What Is Fascia?

The fascia runs along the eave, capping the rafter tails and tying their ends together so they hold a straight line. Wood is common, and it may be wrapped in aluminum or replaced by PVC or composite trim. The gutter fastens to it, the drip edge sits at its top, and the soffit meets its bottom edge. A second board hidden behind it, the subfascia, sometimes carries the load, so wrapped fascia can look sound while the wood beneath is not.

Fascia is a reading tool from the street. Dents in aluminum wrap, like dents in gutters and vents, are evidence of hail that can be photographed without climbing, and rot at the board’s lower edge or at gutter joints points to chronic overflow. During a roof replacement, rotten fascia is a common change order, priced by the linear foot. Whether an insurer pays depends on whether the damage came from a covered event or from long-term moisture.

People mix up fascia, soffit, and eave. The fascia is the vertical face, the soffit is the horizontal underside, and the eave is the edge of the roof itself. Another mistake is assuming a roof contract includes fascia work; unless it is written in, trim carpentry is separate. Painting over rotted fascia is a patch that hides the problem for a season.
