Roof slope pitch rise run typw walkability table.

For roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Roof pitch varies depending on culture climate style and available materials.
