Includes result for hip valley factor slope factor and the roof slope in degrees.
A roof with a 6 rise for every 12 run has a 6.
Rise and run means that a 6 12 pitch roof has 6 of rise vertical for each foot of run horizontal.
A pitch of 3 12 means a rise of 3 for every 12 of run so 3 x 14 42.

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 is used to describe the slope or angle of the roof.
A roof s pitch is determined by how much it rises for every foot it runs.
Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.
Thus a moderate 6 in 12 roof pitch means the roof rises 6 inches for every 12 horizontal inches it runs.
