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.

Pitch tan angle use this when you express the angle of the roof pitch in degrees what is the standard pitch of a roof. Roof slope expressed as rise. 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. There are many tools out there.

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. 48 10 4 8. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. To see what the degree equivalents are for standard rise in run roof pitches see our page quick reference.

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. 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. 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.

The calculator above can handle much of this math. The pitch of this roof is 4 8 12. What is a roof pitch chart. 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.
