Understanding Soffit and Fascia

Soffit and fascia are two terms that are often used interchangeably, but they serve different purposes in a building's exterior cladding system. The soffit is the underside of the roof overhang, while the fascia is the horizontal board that runs along the edge of the roof.

Both the soffit and fascia play a critical role in protecting the building from the elements, and their installation requires careful attention to detail. The soffit provides ventilation to the roof space, while the fascia helps to direct water away from the building.
