In roofing it is expressed in inches of vertical rise over inches of horizontal run. The roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12. It is expressed as x y where x rise and y run for example 4 12 or 5 12 and so on. As stated in the video speed squares have useful markings on them from 0 to 12.

Worth noting is that the higher the first number in the equation is the steeper the pitch of your shed roof will be. A 4 12 pitch being 4 inches of vertical rise over one foot or 12 inches of horizontal run. This image shows a relatively shallow roof pitch of 15 degrees. In the simplest possible terms shed roof pitch is defined as the amount of rise per foot of run.

Having a steeper pitched roof allows for more space in a shed loft. The loft space would be much larger with a roof pitch of 45 degrees.
