Zimmerman's Roofing did a marvelous job when I hired them, most recently. It was my first time working with them, and I really couldn't have been pleased with their excellent service. They did exactly what they said they'd do, when they said they'd do it, and the windows I hired them to replace look fantastic. I really appreciated their reliable, professional nature and would be more than happy to call them, again. They price was good. The work was great. They're definitely first-rate!
