Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

How much drop in 14 roof.

As aforementioned there is no standard pitch of a roof. Roof pitch in layman s language simply refers to the steepness of the roof. The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run. However you can only use this pitch with built up roofing or specialized synthetic roofing.

The combination of two numbers are used to display or show the roof pitch. The pitch of a roof is arrived at by dividing the vertical rise and its horizontal span or what people in the roofing industry would refer to as the slope. Anything less than one eighth of an inch may pool on the roof. Here are some of the common shapes that top roofs today.

See the image below for more explanation on rise run and pitch. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Roof shapes have evolved through history in different regions of the world from flat to steeply pitched.

Some building codes start at one quarter of an inch per foot or two percent. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. A 12 in 12 pitch is a steep 45 degree angle roof. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

Express roof pitch as the ratio of the amount of the vertical rise of a roof or rise over the corresponding horizontal distance or run you write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run. However an ideal roof drop per foot should be at least one eighth to one quarter of an inch per foot.

Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. 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. How roof pitch manifests itself in various roof types.
