Without adequate roof ventilation, warm, humid air is trapped in your roof and attic. Trapped humid air is a problem because it increases the strain on your HVAC system and creates a damp environment that’s the perfect breeding ground for mold. That’s why it’s important to make sure your roof and attic have enough exhaust and intake air vents.
How Many Air Vents Does Your Roof and Attic Need?
As a general rule, attics with a vapor barrier should have one vent per every 300 square feet of attic area while attics with no vapor barrier should have one vent for every 150 square feet.
Not All Air Vents Can Provide the Same Level of Ventilation
Keep in mind not all air vents can provide the same level of ventilation. Remember: there’s no such thing as a one-size-fits-all approach in home improvement projects, and stucco remediation and roofing projects are no exception.
What Are the Most Widely Used Types of Air Vents?
- Ridge vents – Ridge vents are a smart choice if you want to keep your home’s curb appeal intact. Since ridge vents are installed along the roof peak, they won’t draw attention to themselves or disrupt your roof’s design.
- Box vents – Since box vents don’t provide a lot of venting space, you will need to install several of them to provide adequate ventilation for your roof.
- Turbine vents – Turbine vents are highly efficient, but since they rely on wind to draw warm, humid out, they won’t provide any ventilation when the winds stop.
To learn more about your vent options, consult one of your local roofing contractors. Since they’re more familiar with the local climate and building codes, they can make better recommendations.
