  Cornerstone Roofing is top-notch! Trevor and his crew provide the highest work of quality. They are insured and provide excellent service. Call them, you will be happy you did. And, did I say they offer reasonable prices.

  Trevor and his team did an excellent job roofing, my mother's manufactured home. He recommended color for the roofing and providing a custom flashing between the roof and carport awning to make it waterproof. All at a reasonable cost. I highly recommend his company.

  Working with Trevor at Cornerstone Roofing for my home reroof was a most enjoyable experience. From the first site meeting through contract procurement and installation Trevor and his team were present, transparent and responsive. The quality of installation was very good, and they coordinated directly with the solar installer to ensure efficient and effective installation. One minor callback issue was handled immediately. I would definitely use them again

  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 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.
