Public Records Check
- License Found As of Jul 10, 2026, the California state licensing board shows an active license for Competition Roofing: C39 - Roofing, B - General Building 638220. 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 Competition Roofing'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 Competition Roofing's listed address at 101 S Loma Pl, Upland, CA 91786 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.
- 2 Credentials Competition Roofing holds these manufacturer certifications: CertainTeed ShingleMaster, Owens Corning Preferred. These show the company met a manufacturer's program requirements and may offer manufacturer-backed warranties, but they aren't independent quality audits. You can confirm current status with the manufacturer.
- Excellent Ratings Across the platforms we identified for Competition Roofing (Google, the Better Business Bureau, Owens Corning), the blended average is 4.9 out of 5, which we label Excellent. This is a plain average of public customer ratings, not a RooferWatch score. A high average reflects past customers' experiences, not a guarantee of yours, so read the underlying reviews and weigh them yourself.
We verified 4/5 public records for Competition Roofing. The more of a company's record you can check, the more informed your hiring decision.
