Expert Certified Commercial, Educational & Industrial Roofers

We can manage the entire roof project from start to finish. In addition, we provide roof surveys, reports and client budgeting as needed.

We provide metal roof restoration and repair to pre-engineered buildings with metal standing seam roof systems. Over time due to snow and ice loads, the seams and fasteners will become loose. We can restore the integrity of the system without any interruption to your office or warehousing. Also, the galvanized coating wears down over time and the metal deck will start to rust. We can also restore the coating.


Due to our extensive experience, we stand by the quality of our work and have no problems offering warranties for up to 15 years. This includes no dollar limit on labour or material. All work is performed to the guidelines of the Canadian Roofing Contractors Association.

We’re a company you can trust and we’ve proven it for over 100 years.

Our promise as a contractor is to build community value into every project while delivering professional expertise, exceptional customers service and quality construction. Our 24/7 Emergency service, If you have any construction and renovation work need, simply contact us.
