Sonoma County

Trevor and his team were a pleasure to work with. They were very efficient in getting me a roof evaluation and repair estimate, and then getting the work done... right before some big rains! The work they ended up doing cost less than the initial estimate, which also made me very happy. I would definitely work with them again.

Trevor was very professional and available to come out and walk the roof with me so there weren’t any surprises (unlike the 2 other contractors that kept standing me up). The whole process was done quickly and painlessly and I couldn’t be happier with their service. From small basic roofs to large commercial buildings these guys are the best in Sonoma County!

Trevor and his team recently installed a new roof on my home in Rohnert Park. The quality was top notch. Two day project from start to finish on a two-story home. I can’t recommend them enough. Great pricing and great craftsmanship. Thanks Cornerstone Roofing.

Trever was excellent. Cornerstone repaired my roof and they did a quality job with skilled employees at a fair price. I would recommend them to others and use them again myself.

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.

Cornerstone Roofing did an awesome job! They got in and out super fast and completed the job before the rain storm! Super happy, competitive pricing and great craftsmanship. I would recommend them to everyone and will use them again! Thank you to Trevor!

Cornerstone is a family-owned business that performs with professionalism, integrity and excellent service. They have done 3 roofs for our agency and we chose them to do a 4th roof for us. They are a great company, offering good values and quality work. I recommend them with full confidence.
