Like most homeowners, you probably don’t think much about the attic. However, an attic’s ventilation system is an integral part of your roof and your home. It helps to cool your house during summer and prevent moisture damage during winter. Read on to learn more about attic ventilation.
Attic Ventilation Basics
Your attic ventilation system promotes good circulation beneath the roof. It pulls fresh air into the attic and lets the heat escape through the vents. Attic ventilation helps keep your attic cool in the warmer months and prevents moisture issues and mold.
Air moves through your attic in two ways: intake vents and exhaust vents. Generally, intake vents allow fresh air to enter your attic, while exhaust vents remove stale air from the house.
Intake Vents
Intake vents are typically located on the soffits. These vents function by drawing cooler air near the bottom of the attic. They can be installed as one continuous *soffit vent running along the length of the eave or as individual vents.
While soffit vents are usually adequate, their biggest concern is positioning. When insulating the attic, homeowners may accidentally block these vents. Once the vents are blocked, they no longer serve a purpose.
Blocked vents prevent fresh air from flowing freely into the attic.
You can also opt for gable vents installed on the side of your home. These vents are useful because they can act as both intake and exhaust vents depending on the direction of the wind.
Exhaust Vents
Ridge vents are the most common type of exhaust vents. They are usually installed along the ridge of your roof and release hot air from your attic. Ridge vents don’t disrupt the roofline; they are integrated into the roof.
Static vents with covers prevent precipitation from entering your home. There are many shapes and colors to choose from, meaning you can pick the ones that complement your roof’s shingles and design.
How to Inspect Your Attic Ventilation
Good attic ventilation is essential. If you’re curious about your attic ventilation, here are a few things to look for.
- Excessive condensation on the walls and windows indicates your attic is not well ventilated.
- Ice on the eaves is another sign of poor ventilation.
- Wet spots on the ceiling below your attic may indicate poor ventilation and moist air entering the attic.
Reasonable electricity bills, indoor air quality, and your roof’s longevity heavily depend on adequate roof ventilation. If you haven’t paid attention to your roof’s vents, make sure they’re functioning correctly.
Adequate attic ventilation helps keep your attic cool and moisture-free and prevents roof damage. If you’re unsure about the condition of your attic vents and want to promote good airflow, hire a professional to assess the ventilation in your attic.
