Years Experience
As Whitby's Owens Corning Platinum Preferred Contractors, we understand the unique roofing challenges faced by homeowners across our diverse community – from the lakeside homes in Port Whitby dealing with moisture and wind to the newer developments in Brooklin requiring robust protection against Ontario winters.
Our in-house crews have installed hundreds of roofing systems throughout Whitby's neighborhoods, including recent projects in Pringle Creek and Downtown Whitby. We've seen firsthand how Lake Ontario's weather patterns can impact roofing materials, which is why we exclusively install Owens Corning and GAF roofing systems designed to withstand our specific climate challenges.
We provide comprehensive exterior contracting services to homeowners throughout Whitby and surrounding areas.
