Commercial roofing costs vary significantly based on roof size, material selection, existing conditions, and accessibility. Burlington commercial property owners typically invest between $4 to $12 per square foot for roof replacement, though complex projects with specialized membrane systems or structural repairs can exceed these ranges.
Key Factors Affecting Commercial Roofing Costs
Roofing Membrane Selection
Material choice dramatically impacts both upfront costs and long-term value:
- •TPO Roofing: $5-$8 per square foot installed, offering excellent energy efficiency with heat-reflective white membranes
- •EPDM Roofing: $4-$7 per square foot, proven durability in Ontario's temperature extremes
- •Modified Bitumen: $5-$9 per square foot, superior performance in freeze-thaw conditions
Roof Size and Complexity
Larger commercial roofs benefit from economies of scale, reducing per-square-foot costs. However, multiple penetrations, HVAC equipment, skylights, and complex drainage systems increase labor requirements and material waste factors. Flat roof installation on buildings with difficult access or height considerations requires specialized equipment, affecting overall project pricing.
Tear-Off vs. Roof Overlay
Complete tear-off and disposal of existing roofing materials adds $1.50-$3 per square foot but ensures proper inspection of the roof deck and insulation. Many Burlington commercial buildings benefit from complete roof replacement rather than overlay systems, particularly when addressing moisture damage or improving insulation performance to current building code standards.
Insulation and Energy Performance
Upgrading roof insulation during replacement improves energy efficiency and may qualify for utility rebates. Polyisocyanurate (polyiso) insulation boards, tapered insulation systems for improved drainage, and vapor barriers add $2-$4 per square foot but deliver substantial long-term savings on heating and cooling costs.

Burlington Climate and Building Considerations
Southern Ontario's climate presents specific challenges for commercial roofing systems. Winter temperatures frequently drop below -20°C while summer heat can exceed 30°C, creating expansion and contraction stress on membrane seams and flashings. Annual freeze-thaw cycles accelerate weathering on improperly installed or aging roof systems.
Burlington's proximity to Lake Ontario increases moisture exposure and wind loads, particularly for buildings in exposed locations. Quality installation with proper edge securement, adequate drainage slope, and fully-adhered or mechanically-fastened systems prevents blow-offs and ponding water issues common in this region.
Commercial roofing projects typically require building permits ensuring compliance with Ontario Building Code requirements. Working with licensed and insured commercial roofing contractors familiar with local permit processes prevents costly delays and ensures inspections proceed smoothly.
