The answer to 'difference between fascia' is that fascia and soffit are two distinct components of a home's roofing system, each serving a specific purpose. Fascia is the vertical board that runs along the edge of the roof, providing a finished edge and support for the roofing material. Soffit, on the other hand, is the horizontal board that runs underneath the roof's overhang, covering the exposed underside of the roof and helping to ventilate the attic space.
Fascia is typically made of wood, vinyl, or aluminum, and its primary function is to protect the roof's edge from water damage and provide a surface for attaching gutters. Soffit is usually made of the same materials as fascia and plays a crucial role in maintaining proper airflow in the attic, helping to prevent moisture buildup and potential mold or mildew issues.
