Roofing 101 — What Every Canadian Homeowner Should Know
Understand roofing materials, costs, lifespan, insurance claims, and how to choose the right roofer for your project.
Roofing Materials Comparison
Asphalt Shingles
Pros: Most affordable, widely available, easy to install and repair. Available in many colours.
Cons: Shorter lifespan than alternatives, vulnerable to high winds and ice dams.
Best for: Most Canadian homes, budget-conscious homeowners.
Metal Roofing
Pros: Extremely durable, energy efficient, sheds snow well, fire resistant.
Cons: Higher upfront cost, can be noisy in rain/hail, requires specialized installers.
Best for: Homeowners wanting long-term value, snowy climates, modern aesthetics.
Cedar Shake
Pros: Beautiful natural look, excellent insulation, ages gracefully.
Cons: Requires regular maintenance, fire risk (unless treated), vulnerable to moss/rot.
Best for: Heritage homes, cottage country, homeowners who value natural aesthetics.
Slate
Pros: Longest-lasting roofing material, fireproof, stunning appearance, zero maintenance.
Cons: Very expensive, extremely heavy (may need structural reinforcement), fragile to walk on.
Best for: High-end homes, heritage buildings, homeowners investing for the long term.
Flat Roof (TPO/EPDM)
Pros: Ideal for low-slope roofs, energy efficient, cost-effective for commercial buildings.
Cons: Prone to pooling water, requires proper drainage, limited aesthetic options.
Best for: Commercial buildings, low-slope residential roofs, modern flat-roof designs.
What Does a Roof Cost in Canada?
Roof pricing in Canada depends on several factors: roof size (measured in squares — 1 square = 100 sq ft), pitch/steepness, material chosen, number of layers to remove, and your local labour market.
A typical 1,500 sq ft bungalow with asphalt shingles costs $8,000–$12,000 to re-roof. A two-storey home with steep pitch could run $12,000–$20,000. Metal and premium materials cost significantly more but last 2–3x longer.
Always get at least 3 written quotes. Beware of prices that seem too good to be true — they usually are. Quality installation is more important than material choice for long-term performance.
Insurance Claims Process
Home insurance in Canada covers roof damage from sudden events: windstorms, hail, fallen trees, fire, and ice storms. It does not cover gradual wear and tear, age-related deterioration, or lack of maintenance.
If your roof is damaged in a storm: (1) Document the damage with photos and video immediately. (2) Prevent further damage by tarping if safe to do so. (3) File a claim with your insurer within 24–48 hours. (4) Get your roofer to provide a detailed damage report and repair estimate for the adjuster.
Your deductible typically ranges from $500–$2,500. The insurer will send an adjuster to assess the damage before approving repairs. Choose a roofer experienced with insurance work — they know what adjusters look for.
When to Repair vs. Replace
Repair Makes Sense When:
- - Roof is under 15 years old
- - Damage is localized to one area
- - A few shingles are missing or cracked
- - Minor flashing issues around vents
- - Small leak caught early
Replace When:
- - Roof is 20+ years old
- - Widespread shingle curling or granule loss
- - Multiple leaks in different areas
- - Sagging or structural concerns
- - Repair costs exceed 30% of replacement cost
Best Time to Roof in Canada
The ideal roofing season runs from late May through October. Asphalt shingles need temperatures above 10°C to seal properly. Metal and flat roofing can be installed in cooler conditions but still require dry weather.
Book your spring or summer roof replacement in January–March for the best pricing and availability. Roofers are busiest from June through September — scheduling 2–3 months ahead is common.
Emergency repairs can be done year-round. A good roofer will tarp and temporarily seal damage in any weather to prevent further interior damage until permanent repairs can be made.
