      They delivered a beautiful slate roof that enhanced the beauty and value of my home. Thanks for the great service.

      Jay from Cornerstone roofing was great to work with. We have an old slate roof that hadn't been maintained for several years. He was very responsive with an estimate (and he gave us a very reasonable price), and once we agreed on the work to be done, he and his team started promptly and were very communicative throughout the process. Will definitely be using Cornerstone Roofing if we need more roof work done.

      I don't usually write these reviews but after the way Cornerstone went above and beyond for me I promised them that I would. Service was professional and friendly from start to finish. I had a property I was rehabbing and had never run into a slate roof before. Cornerstone got me all fixed up and the price was more than fair. 10/10 would recommend to anyone.
