Top 10 Problems with Asphalt Roofs in Canada

Why traditional shingles fail — and what homeowners should know before replacing their roof again.

Why Asphalt Roofing Falls Short

Asphalt shingles have been widely used across Canada, but they are not designed for long-term performance in harsh climates. Snow, ice, heat, moisture, and wind all contribute to their deterioration.

Understanding the common problems with asphalt roofing can help homeowners make better decisions when choosing a new roofing system.

1. Short Lifespan

Most asphalt roofs last 10–15 years in Canadian conditions before requiring replacement.

2. Granule Loss

Granules wear off over time, reducing protection against UV exposure.

3. Curling & Cracking

Temperature changes cause shingles to warp, crack, and lose effectiveness.

4. Ice Dams

Ice buildup traps water, leading to leaks and structural damage.

5. Wind Damage

Strong winds can lift or remove shingles entirely.

6. Moisture Absorption

Shingles can absorb moisture, leading to deterioration over time.

7. Frequent Repairs

Leaks, missing shingles, and flashing issues require ongoing maintenance.

8. Poor Snow Performance

Snow accumulation adds weight and increases risk of damage.

9. Heat Damage

UV exposure and high temperatures accelerate aging.

10. Re-Roofing Cycle

Homeowners often replace asphalt roofs multiple times over their lifetime.

A Better Alternative

Many homeowners are moving toward metal roofing systems because they offer long-term durability, improved weather resistance, and reduced maintenance compared to asphalt shingles.

Choosing the right roofing system can help avoid repeated costs and provide greater long-term protection.
