  Great service, George did my roof in 2024 and was honest about what to expect which is why I contacted him to do the repair on my siding due to a wind storm. I highly recommend him for any job!

  We had a tree fall on our roof which caused roof damage and damage to the interior of our house. George had replaced our roof and vinyl siding in the summer so we called him. He was fantastic again. He is incredibly reliable responsible always responsive to your phone calls. He’s extremely experienced knowledgeable and trustworthy. He is easy to work with. His crew is also excellent. They do a great job. We are very grateful that we hired him in the summer to replace our roof and install vinyl siding on our home because he was a terrific help in dealing with the insurance company and in performing outstanding quality and thorough work both to the roof as well as to the interior of our house, which required ceiling repairs, new window and painting. If you need any of these services, call him, you will be absolutely satisfied.
