Damage We See

Calgary's wind, hail, and snow load find every weakness

Calgary throws everything at your roof, sometimes all in the same week. Chinook winds gust past 100 km/h. Hail bruises shingles. Freeze-thaw cycles crack sealant and force meltwater under flashing.

Kristian has repaired Calgary roofs through every major hail event since 2010, including the June 2020 storm that caused $1.2+ billion in insured damage across NE Calgary. That hands-on experience shapes how we diagnose every leak.

What We Repair

Calgary roof problems we fix every week

If you see your problem on this list, you're in the right place. If not, we'll figure it out during your free inspection.

Wind-Lifted & Missing Shingles

Chinook winds regularly gust past 100 km/h, peeling back shingles already weakened by UV or improper nailing.

Hail Impact Damage

Soft bruising accelerates granule loss and shortens roof life by 5–10 years if left unaddressed.

Ice Damming Along Eaves

Freeze-thaw cycling during January chinooks forces meltwater under shingle edges and into the attic.

Flashing Failures

Sealant and metal flashing around vents and chimneys crack under -30°C to +15°C swings in a single day.

Rotted Roof Decking

Spongy or sagging spots usually signal prolonged moisture from an undetected leak. We cut out and replace.

Emergency Tarping

Active leak? We prioritize emergency calls, temporary tarp first, permanent fix scheduled right after.

Emergency Leak?

What to do before we arrive

  1. 1 Contain the water. Place a bucket under the drip. If the ceiling bulges, carefully puncture the lowest point with a screwdriver to release pooled water before drywall collapses.
  2. 2 Move valuables and electronics away from the affected area.
  3. 3 Call Top Star at (403) 603-0650. We prioritize active leaks and respond as fast as Calgary weather allows.
  4. 4 Take photos of the water entry point and visible damage, these help us and your insurance adjuster later.
"After 15 years on Calgary roofs, I can tell you 80% of emergency leaks trace back to failed flashing or wind-lifted shingles, not a full roof failure. We'll do a temporary tarp or patch to stop the water, then come back for the permanent fix."
Kristian Lamthi, Owner

Repair vs. Replacement

The honest conversation

Not every problem requires a $15,000–$25,000 replacement. And not every repair makes financial sense if the roof has 2 years left.

A repair makes sense when:

  • • Damage covers less than 25–30% of the roof area
  • • Shingles have 8+ years of expected life remaining
  • • Decking shows no rot or moisture damage
  • • Problem traces to a specific failure point

A replacement makes more sense when:

  • • Roof is 20+ years old with widespread granule loss
  • • Multiple leak points across different sections
  • • Decking feels spongy in more than one area
  • • You're on a second or third insurance claim on the same roof

FAQs

Calgary roof repair, common questions

How much does roof repair cost in Calgary?

Most Calgary roof repairs range from $300 to $3,000 depending on scope. A single flashing repair or vent boot might run $300–$600, while a wind-damaged shingle section typically runs $1,200–$2,500. Top Star provides a free inspection and itemized written quote before any work begins.

Does home insurance cover roof repair in Calgary?

Most Alberta home insurance policies cover roof damage from sudden events, hailstorms, wind, falling debris. They typically don't cover gradual wear, neglect, or aging. Top Star has supported hundreds of documented insurance claims.

How quickly can you respond to an emergency leak?

Top Star prioritizes active leaks. Call (403) 603-0650, we'll walk you through containment over the phone and schedule a same-day or next-day visit depending on weather and timing.

How do I know if my roof needs repair or full replacement?

A repair makes sense when damage covers less than 25–30% of the roof, shingles have 8+ years of life left, and the decking is solid. If your roof is 20+ years old, has widespread granule loss, or multiple active leak points, a replacement delivers better long-term value.

What are Class 4 impact-resistant shingles, and should I get them?

Class 4 shingles pass the UL 2218 impact test, resisting cracking when struck by hail. Given Calgary's position in Canada's hail alley, they provide measurable protection, and many Alberta insurers offer 10–30% premium discounts for Class 4 roofs.

What is attic rain and why does it happen in Calgary?

Attic rain is condensation caused by Calgary's chinook events. Warm, moist indoor air rises into the attic and condenses on the cold roof deck. When a chinook warms the exterior, that frost melts and drips down, mimicking a roof leak. See our Attic Rain page for the full fix.
