Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. The run always remains constant at 12 inches.

This forms an angle of 18 5 between the horizontal section and the roof and creates a gentle incline that is seen as a midpoint between a low pitch and medium pitch roof.
