Roof pitch is a term describing how steep or flat your roof slope is.
15 12 pitch roof.
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 provides the roof pitch multiplier for roofs of various slopes.
Roof pitch designations are comprised of two numbers indicating a ratio.
The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.
The combination of two numbers are used to display or show the roof pitch.

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.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
Pitch is the term used to describe the angle slope or slant of your roof.
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.
Or the colon can replace the slash as in 2 12 or 7 12.
