Zimmerman's Roofing did an excellent job. They installed new roofing for me and from what I could tell, they did quality work. Justin, a representative who came out to assess the job, was very thorough and excellent to work with. I was not there when they did the work, but there were no problems and the process went very smoothly so I would say that they did a great job. They finished within a couple weeks and I am satisfied with everything they did. This was my first time using them and I would definitely use them again in the future.
