Pitch Of A Roof From The Side
A gable roof is probably the most versatile type of shed roof and the most common as it can handle any type of pitch.
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. A gable roof has the same pitch on each side as well as the same length. The pitch of a roof is its vertical rise over its horizontal span. Roof pitch is used to describe the slope or angle of the roof.
This is the slope of geometry stairways and other construction disciplines or the trigonometric arctangent function of its decimal. 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. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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 roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.
