The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.
Pitch of roof in degrees.
Roof slope calculator example of use.
A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.
Lower slopes don t handle wind driven rain as well.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
Pitch tan angle where angle is the roof pitch expressed in degrees.
Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees.
To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the 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.
It always makes sense to the standard roof pitch angle spot on as the benefits of doing so are quite obvious.
Steeper slopes increase the sail effect that makes them susceptible to wind.
To see roof pitch visual examples.
Roof pitch and corresponding angles.

If you want to know how to find the pitch of a roof then start with a calculator.
8 12 pitch 33 75 degrees.
Pitch tan angle use this when you express the angle of the roof pitch in degrees what is the standard pitch of a roof.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
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.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
To do this simply convert the rise and run as a fraction to a decimal form eg.
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.
First convert the pitch to a slope.
With the help of these roof pitch degree calculator programs you can make sure that your home is nice and balanced.
This drawing demonstrates how many degrees rise for each pitch of a typical roof.
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.
