Last updated july 10 2020 the following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
Slope of 5 12 roof pitch.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
It is often compared to slope but is not exactly the same.
This will give you the rise over run or pitch.
That is the roof s rise.
A flat roof has a slope of 2 in 12 or less.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
For example if you measure 4 inches the pitch of your roof is 4 12.
The run always remains constant at 12 inches.
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.
In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.
Simply locate a roof rafter board place the end of the level against the bottom edge and measure from the 12 inch mark vertically to the bottom edge of the rafter.
5 12 roof pitch equivalents roof rises 5 in a length of 12.
What is a 4 12 roof pitch.
Conventional slope roof range between 4 in 12 and 8 in 12.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
Most roof s have a pitch in the 4 12 to 9 12 range.
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.
5 12 roof pitch angle 22 62 degrees.
The combination of two numbers are used to display or show the roof pitch.
Roof pitch is a term describing how steep or flat your roof slope is.
A low slope roof is anywhere from 2 in 12 to 4 in 12.
There are two main categories of roofing.
Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.
5 12 roof pitch to angle 22 62 degrees also referred to as 5 12 roof slope 5 on 12 5 to 12 and 5 12 roof angle.
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.
