Since Sentry installed our roof 19 years ago we have not had a single issue with the roof system. On a couple occasions, we needed to make modifications to the roof and Sentry was there to immediately help. Based on my experience as a general contractor and owner I feel this is one of the very best roofing products in the industry and Sentry Roofing has earned my complete confidence with their professionalism and dedication to getting the job done right. I trust Sentry completely and will be having them install my next roof.
