How Many Degrees Is A 1512 Roof Pitch

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.

How many degrees is a 1512 roof pitch.

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. On my roof chart and construction calculator a 5 12 roof pitch is 22 5 degrees. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Divide the first part of the ratio by 12 to work out the pitch.

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. For example a 7 12 roof pitch means that for ever 12 of horizontal distance the roof will increase in height by 7. A 6 12 pitch is equal to 26 57 degrees. 8 12 pitch 33 75 degrees.

A 12 12 pitch roof has a pitch angle of 45. Find the inverse tangent of the pitch to find the angle in degrees. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. To see roof pitch visual examples how to determine pitch.

The following diagram will let you easily convert roof pitch. 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. 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.

After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. 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 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.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. 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.
