Roof Pitch ExplainedRoof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page.
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. We included a roof pitch chart below the 7-12 example image and the calculator below that.
