What term is used to describe the slope of a roof?

The term used to describe the slope of a roof is "pitch." Pitch specifically refers to the steepness or angle of the roof and is typically expressed as a ratio that compares the vertical rise to the horizontal run. For example, a roof with a pitch of 4:12 means it rises 4 inches for every 12 inches of horizontal distance. Understanding pitch is essential in construction and appraisal as it affects both the aesthetics and functionality of a roof, including water drainage and the potential for snow accumulation.

The other terms may relate to concepts of slope or inclination but do not specifically refer to roofing. "Incline" is a general term for any slope, "angle" refers to the measurement of the space between two intersecting lines, and "grade" often describes the degree of rise or fall over a distance, commonly used in contexts like road construction rather than roofing. Hence, "pitch" is the most accurate and specific term in this context.
