30 Degree Angle Roof Pitch

For a pitch expressed in inches per foot convert to a fraction.

30 degree angle roof pitch. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Steeper slopes increase the sail effect that makes them susceptible to wind. 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 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.

First convert the pitch to a slope. 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. If you want to convert from degrees to the american ratio then simply find the tangent of the angle. 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. Enter any pitch or fraction of pitch to find angle. To convert between american roofing ratios and pitch degrees follow these steps. A 12 12 pitch roof has a pitch angle of 45.

To do this simply convert the rise and run as a fraction to a decimal form eg. Lower slopes don t handle wind driven rain as well. What is a 3 12 roof pitch. 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.

Find the inverse tangent of the pitch to find the angle in degrees. 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. A 7 12 pitch equals 30 26 degrees. 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.

Rise run rise run slope. 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. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. Divide the first part of the ratio by 12 to work out the pitch.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Yes 7 12 a pitch of a 30 degree roof is roughly the same as a 7 12 roof pitch.
