Calgary, with damage reported in the northwest and northeast
- INSURED LOSS
- $164 MILLION
- HAIL
- GOLF BALL, AS DESCRIBED BY CBC
What happened on July 13, 2025
On the evening of Sunday, July 13, 2025, a fast-moving thunderstorm crossed Calgary with hail CBC described as golf-ball sized and gusts Environment Canada measured at up to 93 km/h in the northeast around 8 p.m. IBC puts the insured damage at $164 million (September 2025), almost double the first estimate, and more than half of all claims were for vehicles.
CBC named Thorncliffe, North Haven and Mount Pleasant in the northwest and Mayland Heights in the northeast among the communities hit, and Global News reported damage in Highwood and Albert Park/Radisson Heights. The Calgary Fire Department took 70 weather-related calls in about 95 minutes from 8 p.m., mostly power lines brought down by trees.
The first CatIQ estimate in August 2025 was close to $92 million, with vehicles making up 65% of claims. By September it had risen 78% to $164 million, with commercial losses increasing significantly. Roof damage from a storm this size tends to be patchy, street by street, which is where a close look is worth more than a guess from the ground.

What it means for your roof today
Hail damage can sit on a roof for years without a leak. A bruise can look like nothing from the street, and the longer it waits the harder it is to tell from ordinary wear. If you were in the area on July 13, 2025 and nobody has looked at your roof since, have it checked and keep the date with your notes.
In Alberta, the statutory conditions in a home policy require prompt written notice of a loss, and a court action over a property claim generally has to start within 2 years of when you knew or ought to have known about the damage. Your policy may set other time limits, such as a deadline to claim depreciation. That's general information, not legal advice: your policy wording governs, and your insurer or a lawyer can tell you where you stand.
Check your hail or wind deductible on your declarations page before you file. Filing is your decision. We inspect, photograph every slope and write the damage up against the storm date; you and your insurer handle the claim.
Signs of hail damage
The Insurance Institute for Business & Home Safety (IBHS) lists these as the signs of hail on an asphalt shingle roof, and the metal on the house usually backs them up:
- A random pattern of marks across a slope, not a line or one cluster.
- Bruises: soft spots you can feel when pressing on the shingle, where the mat under the granules has fractured.
- Cracked or broken shingles, especially along the ridge caps.
- Dents on the metal: the top of the eavestrough, vent caps, fence caps and the air conditioner, on the side the storm came from.
- Chips, cracks or holes in siding and window screens, which often show before anything on the roof does.
Look from the ground, not from a ladder. What it looks like in photos is on our hail damage guide.
STRAIGHT ANSWERS.
Is it too late to claim damage from the July 13, 2025 storm?
It depends on your policy and on when you found the damage. Alberta's statutory conditions require prompt written notice of a loss, and a court action over a property claim generally has to start within 2 years of when you knew or ought to have known about the damage. If you've only just found damage from this storm, report it now and ask your insurer what it needs. This is general information, not legal advice.
How do I show the damage came from this storm and not from age?
Hail leaves a recognisable pattern: random impacts, granule loss at the strike points and bruising you can feel, plus dents on the soft metals, which reads differently from even weathering. A report that photographs that pattern slope by slope, with scale references, and reasons from it to a dated storm is what ties damage to a date of loss. An assertion without that reasoning is not documentation.
My roof was replaced after this storm. Should I still get it looked at?
It can be worth it. Vents, flashing, skylights, eavestrough and siding take hail on their own, and they can be left out of a roof-only scope. If anything on the house wasn't replaced, it's worth a look.
Why did the estimate for the July 13, 2025 storm change?
First reported at close to $92 million in August 2025. The latest figure is $164 million, published September 2025. Insured-loss estimates are revised as claims are counted and closed, so an early number is rarely the final one.
