The correct definition of an "eave" in roofing terms is a projecting edge of a roof. Eaves serve important functions in a roofing system, primarily by directing rainwater away from the sides of a building, preventing water damage and issues with erosion.

Eaves typically overhang beyond the exterior walls, which not only aids in water management but can also contribute to the aesthetic appeal of the structure. They can be critical for ventilation as well, as they help to encourage airflow into the attic space. Understanding the function and design of eaves is crucial for effective roofing construction and maintenance.

The other definitions highlight different aspects of roofing: a sloped edge might refer to a part of the roof’s design but does not capture the specific nature of eaves. The highest point on a roof refers more to the ridge, and the inclined external angle formed by roof sides describes a valley or the intersection of two roof planes rather than the eaves themselves.
