If you live in Calgary, you’ve likely heard the term “attic rain.” It may sound harmless, but attic rain can cause serious damage to your home—especially in the form of ceiling cracks and moisture problems. Understanding how attic rain develops and why it demands prompt action can help you protect your property from costly repairs.
At Crack and Attic Doctor, we’ve helped countless Calgary-area homeowners fix the hidden damage caused by attic rain, including insulation problems, ceiling cracks, and mold growth.
What is Attic Rain?
Attic rain happens when warm, moist indoor air rises into a cold attic space—especially during winter. If the attic isn’t properly insulated or ventilated, that warm air condenses on the cold roof sheathing and turns into frost. When temperatures rise, the frost melts and “rains” down into the attic insulation and ceiling below.
How Attic Rain Leads to Ceiling Cracks
Here’s how this hidden process can damage your ceilings:
1. Moisture Damage
Melted frost soaks insulation and the drywall underneath. As moisture builds up over time, it weakens the ceiling structure.
2. Expansion and Contraction
Wet materials expand. Then when things dry, they shrink—causing stress cracks in the ceiling. This cycle can repeat every winter in Calgary, making cracks worse.
3. Sagging or Buckling
Over time, continuous attic rain can cause your ceiling to sag, buckle, or even collapse in extreme cases.
4. Mold Growth
The combination of moisture and warmth also creates the perfect environment for mold, which adds another layer of damage and health risk.
