Official IDFPR licensed roofing contractor credentials from Professional Licensing Open Data. Illinois does not use this dataset as a statewide general-contractor or home-improvement roster. A qualifying party is a person credential, not a roofing business. Confirm current status on IDFPR License Look Up.

As-of · Open Data rows-updated date
Description LICENSED ROOFING CONTRACTOR is the business class. Source-native ACTIVE plus business=Y yields 4,891 rows and 4,675 distinct license IDs. Status does not conflict on repeated IDs; extra rows carry additional disciplinary action values such as Fine versus Reprimand. A frozen ACTIVE observation is not a live license check.

Qualifying-party credentials are not roofing businesses and are not added to 4,675. This page does not publish a person directory. A person may hold more than one credential. Business-to-party relationships are not inferred from names or addresses.
1,393 roofing rows carry ever_disciplined=Y on 836 distinct license IDs. 1,410 rows have a case number across 789 distinct case IDs. A flag is not a case. A case is not a violation count. An observation is not a conviction. Missing is not a clean history. These are roofing-slice counts, not the master professional-licensing discipline totals.
