Roof Pitch Conversion Table

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.

Roof pitch conversion table.

In essence a roof pitch chart is provided as a rough guide usually by a roofing company to help you see what the average roof pitches tend to be. For roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1. Now divide the rise by the multiplier to get the pitch eg. Pitch tan angle use this when you express the angle of the roof pitch in degrees what is the standard pitch of a roof.

Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10. 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. Roof slope expressed as rise. There are many tools out there.

To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference. The pitch of this roof is 4 8 12. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. What is a roof pitch chart.

Roof pitch and corresponding angles. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. 48 10 4 8. The calculator above can handle much of this math.
