I was very happy with Zimmerman's Roofing. They installed windows and a door for me and they did a great job. They showed up on time, finished the work and had everything cleaned up before they left. The door and windows look very nice and I am thoroughly pleased with it all. Their pricing was fair. The workmanship was very good. The installers were efficient and communicative. They had to come back to finish the painting in a couple of days but they told me when they were coming back and they were there on time to complete it. I've never used them before but I'd definitely call them again. Go Zimmerman's!
