Rise run pitch where pitch is expressed in percent. You can also estimate a roof pitch by eyeballing it from the ground from the gable side with a level and ruler.

For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally.

Rafter rise run from the pythagorean theorem. Here are a couple examples. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Divide the results by the number of 12 inch segments in your level.

Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. First measure 12 inches from one end of the level and make a mark. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil. Pitch tan angle where angle is the roof pitch expressed in degrees.

Finally enter the value of the rafter length and. Enter any pitch or fraction of pitch to find angle. How to calculate roof pitch. First enter the value of the rise and choose the unit of measurement from the drop down menu.

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