Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

Pitch of a roof from the side.

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. A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain. However from the wind uplift mitigation perspective a 7 12 roof slope can be considered as a two story building due to the higher overall steepness and profile of the roof.

The pitch of a roof is its vertical rise over its horizontal span. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. What is the standard pitch for a roof. Since slope affects how roof systems are installed including dictating which type of roof covering material can be applied understanding how to measure the slope of a roof may be valuable to a home inspector.

However most often a ratio of pitch also fraction is slang used for the more useful slope of rise over run of just one side half the span of a dual pitched roof. Roof pitch is used to describe the slope or angle of the roof. There is no standard universal roof pitch roof pitch varies depending on culture climate style and available materials in the usa the range of standard pitches is anywhere between 4 12 and 9 12 in the uk the typical house has a pitch between 40 50 although 45 should be avoided.
