Certified Commercial Roofing Across the Greater Toronto Area
A residential shingle replacement and a commercial roofing project share the same basic principle: keep water out of the building, but almost nothing else about how they are executed. Commercial roofing systems cover larger surface areas, operate under different load and drainage requirements, use materials that residential roofers rarely work with, and need to be completed on timelines that account for the operational continuity of the business occupying the building below.
Roofing Repairs Dun-Rite Inc. provides commercial roofing contractor services across the GTA with 42 years of experience across both residential and commercial systems. Brad Ellis oversees every commercial project directly, bringing the same hands-on approach and material knowledge to a warehouse roof in Scarborough that he brings to a residential shingle installation in North York. No subcontracting, no handoffs, no corners cut because the building is commercial rather than residential.

Commercial Roofing Services We Provide
Commercial roof installation for flat and low-slope systems across the GTA covers the full range of membrane systems appropriate for commercial applications. EPDM commercial roofing installation provides a single-ply rubber membrane system that handles thermal movement, UV exposure, and ponding water conditions better than many alternative systems at its price point. Our EPDM commercial roofing service covers full installation from deck preparation through to membrane application, seam welding, and perimeter detail finishing. Commercial roof installation company work for modified bitumen and built-up roofing systems follows a similarly thorough process where material selection is matched to the drainage conditions, occupancy type, and maintenance access requirements of the specific commercial property. We take the time to understand how the building is used and who will be responsible for ongoing maintenance before specifying a system, because the right system for an owner-occupied building is not always the right system for a multi-tenant property with limited roof access.
- LOCAL CRAFTSMANSHIP
Commercial Roof Repair
Commercial roof repair addresses the specific failure patterns commercial roofing systems develop over time. Seam separation at EPDM lap joints, blister formation in modified bitumen surfaces, gravel displacement on built-up systems, and flashing failure at roof penetrations and parapet walls are all repair conditions our team handles regularly across GTA ommercial properties. Commercial roof repair service response is managed around the operational requirements of the building wherever possible, with scheduling that minimizes disruption to the business below and emergency response available for active water entry situations that cannot wait for a scheduled appointment. When a commercial building has an active leak, every hour of delay carries a cost that goes beyond the repair itself, and our team responds to commercial emergency calls with that urgency in mind.
Best Commercial Roofing Standards
Every commercial project Roofing Repairs Dun-Rite Inc. completes is held to the same standards applied to our residential work: full material documentation, certified installation procedures, and a final inspection by Brad Ellis before the project is closed. Best commercial roofing outcomes come from the same fundamentals that produce good residential outcomes: honest assessment, proper preparation, quality materials, and workmanship that does not cut corners because no one is watching from the street.
