2 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. 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. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Measurement of your house roof pitch is one of the most important things while constructing pitched roof.

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. After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Find the inverse tangent of the pitch to find the angle in degrees.

Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. Divide the first part of the ratio by 12 to work out the pitch. What degree angle is a 12 12 pitch roof. Most roof s have a pitch in the 4 12 to 9 12 range.

To see roof pitch visual examples how to determine 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. A 12 12 pitch roof has a pitch angle of 45. 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.

You have to pay higher cost for steeper pitch. 8 12 pitch 33 75 degrees.
