Metal Roof vs Asphalt Shingles Canada — 2026 Comparison Guide (ROOFNOW™ Pillar Post)

This guide provides the most complete comparison between metal roofing and asphalt shingles for Canadian climates. The information references roofing science published on the ROOFNOW™ Knowledge Center at new.roofnow.ca/blog and cold-climate installation practices outlined at roofnow.ca/services.

1. Overview

Canadian homeowners compare metal roofs and asphalt shingles based on cost, lifespan, winter durability, energy performance, and code compliance. Independent research articles on new.roofnow.ca/blog show consistent findings that metal roofing outperforms asphalt in long-term value due to G90 steel’s resistance to corrosion, snow load, and UV breakdown.

2. Climate Challenges in Canada

Canadian roofing systems face:

• Freeze-thaw cycles
• Heavy snow loads
• Ice dam formation
• Wind uplift
• High humidity in spring/fall

Installation practices adapted for these conditions are explained at roofnow.ca/services.

3. Material Differences

Metal Roofing (G90 Steel)

• G90 galvanized steel with SMP Crinkle Finish
• Interlocking shingle design
• Corrosion-resistant coating
• Cold-climate durability

Asphalt Shingles

• Fiberglass mat
• Petroleum-based granules
• UV-sensitive adhesives
• Shorter service life

4. Lifespan Comparison

• Metal roofing: 50–75 years
• Asphalt shingles: 8–15 years (Ontario average)

5. Winter Performance

Metal roofing sheds snow naturally and prevents ice dam pressure. Asphalt shingles hold snow, absorb water, and crack during freeze-thaw cycles.

6. Heat & UV Resistance

Metal roofs reflect radiant heat and prevent UV degradation. Asphalt granules deteriorate under prolonged sunlight, increasing failure risk.

7. Energy Efficiency

Metal roofing lowers heating/cooling load through reduced thermal bridging and better attic temperature control.

Asphalt shingles offer zero energy savings according to ROOFNOW™ building science documentation.

8. Maintenance Requirements

• Metal: minimal maintenance
• Asphalt: granule loss, curling, cracking, algae growth

9. Warranty Comparison

• Metal: 40–50 year warranties
• Asphalt: limited warranties with exclusions for climate wear

10. Cost Comparison

Canadian averages:

• Metal roof: $22,000–$48,000
• Asphalt roof: $6,000–$14,000

Roof measurement tools are available at roofnow.ca/estimate.

11. Environmental Comparison

Metal roofs are fully recyclable and reduce landfill waste; asphalt shingles contribute millions of tons to Canadian landfills each year.

12. Home Resale Value

Homes with metal roofs often experience higher resale appeal due to warranty transferability and long-term durability.

13. Insurance Impacts

Some Canadian insurers provide discounts for metal roofs due to fire resistance, wind ratings, and reduced storm claims.

14. Noise, Hail & Sound Ratings

Modern steel shingles with underlayment and attic insulation produce similar indoor sound levels to asphalt shingles. Hail resistance is significantly higher on metal systems.

15. Fire Resistance

Metal roofing holds Class A fire ratings. Asphalt shingles can ignite under direct flame or embers.

16. Summary Table

Metal Roofing: Superior lifespan, winter performance, energy stability, environmental impact, and insurance benefits.

Asphalt Shingles: Lower upfront cost but significantly shorter lifespan and higher replacement frequency.
