The Slope Of A Roof Is

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

The slope of a roof is. The slope of the roof is determined by the vertical rise in inches for every horizontal 12 inch length or run a common formula is. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. The pitch of a roof is its vertical rise over its horizontal span. X rise 12 run this means that for ever 12 inches horizontally the roof rises x number of inches.

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. 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 refers to the slope which the rafter creates. Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run.

Roof pitch in layman s language simply refers to the steepness of the roof. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Roof pitch calculator results explained.

Slope is the incline of the roof expressed as a ratio of the vertical rise to the horizontal run where the run is some portion of the span. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof. The pitch of a roof is arrived at by dividing the vertical rise and its horizontal span or what people in the roofing industry would refer to as the slope.

This ratio is always expressed as inches per foot.
