Having a well-ventilated attic is essential for many reasons. However, some older homes don’t have this kind of ventilation. What happens if an attic is not vented? Knowing more about the types of problems that a lack of ventilation might cause can help homeowners understand why they should make sure they have a properly ventilated attic.

Importance of Attic Ventilation


What makes attic ventilation so crucial for your home? Ventilation helps prevent moisture and heat from building up in your attic. Cool outdoor air is pulled through certain vents when your attic has proper ventilation, while warmer indoor air flows out of other vents. Vents help your attic maintain a steady temperature that isn’t too hot.

Attic ventilation also helps keep this part of your home from becoming too moist, which can lead to mold growth, rot, and other issues. These ventilation systems also help improve your home’s energy efficiency since they prevent your interior from becoming too hot in the summer. With proper ventilation, your roofing system can also last longer and have a lower chance of developing problems.

Areas for Attic Vents


Attic vents include intake vents and exhaust vents. Intake vents are installed in low areas of your attic to bring in cool air from outside. Exhaust vents are installed in higher areas of your attic to eliminate heat and moisture. Different types of attic vents typically refer to where they’re placed. Ridge vents go on the edges of your roof, while soffit vents are installed on the undersides of your roof. Gable vents are installed on roof gables.

Problems with Inadequate Attic Ventilation


What can happen if your attic isn’t adequately ventilated? When it’s hot out, exposure to the sun’s heat can warm up your attic and lead to roof damage. This heat can cause the roof sheathing to become warped, making it harder for your roof to protect your home from the elements. Exposure to the sun’s heat can also cause roof shingles to warp or become brittle, which can shorten their lifespan.

Attic ventilation helps prevent heat from building up inside this part of your home. This helps reduce the risk of your roof shingles or sheathing becoming damaged or warped. With proper ventilation, the heat from your attic won’t seep into your home interior. This helps it stay cooler in summer, so you don’t have to rely on your air conditioning system as much.

A lack of attic ventilation can cause moisture problems in your home. Attic ventilation helps prevent moisture from accumulating in this part of your home. Without vents, moisture builds up in your attic, leading to water damage, roof deterioration, insulation damage, and other problems. If your attic tends to stay warm, mildew and mold can grow when moisture levels are high.
