The Hidden Threat Above: Why Calgary’s winters Demand an Attic Inspection

In Calgary, winter is more than just a season; it’s a structural test for your home. While you worry about your furnace, the real danger is often lurking where you can’t see it: the attic.

As licensed inspectors, we at NexLevel Home Inspections know that the first major freeze often exposes deficiencies that were invisible all summer. These issues—primarily related to moisture, insulation, and ventilation—lead directly to the most expensive winter damage.

Ignoring your attic during the deep freeze is not saving money; it’s placing a very costly gamble.

The Winter Trifecta of Attic Damage

Calgary’s climate—with its deep cold snaps followed by Chinook warm-ups—creates a perfect storm for attic problems. These three issues are often preventable with a simple inspection.

1. The Ice Dam Nightmare

Ice damming is the classic Calgary winter crisis. It occurs when:

• Heat Escapes: Warm air from your living space leaks into the attic (due to poor sealing or insufficient insulation).
• Snow Melts: This heat melts snow on the upper roof, which then runs down to the cold eaves and freezes, forming an ice dam.
• Water Backs Up: This dam traps water, forcing it under the shingles and into your walls and ceilings, leading to catastrophic leaks.

The Cost of Complacency: Ice dam removal alone costs between $450 and $1,200. But the resulting interior damage, including drywall, paint, and potential structural rot, can easily push total repair costs into the $3,000 to $5,000+ range.

2. The Hidden Mold Factory (Attic Rain)

Condensation and moisture are the biggest enemies of your attic space during the winter. When warm, humid air from your home hits the freezing cold underside of your roof deck, it causes massive frost buildup.

When the temperature rises—like during a Chinook—that frost melts into a deluge known as Attic Rain.

• The Damage: This excess moisture can saturate your insulation (killing its R-value), rot the wood decking, and, most alarmingly, trigger mold growth inside your roof structure.
• The Cost of Mold: Attic mold remediation in Calgary typically costs between $1,000 and $4,000, and that doesn’t include the cost to replace the compromised insulation and decking.

3. Wasted Energy and Skyrocketing Bills

If your insulation is compressed, wet, or simply inadequate for Alberta’s deep winter, you are literally losing money through your roof.

• What We Check: We measure your insulation’s R-value, check for thermal bridging (gaps where heat leaks out), and verify that soffit vents are not blocked by snow or insulation.
• The Cost of Inefficiency: Calgary homeowners spend an average of $4,165 on insulation projects. Catching a small air leak now can prevent the need for a full, expensive insulation blowout and replacement later.
