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 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.
