Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.

Slope of 5 12 roof pitch.

What is a 4 12 roof pitch. That is the roof s rise. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Conventional slope roof range between 4 in 12 and 8 in 12.

A low slope roof is anywhere from 2 in 12 to 4 in 12. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across. Simply locate a roof rafter board place the end of the level against the bottom edge and measure from the 12 inch mark vertically to the bottom edge of the rafter. 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.

Most roof s have a pitch in the 4 12 to 9 12 range. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. There are two main categories of roofing.

5 12 roof pitch angle 22 62 degrees. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. Roof slope style. 5 12 roof pitch to angle 22 62 degrees also referred to as 5 12 roof slope 5 on 12 5 to 12 and 5 12 roof angle.

This will give you the rise over run or pitch. It is often compared to slope but is not exactly the same. The run always remains constant at 12 inches. A flat roof has a slope of 2 in 12 or less.

For example if you measure 4 inches the pitch of your roof is 4 12. The combination of two numbers are used to display or show the roof pitch. 5 12 roof pitch equivalents roof rises 5 in a length of 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.
