I'm a local Realtor and have high expectations when working on my home. I had such an amazing experience with the Cornerstone team. Trevor was so transparent and helpful with all of my questions. They got my roof done FAST (2 days) and all of the workers were very nice. I look forward to recommending them to all of my clients in the future.

We enjoyed working with Cornerstone Roofing in Santa Rosa, CA. From their first visit to prepare an estimate to the final clean-up after the project was completed, the company did an excellent job as they also did in their communications and professionalism. I appreciated the crew showing up each morning on time. There was an ample number of men to get our large job done within 3 days. 👍👍

They were great. Intelligent, reasonable, respectful, responsible and got the job done quickly and efficiently. The did what the said how they said they were going to do it.

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!

on budget, on time, clean....everything you want from a contractor

I had two skylights replaced. The two workman that replaced them were fast and very professional. They even went around and inspected all the vent pipes and replaced worn seals. The total cost was time and material that was well below what I was expecting. I have no problem referring these roofers.
