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.
Roof pitch 26 degrees.
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.
Directly measure roof pitch angle and calculate pitch and angle on phone or tablet.
Enter any pitch or fraction of pitch to find angle.
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.
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.
First convert the pitch to a slope.
One engineer recommends a 12 12 pitch for the new roof while another recommends a 7 12 pitch.
Select inches to enter decimal inches or millimeters for metric.
How to convert roof pitch to degrees.
Roof angles and rafter plumb cuts.
Enter any angle or fraction of angle to find pitch.
For a gothic style the rafters must equal the span 60 while an elizabethan style requires the rafters to be longer than the span.
In snowy areas your roof should be at least 10 12 40 to allow snow to shed while the safest roof pitch in very windy areas is between 4 12 6 12 18 5 26 5.
Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof.
Roof pitch visual examples.
Visit this page on your phone to directly measure pitch and angles.
Enter base length to calculate rise and diagonal for current pitch angle.
The ibhs recommends a 4 to 6 pitch roof.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
A 7 12 pitch equals 30 26 degrees.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope.
