Common roof pitch angles used by builders.

Roof pitch designations are comprised of two numbers indicating a ratio. Pitch angle incline slope they all can be used to refer to the steepness of a roof. Historically roof pitch was designated in two other ways. In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally.

Although there is no single standard roof pitch used on all sloped roofs factors such as roofing materials and local climate help to determine the appropriate range of pitches for a given building. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. The ridge height is 1 9 to 1 7th the span an angle of 12 5 to 16. Or the colon can replace the slash as in 2 12 or 7 12.

Roof pitch is a measurement of a roof s slope expressed as a ratio.
