Interlock had installed other metal roofing in our neighborhood. We were impressed with what we saw and decided to use their services for our home. The price was very competitive and the end result looks great. The installer was professional, courteous and efficient. We are very impressed by Interlock and would recommend them for anybody looking to install a metal roof. Positive: Quality, Professionalism, Value Services: Roof installation
