I have had a very good experience with Zimmerman's Roofing. I have been using them for five years now, and not too long ago I had them out to do some roof repair work. They did a great job, although the only reason I did not rate their service any higher was because of my last interaction with them, and how it took a very long time for me to get them to get out here and do the work. But all in all, they are good at what they do.
