Ventilation and moisture diagnosis for Calgary attics
Core Armour Exteriors Inc. assesses attic ventilation and roof conditions for homes across Calgary and the surrounding communities. A healthy attic needs balanced intake and exhaust airflow, and moisture problems such as attic rain and ice dams need to be traced to their underlying cause.
We explain what we find and outline the ventilation or roof work that fits the condition, without presenting full attic insulation as an offered service.
- Balanced intake & exhaust
- Attic-rain diagnosis
- Ice-dam diagnosis
- Ventilation corrections

The full system
What our attic services cover
Every attic we work on gets assessed as a complete system before we touch it. Depending on what your home needs, the work includes:
Intake ventilation
Clearing and installing soffit vents so cold, dry Calgary air can enter the attic freely.
Exhaust ventilation
Installing ridge vents, box vents, or powered exhaust vents to release rising heat and humidity.
Baffles & chutes
Keeping insulation from choking the airflow path at the eaves.
Attic-rain diagnosis
Tracing frost, moisture, and condensation patterns to understand what is happening in the roof space.
Ice-dam diagnosis
Assessing winter ice buildup and the ventilation or roof conditions connected to it.
Air sealing
Closing the gaps around light fixtures, plumbing stacks, and the attic hatch that leak warm air upward.
Why attic ventilation matters in Calgary
Calgary's freeze-thaw winters are hard on roofs, and most of that damage starts in the attic. When warm household air leaks into a poorly vented, under-insulated attic, it melts the snow on the roof deck. That meltwater runs down to the cold eaves, refreezes, and builds an ice dam that backs water up under your shingles.
Balanced ventilation keeps the attic cold and dry, so the snow stays frozen and the water stays outside where it belongs. Good airflow protects your home in summer, too - an attic without proper exhaust can climb well past 60°C, driving heat into your upper floors and forcing your air conditioning to work overtime.
Finding the cause of attic moisture
Frost, condensation, and ice dams can point to a ventilation or moisture problem in the roof space. We assess the airflow and the visible conditions so the next step is based on what is actually happening in the attic.
Insulation may be part of the diagnostic context, but full attic-insulation jobs and insulation removal are outside Core Armour's confirmed service scope.
