Cornerstone Slate Roofing did an excellent job repairing a leak in our slate roof, quickly diagnosing the root cause of the problem and thoroughly explaining both the problem and the solution. We are thankful to have found a company so knowledgeable and passionate about something as specialized as slate roofing. Not only did they repair the leak, they also inspected the slates on the rest of the roof and replaced those in suboptimal condition to ensure our roof was well maintained. Cornerstone Slate Roofing was able to fit us in for an appointment promptly, their pricing was very fair, and their communication throughout the process was exceptional. They are reliable and trustworthy. We will definitely call Cornerstone Slate Roofing for any future slate roof maintenance and repairs. See more See less

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. See more See less
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. See more See less
Jay and team do excellent work. We cannot recommend them enough. It can be difficult finding a slate roof professional, but look no further. Our roof needed a cleaning and had a number of missing slate pieces. Jay was super responsive and his estimate was reasonable. He was onsite for most of the work, was super communicative and really knows his craft. We will definitely use Jay and Cornerstone for all our slate roof needs. See more See less
