You can also estimate a roof pitch by eyeballing it from the ground from the gable side with a level and ruler. First enter the value of the rise and choose the unit of measurement from the drop down menu. Rise run pitch where pitch is expressed in percent. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

Pitch tan angle where angle is the roof pitch expressed in degrees. First measure 12 inches from one end of the level and make a mark. Divide the slope by two to get the pitch. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

Here are a couple examples. Then enter the value of the run and choose the unit of measurement from the drop down menu. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. Enter any pitch or fraction of pitch to find angle.

Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. How to measure roof pitch. How to calculate roof pitch. Enter any angle or fraction of angle to find pitch.
