Importance of Attic Ventilation for your HomeBy Stacy Mellete
Many people overlook the importance of attic ventilation. Proper ventilation not only prolongs the lifespan of your roof but also provides comfort for your family. Additionally, it can also help you save money on energy bills and avoid costly repairs.
How Attic Ventilation Works
Attic ventilation utilizes two types of vents to regulate proper air circulation. This natural process, also known as passive ventilation, is the best way to vent the attic. Experts suggest installing at least 1.5 square feet of vent for every 300 square feet of the attic floor. However, keep in mind that building codes may vary, so it’s best to check with your local building authority.
- Intake Vents: Intake vents are usually installed at the lowest part of the roof or under the eaves and serve as the point of entry for cool air into the attic.
- Exhaust Vents - Exhaust vents are usually installed at the roof’s peak, where hot or warm air from the attic comes out.
Why Roof Ventilation is Essential
