Ventilation involves circulating air to keep it fresh and to reduce moisture levels. About 90% of homes in the U.S. have high moisture levels. Understanding what form of attic ventilation you should have might be a roof-saver. There are a lot of falsehoods about attic ventilation. We debunk some of those myths now.
More Is Better
This isn’t necessarily true. You should want only the right amount of attic ventilation for your home. Less leads to moisture problems in winter and decreased energy efficiency in summer. Too much ventilation, though, can be also as bad, if not worse.
Roof vents create added roof penetrations where leaks can occur. You shouldn’t have more than what’s necessary. They can cause blowouts during high winds or allow sparks from a wildfire to enter your home and cause a fire. To know just how much ventilation is appropriate, you should consult your roofer.
Ventilation Is Important Only for Warmer Climates
Roof ventilation is not the only way to increase energy efficiency during the summer. Shingle color, sun exposure and insulation all contribute to total energy efficiency. Attic ventilation is more important to your home in colder climates. In warmer climates, you don’t necessarily need to worry much about condensation.

Vents Remove Warm Air in Winter
Many believe that ventilating an attic in winter releases the warm air you need. Poor insulation is actually the culprit. On a sunny winter day, your attic space can get hot from sun exposure. Worse yet, inadequate insulation allows moisture-laden air into your attic. When this air hits your roof, it will form condensation. It will then lead to further deterioration of your insulation or wood rot.
