How to determine roof slope angle.

A 12 12 pitch roof has a pitch angle of 45. Roof pitch is used to describe the slope or angle of the roof. The roof pitch is the slope of the rafter. 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.

After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. 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.
