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.
14 degrees roof slope.
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.
The table below shows common roof pitches and the equivalent grade degrees and radians for each.
45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as.
Roof pitch calculator results explained.
S grade 1 m 2 m 50 slope and roof pitch.
Angle the angle of a roof is the same as the roof s slope except instead of being.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
Enter any angle or fraction of angle to find pitch.
Find the inverse tangent of the pitch to find the angle in degrees.
A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.
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.
Lower slopes don t handle wind driven rain as well.
A 12 12 pitch roof has a pitch angle of 45.
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.
Roof pitch visual examples.
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.
Steeper slopes increase the sail effect that makes them susceptible to wind.
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.
Enter any pitch or fraction of pitch to find angle.
What degree angle is a 12 12 pitch roof.
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.
Roof pitch on the form x 12 can be expressed in grades as.
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.
