The combination of two numbers are used to display or show the roof pitch. Sometimes pitch is also expressed in. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

Roof pitch refers to the slope which the rafter creates. 0 pitch 1 00x the roof area. The best roof pitch depends on the style of roof you are going for. For a gothic style the rafters must equal the span 60 while an elizabethan style requires the rafters to be longer than the span.

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. If a roof rises 1 in a length of 12 this is 1 12 roof pitch. 1 12 roof pitch angle 4 76 degrees. Commonly used roof pitches were given names such as greek.

Historically roof pitch was designated in two other ways. The ridge height is 1 9 to 1 7th the span an angle of 12 5 to 16. This pitch might be as low as 1 12. On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.

Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. It was fashionable for modern style homes built in the 1960s to have little pitch just a barely negligible slope to help drain water. 1 pitch 1 01 2 pitch 1 02 3 pitch 1 03 4 pitch 1 05 5 pitch 1 085 6 pitch 1 12 7 pitch 1 16 8 pitch 1 21 9 pitch 1 25 10 pitch 1 31 11 pitch 1 36 12 pitch 1 42.

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. A ratio of the ridge height to the width of the building span and as a ratio of the rafter length to the width of the building. A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. 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.
