Source and coverage

StateLicense downloads IDFPR Professional Licensing data weekly and selects the exact LICENSED ROOFING CONTRACTOR credential description, including sole proprietors and out-of-state mailing addresses. Qualifying-party credentials are separate and excluded. Repeated discipline transactions are consolidated into one identified credential; unknown administrative statuses are not guessed active. The source is attributed to IDFPR under ODbL. Confirm current standing through IDFPR License Look Up.
