Commercial Roofing Systems We Install

Every commercial building has unique roofing requirements. We specialize in low-slope and flat roofing systems designed for the structural demands and weather exposure common to this region:

• • TPO and PVC Single-Ply Membranes: Energy-efficient, heat-welded seams provide superior waterproofing for flat and low-slope applications
• • EPDM Rubber Roofing: Durable membrane systems with excellent thermal cycling resistance for Ontario's freeze-thaw conditions
• • Modified Bitumen: Multi-layer systems ideal for high-traffic roof areas and mechanical equipment access
• • Built-Up Roofing (BUR): Time-tested tar and gravel systems for maximum durability
• • Metal Roofing Systems: Standing seam and R-panel installations for long-term performance

Climate Considerations for Commercial Roofs

Ontario's weather patterns place specific demands on commercial roofing systems. Winter temperatures regularly drop well below freezing, while summer heat can push surface temperatures beyond 70°C on dark membranes. This thermal cycling creates expansion and contraction that stresses roof membranes, flashing details, and penetration seals.

Ice damming, snow load management, and proper drainage are critical concerns. We design roof slopes and drainage systems to prevent ponding water, which accelerates membrane deterioration and increases the risk of leaks. Our installations include proper insulation to minimize heat loss and reduce ice dam formation along roof edges and drainage areas.

Repair and Maintenance Programs

Regular maintenance extends roof lifespan and prevents minor issues from becoming costly emergency repairs. Our commercial maintenance programs include:

• • Seasonal inspections following winter and storm events
• • Drain and scupper cleaning to ensure proper water flow
• • Membrane patching and flashing repairs
• • Detailed documentation for warranty compliance and building records

Building Code and Permit Compliance

Commercial roofing projects in Oshawa require adherence to Ontario Building Code requirements and local permitting processes. We handle permit applications and ensure all work meets current code standards for fire rating, wind uplift resistance, and structural loading. Our installations are performed by trained technicians, and we provide all necessary documentation for building department inspections and your facility records.
