Like most exterior components, it’s important to understand the location and purpose of soffit and fascia. Fascia forms an end cap on your trusses or rafters and along eaves, and supports your gutters. Soffit is the area underneath the overhanging eaves and/or rakes. Soffit provides both an aesthetic and functional purpose. Functionally, it serves to close in the rafters while providing ventilation to the attic. Many different styles and materials are available in the marketplace to customize the look of your home or building.
