How Many Degrees Is A 1512 Roof Pitch

To convert between american roofing ratios and pitch degrees follow these steps.

How many degrees is a 1512 roof pitch.

Since a 12 12 roof pitch is 45 degrees why isn 39 t a 6 12 roof pitch half of that 22 5 degrees. If you are looking at a roof plan for your home or business very rarely will it list the roof pitch in degrees instead it lists the rise and the run of the roof. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement.

For example a 7 12 roof pitch means that for ever 12 of horizontal distance the roof will increase in height by 7. Divide the first part of the ratio by 12 to work out the pitch. With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

A 6 12 pitch is equal to 26 57 degrees. Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. 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. 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. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees.
