It will give you a roof pitch angle and a ratio between rise and run in the form of x 12. What is roof pitch. Roof pitch calculator results explained. The roof pitch is the slope of the rafter.

Homes and other buildings have roofs with slopes ranging from no slope or flat to very steep slopes. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. 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.
