I met Dave 5 years ago through his snow shoveling business, and he insisted on giving me an inflated quote for the roof replacement. He believes that an underlay is not necessary for a roof. After contacting the shingle manufacturer, without an underlay the manufacturer's warranty is void. Dave conveniently does not tell you this. Instead he pushes his warranty. After thoroughly doing my research, I came across a previous employer of Dave's who suggested that I stay away from Power Roofing because of their low quality and problematic work. Dave uses pressure techniques to try to get you to hire him. He even went up on the roof and destroyed what shingles I had which caused a leak. He stated that the roof was old and what did I expect. He constantly hounded me that the roof had to be replaced by him because he was the best roofer. Dave is so full of himself that he believes all his lies. I eventually, hired a reputable roofer to do the job at a much lower and reasonable price, with a better warranty, and as a bonus I was provided an underlay free of charge. Dave really knows how to run a racket and eventually will get caught in his web of lies. Run don't walk away from Power Roofing!
