Public Records Check
- License Found As of Jul 10, 2026, the Illinois state licensing board shows an active license for K.N.Z Construction: 104019100. An active license means the state currently authorizes this contractor to do this work. It doesn't speak to the quality of their work or their current insurance. License status can change, so you can confirm it's still active anytime with the Illinois state licensing board.
- Missing Corporation Our automated search didn't find a registered business entity for K.N.Z Construction with the Illinois Secretary of State. That doesn't mean the company isn't legitimate. Many roofers operate legally as sole proprietorships, which don't require registration, and a registered business can be filed under a different name, formed in another state, or created too recently for us to match. To confirm how the business is structured, ask the contractor or search the Illinois Secretary of State directly.
- Residential Address K.N.Z Construction's listed address at 113 Mallard Ln, Bay View Gardens, IL 61611 appears to be a residential address. This means the company operates from a real, locatable address rather than a mailbox or PO box, which can make it easier to reach them or resolve issues. Many roofers legitimately work from a home address, so this doesn't speak to the quality of their work, license, or insurance.
- 0 Credentials Our automated search didn't find a manufacturer certification for K.N.Z Construction. Many reputable roofers aren't certified by any manufacturer, often by choice, so this isn't a sign of a problem. If a manufacturer-backed warranty matters to you, ask the contractor which certifications they carry.

This is a plain average of public customer ratings, not a RooferWatch score.
