How To Find The Slope Or Pitch Of A Roof

Although the terms pitch and slope are often used interchangeably they have two different meanings.

How to find the slope or pitch of a roof.

These articles explain various methods for measuring all roof data. Once you know the roof slope multiplier for a particular slope you can use it to find the actual area of any size sloped roof with the same slope. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

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 slope find the pitch of the roof shown. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. The span of the roof is the distance from one wall s top plate to another wall s top plate stretching across the length of the roof.

So in this case for every 12 inches the roof goes across horizontally b while rising 6 inches a there s actually 13 416 inches of roof c. This article series gives clear examples just about every possible way to figure out any or all roof dimensions and measurements expressing the roof area width length slope rise run and. Algebra linear equations solution. Roof slope or pitch rise run area and other features.

Roof pitch is used to describe the slope or angle of the roof. 8 feet by 15 feet log on. The pitch is the measurement of the rise of the roof to the span of the roof and is expressed as a fraction. 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.

Roof pitch refers to the slope which the rafter creates. 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.
