Angle the angle of a roof is the same as the roof s slope except instead of being. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

The triangle diagram will be re drawn to scale with all dimensions marked. Roof pitch calculator results explained. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Divide the first part of the ratio by 12 to work out the pitch.

To convert between american roofing ratios and pitch degrees follow these steps. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Pitch angle precision color. Find the inverse tangent of the pitch to find the angle in degrees.

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. 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. Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. What degree angle is a 12 12 pitch roof.
