How Many Degrees Is A 1512 Roof Pitch

Find the inverse tangent of the pitch to find the angle in degrees.

How many degrees is a 1512 roof pitch.

After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. A 12 12 pitch roof has a pitch angle of 45. On my roof chart and construction calculator a 5 12 roof pitch is 22 5 degrees. 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.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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. 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. 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.

Divide the first part of the ratio by 12 to work out the pitch. Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof. The table below shows common roof pitches and the equivalent grade degrees and radians for each. The roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need.

For example a 7 12 roof pitch means that for ever 12 of horizontal distance the roof will increase in height by 7. The following diagram will let you easily convert roof pitch. To convert between american roofing ratios and pitch degrees follow these steps. To see roof pitch visual examples how to determine pitch.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Since a 12 12 roof pitch is 45 degrees why isn 39 t a 6 12 roof pitch half of that 22 5 degrees. 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. A 6 12 pitch is equal to 26 57 degrees.

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