Measure the vertical distance from roof to level.
Hot to measure pitch of roof.
Take a measurement of 12 inches using a level.
Roof pitch is often expressed as a ratio between rise and run in the form of x 12.
The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
Move the tape measure along the the roof until it hits the level at exactly the 12 inch mark.
First measure 12 inches from one end of the level and make a mark.
It is often compared to slope but is not exactly the same.

Measure from the roof.
The rise is the vertical length from the top of a stud wall to the peak of the roof.
Hold the 0 mark of the tape measure against the roof.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.
Extend it upward so it is perpendicular to the level.
8 inches and you have an 8 in 12 pitch.
