Years Of Experience

Over 40 Years of Protecting Ontario’s Buildings.

Donpar Roofing provides the full range of commercial roofing services across Ontario and the surrounding region. Whether it’s a leak that needs investigating, a roof that’s reached end of life, or a brand-new building going up, our team has the experience to handle it.

Our crews are experienced with all major flat and low-slope roofing systems, including 4-ply built-up roofing (BUR), 2-ply modified bitumen, cold-applied systems, single-ply membranes (TPO, EPDM, PVC), and protective roof coatings. We’ll recommend the right system for your building, your budget, and your timeline.

Our Values

What We Stand For

Everything we do at Donpar Roofing comes back to four principles that have guided this company since the beginning:

Great Service

We respond promptly, show up when we say we will, and go beyond the minimum to protect our clients’ buildings and investments.

Communication

We keep clients informed at every stage — from initial investigation to project completion. No surprises.

Workmanship

We take pride in the quality of our installations and repairs. Every job is done right the first time.

Trust

Many of our clients have worked with us for over 25 years. That loyalty is earned through honesty, transparency, and consistently delivering on our promises
