What term describes the part of a roof that projects outward over the outside wall?

The term that describes the part of a roof that projects outward over the outside wall is referred to as the overhang. An overhang serves several important functions in roofing systems. It helps to protect the exterior walls from rain and snow, reducing the risk of water intrusion and damage to the siding and underlying structures. Additionally, it can offer shade to windows and doors, improving energy efficiency by keeping interiors cooler during hot weather.

The overhang also plays a role in overall roof aesthetics, adding to the visual appeal of a building. Its design can further reflect the architectural style of the structure.

While the other terms like parapet, fascia, and rake are related to roofing and eaves, they refer to different components. A parapet is a low wall that extends above the roofline, typically used for safety or decorative purposes. Fascia is the horizontal board that runs along the edge of the roof, supporting the lower edge of the roof and holding the gutters in place. The rake, on the other hand, refers to the sloped edge of a gable roof. These distinctions highlight the unique function and importance of the overhang in both practical and aesthetic terms.
