Cornerstone Roofing Inc.
Cornerstone Roofing Inc. provides residential roofing, roof repair, and new roof installation throughout Santa Rosa, CA. Our second-generation family has roofed Sonoma County homes since 2006, and every crew we send out works under a California license and full bonding. We inspect the deck, flashing, and drainage before recommending work, so homeowners understand what the roof actually needs. Our shingle systems are chosen for Northern California weather, holding up through wet winters and long summer heat. We trace leaks to the source instead of patching symptoms, and we put pricing in writing before the first nail goes in. Nearly two decades of finished projects across the North Bay stand behind that work.
Customer's reviews
It was such a pleasure to work with Trevor and the team at Cornerstone. My daughter inherited her Dad’s home in2022 and had a complete remodel done. The storms hit hard and the roof was leaking. Cornerstone replaced the roof which was all Spanish tile. They did such a wonderful job that I reached out to them again when my home’s roof was leaking into my kitchen earlier this year. They got the roof replaced on my house and my detached garage quite quickly and reasonably. I so appreciated that they left their work areas clean every day. If I ever need a replacement for any of the other homes, they will be the first ones I call, but hopefully not anytime soon. Highly, highly recommend!

I cannot recommend Trevor and the team at Cornerstone Roofing highly enough. We were dealing with two substantial leaks in our roof, and the level of service we received was truly exceptional.
Before they were even scheduled to replace the entire roof, Trevor went above and beyond by coming out right before a major storm to provide temporary patches. It gave us immense peace of mind during a stressful time.
Furthermore, once he saw the extent of the damage, he took advantage of a break in the weather to move our roof replacement up—getting the job done right before the massive December storms hit Bodega Bay.
To top it off, their pricing was very competitive. If you are looking for a roofing company that is professional, responsive, and genuinely cares about the quality of their work, look no further. I’m already recommending them to all my neighbors and friends.

I own a house at The Sea Ranch that needed a roof replacement. I spoke to Trevor and inquired if they serviced the area. Luckily they did! They gave me a reasonable quote and "they say what they do and do what they say" which is somewhat rare these days. I never recommend any contractor if they're not "5 stars" and I highly recommend Cornerstone Roofing for your roof repair or replacement. Their prices are fair and their work is exemplary. I have already recommended them to one of my neighbors and I hope they use them. I'm glad I did and you will be too.
