The underside of the roof overhang — the horizontal surface visible looking up under the roof edge.
The horizontal underside of the roof overhang (eave) that spans between the exterior wall and the fascia board. Soffits are typically constructed from vinyl, aluminum, wood, or fiber cement panels and are often perforated or vented to allow outside air to enter the attic for ventilation. Proper soffit venting is paired with ridge venting to create continuous attic airflow.
Soffit appears in both the roofing and exterior trim scope, which creates scope-gap risk at bid time if the GC does not clearly assign it between the roofer, framer, and siding sub. Material choice and venting requirements drive the cost, and because soffit ties directly into attic ventilation, an estimator must coordinate it with the ridge-vent scope so the assembly is priced as a complete system rather than disconnected pieces.
During scope review, the estimator notices the soffit could fall to either the siding sub or the roofer, so the bid explicitly assigns vented aluminum soffit and fascia to the siding sub to close the gap before the GC issues addenda.
