Which term is used to refer to the angle of inclination of a roof?

The term used to refer to the angle of inclination of a roof is "pitch." In the context of roofing, pitch describes how steeply the roof rises in relation to its horizontal span. It is a critical aspect of architectural design and construction, as it impacts water drainage, the type of roofing materials that can be used, and the overall aesthetic of a structure. The pitch is often expressed as a ratio, such as 4:12, which means that for every 12 horizontal units, the roof rises 4 units vertically.

Elevation generally refers to the height of a structure or land above a base level, usually sea level, and does not specifically relate to the angle or slope of a roof. Gradient typically describes the slope of land or a road but is less specific in the context of roofing than pitch. Inclination can refer broadly to an angle of slant but is not the specialized term used in construction and roofing terminology. Thus, pitch is the most precise and commonly utilized term for describing the angle of inclination of a roof.
