Public Records Check
- License Found As of Jun 19, 2026, the California state licensing board shows an active license for Costa Roofing: C39 - Roofing 1061541. 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 The California Secretary of State listed Costa Roofing as Active when we last checked on Jun 19, 2026, registered since 2018. You can confirm it's still current with the California Secretary of State.
- Business Address Costa Roofing's listed address at 16206 Hawthorne Blvd, Alondra Park, CA 90260 appears to be a business 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.
- 2 Credentials As of Jun 13, 2026, Costa Roofing holds these manufacturer certifications: GAF Authorized / GAF Certified, GAF GoldElite (Commercial). 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 Costa Roofing (Google, Yelp, GAF), the blended average is 5.0 out of 5, which we label Excellent. This is a plain average of public customer ratings, not a RooferWatch score.
