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.
Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
Find the inverse tangent of the pitch to find the angle in degrees.
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.
What degree angle is a 12 12 pitch roof.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
The triangle diagram will be re drawn to scale with all dimensions marked.
Divide the first part of the ratio by 12 to work out the pitch.
To convert between american roofing ratios and pitch degrees follow these steps.
A 12 12 pitch roof has a pitch angle of 45.
45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
Enter any pitch or fraction of pitch to find angle.
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.
Drag sliders to animate the results and diagram.
Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or 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.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
Common roof pitches and equivalent grade degree and radian angles.
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.
While measuring tap to hear the spoken angle continuously as it changes.
Visit this page on your phone to directly measure pitch and angles.
Enter any angle or fraction of angle to find pitch.
Most roof s have a pitch in the 4 12 to 9 12 range.
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 means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
