Our house lost a bunch of shingles during the recent wind storm. We had originally used Gencan Roofing and Waterproofing ltd to install the shingles about 8 years ago. Without any hesitation they were able to find our matching shingles and had the repairs done within 48 hours of the storm. Unbelievable Service and they did this repair at no cost. I would highly recommend Gencan Roofing and Waterproofing ltd as they have great customer service and workmanship.
