0 pitch 1 00x the roof area.
0 3 roof pitch.
The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.
Roof pitch is used to describe the slope or angle of the roof.
Since this is a flat roof or nearly flat roof.
A completely flat roof is a poor design as water and snow will collect on it eventually leading to your roof collapsing in from the weight of it all.

Definitions vary on when a roof is considered pitched.
The exact roof slope in degrees is given by the arctangent.
The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
The smallest pitch of a roof is 0 5 12.
Roof pitch designations are comprised of two numbers indicating a ratio.
Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow.
Or the colon can replace the slash as in 2 12 or 7 12.
Thus pitch is typically greater in areas of high rain or snowfall.
You can go by the measurements taken by walking the roof.
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.
