Pitch And Slope Of A Roof

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.

Pitch and slope of a roof.

Roof pitch is used to describe the slope or angle of the roof. Understanding your roof s pitch and slope. If the slope is 4 12 the pitch for the 24 foot span is 1 6. For example a roof with a pitch.

By knowing the pitch of your roof you will know what type of products can be used and the best ways to go about applying them. Slope is the correct term for the ratio of vertical to horizontal distance on a particular plane of the roof. Definitions vary on when a roof is considered pitched. Roof pitch calculator results explained.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Although there is no single standard roof pitch used on all sloped roofs factors such as roofing materials and local climate help to determine the appropriate range of pitches for a given building. Roof pitch refers to the slope which the rafter creates. Most people interested in roof pitch are actually measuring the slope which is the most useful measurement when considering roofing material and rainwater.

If the pitch is 1 3 the slope is 8 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Roof pitch is a measurement of a roof s slope expressed as a ratio. 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.

Often you express roof pitch as the ratio between the rise and the run in the form of x 12. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. The exact roof slope in degrees is given by the arctangent. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow.

In degrees 10 2 in 12 or 1 in 6 is considered a minimum. Angle the angle of a roof is the same as the roof s slope except instead of being. Using the illustration above and information we just learned about slope and pitch we can see that a 2 12 slope can be expressed as 1 12 pitch assuming the span is twice the length of the run. 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 this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
