The soffit is the underside of the roof overhang, the surface you see when you stand under the edge of the roof and look up. Besides finishing off the overhang, the soffit usually houses the intake vents that pull fresh air into the attic. A healthy, vented soffit is a key part of attic ventilation, and a damaged or rotted soffit is often the first visible sign of a water or pest problem at the roof's edge.
When you look up at the edge of a house where the roof extends past the wall, the flat panel tucked under that overhang is the soffit. It closes off the space between the wall and the edge of the roof, keeping out rain, animals, and insects while giving the roofline a finished look. It is easy to overlook because it sits in shadow under the eave.
The soffit does more than look neat. In most homes it carries the intake vents for the attic, either as small vented panels or a continuous perforated strip. Those vents let cool outside air flow up into the attic, where it pushes hot air out through the ridge vent above. Without working soffit vents, attic ventilation stalls no matter how good the ridge vent is.
For a homeowner, the soffit is a useful early-warning surface. Because it sits at the edge where water tends to collect if drip edge or gutters fail, a stained, peeling, or soft soffit often signals a moisture problem before any leak shows up inside. Squirrels and birds also target weak soffits to get into an attic. Catching soffit damage early usually means a smaller, simpler repair.
