What is a Fascia
Fascia is a term which generally describes any vertical surface which spans across the top of columns or across the top of a wall. From the Latin word, meaning "band" or "doorframe"; in architecture. The word is pronounced with the "long-a" sound /feɪʃɪɑ/, rhyming with the Japanese word geisha.
Specifically, used to describe the vertical "fascia board" which caps the end of rafters outside a building, which can be used to hold the rain gutters. The finished surface below the fascia and rafters is called the soffit or eave. A soffit is also often installed between the ceiling and the top of wall cabinets in a kitchen, set at a 90 degree angle to the horizontal soffit which projects out from the wall.
