This was the first time I used Zimmerman's Roofing. I found them on Angie's List and I liked the reviews I saw so I gave them a call. I needed to have new rain gutters and downspouts installed. The crew that came out to do them arrived on time and they were respectful of my property, for the most part. Some of the gutters fell onto the shrubs and trees while they were doing the work. Overall everything worked out. It was a collaborative effort. I mentioned some things that I wanted to see done and they let me know if they could or could not do it so it was a collaborative effort. They were all very courteous and friendly. They cleaned up the yard well when they were done. They did a good job and I would use Zimmerman's Roofing again.
