You can also calculate roof pitch even without using a roof slope calculator.
10 12 roof pitch degrees.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
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.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
Enter any angle or fraction of angle to find 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.
Roof pitch degree table.
Roof angles and rafter plumb cuts.
Most roof s have a pitch in the 4 12 to 9 12 range.
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.
Divide the first part of the ratio by 12 to work out the pitch.
High pitched roofs often need extra fasteners and their pitch can be as high as 21 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 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.
Enter base length to calculate rise and diagonal for current pitch angle.
Directly measure roof pitch angle and calculate pitch and angle on phone or tablet.
These roofs have a pitch less than 4 12.
A 12 12 pitch roof has a pitch angle of 45.
A 12 in 12 pitch is a steep 45 degree angle roof.
Visit this page on your phone to directly measure pitch and angles.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
If a roof rises 10 in a length of 12 this is 10 12 roof pitch.
Find the inverse tangent of the pitch to find the angle in degrees.
10 12 roof pitch angle 39 81 degrees.
To convert between american roofing ratios and pitch degrees follow these steps.
See the image below for more explanation on rise run and pitch.
Select inches to enter decimal inches or millimeters for metric.
Set bevel gauge directly from phone or tablet screen.
Conventional roofs are the easiest to construct and you can walk on them safely.
Enter any pitch or fraction of pitch to find angle.
