I am a real estate agent and have used Roof Dr’s in the Sacramento, Solano and Sonoma areas. They show up on time, get reports out quick and are very responsive. I recently had a pest repair that needed quick fixing and they were able to get me a quote and do the work within a couple of days. The quote was less than half of what the pest company had quoted me. They do have a lowest price guarantee of 5% against other bids. I have found their work to be of good quality.
