The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow.

The combination of two numbers are used to display or show the roof pitch. The steep roof of the tropical papua new guinea longhouse for example sweeps.

Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. Thus pitch is typically greater in areas of high rain or snowfall. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.

The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.
