Commercial Roofing Systems We Install
Choosing the right roofing membrane depends on your building design, budget, and long-term maintenance goals. We install and service all major commercial roofing systems:
TPO & PVC Roofing
Single-ply thermoplastic membranes offer excellent energy efficiency and heat-welded seams that resist Ontario weather extremes. White reflective surfaces reduce cooling costs during summer months.
EPDM Rubber Roofing
Durable synthetic rubber membranes proven to withstand freeze-thaw cycles. Cost-effective solution with strong track record in Canadian climates.
Modified Bitumen
Multi-ply system combining traditional built-up roofing reliability with modern polymer technology. Excellent puncture resistance for high-traffic roofs.
Built-Up Roofing (BUR)
Time-tested multiple layer system using asphalt and reinforcing fabrics. Proven longevity for large commercial applications requiring heavy-duty protection.
Emergency Leak Detection & Repair
Commercial roof leaks don't wait for convenient timing. Water intrusion threatens inventory, damages interiors, disrupts operations, and can lead to mold growth if not addressed quickly. Our emergency response team locates leak sources using infrared scanning and moisture meters, then performs immediate repairs to minimize business interruption.
Common leak causes include damaged flashing around HVAC units, compromised parapet walls, clogged drains causing ponding water, and membrane deterioration from UV exposure. We carry materials for all major roofing systems to handle repairs efficiently.

Preparing for Ontario's Climate Challenges
Winter conditions in our region demand roofing systems engineered for thermal cycling. When temperatures swing from -20°C to above freezing repeatedly throughout winter and spring, roofing materials expand and contract. Proper installation techniques—including adequate fastening patterns, proper seam overlap, and quality flashing details—prevent these movements from compromising your roof's integrity.
We also address drainage design carefully. Flat and low-slope roofs must have proper slope to drains, and those drains need protection from ice damming. Ponding water that freezes and thaws accelerates membrane degradation and creates leak pathways.
