Calgary is known for many things — sunshine, wide-open skies, and of course, weather that can turn on a dime. Anyone who has lived here through a winter knows how quickly temperatures can swing from deep-freeze cold to springlike warmth and back again. While these dramatic weather patterns are a part of Calgary’s charm, they also create one of the most common winter roofing problems: ice dams.

Ice dams can cause serious damage to a roof, shingles, gutters, and even the interior of your home if they’re not dealt with quickly. Understanding how they form and why Calgary is particularly prone to them can help homeowners stay ahead of the problem. And when damage does occur, Advanced Level Roofing is here with fast, reliable winter roof repair services to protect your home.

Why Calgary’s Weather Creates the Perfect Conditions for Ice Dams

Ice dams form when heat escapes from your home and warms the roof, causing snow to melt. When that melted snow runs down toward the colder edges of the roof — usually the eaves — it re-freezes. Over time, this frozen ridge creates a dam that traps water behind it. That pooled water can seep under shingles, get into the roof deck, and lead to leaks, wood rot, and even mould inside your home.

Calgary’s temperature swings make this process happen quickly and frequently. One day it might be well below freezing, and the next a Chinook rolls in, melting snow rapidly. After the warm air passes, temperatures drop again, causing the meltwater to freeze in place. This constant cycle of thawing and freezing is exactly what makes Calgary homeowners especially vulnerable to ice dams.

Even homes with newer roofs can experience ice dams simply because the weather changes so drastically from one week to the next. Without proper attention, this repeated freeze–thaw cycle can start to take a toll on your roofing materials.

Signs You May Have an Ice Dam Forming

Ice dams often start small, and many homeowners don’t notice a problem until water begins leaking into the house. But there are early warning signs you can watch for:

Thick ridges of ice building along the gutters or roof edge
Icicles forming in clusters
Water stains appearing on ceilings or walls
A noticeable temperature difference in your attic
Shingles that appear warped or loose after a freeze–thaw cycle

If you spot these signs, it’s important to act quickly. The longer an ice dam sits on your roof, the more potential damage it can cause.
