Both halves of a healthy attic - airflow and insulation
Core Armour Exteriors Inc. installs, upgrades, and repairs attic ventilation and attic insulation for homes across Calgary and the surrounding communities. A healthy attic is a balanced system: intake vents draw fresh air in at the soffit, exhaust vents release hot moist air at the ridge, and an insulated, air-sealed attic floor keeps that airflow from stealing heat out of your living space.
We build and correct both halves of that system - the ventilation and the insulation - so your roof lasts longer, your energy bills drop, and winter ice damming stops at the source.
- Balanced intake & exhaust
- Ice-dam prevention
- Attic insulation to spec
- Lower energy bills

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 insulation
Topping up or replacing blown-in insulation to modern R-value targets for the Calgary climate.
Insulation removal
Clearing out contaminated, wet, or rodent-damaged insulation before a fresh install.
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.
Why attic insulation pays for itself
Heat rises, and in most Calgary homes the attic is where it escapes. Upgrading attic insulation is one of the highest-return improvements a homeowner can make: it lowers heating bills every winter, evens out cold spots and drafts, and reduces the temperature swings that age your roof from below.
We install blown-in insulation to a consistent, gap-free depth so you get full coverage across the entire attic floor. If your insulation is matted, water-stained, or crawling with signs of pests, we remove the old material first, correct the ventilation and air leaks underneath, and then blow in a clean, even layer that performs the way it should.
