1 4 pitch roof.

For example given a roof with a rise of 4 feet and a span of 24 feet the pitch is 1 to 6 pitch which can be expressed as the fraction of 1 6. There are two suggested ways to measure a roof pitch. An example of a roof pitch would be a 6 12 pitch which means that the roof rises 6 for every 12 inward towards the peak or ridge. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. The first is from the top of the roof. Roof pitch designations are comprised of two numbers indicating a ratio. There is no standard universal roof pitch roof pitch varies depending on culture climate style and available materials in the usa the range of standard pitches is anywhere between 4 12 and 9 12 in the uk the typical house has a pitch between 40 50 although 45 should be avoided.

The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. Thus pitch is typically greater in areas of high rain or snowfall. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. If the pitch of a roof is 1 4 how many feet in the horizontal direction correspond to a rise in 3 feet.

Roof pitch or slope tells you how many inches the roof rises for every 12 inches in depth. Flat and nearly flat roofs a pitch of 1 in 12 or 2 in 12 cannot be covered with shingles or shakes of any material since there is not enough angle to combat the danger of blow off. Definitions vary on when a roof is considered pitched. The exact roof slope in degrees is given by the arctangent.
