Commercial Flat Roof Repair

Water infiltration through commercial flat roof assemblies can jeopardize sensitive machinery, inventory, computer systems, and tenant operations. Windsor Roofing Pros delivers prompt, certified commercial flat roof repairs for industrial facilities, commercial strip plazas, retail stores, warehouses, and multi-unit residential complexes throughout Windsor, Tecumseh, LaSalle, and Essex County.

Common Commercial Flat Roof Failure Points Unlike steep-slope residential roofs, flat and low-slope roofs rely on continuous watertight membranes and positive drainage slopes. Our commercial crews rapidly diagnose and resolve: - **Separated & Open Seams**: Thermal contraction causing heat-welded TPO seams or adhesive EPDM laps to pull apart. - **Ponding Water & Sagging Decking**: Blocked internal roof drains or structural deflection creating standing pools that degrade membrane seals. - **HVAC Curb & Pitch Pocket Breaches**: Vibrating rooftop air conditioning units, gas lines, and conduits causing sealants to pull away from penetration curbs. - **Parapet Wall Flashing Failure**: Deteriorated metal coping cap joints and counter-flashing admitting driving wind and rain behind perimeter membrane terminations. - **Mechanical Punctures & Foot Traffic Damage**: Punctures caused by HVAC technicians dropping tools, flying storm debris, or birds pecking at insulation.

Commercial Diagnostic & Repair Standards 1. **Electronic Moisture Tracing**: We identify trapped moisture beneath the membrane to ensure wet insulation boards are replaced rather than sealed over. 2. **System-Compatible Repair Materials**: We weld genuine TPO to TPO using robotic heat equipment, apply cured EPDM cover tape and primer to rubber roofs, and torch SBS modified bitumen for asphalt membranes. 3. **Internal Drain & Scupper Clearing**: We clear clogged drain strainers and re-clamp compression rings with heavy-duty butyl seals. 4. **WSIB & Commercial Liability Clearances**: Our commercial crews operate under strict safety guidelines with complete WSIB coverage and $5,000,000 in commercial general liability insurance.
