How roof pitch is calculated.

Roof pitch is used to describe the slope or angle of the roof. You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof. Placing a ladder near the roof you will put a level a foot or so up on the roof hold it level and measure from the 12 inch mark straight down.
