What does the term 'soffit' refer to?

The term 'soffit' refers to the underside of a horizontal surface that projects beyond a wall line. This architectural feature is commonly found in areas such as the eaves of a roof, where it creates a finished appearance and can also house ventilation. Soffits are important for both aesthetic and functional reasons, as they can help protect the structural elements of a building from weather exposure and contribute to proper airflow, especially in attic spaces. Understanding this term is important for recognizing different components in construction and home design, particularly in relation to roofing and exterior detailing. This enhances awareness of how these features affect the overall integrity and presentation of a building.
