I called One Call Roofing about a problem leak which turned out not to be a roofing problem at all. The company technician came out, and they did not charge me for the call. They even called a Heating/Air guy to fix my leak and I don't think they made any money off him. I did need them to install a ridge vent on my existing roof, and they did a great job. Donna Pope, my contact person, and the rest of the staff at One Call Roofing are excellent and I definitely recommend them.
