Even in the Southeast U.S., Attic Ventilation Is Imperative Throughout the Year

Published on: December 30, 2013

Most people realize the importance of having a well-ventilated home throughout the year, but not everyone thinks of their attic as part of this equation. The reality is that attic ventilation is almost as important as it is elsewhere in your home. Ignoring this area can result in several negative consequences, versus the many benefits that come with proper ventilation. Find out why having a good ventilation system in your attic is so vital for protecting major parts of your house, improving your indoor comfort levels, and saving you energy dollars over time.

Why is Attic Ventilation So Important?

During the fall and winter, a well-ventilated attic:

  • Preserves the insulation. Without proper ventilation, moisture can build up in the insulation, degrading its heat resistance capabilities. Attic ventilation also helps prevent moisture from accumulating on the ceiling, which, left unchecked, can ruin the ceiling, lead to mildew and cause the paint to peel.
  • Protects your roof. If there’s not a good ventilation system in your attic, moisture buildup can wreak havoc on your roof, making the wood rot and causing the shingles to buckle. Additionally, proper ventilation helps any ice on the roof melt evenly; this prevents it from collecting and refreezing on the roof’s edge, which can damage the gutters. This isn’t a big problem in the Southeast, but it can happen in some parts of the region.

In the spring and summer, attic ventilation:

  • Extends the life of your air conditioner. As you know, summers get hot in the Southeast. Your attic can reach temperatures up to 145 degrees F if it’s not equipped with proper ventilation. The extreme heat then enters your home through the attic floor, making your air conditioner work even harder. Built-up attic heat and humidity can also damage your shingles.
  • Reduced strain on your air conditioner. Proper attic ventilation – with a mix of an attic fan and the right type and amount of vents – can lower the temperature between 30 and 50 degrees so your cooling system won’t have to fight so hard to conditioner the air in your home, reducing the need for costly repair jobs and lowering your energy use (saving you up to 25 percent on monthly bills).
