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!

We had Lucas and his crew put on a metal roof and it is gorgeous! The crew was clean, quick and friendly! Would highly recommend Cornerstone Roofing!

Great service, talented crew, fair pricing, an all around class act. Cornerstone Roofing is the company you want to hire for your roofing project! Not all roofing companies are the same. Cornerstone stands above them all.

Trevor was honest and straightforward with his pricing quotes and timelines. The job was done professionally and completed on time. Would definitely recommend if you are looking for a reasonably priced, high quality roofing company.

Excellent company. Communicates well, very timely and friendly staff! Loved working with this company.

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.

Working with Cornerstone Roofing was seamless from start to finish. Trevor was great to work with, good communication and quick responses. The guys who installed the room did a great job and cleaned up ALL their mess.

Trevor was great to work with-great communication; on time; work completed as per contract; left area clean & tidy upon completion. Fair price.
