Public Records Check
- License Found We found a license number on file for Conrad Roofing Service: 110733, but haven't confirmed its current status directly with the California state licensing board. We recommend verifying it's active and in good standing with the California state licensing board before hiring.
- Registered Corporation The California Secretary of State listed Conrad Roofing Service as Active when we last checked on Jun 19, 2026, registered since 1962. You can confirm it's still current with the California Secretary of State.
- Business Address Conrad Roofing Service's listed address at 663 Walnut St, San Jose, CA 95110 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.
- 1 Credential Conrad Roofing Service holds these manufacturer certifications: Malarkey Certified Pro Contractor. 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 Conrad Roofing Service (Google, Yelp, the Better Business Bureau), 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 5/5 public records for Conrad Roofing Service. The more of a company's record you can check, the more informed your hiring decision.
