Cornerstone Roofing Inc.

Cornerstone Roofing Inc. is a second-generation, family-owned roofing contractor in Santa Rosa, CA, providing residential roof installation and repair across Sonoma County. Every crew works under a California license and full bonding.

We inspect the deck, flashing, and drainage before recommending work, and we trace each leak to its source instead of patching symptoms.

Pricing is put in writing before work begins, backed by nearly two decades of finished projects across the North Bay.
