Rafter rise run from the pythagorean theorem. Rise run pitch where pitch is expressed in percent. Plug in the values and solve for the c term. One method to find the pitch is to climb on the roof and measure the rise for a 12 run.

Roof pitch calculator is determined by the number of inches it rises vertically for every 12 inches it extends horizontally. How to calculate roof pitch. Pitch tan angle where angle is the roof pitch expressed in degrees.

Let the other side b 15. Let the slope the hypotenuse c. Also referred to as roof slope or roof slant so what does the 7 12 in the example to the right mean. Even if you want to use a flat roof pitch calculator system you will be able to find one.

Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. Let one side a 8. Enter any angle or fraction of angle to find pitch. Then enter the value of the run and choose the unit of measurement from the drop down menu.
