Pitch Of A Roof Refers To The Ratio Of

Most people interested in roof pitch are actually measuring the slope which is the most useful measurement when considering roofing material and rainwater.

Pitch of a roof refers to the ratio of. A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a 4 in 12 slope. Angles are pretty hard to measure but roof pitch is simple. 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. The pitch of a roof refers to its steepness and states how many inches the slope rises for every 12 inches it runs horizontally.

I say this because it s quite an important distinction. The pitch of a roof is its vertical rise over its horizontal span. This is the slope of geometry stairways and other construction disciplines or the trigonometric arctangent function of its decimal. An average and easy roof pitch to work with is a 5 12.

The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run. Carpenters don t refer to the angle of a roof such as 30 or 45 but to the pitch of the roof which is just the ratio of vertical to horizontal measurements.
