Pitch Of A Roof Refers To The Ratio Of

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.

Pitch of a roof refers to the ratio of.

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. It can be expressed in degrees or as a percentage but is often seen in ratio form such as 3 12 or 6 12. The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run. Angles are pretty hard to measure but roof pitch is simple.

A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a 4 in 12 slope. Most people interested in roof pitch are actually measuring the slope which is the most useful measurement when considering roofing material and rainwater. An average and easy roof pitch to work with is a 5 12. Slope is the correct term for the ratio of vertical to horizontal distance on a particular plane of the roof.

The pitch of a roof is its vertical rise over its horizontal span. If the rise is 6 inches for every 12 inches of run then the roof slope is 6 in 12 the slope can be expressed numerically as a ratio.
