Which term refers to the degree of slope of a roof?

The term that refers to the degree of slope of a roof is "pitch." In roofing and construction, pitch is defined as the ratio of the vertical rise of the roof to the horizontal run, typically expressed in inches per foot. This concept is crucial for determining how water drains off the roof, potentially affecting both the roof's durability and the choice of roofing materials.

Understanding pitch is also essential when considering factors such as climate, local building codes, and aesthetic preferences. For example, steeper pitches are often more effective at shedding water and snow, while shallower pitches may require different roofing solutions to avoid water pooling.

Sheathing, joists, and slope may seem relevant, but they do not directly define the degree of roof incline. Sheathing refers to the boards or sheets that are attached to the roof framing, providing a base for the roofing material. Joists are horizontal supports used in the construction of floors or ceilings, not roofs specifically. While "slope" is a general term that might be used in everyday conversation, "pitch" is the technical term recognized in construction and roofing industries for this specific measurement.
