Position your level against the roof until the bubble of the vial sits between two lines. A gable roof with its end parapet walls below extended slightly upwards and shaped to resemble steps. In other words if a roof has a span of 4 meters and a rise of 2 meters the pitch would be 1 2 or one half of the pitch. Low slope roofs are from 0 to 3 12 in pitch.

See low slope roofing. The way pitch also known as roof slope is measured is rise over run. See also roof pitch crow stepped corbie stepped stepped gable. The result of joining two or more gabled roof sections together forming a t or l shape for the simplest forms or any number of more complex shapes.

A hip roof has slopes on all four sides. Also known as pitched or peaked roof gable roofs are some of the most popular roofs in the us. So if your roof rises 4 inches for every 12 inches of horizontal length then the pitch of your roof is expressed as 4 12.

Take a measurement of 12 inches using a level. Take the measurement of the vertical.
