Years Experience
As Welland's trusted Owens Corning Platinum Preferred Contractors, we understand the unique roofing challenges faced by homeowners in our canal district community. From the historic homes in Downtown Welland to the waterfront properties along Canalside, our experienced crews have protected local homes with premium roofing solutions for over two decades.
Our expertise as GAF Certified Contractors becomes especially valuable when dealing with Welland's diverse weather patterns. The moisture from the canal system and intense seasonal changes can take a toll on roofing materials. That's why we exclusively install Owens Corning Duration® shingles with WeatherGuard® technology, specifically engineered to withstand our harsh Ontario winters and humid summers.
We provide comprehensive exterior contracting services to homeowners throughout Welland and surrounding areas.

This allows us to maintain strict quality control and back every installation with a lifetime workmanship warranty. When you call (226) 799-4975, you're connecting directly with local roofing experts who understand Welland homes inside and out.
