We had a large roof to replace. Gutterman suggested metal. After comparing it with other materials, we decided to go with metal. They worked with us on design - we wanted to make it look like an old fashioned metal roof, so we had them break up the runs in a pattern, which was more work for them, and put the ridge vent on the back side of the roof, use hand crimping, etc. They labored over every detail and did a great job. The final product was superb and the price was very reasonable.
