Public Records Check
- License Found As of Jul 11, 2026, the California state licensing board shows an active license for Cowan Roofing Inc.: C39 - Roofing 1075580. 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 California state licensing board.
- Registered Corporation Cowan Roofing Inc.'s registered name carries a corporate suffix (LLC or Inc), but we have not matched it to a filing on the California Secretary of State. You can confirm how the business is registered, and its current status, directly with the California Secretary of State.
- Unverified Address Cowan Roofing Inc.'s listed address at 101 W American Canyon Rd, American Canyon, CA 94503 appears to be a unconfirmed address. A roofer using a mailbox isn't necessarily a problem, but it can make the company harder to reach or hold accountable. To reach them in person, ask the contractor for a physical address or confirm one directly.
- 0 Credentials Our automated search didn't find a manufacturer certification for Cowan Roofing Inc.. 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.
- Good Ratings Across the platforms we identified for Cowan Roofing Inc. (Google, Yelp, the Better Business Bureau), the blended average is 4.1 out of 5, which we label Good. This is a plain average of public customer ratings, not a RooferWatch score. A solid average reflects past customers' experiences, not a guarantee of yours, so read the underlying reviews and weigh them yourself.
We verified 3/5 public records for Cowan Roofing Inc.. The more of a company's record you can check, the more informed your hiring decision.

Reviewers report mixed experiences with this roofing company. One customer states they were satisfied with patch work completed a year prior. However, the same reviewer describes frustration with a roof replacement estimate process, noting the company delayed the initial inspection appointment and subsequently failed to deliver a promised estimate over a four-week period despite multiple follow-ups with a staff member named Jim. The reviewer ultimately hired another company for the roof replacement, expressing disappointment about not being able to work with a local business due to these service delays.
