This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. How to measure roof pitch. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. Enter any angle or fraction of angle to find pitch.

How to calculate roof pitch. Here are a couple examples. Divide the slope by two to get the pitch. First measure 12 inches from one end of the level and make a mark.

Here are the steps to follow for the roof angle calculator. First enter the value of the rise and choose the unit of measurement from the drop down menu.
