Pitch is the term used to describe the angle slope or slant of your roof.
15 12 pitch roof.
For a more detailed explanation of the roof pitch multiplier see how to find the area of a sloped roof if you know the roof pitch in degrees find the secant of the slope using a scientific calculator for example if the roof pitch is 45 then sec 45 1 414213.
Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.
Or the colon can replace the slash as in 2 12 or 7 12.
Roof pitch defined and explained.
Roof pitch is a term describing how steep or flat your roof slope is.
A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.
The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.
Thus pitch is typically greater in areas of high rain or snowfall.
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.

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.
The exact roof slope in degrees is given by the arctangent.
Roof pitch designations are comprised of two numbers indicating a ratio.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

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.
