I first used Zimmerman's Roofing last winter when a branch fell and punctured a hole in my roof. They came out to assess the damage and were able to fix it the same day. I was so impressed with their excellent service that I now have a monthly maintenance agreement with them. I am always happy with the work that they do. The one thing they could improve on is billing, sometimes I don't see the charge on my statement so I have to call them to make sure that they are going to charge me for that month.
