Your soffit is the exposed underside surface between your building and roof edge, whereas your fascia is the vertical edge connected to the ends of the roof. During heavy rain and high wind, the system prevents water from blowing into your home or business and stops water from collecting in certain areas.
As the first line of defense, your soffit and fascia are often the first part of a roof that requires repair or replacement. However, keeping the soffit and fascia in good condition with frequent sealing and caulking can help extend a roof’s lifetime.
