I had an Interlock roof installed four years ago to replace an asphalt shingle roof that was continually being damaged by the high winds at my lakefront site. It still looks as good today as when it was installed. Bruce and the Interlock team dealt professionally with the inevitable surprises that arise during any construction project, and ensured the job was completed on time and on budget. I have received many compliments from neighbours and friends, and have no hesitation in recommending Interlock to anyone contemplating a new roof.
