Flat roofing for homes and commercial buildings.

Flat roofs done right

Flat and low-slope roofs are common across the GTA: on additions, garages, modern homes, and commercial buildings of all kinds. They're also where many roofing problems show up first if not installed correctly. Ponding water, failed seams, and compromised flashing are the usual culprits.

North America Roofing specializes in flat-roof systems that actually perform. We use quality membranes, detail every seam and penetration properly, ensure adequate drainage, and stand behind our work. Whether it's a small residential addition or a larger commercial space, we apply the same careful standards.

• Modified bitumen and membrane system options
• Commercial and residential flat roof applications
• Full tear-off, replacement, and new installation
• Leak detection, repair, and resealing services
• Drainage assessment and correction
• Scheduled maintenance and inspection programs

Why choose us for flat roofing

Flat roofs fail at seams, flashing, and drainage points. Water sits, finds weak spots, and works its way in. We install proper membranes and meticulously detail every seam, penetration, and drain so water has nowhere to go but where it should: into the gutters and away from your building.

Our approach includes thorough substrate inspection, correct membrane selection for your specific situation, precision seaming, and verified drainage. We don't cut corners on prep work because that's where most flat-roof failures start.
