Calgary Hail Damage
Hail Damage Roof Repair vs Replacement in Calgary
How to assess hail damage, when repair is enough, when replacement is necessary, and how to navigate an Alberta insurance claim.
Why Calgary roofs are especially vulnerable to hail
Calgary sits in "Hail Alley" — the corridor stretching from southern Alberta into Saskatchewan that sees more large-hail events than almost anywhere else in Canada. The city averages several significant hailstorms per year, and a single storm can damage thousands of roofs in a matter of minutes. Understanding what hail actually does to a roof helps you make a better decision about repair vs replacement.

How to assess hail damage on your roof
Not all hail damage is visible from the ground. Here's what a proper assessment looks for:
Granule loss
Hail knocks the protective granules off asphalt shingles, exposing the underlying mat to UV and moisture. Look for bare spots, circular bruising, or a large volume of granules in your gutters after a storm.
Cracked or fractured shingles
Larger hailstones (1.5"+) can crack shingles outright. Cracks allow water infiltration and accelerate deterioration rapidly.
Dented metal components
Check gutters, downspouts, vents, and flashing for dents — these are the easiest indicators of hail size and impact force, and insurers use them as evidence.
Soft spots on the decking
In severe cases, hail can damage the decking beneath the shingles. A roofer walking the roof will feel soft spots that indicate structural damage below.
Repair vs replacement — how to decide
Repair may be sufficient when:
- Damage is isolated to one slope or section
- Hailstones were small (under 1")
- Shingles are relatively new (under 10 years)
- No cracking or fracturing — only minor granule loss
- Fewer than 10–15% of shingles are affected
Replacement is likely needed when:
- Damage is widespread across multiple slopes
- Hailstones were large (1.5"+ — golf ball size)
- Shingles are already 15+ years old
- Cracking, fracturing, or exposed mat is visible
- Insurer's adjuster recommends replacement
Navigating an Alberta insurance claim for hail damage
1. Document the damage yourself first
Take photos and video of your roof, gutters, and any dented metal before anyone touches anything. Date-stamp everything.
2. File your claim promptly
Alberta insurers typically require claims within one year of the storm date. Don't wait — delays can complicate your claim.
3. Get your own independent assessment
Hire a reputable Calgary roofer to inspect and document the damage before the insurance adjuster visits. Their report gives you an independent baseline.
4. Be present for the adjuster's inspection
Walk the roof with the adjuster and point out all damage. Ask for a copy of their report.
5. Review the settlement offer carefully
If the offer seems low, you can dispute it. A public adjuster or your roofer's documentation can support a higher settlement.
6. Choose your contractor independently
You are not required to use a contractor recommended by your insurer. Get multiple quotes from reputable Calgary roofers.
Post-storm scams to watch for in Calgary
- Storm chasers knocking door-to-door immediately after a hailstorm — often out-of-province contractors with no local accountability
- Contractors asking you to sign an Assignment of Benefits before any assessment
- "Free roof" offers that involve inflating the insurance claim — this is insurance fraud
- Pressure to sign a contract before your insurer has assessed the damage
- Requests for large deposits before work begins or materials are ordered
