Roof pitch is a term describing how steep or flat your roof slope is. Think of a classic addams family haunted house with its soaring peaks and you have a. A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.

It was fashionable for modern style homes built in the 1960s to have little pitch just a barely negligible slope to help drain water. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. 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.

The exact roof slope in degrees is given by the arctangent. 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. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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. Thus pitch is typically greater in areas of high rain or snowfall. This pitch might be as low as 1 12. 1 12 roof pitch angle 4 76 degrees.

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. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. Definitions vary on when a roof is considered pitched. Roof pitch refers to the slope which the rafter creates.

Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Visually this roof appears flat. The maths behind this number is that it is the square root of rise run 2 1. Roofs on victorian era houses were often sharply angled with a steep pitch.

Since this is a flat roof or nearly flat roof. If a roof rises 1 in a length of 12 this is 1 12 roof pitch.
