The fascia and soffit are, respectively, the vertical and horizontal surfaces of what most people refer to as the eaves or roof overhang of a home. The upper part of the fascia at the intersection with the roof has a continuous metal “drip strip” running along it, the bottom edge of which is bent away from the fascia to cause water running off the roof to drip off the lower edge rather than running down the fascia.

    The soffit typically has some form of ventilation openings—either small screen panel inserts or the entire soffit has perforations—for ventilation of the attic. Also, most fascia (sometimes spelled “facia”) and soffit assemblies today have an aluminum cladding to protect the wood underneath from moisture intrusion and rot.
