The definition of "slope" in the context of roofing refers specifically to the incline angle of a roof surface. Understanding this is crucial for various aspects of roofing, including water drainage, structural integrity, and the selection of appropriate roofing materials. A properly defined slope ensures that rainwater can effectively run off the roof rather than pooling, which can lead to leaks or other damage over time.

The other choices do not accurately capture the concept of slope. The highest point on a roof (often referred to as the ridge) relates more to the peak of the roofing structure rather than the overall slope. A projecting edge of a roof, such as an eave, refers to the extended portion of the roof, which is not specifically about the incline. The sloped edge of a gable roof describes a specific design feature but does not encompass the broader definition of slope itself, which is about the overall angle of the roof surface.
