8 12 pitch 33 75 degrees.
Roof pitch 21 degrees.
With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch.
Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12.
Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.
On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
Active ventilation products.
To see roof pitch visual examples how to determine pitch.

Roof pitches ranging from 0 12 0 degrees to 21 12 60 26 degrees.
However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement.
If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length.
Pitch tan angle where angle is the roof pitch expressed in degrees.
The value displayed as the rise will be your x.
Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
You can also calculate roof pitch even without using a roof slope calculator.
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 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.
Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees.
Use the following formula which also describes a right triangle.
A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.
