Roofing needs vary significantly between residential and commercial properties. In Canada’s demanding climate — with snow loads, ice, wind, hail, and freeze–thaw cycles — understanding these differences helps owners make better decisions about maintenance, repairs, and replacement.

This guide explains the key differences between commercial and residential roofing in Canada and what property owners should know before hiring a contractor.

Roof Design and Structure Differences

Residential Roofing

Residential roofs are typically:

  • Steep-sloped
  • Smaller in total area
  • Designed to shed snow and rain quickly

Common designs include gable, hip, and valley roofs, often with multiple penetrations like chimneys and skylights.

Commercial Roofing

Commercial roofs are usually:

  • Flat or low-slope
  • Much larger in surface area
  • Engineered to support equipment and foot traffic

They often include rooftop HVAC units, drains, scuppers, and parapet walls, which require specialized detailing.

Roofing Materials Used in Canada

Residential Roofing Materials

Most homes use:

  • Asphalt shingles
  • Metal roofing
  • Cedar shakes or synthetic alternatives

These materials are selected for curb appeal, affordability, and snow-shedding ability.

Commercial Roofing Materials

Commercial buildings commonly use:

  • TPO, PVC, or EPDM membranes
  • Modified bitumen (SBS)
  • Built-up roofing (BUR)
  • Metal systems on certain facilities

These systems prioritize durability, waterproofing, and ease of maintenance over appearance.

Installation Complexity and Labour

Residential Roofing

Residential projects are usually:

  • Completed in a few days
  • Less equipment-intensive
  • Easier to access

However, steep slopes and complex layouts can still pose safety challenges.

Commercial Roofing

Commercial roofing often requires:

  • Larger crews
  • Safety plans and fall protection
  • Material hoisting equipment
  • Longer project timelines

Improper installation on a commercial roof can lead to widespread leaks and business disruption.

Maintenance and Inspection Needs

Residential Roof Maintenance

Homeowners typically need:

  • Visual inspections after storms
  • Gutter cleaning
  • Periodic repairs
  • Inspections every 1–2 years

Small issues can escalate quickly if ignored.

Commercial Roof Maintenance

Commercial roofs require:

  • Scheduled inspections (often twice per year)
  • Drain and scupper cleaning
  • Detailed condition reports
  • Preventative maintenance programs

Regular maintenance is critical to extending roof lifespan and avoiding emergency repairs.

Cost Differences and Budgeting

Residential Roofing Costs

Residential roofing costs are influenced by:

  • Roof size and slope
  • Material choice
  • Tear-off requirements
  • Accessibility

While less expensive than commercial projects, poor workmanship can still be costly long-term.

Commercial Roofing Costs

Commercial roofing costs depend on:

  • Square footage
  • Roofing system type
  • Insulation and drainage design
  • Building occupancy requirements

Commercial owners often budget for long-term performance rather than lowest upfront cost.

Insurance and Liability Considerations

Residential Properties

Home insurance typically covers:

  • Sudden storm damage
  • Wind or hail-related issues

Coverage may be reduced for aging roofs or poor maintenance.

Commercial Properties

Commercial insurance often requires:

  • Regular inspections
  • Maintenance documentation
  • Professional reports

Failure to maintain the roof can impact coverage and claims.

Choosing the Right Roofing Contractor

Not all roofers handle both residential and commercial work. Each requires different skills, equipment, and experience.

Before hiring, confirm:

  • Experience with your property type
  • Knowledge of Canadian building codes
  • Proper insurance and safety compliance
  • Clear, itemized estimates
