How Do I Find The Pitch Of A Roof

How to calculate roof pitch.

How do i find the pitch of a roof. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. First enter the value of the rise and choose the unit of measurement from the drop down menu. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions. Here are the steps to follow for the roof angle calculator.

Enter any pitch or fraction of pitch to find angle. Divide the results by the number of 12 inch segments in your level. First measure 12 inches from one end of the level and make a mark. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

Divide the slope by two to get the pitch. Enter any angle or fraction of angle to find pitch. You can also estimate a roof pitch by eyeballing it from the ground from the gable side with a level and ruler. Pitch tan angle where angle is the roof pitch expressed in degrees.

Rise run pitch where pitch is expressed in percent. Here are a couple examples. Rafter rise run from the pythagorean theorem. How to measure roof pitch.

For example if you used a 24 inch level and your measurement was 12 inches the pitch in your roof is 6 in 12. Then enter the value of the run and choose the unit of measurement from the drop down menu.
