How Chinooks Affect Roofing Materials

Temperature Changes

The rapid and sometimes drastic warming of the air during a chinook can cause roofing materials to expand and contract, weakening them over time. This can lead to warping, cracks and leaks.

Wind Damage

As Calgarians we all know how powerful the wind can get as it rolls off the mountains. And in extreme cases it can lift and tear shingles off your roof, exposing it to further damage.

Water Damage

In addition to the risk of leaks, Chinooks can quickly melt large amounts of snow and ice which can lead to water pooling, which can seep into the underlayer of your roof.

And since we all know this warm weather won’t stick around, the water will quickly re-freeze which could lead to ice build up on your roof, ruining the integrity of your roof and even your gutters.

Common Signs Of Damage After A Chinook

Once the weather has settled down, bundle up and keep an eye out for these common issues:

  • Missing or damaged shingles
  • Leaks or water stains inside
  • Cracked flashing and soffit around things like vents and skylights

If you notice one or many of these signs, give us a call right away to prevent further damage!

Preventative Maintenance

The best way to prevent chinook related damage is making sure your roof is in top shape, prior too! Conduct seasonal visual inspections, keep debris off your roof and out of your gutters, and of course call our team the minute you see any damage. Small issues will only get bigger once chinook season hits.

While chinooks bring a welcome warmth to winter, their impact on your roof can be severe. Understanding the risks, recognizing damage, and implementing preventative measures are crucial to protecting your home.
