As a full-service general contractor, we manage every aspect of your residential project—from planning and permits to the final finishing touches.

Whether you're building from the ground up, renovating a cottage, upgrading a bathroom, or adding a new deck, we bring together skilled trades, reliable project management, and a commitment to quality that shows in every detail.

Mark Hyatt (a recently retired Sergeant of Barrie Police Service) established Hymask Roofing over 20 years ago. Today he employs a team of 15 specialists in Barrie Roofing, basement renovations, deck builds and general contracting to service clients throughout Simcoe County and Muskoka.​

Lifetime Warranties aren't useful if the company you used isn't around any more. Unlike several other temporary businesses in the roofing industry, Mark's history and accountability brings peace of mind to customers knowing they are available and accountable for any post-project concerns.

Our team handles a wide range of services including HVAC, plumbing, electrical, roofing, concrete work, insulation, and more. We also specialize in kitchen and bathroom renovations, home additions, and exterior improvements. With deep roots in Simcoe County and The District of Muskoka, we understand the unique needs of the region—from challenging landscapes to seasonal weather considerations—and deliver solutions that are both practical and built to last.

With one point of contact, clear timelines, and transparent communication, we make the construction or renovation process smooth, efficient, and stress-free. Whether it’s a small upgrade or a full-scale remodel, we take pride in turning your vision into a finished product you’ll love coming home to.
