Roof Pitch 21 Degrees

Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees.

Roof pitch 21 degrees.

High pitched roofs often need extra fasteners and their pitch can be as high as 21 12. The value displayed as the rise will be your x. 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. To see roof pitch visual examples how to determine 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. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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.

Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. 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. Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof.

A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Here are the equations you may use to solve for the length of the slope and the rafter. Roof pitches ranging from 0 12 0 degrees to 21 12 60 26 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.

If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length. Pitch tan angle where angle is the roof pitch expressed in degrees. You can also calculate roof pitch even without using a roof slope calculator. Active ventilation products.
