If a roof or ramp rises 4 in a length of 12 the pitch is 4 in 12 which is 18 43 or 33 33 grade enter base length to calculate rise and diagonal for current pitch angle. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. Another method to find the roof pitch is to go into the attic and measure the rise. One method to find the pitch is to climb on the roof and measure the rise for a 12.

Position your level against the roof until the bubble of the vial sits between two lines. Directly measure roof pitch angle and calculate pitch and angle on phone or tablet. Check the surface of the.

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. Select inches to enter decimal inches or millimeters for metric.

The value displayed as the rise will be your x. To see roof pitch visual examples how to determine pitch.
