Soffit boards are located under the fascia board (the long straight board that your gutter system is attached to) and are an important part of your roof’s ventilation system. They have holes that allow fresh, cool air to enter from the bottom part of your roof.
Waynco Roofing, your trusted roofing company, further elaborates on the function of soffit boards below:
Soffit boards, along with air vents, provide ventilation for your roof and attic. Adequate roof ventilation is vital to preventing moisture damage. Without adequate ventilation, warm, humid air is trapped in your attic, creating a damp environment that’s the perfect breeding ground for mold and mildew.
As a general rule, there should be a square foot of net free area (NFA)—the area through which air can pass through— for every 300 square feet of floor area for attics with a vapor barrier and every 150 square feet of attic floor space for attics without a vapor barrier.
Important note: more ventilation isn’t necessarily better. That’s because the airflow in your attic needs to be balanced. If you’re not sure if your roof has enough intake or exhaust air vents, it’s best to have a roofer inspect it.
In addition to providing adequate ventilation, soffit boards also protect your roof’s rafters from rain and the elements. However, for soffit boards to do their job, they need to be durable enough to handle the local climate. That’s why it’s important to choose a soffit material that’s suited to your local climate. For instance, aluminum soffit boards are arguably the best option for homes in areas that receive high rainfall. That’s because aluminum is resistant to rot and other common moisture issues. To learn more about your options, consult one of your local roofers.
