Roof Pitch

Roof Pitch

How To Figure Roof pitch, refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the 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".

*This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. If this isn't practical then perform the same measurement on the underside of the roof.
