Roof Pitch 21 Degrees

Roof pitches ranging from 0 12 0 degrees to 21 12 60 26 degrees.

Roof pitch 21 degrees.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. 8 12 pitch 33 75 degrees. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Click here to view our roof pitch diagram chart.

Active ventilation products. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. Pitch tan angle where angle is the roof pitch expressed in degrees. High pitched roofs often need extra fasteners and their pitch can be as high as 21 12.

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. You can also calculate roof pitch even without using a roof slope calculator. 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. Use the following formula which also describes a right triangle.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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. 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.

Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof. The value displayed as the rise will be your x. 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.

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.
