We ultimately did not hire Peterson, but I would strongly consider them for future work. We called several companies for estimates to repair or replace a flat roof on an addition to our home. Peterson was the first company to respond, the first company to come out to the house, and the first to provide an estimate. I was impressed that they provided 3 estimates: 1) to simply repair a damaged/leaking area, 2) to put a new roof over the existing roof, and 3) to tear off and replace the existing roof. They were very responsive, and communicated clearly and quickly by phone and email.
