Thought I would give this company a call when I needed my roof replaced and am glad that I did. Set up an appt to get it looked at, Peter showed up on time (most contractors don't show up at all or just drop by whenever). Got a thorough written estimate-which was also different from the others that I got an estimate from. Once I told them to go ahead with it, they were at my house quickly. They had done it on a very windy day, so there was debris all over the place but they did a very good job of cleaning up. And since there was a downpour a day or two after that, I was glad that they did it when they did. Will be getting another roof replaced in the next few years and will be contacting Zimmerman's.
