I hired Zimmerman's Roofing to do a repair on a slate roof and I am really happy with the work they did. It is a dangerous job and I am happy I wasn't the one to do it. The workman were really great at communicating to me exactly what they would do to fix the roof. I really liked them, and they did great work. They totally knew what they were talking about during the job. Going forward, they are the only people I will be using for my slate roof.
