I live about 13 miles south west of Cardston, Alberta. This summer I had an “Interlock” roof installed. The fellas doing the work came prepared, worked quickly, cleaned up and hauled away the refuse. They were very professional.

Although we haven’t yet experienced heavy rain, the roof seems no louder in a rainstorm than the asphalt roof. I have and would recommend this roofing to others.

Sincerely,
