Public Records Check
- License Found As of Jun 20, 2026, the California state licensing board shows an active license for Acker Roofing: C39 - Roofing 993338. 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 Acker Roofing as Active when we last checked on Jun 23, 2026, registered since 2017. You can confirm it's still current with the California Secretary of State.
- Business Address Acker Roofing's listed address at 975 Detroit Ave ste c, Concord, CA 94518 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 Acker Roofing holds these manufacturer certifications: CertainTeed SELECT ShingleMaster, VELUX Certified Installer. 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.

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

CertainTeed
Reviewers report mixed experiences with Acker Roofing. Several customers describe positive outcomes with roof repairs, leak fixes, and re-roofing projects, noting professional workmanship, timely completion, and reasonable pricing. Multiple reviewers specifically praise an estimator named Dean for his thorough approach and professionalism. Customers also commend office staff responsiveness and the quality of work performed. However, one reviewer reported a negative phone interaction, describing the staff as impatient and dismissive when answering questions about a new roof. Another reviewer, a prospective employee, reported being offered a position, accepting it, and giving notice at their previous job, only to have the offer rescinded via email days before the start date with no explanation or response to follow-up attempts. This reviewer expressed concern about how such treatment might reflect the company's broader business practices.
