The term "pitch" in relation to roofs specifically denotes the steepness or slope of the roof. It is a critical measurement as it impacts drainage, the aesthetic appeal of the building, and often the overall structural design. Pitch is commonly expressed as a ratio comparing the vertical rise to the horizontal run, for example, a 4:12 pitch means the roof rises 4 inches for every 12 inches of horizontal run.

Understanding pitch is essential for carpenters since it affects not only the design but also the type of roofing material that may be appropriate for specific pitches, as some materials are better suited to steeper or shallower angles to ensure proper water run-off and minimize the risk of leaks.
