1. What is the minimum and maximum h

The pitch of a roof is a ratio describing its rise to its run; however, the second quantity is always 12. Therefore, a pitch of 2 : 12 means that the roof rises 2 inches for every foot of run. Also, the pitch of a roof is always given as a positive ratio. Think: a roof slanting downward when viewed from one side will be slanting upward when viewed from the opposite side.
In the United States it is standard to have a roof pitch of 4 to 12, although the pitch can go as high as 60 to 12. Use the slider to compare the steepness of some roof pitches.
