In addition to ensuring the longevity of your roof, it guarantees the comfort of the occupants. Unfortunately, it is often neglected. However, poor ventilation can lead to many problems, including poor quality of the air you breathe in your home. Discover its importance in this article.

Attic ventilation

The attic is the space between the ceiling and the roof where fresh air should circulate. An evacuation of hot and humid air is also essential. The ventilation system must then be balanced, the quantities of air entering and leaving must be equivalent. This ensures optimal air circulation, reducing the risk of humidity forming in the attic.

Here’s why attic ventilation is so important:

  • Preventing excessive heat buildup

In the summer, heat builds up, and a lack of attic ventilation will make this worse. The warm air in the attic increases the temperature of the roof. This overheats the underlying materials. Shingles, for example, deteriorate more quickly.

  • Reducing humidity

Inadequate ventilation causes condensation to accumulate. In the winter, a lot of warm, humid air comes from inside the house. This air meets the cold surface of the attic ceiling. This can cause a variety of problems: moisture condenses; mold sets in; insulation deteriorates; roofing materials rot.

  • Maximizing the life of your roof

Proper ventilation maintains adequate temperatures and more stable humidity levels. These conditions help preserve the integrity of your roof over the long term. Indeed, excessive heat and humidity damage materials quickly.

  • Improving energy efficiency

Poor ventilation affects the thermal efficiency of the home. Hot air stagnates in the attic, heating the house in the summer and increasing the demand for air conditioning. In the winter, the lack of ventilation causes heat loss. Your heating system will have to run longer. Proper ventilation regulates the interior temperature. This reduces energy costs.

How to optimize attic ventilation?

Regular maintenance of the ventilation openings is essential. Clean the grills and vents. No debris should block the airflow. Do this once a year, before winter sets in.

If you have airflow problems, add additional vents. Also have any clogged soffit grilles repaired. You can also install a mechanical, turbine or solar ventilation system.
