      Excellent slate roofing work! The copper flashings are expertly done, and the crew made sure the property was perfectly clean after finishing. Five stars!

      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.
