Roof pitch roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

Roof pitch is given as the number of inches in height change over the distance of one foot. Dividing by 12 gives the ratio of inches in rise per distance. The total amount of roofing material you need is 17 300 1 730 19 030 square feet. A 12 in 12 pitch is a steep 45 degree angle roof.
