Symptoms

Before you call a roofer, watch for these warning signs of attic rain; one of Calgary’s most misdiagnosed home issues:

Brown ceiling stains or drywall damage around light fixtures or the attic hatch.
Moist air or musty smells in upstairs rooms, especially near a bathroom fan.
Difficulty reducing condensation in the attic despite using fans or dehumidifiers.
Leaks that appear during a cold spell often follow freezing nights.
Humidity levels that feel high indoors, even with ventilation running.
Condensation on attic roof boards or visible attic frost after a cold snap.

What Causes
Calgary Attic Rain?

Attic rain typically begins with changes within your living space. In Calgary, we often see attic rain triggered after renovations or energy upgrades that unintentionally disrupt the balance of air flow, sealing, and insulation in the attic.
  • Poor or unbalanced ventilation allows humid air to build up in the attic.
  • Air leaks and gaps in the vapour barrier, or missing spray foam around penetrations, provide a path for warm air to enter.
  • New furnaces, siding, or pot lights create weak points that can lead to frost and eventual damage to the ceiling drywall.
  • High relative humidity inside your home, combined with cold days and sudden warmer weather, creates freeze-thaw cycles that trigger attic condensation, also known as attic rain.
  • Inadequate insulation in key attic spaces allows temperature rises and condensation to form, worsening the problem over time.

FAQ

How Do You Prevent Attic Rain?

Attic rain is prevented by sealing air leaks around attic hatches, pot lights, and bathroom fans, ensuring balanced ventilation with proper intake and exhaust. This helps manage indoor humidity during winter and improves insulation by applying spray foam to reinforce the vapour barrier.

Can Attic Rain Cause Mould?

Yes. When moisture from attic rain drips into insulation, wood, or ceiling drywall, it creates ideal conditions for mould. Mould growth can begin within 24 to 48 hours and, if left untreated, can spread quickly, affecting both the structure of the home and the air quality inside.

Why Does Attic Rain Occur in Winter? (How Does Weather Contribute?)

Attic rain takes place in winter when warm, humid air from inside the home rises into the attic and freezes on cold surfaces. When chilly days are followed by warmer weather, or during a chinook, that frost melts suddenly and drips, appearing like a roof leak. In Calgary, temperature swings from –20 °C to +10 °C in a matter of hours can trigger attic rain events overnight.

Does Insurance Cover Attic Rain?

In most cases, attic rain is not covered by standard homeowners’ insurance because it is considered a maintenance and ventilation issue. Some policies may provide partial coverage, but this depends on your provider. In Alberta, the New Home Warranty program does cover attic rain, but only within the first five years after a home is built.

Is Attic Rain Common in Calgary?

Yes. Attic rain is a common occurrence in Calgary due to the city’s unique climate. Freeze-thaw cycles and Chinook winds create rapid temperature changes that cause frost in the attic to melt quickly. Even newly built or renovated homes can experience attic rain if ventilation, sealing, and insulation are not properly balanced.

I highly recommend Attic Rain. The wealth of knowledge, professionalism and quality of work is phenomenal. The honesty and step by step explanations of how the work is to be done and was done is so appreciated as a homeowner. John was very informative and upfront after he inspected my attic. Sam and his crew were so respectful, polite, genuine and kind and he made a point to check and double check that there was no debris left and everything was clean once the job was completed. Sam took the time to communicate with me before, during and after the job and took pictures all throughout the process. I have never trusted a company and the work they performed as much as I do with Attic Rain.
