Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
14 degrees roof slope.
Divide the first part of the ratio by 12 to work out the pitch.
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.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
Enter any angle or fraction of angle to find pitch.
Roof pitch is the slope created by the rafter.
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.

Lower slopes don t handle wind driven rain as well.
The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.
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.
Find the inverse tangent of the pitch to find the angle in degrees.
Roof pitch calculator results explained.
Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as.
Roof pitch on the form x 12 can be expressed in grades as.
Steeper slopes increase the sail effect that makes them susceptible to wind.
Roof pitch visual examples.
Roof pitch to degrees equivalents this drawing demonstrates how many degrees rise for each pitch of a typical roof.
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.
You can find the roof pitch in the form of x 12 like 4 12 or 9 12.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
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.
Angle the angle of a roof is the same as the roof s slope except instead of being.
45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
What degree angle is a 12 12 pitch roof.
A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.
Example slope as grade.
S grade 1 m 2 m 50 slope and roof pitch.
To convert between american roofing ratios and pitch degrees follow these steps.
