The Truth Behind Popular Attic Ventilation Myths

Good airflow in your attic helps keep hot, humid air out of your living space. Keeping your attic properly ventilated also helps you avoid roofing problems and the need for costly repairs. If your attic lacks ventilation, its temperature will rise, which can speed up the deterioration of roofing shingles. 

Attic Ventilation Myths

Read on to discover the truth behind some of the most popular myths about attic ventilation. 

Only Homes in Warmer Climates Need Roof Vents

Yes, attic ventilation contributes to your home’s overall energy efficiency and helps keep you comfortable during the warmer months. Roof vents help prevent your HVAC system from working too hard in summer, reducing your energy costs. However, it’s a common misconception that roof vents are only for warmer climates. They are beneficial in colder climates too since they reduce the risk of moisture-related issues. 

The More Ventilation, the Better

The lack of ventilation can result in poor energy efficiency in summer and moisture issues in winter. But did you know that insufficient ventilation is just as problematic as excessive ventilation? One of the most common areas where leaks occur is roof vents. Having too many vents significantly increases the likelihood of roof leaks. At Sterling Exteriors, our roofing experts can determine the right amount of ventilation for your attic. We’re here to help with your home’s exterior and outdoor living needs. 

Roof Vents Get Rid of Warm Air in Winter

Because warm air naturally rises, many homeowners believe that attic ventilation allows heated air to escape in winter. However, energy loss doesn’t usually occur due to roof vents but insufficient insulation. If you don’t have enough insulation, warm, humid air will enter your attic, compromising the wooden components of the space. Your HVAC system won’t be heating your attic unless your roof has insulation on the decking and is made without ventilation.
