11 roofing companies in Decatur that passed our license check
How this list was made. Nobody pays to be here, and we do not rank by star ratings because we do not have review data we trust. A roofer makes the list for one reason: we looked them up on IDFPR license lookup and found an active license or registration.
11 of the 17 roofing companies we list in Decatur passed. They are in alphabetical order, so the first name is not the “winner”. How we verify.

What we could not check
A license shows a roofer is allowed to work. It does not show how well they work. Three things are on you before you sign:
- Insurance. Ask for a certificate of insurance with general liability and workers’ compensation, then call the insurer and confirm it is current.
- Warranty in writing. Get the workmanship warranty (years and what it covers) on the contract, separate from the shingle maker’s warranty.
- Recent local jobs. Ask for two addresses in Decatur roofed in the last year and drive by.
Roofing licenses in Illinois
Illinois licenses roofing specifically under the Roofing Industry Licensing Act — the Department of Financial and Professional Regulation (IDFPR) issues the license and publishes every roofing contractor license it has issued — you can look up any roofer yourself on IDFPR license lookup. Verified badges in Illinois mean an IDFPR roofing contractor license the state currently lists as active.
