Years Experience
As Innisfil's trusted roofing experts, we understand the unique challenges that Lake Simcoe's waterfront climate poses to local homes. From the harsh winter winds sweeping across Alcona to the summer humidity affecting homes in Stroud, your roof needs to stand up to everything Mother Nature throws at it.
Our status as Owens Corning Platinum Preferred and GAF Certified Contractors means we bring the highest level of expertise to every project, whether it's a complete roof replacement in Cookstown or emergency repairs in Lefroy. We've specifically chosen roofing systems that withstand our unique local conditions – including Owens Corning's Duration® series shingles with WeatherGuard® technology, perfect for protecting against those fierce lake-effect snow and ice we experience along the shoreline.
We provide comprehensive exterior contracting services to homeowners throughout Innisfil and surrounding areas.

What sets us apart is our commitment to quality craftsmanship. Unlike many contractors, we never use subcontractors – every installation is completed by our own highly trained crews who live and work right here in Innisfil. This allows us to maintain strict quality control and back every project with our lifetime workmanship warranty. Just ask our customers in Alcona, where we've completed dozens of installations that have weathered multiple harsh winters without a single callback.
We're particularly proud of our emergency response service. When last winter's severe storm damaged several roofs in the Stroud area, our team was on-site within hours, providing temporary repairs and following up with permanent solutions. That's the kind of reliable service that's earned us our top-rated status on Google and countless referrals from satisfied homeowners throughout Innisfil.
