What term describes the slant of a roof?

The term that describes the slant of a roof is "slope." In roofing terminology, slope refers to the angle or steepness of the roof surface, typically calculated as a ratio of the vertical rise to the horizontal run. This measurement is crucial in construction and architecture, as it impacts water drainage, roofing materials, and energy efficiency. A roof with an appropriate slope ensures that rainwater runs off properly, reducing the risk of leaks and structural damage. Therefore, recognizing slope is vital for both design and practicality in building projects.

The other terms relate to roofing but do not specifically define the angle of a roof surface in the same way.
