Roof Degrees To Slope

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

Roof degrees to slope. Visit this page on your phone to directly measure pitch and angles. Roof pitch is the slope created by the rafter. Select inches to enter decimal inches or millimeters for metric. Roof pitch on the form x 12 can be expressed in grades as.

For example in construction you may refer to the pitch of a roof or the grade of a slab. Directly measure roof pitch angle and calculate pitch and angle on phone or tablet. Set bevel gauge directly from phone or tablet screen. Many different professions use slope in describing an angle.

Pitch tan angle where angle is the roof pitch expressed in degrees. 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. 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.

Example slope as grade. Lower slopes don t handle wind driven rain as well. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. Sometimes slope is referred to as pitch angle rise incline or grade.

You can find the roof pitch in the form of x 12 like 4 12 or 9 12. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. 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. Both are referring to angles.

The value displayed as the rise will be your x. Degrees tan 1 43 calculated out this gives an angle of 23 27 degrees. S grade 1 m 2 m 50 slope and roof pitch. The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.

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. Enter base length to calculate rise and diagonal for current pitch angle. Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as. 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.

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