1 Pitch Roof

A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof.

Roofs on victorian era houses were often sharply angled with a steep pitch. Think of a classic addams family haunted house with its soaring peaks and you have a. 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. 0 pitch 1 00x the roof area.

This pitch might be as low as 1 12. It was fashionable for modern style homes built in the 1960s to have little pitch just a barely negligible slope to help drain water. Definitions vary on when a roof is considered pitched. Since this is a flat roof or nearly flat roof.

1 12 roof pitch angle 4 76 degrees. A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. Thus pitch is typically greater in areas of high rain or snowfall.

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. Visually this roof appears flat. Sometimes pitch is also expressed in. 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.

The exact roof slope in degrees is given by the arctangent. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. In degrees 10 2 in 12 or 1 in 6 is considered a minimum. The maths behind this number is that it is the square root of rise run 2 1.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. You can go by the measurements taken by walking the roof. Roof pitch refers to the slope which the rafter creates.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. The combination of two numbers are used to display or show the roof pitch.
