Question: 1 / 400

What function does attic ventilation serve?

Enhances aesthetic appeal of the roof

Reduces moisture build-up in the attic

Attic ventilation plays a critical role in maintaining a healthy environment within the attic space, and one of its primary functions is to reduce moisture build-up. When there is inadequate ventilation, warm air can become trapped in the attic, leading to condensation on surfaces. This moisture can promote the growth of mold and mildew, which can cause significant damage to the structural components of the home and lead to health issues for the occupants.

Proper attic ventilation helps to ensure that air can flow in and out, which helps regulate temperature and moisture levels. By allowing humid air to escape and cool, dry air to enter, the risk of condensation is diminished. This not only protects the integrity of the roof and attic insulation but also contributes to the overall longevity of the home’s structure.
