Why Is Attic Ventilation Important in Winter?

Why Is Attic Ventilation Important in Winter?

Some people assume that roof vents are simply for cooling a hot attic in the summer. But roof vents are as important in the colder months.

Attic Ventilation Protects Against Moisture Damage

Since windows and doors tend to be closed and air in living spaces is heated during freezing temperatures, the moisture vapors from cooking and showering are carried into the attic. Without proper attic ventilation, moisture can accumulate on attic surfaces and cause mold, mildew, rot and ice dams to develop.

Different Types of Attic Ventilation

Attic ventilation is categorized into intake and exhaust vents. Intake vents draw cool, fresh air from the outside into the attic while exhaust vents allow hot, stale air to flow out of the attic.

Intake Vents

  • Soffit vents. Also called an under eave vent, a soffit vent is continuous and perforated. It is installed under the home’s eave and can easily be covered by insulation.

  • Rafter vents. A rafter/baffle vent works with an under-eave vent to provide a clear path for the air. It is installed along the rafters where the ceiling and floor meet.

  • Gable vents. A gable vent is installed at the highest point of the roof. It can serve both intake and exhaust ventilation functions.

Exhaust Vents

  • Ridge vents. This is a vent that runs along the ridge of the roof. As it is often disguised by shingles, it integrates well with the roof line.

  • Turbine vents. A turbine vent contains a small fan that spins with the breeze. It is also installed on or close to the ridge.
