The calculator above can handle much of this math.
Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10.
Select inches to enter decimal inches or millimeters for metric.
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.
Directly measure roof pitch angle and calculate pitch and angle on phone or tablet.
The pitch of this roof is 4 8 12.
Set bevel gauge directly from phone or tablet screen.
After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.
Now divide the rise by the multiplier to get the pitch eg.
48 10 4 8.
Roof angles and rafter plumb cuts.
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.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
You have to pay higher cost for steeper pitch.
Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees.
In the uk the typical house has a pitch between 40 50 although 45 should be avoided.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
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.
Contemporary houses often have flat roofs which shouldn t be completely flat but should be around 1 40.
12 pitch 45 degrees 11 pitch 42 5 degrees 10 pitch 40 degrees 9 pitch 37 degrees 8 pitch 33 75 degrees 7 pitch 30 5 degrees 6 pitch 26 5 degrees 5 pitch 22 5 degrees 4 pitch 18 5 degrees 3 pitch 14 degrees 2 pitch 9 5 degrees 1 pitch 4 5 degrees 0 pitch 0 degrees.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
8 12 pitch 33 75 degrees.
