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.

A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. Enter base length to calculate rise and diagonal for current pitch angle. Pitch tan angle where angle is the roof pitch expressed in degrees. Steeper slopes increase the sail effect that makes them susceptible to wind.

Sometimes slope is referred to as pitch angle rise incline or grade. Lower slopes don t handle wind driven rain as well. 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. 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.

Select inches to enter decimal inches or millimeters for metric. 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. Both are referring to angles. Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as.

Roof angles and rafter plumb cuts. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Roof pitch is the slope created by the rafter. 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.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. For example in construction you may refer to the pitch of a roof or the grade of a slab. 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. Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.

Example slope as grade. Many different professions use slope in describing an angle. You can find the roof pitch in the form of x 12 like 4 12 or 9 12. Visit this page on your phone to directly measure pitch and angles.

Roof pitch on the form x 12 can be expressed in grades as. Set bevel gauge directly from phone or tablet screen. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.

S grade 1 m 2 m 50 slope and roof pitch. Degrees tan 1 43 calculated out this gives an angle of 23 27 degrees.
