💡 Pro Tip

Use vented soffit panels. Attic ventilation requires air intake at the eaves (soffit) and exhaust at the ridge. Sealed soffits trap moisture, leading to attic mold and wood rot.

Frequently Asked Questions

Q: What is the difference between soffit and fascia?

Fascia is the horizontal wooden board that runs along the roof edge where gutters mount. Soffit is the under-hanging panel that covers the rafter bottoms.

Q: How do you calculate soffit square footage?

Multiply total roof perimeter (eave length) by the overhang width. Add 10% for corner waste and cuts.
