Asphalt or metal. It's the roofing question Calgary homeowners wrestle with more than any other. And after the 2024 and 2025 hailstorms, it's become even more pressing.
Both materials are legitimate choices. Neither is universally 'best.'
The right answer depends on your budget, your timeline, and your risk tolerance.
We install both asphalt and metal roofs, and we're direct with homeowners about when each one makes sense. There's no agenda in this guide. We've replaced enough Calgary roofs to know exactly when one option wins over the other, and we'll tell you.
Why This Decision Matters More in Calgary
Calgary sits in 'Hailstorm Alley,' the geographic corridor that produces more damaging hailstorms than almost anywhere else in Canada.
The August 2024 hailstorm caused $3.25 billion in insured losses, the costliest in Canadian history.
In 2025, another significant storm hit during Stampede. Many Calgary homeowners are now on their second or third roof in 15 years.
Your material choice directly determines how your home weathers the next storm and what you'll pay in insurance premiums going forward.
Asphalt Shingles: The Familiar Choice
Asphalt shingles remain the most popular roofing material in North America, covering roughly 75% of residential homes.
They come in two main varieties: 3-tab shingles (flat, uniform appearance, lower cost) and architectural shingles (dimensional, textured appearance, better performance). Modern architectural shingles have largely replaced 3-tab as the standard recommendation.
| Factor | 3-Tab Shingles | Architectural (Standard) | Class 4 Impact-Resistant |
|---|---|---|---|
| Lifespan | 15–20 years | 25–35 years | 30–40 years |
| Cost (installed) | $3.50–$5.00/sq ft | $5.00–$7.50/sq ft | $7.00–$10.00/sq ft |
| Wind resistance | Up to 100 km/h | Up to 180 km/h | Up to 210 km/h |
| Hail resistance | Standard | Standard | Class 4 (highest) |
| Warranty | 20–25 years | 30–50 years | 30–50 years (limited lifetime) |
| Insurance discount | None | Possible (Class 4 only) | 15–25% in some policies |
At ALR, we stopped recommending 3-tab shingles years ago. The cost difference between 3-tab and architectural is typically only $500–$1,000 on a standard Calgary home, but the performance difference is enormous.
For Calgary specifically, we recommend IKO Dynasty or Nordic shingles with Class 4 impact resistance. They're engineered for exactly the conditions we deal with here. IKO also manufactures locally in Calgary, which means the supply chain is reliable and the products are proven against our climate.
Did you know? "After the 2024 hailstorm, we replaced over 300 roofs that season. About 85% were standard asphalt shingles with no impact rating. The homes with Class 4 shingles or metal roofs? Most came through with little to no damage. That number stays with you." — ALR Lead Installer
For Calgary homeowners, the Class 4 impact resistance rating is non-negotiable. This rating means the shingle has been tested against 2-inch steel balls dropped from 20 feet, simulating large hailstones. Many Alberta insurers offer premium discounts of 15–25% for Class 4 rated roofs, which can offset the higher material cost within a few years.
Metal Roofing: The Long-Term Investment
Metal roofing has moved well beyond the corrugated barn-roof image. Modern residential metal roofs come in standing seam panels, metal shingles that mimic traditional slate or shake, and stone-coated steel tiles. They offer exceptional longevity and performance, though at a higher upfront cost.
| Factor | Standing Seam | Metal Shingles | Stone-Coated Steel |
|---|---|---|---|
| Lifespan | 40–70 years | 30–50 years | 40–60 years |
| Cost (installed) | $12–$18/sq ft | $8–$14/sq ft | $9–$15/sq ft |
| Wind resistance | Up to 200+ km/h | Up to 190 km/h | Up to 190 km/h |
| Hail resistance | Excellent | Very Good | Excellent |
| Energy efficiency | High (reflective) | Moderate | Moderate |
| Noise (rain/hail) | Quiet w/ insulation | Quiet w/ insulation | Quiet w/ insulation |
We've seen a significant shift toward metal roofing in the past five years, especially from homeowners who've been through two or three insurance claims in a decade. They start asking: 'Is there something that just won't get damaged?'
Metal is that answer for a lot of people. The upfront cost is real: typically 2 to 3 times more than asphalt. But when you factor in 50+ year lifespan and near-zero hail damage risk, the math often works out.
One thing homeowners commonly ask about metal roofs is noise. With modern insulation and underlayment, a metal roof is actually quieter than asphalt during a hailstorm; the hail bounces off instead of impacting, reducing both damage and sound transmission.
Head-to-Head: The Calgary Comparison
| Factor | Asphalt (Class 4) | Metal (Standing Seam) | Calgary Winner |
|---|---|---|---|
| Upfront cost | $15,000–$20,000 | $24,000–$36,000 | Asphalt |
| Lifetime cost (50 yrs) | $30,000–$40,000 (2 roofs) | $24,000–$36,000 (1 roof) | Metal |
| Hail resistance | Good (Class 4) | Excellent | Metal |
| Snow shedding | Moderate | Excellent | Metal |
| Ice dam risk | Moderate | Low | Metal |
| Insurance premiums | Discounts for Class 4 | Often lowest available | Metal |
| Installation speed | 1 day | 3–7 days | Asphalt |
| Curb appeal | Traditional | Modern / distinctive | Tie (preference) |
| Resale value impact | +$5,000–$8,000 | +$10,000–$20,000 | Metal |
The insurance angle is particularly important in Calgary's market. After the string of major hailstorms in 2020, 2022, and 2024, several Alberta insurers have increased premiums for homes with standard asphalt roofs in high-risk postal codes. Some homeowners in communities like Panorama Hills, Tuscany, and Airdrie have reported annual premium increases of $500–$1,000. A metal roof or Class 4 asphalt roof can bring those premiums back down significantly.
Our Recommendation: It Depends on You
Here's our honest recommendation based on hundreds of Calgary roof replacements:
Choose Class 4 Architectural Asphalt if:
- You're budget-conscious and want the best value per dollar right now
- You plan to stay in your home for 15–25 more years
- You're replacing after a hail claim, and insurance is covering most of the cost
- You want a 1-day installation with minimal disruption
If you go with asphalt, do not install standard non-impact-rated shingles in Calgary. The insurance savings alone from Class 4 make the upgrade worth it. We specify IKO Dynasty or Nordic on virtually every asphalt job we do here.
Choose Metal if:
- You plan to stay in your home long-term (20+ years)
- You're tired of dealing with hail damage claims and want to be done with it
- You want the lowest possible ongoing insurance premiums
- You value the distinctive aesthetic and premium resale positioning
- You're building or completing a major renovation and want a permanent solution
The upfront cost is real. But homeowners who've been through multiple hail events often describe the metal decision as: 'We should have done this the first time.'
The one recommendation we'd never make: installing a cheap, non-impact-rated asphalt roof in Calgary just to save a few hundred dollars. In Hail Alley, that's not saving money; it's deferring a much larger expense.
