This guy thinks he is some amazing person, with his great presentation, yet the roof he installs does not last, he is not approved to provide a warranty and he has no factory training. If i didn't know better, he would be odd job bob. gives everything a try, but hes no good at anything. sure he has been in business for a while, doing siding/doors/windows/roofs/etc... i don't know about you, but i don't hire an electrical to rebuild my car and i wouldn't recommend hiring this tart to do my roof either! ask for the proper paper work during your project to protect yourself!
