Attic Rain & Ice Damming Prevention & Repair
Attic rain, frost buildup, and ice damming are common problems in Edmonton and across Alberta, especially during long cold winters. These issues are typically caused by heat loss, air leakage, and poor attic ventilation — not just a lack of insulation. We specialize in identifying the root cause of attic rain and ice damming problems and providing long-term solutions that protect your home from moisture damage.
Understanding Attic Rain and Ice Damming in Alberta Homes
During cold weather, warm air from inside the home can escape into the attic. When this warm, moist air contacts cold roof surfaces, condensation can form and freeze.
As temperatures fluctuate, this frost can melt and drip back down onto insulation and ceilings — a problem commonly referred to as attic rain.
Ice damming is another symptom of attic heat loss. When heat escapes into the attic, snow on the roof melts unevenly and refreezes near the roof edge.
Over time, ice dams can force water under shingles, leading to roof leaks, ceiling stains, and long-term structural damage. Both attic rain and ice damming are signs that the attic system is not functioning properly.
Attic Rain Prevention and Repair
Attic rain is not a roofing issue — it is an attic system issue. Preventing attic rain requires controlling warm air movement, managing moisture levels, and ensuring proper ventilation.
In many cases, existing insulation has become wet, compressed, or contaminated and is no longer performing effectively.
Attic rain repair may involve selective insulation removal, air sealing to reduce heat loss, ventilation corrections, and insulation upgrades. Every attic is different, which is why we focus on inspection and diagnosis before recommending repairs.
Ice Damming Prevention and Repair
Ice damming occurs when heat escapes into the attic and warms the roof surface unevenly. This causes snow to melt and refreeze at the eaves, creating ice buildup that traps water.
Over time, this can lead to roof leaks, damaged shingles, and interior water damage.
Effective ice dam prevention focuses on reducing attic heat loss and improving ventilation rather than temporary solutions like heat cables.
By addressing insulation levels, air sealing, and airflow balance, we help reduce the conditions that cause ice damming in the first place.
Attic Ventilation and Airflow Solutions
Proper attic ventilation is critical for managing moisture and temperature. Poorly balanced or inadequate ventilation can trap warm, moist air in the attic.
This increases the risk of condensation, frost buildup, and ice damming during cold weather.
We assess existing roof vents, whirlybirds, and intake ventilation to determine whether airflow is properly balanced.
When necessary, we recommend ventilation improvements designed to meet Alberta building requirements and support long-term attic performance.

FAQ
What causes attic rain?
Attic rain is caused by warm, moist air escaping from the living space into a cold attic. When this warm air contacts cold roof surfaces, condensation forms and freezes. As temperatures change, the frost melts and can drip back down onto insulation and ceilings, creating moisture damage.
Do ice dams mean I need new insulation?
Not always. Ice dams typically indicate heat loss or ventilation problems in the attic. In some cases, insulation upgrades are needed, but air sealing and ventilation corrections may also be required to properly resolve the issue.
When is insulation removal necessary?
Insulation removal may be necessary when insulation has become wet, compressed, mold-affected, or contaminated. Damaged insulation cannot properly control heat loss and moisture, and replacing it is often part of a long-term attic solution.
Is attic rain and ice damming common in Edmonton homes?
Yes. Attic rain and ice damming are common in Edmonton and throughout Alberta due to cold winters and frequent temperature fluctuations. Homes with poor ventilation or air leakage are especially susceptible to these issues.
