Many people think of an attic as a space that provides storage and roof support. However, this area also plays an important role in ventilation. Without optimal airflow through the attic, you can run into numerous problems, including structural damage, mold growth, and inefficient air conditioning. To keep your home strong, comfortable, and safe, here’s what you should know about attic ventilation.

How Does Attic Ventilation Work?

Functional attic ventilation allows outside air to flow in and out of the attic. This flow removes excess heat and moisture so that your home can maintain a balanced temperature.

These systems are primarily comprised of vents in the main roof surface, as well as soffits, gables, eaves, and ridges. Baffles may be used to direct the airflow, while insulation is used to prevent it from moving through to lower parts of the home. Fans or ventilators may also be used to circulate air.  

Why Is Attic Ventilation Important?

Improves Heating & Cooling Efficiency

Attic vents and insulation shield hot and cool air from passing through to the lower levels of your home. As a result, your heating and air conditioning systems won’t have to work as hard to maintain a balanced indoor climate.

Prevents Ice Dams

If indoor heat has nowhere to escape during the winter, certain areas of the roof may get too warm. This heat will melt snow on the outside of the roof until it drips down to the eaves and refreezes. Over time, this buildup of ice will create a dam that puts the roof structure at risk of water damage.

Strategically placed vents in the attic make it so that heat can escape without warming up roof surfaces.

Deters Mold Growth

The humidity of hot summer air can dramatically increase the moisture levels inside the attic. With the right amount of moisture, mold spores can start growing. Left uncontrolled, mold growth can damage the interior structure and expose your family to potential health risks.

Proper airflow ensures that moisture is moved out of the attic along with the air to keep humidity to a minimum.
