Years Experience
As Newmarket's Owens Corning Platinum Preferred Contractors, we understand the unique roofing challenges faced by homeowners in our growing community. From the historic homes along Main Street to the newer developments in Stonehaven and Upper Canada, our expert crews have installed and repaired countless roofs designed to withstand Ontario's demanding climate.
We've seen firsthand how Newmarket's weather can test even the best roofing systems. That's why we exclusively install premium Owens Corning and GAF roofing products, backed by our lifetime workmanship warranty. Our recent projects in the Armitage area have showcased the durability of Owens Corning Duration shingles, particularly during those harsh winter storms that sweep across York Region.
We provide comprehensive exterior contracting services to homeowners throughout Newmarket and surrounding areas.
