Multiply the number of roofing squares for a medium pitch roof by 1 12 to 1 25 or by 1 3 to 1 42 for a high pitch roof to get the square roof area.
A 12 in 12 pitch is a steep 45 degree angle roof.
The pitch of the roof is the rise over a 12 inch run.
The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
Roof pitch multipliers are extremely useful in estimating the amount of material required to fit your new sloped.
