Understanding the key factors that influence commercial roofing prices
Square footage is the primary cost driver. Complex shapes with multiple penetrations, skylights, or HVAC units increase labor and materials.
TPO, PVC, EPDM, modified bitumen, and metal each have different price points and lifespans. Premium materials cost more upfront but last longer.
Tear-off and disposal of existing materials adds cost. Some roofs can be recovered, saving on removal expenses.
Adding or upgrading insulation improves energy efficiency but increases project cost. R-value requirements vary by building code.
Building height, crane requirements, and distance from suppliers affect pricing. Urban locations may have higher labor costs.
Peak roofing season (summer) may have longer wait times. Off-season projects sometimes offer cost savings.
If your roof is aging, leaking, or storm-damaged, it may be time for a replacement. At CMP Roofing, we specialize in residential and commercial roof replacement in Calgary, offering durable, energy-efficient roofing systems designed for Alberta’s harsh climate.
As of 2025, the average roof replacement cost in Calgary ranges between CAD $8,000 and $18,000 for homes, while commercial roofing systems typically range from CAD $7 to $22 per sq ft.
Every project we handle includes a free inspection, detailed estimate, and manufacturer-backed warranty.
