How Many Degrees Is A 1512 Roof Pitch

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

How many degrees is a 1512 roof pitch. 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 12 12 pitch roof has a pitch angle of 45. Since a 12 12 roof pitch is 45 degrees why isn 39 t a 6 12 roof pitch half of that 22 5 degrees. Divide the first part of the ratio by 12 to work out the 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. Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof. 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.

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. To see roof pitch visual examples how to determine 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. 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 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 following diagram will let you easily convert roof pitch. To convert between american roofing ratios and pitch degrees follow these steps. 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.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. A 6 12 pitch is equal to 26 57 degrees. The table below shows common roof pitches and the equivalent grade degrees and radians for each. For example a 7 12 roof pitch means that for ever 12 of horizontal distance the roof will increase in height by 7.

Find the inverse tangent of the pitch to find the angle in degrees. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.
