It was a great experience from start to finish. Chris was very professional and came by while the job was being installed to assure that everything was done right. I would definitely recommend them to anybody needing a new roof. My only complaint is minor; I wish they would provide a more detailed and professional invoice! This is not a big thing but a recommendation!
