Roof Replacement and Restoration

When It’s Time for a New Roof, We’ll Get It Done Right.

Every commercial roof has a lifespan. When repairs are no longer enough and replacement is the only viable option, you need a contractor with the experience and capability to manage the entire process — from initial assessment through to the final inspection.

Donpar Roofing has been replacing commercial roofs across Ontario for over 40 years. We’ve handled re-roofing projects on every type of commercial, industrial, institutional, and residential building, and we bring that depth of experience to every job.

Assessment & Recommendation

We start with a thorough inspection of your existing roof to understand its condition, identify underlying issues, and determine the best path forward. We’ll recommend whether a full tear-off or an overlay is the right approach for your building.

System Selection

Not every roof system is right for every building. We’ll walk you through the options — from built-up roofing (BUR) and modified bitumen to single-ply membranes (TPO, EPDM, PVC) and cold-applied systems — and help you choose the one that fits your building, your budget, and your long-term goals.

Project Management

We coordinate every aspect of the project, from scheduling and material delivery to crew management and site cleanup. Our clients are kept informed throughout, with regular updates and clear communication at every stage.

Quality Installation

Our crews are experienced, skilled, and committed to doing the job right the first time. We follow manufacturer specifications and industry best practices on every installation.

What We Handle

Full tear-off and replacement of existing roofing systems, including disposal and recycling of old materials. Roof Recovery (overlay) where building conditions permit. Replacement of insulation, vapour barriers, flashings, and drainage components. Coordination with other trades for mechanical, electrical, and HVAC penetrations. All major flat and low-slope roofing systems for commercial, industrial, institutional, and residential high-rise buildings.
