I have used Zimmerman's Roofing twice and have been very pleased both times. They are so good that I have been recommending them. The roof looks great, and the clean-up job is amazing. Nothing was left behind. The guys were on time and treated me very respectfully. It was very easy to have them come out and give me an estimate. I will definitely keep recommending them. I've had nothing but good experiences with them. They have great service.
