Attic ventilation not only helps to keep cooling costs low, but also extends your roof’s lifespan and makes your living space comfortable. Poor attic ventilation translates to increased electricity bills, mold and moisture damage, and poor indoor air quality.
Although most homeowners appreciate the benefits of proper attic ventilation, there are still a lot of misconceptions about attic ventilation. At Pro Atlanta Roofing , we’re going to debunk the common myths about attic ventilation once and for all.
Contrary to the popular belief, attic ventilation is important in all climates for better energy efficiency and preventing moisture damage. Even in colder climates, homes need proper attic ventilation and sufficient insulation to prevent condensation and moisture damage.
It’s true that heat rises into the attic and then escapes through the vents. However, this occurs as a result of poor insulation and not because the vents are removing warm air. A roof with poor insulation will allow warm, moist air to creep into the attic, resulting in wood rot and other problems. So, if your vents are releasing warm air, the real culprit is insufficient insulation—not your attic ventilation.

Too many people believe that vents can create a drag on your heating system, especially when heat escapes through the vents. As we’ve already highlighted, this problem is usually caused by insufficient insulation and not attic ventilation.
More ventilation in your attic doesn’t always mean better. Too much ventilation can increase your risk of leaks and roof damage in the event of a hurricane. As a rule of thumb, you should have one square foot of ventilation per 300 square feet of ceiling space. However, too little ventilation can lead to moisture damage.
Another misconception is that attic ventilation is only effective for warm climates, where it can provide energy efficiency. The truth is attic ventilation comes in handy during the cold season to prevent moisture damage.
There are different types of attic ventilation systems, with some being more effective than others depending on your location and type of roof. For example, gable vents offer passive ventilation while soffit vents are designed for intake, thereby there's a risk of air being sucked back into your house. Ridge vents ensure air circulates continuously, so they are much more effective than soffit vents and gable vents. In addition, it's important to install baffles on your vents to ensure proper circulation of air in your attic. You may have to consult with roofing contractors in Decatur when you're looking to install baffles.
