I had a roof installed last year. It hasn't stopped leaking since it was put in. Watertight doesn't warranty their work, doesn't clean up their work site and leaves roofing nails all over your property. Their 'crews' are made up that morning, mostly of people who have never done a roof before. There lines of shingles are not straight, the flashing they said they installed was not there. I really wish I had never done business with these people.
