Preventing Attic Mold with Proper Attic Ventilation

There are many reasons why mold can develop inside the attic, including poor insulation, condensation, lack of proper attic ventilation and moisture seepage. Today, however, we are just going to focus on attic mold due to lack of proper attic ventilation. Many homeowners don’t realize that the attic isn’t just a random side effect of building construction, but a really underrated feature of a home – a feature that plays a huge role in your energy bill and the health of your family. Proper Attic Ventilation is essential for a healthy home!

Why Proper Attic Ventilation is Important

The attic is really an amazing part of the house. In some houses, it is often used as a storage space, but for most homes, the attic’s primary purpose is to create a buffer between the roof and the rest of your home. This helps keep the temperatures more stable inside the house; a process that can be highly effective when the attic floor and rafters are properly insulated.

However, because it is a type of buffer, the attic tends to undergo frequent temperature changes that can lead to condensation and excessive heat, both of which create optimal conditions for mold growth.

One way to significantly reduce the chances of attic mold is to ensure proper attic ventilation. This will create better airflow within the attic, and will efficiently remove moisture and excessive heat.

How to Properly Ventilate the Attic

The first step in proper attic ventilation is to ensure that the attic floor is properly insulated. This is vital because the airflow will otherwise make your HVAC system inefficient.

Once the insulation has been properly installed, the next step is to ensure that the soffit vents are installed correctly and are functioning properly. This requires several considerations.

  • Firstly, the soffit vents should all be exactly the same. This ensures a balanced air intake, and allows for stronger airflow through the attic, which in turn eliminates possible pockets of hot, static air.
  • Secondly, the soffit vents must be placed as far from the sides of the house as possible. This ensures that the air entering the attic is less likely to be affected by the temperature of the walls.
  • Thirdly, it’s important to ensure that there’s enough space for the air to pass into the attic, as this creates stronger airflow. Typically, this means leaving approximately 1-2 inches of space between the roof sheathing and the insulation.
  • Lastly, it’s also advisable to slightly pressurize the attic by adding more ventilation at the eaves, and less at the ridge. The pressurization of the attic will prevent the air from inside the house from passing into the attic.
