My neighbors all love the look of the new roof and we couldn't be happier with the level of service and professional installation. John and his crew were also able to uncover some areas of concern with the roof and replaced damaged sections of the roof to give us the peace of mind that the roof will be good for 30 to 50 years. His crew was very fast at installing both the house and roof on the barn completing the job in 2 days. They also left the jobsite very clean, picking up all the nails and debris. I highly recommend John DeNisco roofing!

UPDATE 8/20/26 I'm…read morevery glad to update this review. Granite State Roofing is one of the most reliable businesses I've encountered. Long story short, the shingles that I chose continued to fail in a very sun-exposed area of my roof. That was my mistake: not going with the shingle recommended. Rob, the owner of this business, always responded promptly when a shingle failed (six times). Each time, he immediately responded via text and came that day to the house to make repairs. In the end--today--he brought his crew to my home and completely reshingled an entire section of my roof at no charge, refusing to share the cost with me. Please see my earlier review for additional details about my experience with Granite State Roofing. This kind of integrity is remarkable.
