contractors in Washington, not a directory of the ones who chose to be listed: every active license the Washington Department of Labor and Industries publishes in its public extract, reduced to one row per licensed firm or individual at an address. 547 records. 547 records carry a separate business name from the licensed individual. Classifications in the file: CONSTRUCTION CONTRACTOR / ROOFING (540), CONSTRUCTION CONTRACTOR / Fireproofing and Coating (7). 114 licensees list an out-of-state address (contractors licensed in Washington but based elsewhere); the state column identifies them so they are one filter to drop. Each record carries the state license number, so it joins cleanly to permit data, insurance certificates and other state files, and the expiration date, so you can target renewals. Buyers use it for distributor and manufacturer territory planning, dealer-program recruitment, insurance and financing prospecting, and roll-up sourcing in a fragmented trade. Association lists such as our ACCA member dataset cover the engaged slice; this covers everyone the state allows to pull a permit. Refreshed weekly from the board's extract.

All 547 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.
