Roof Pitch Vs Degrees

Directly measure roof pitch angle and calculate pitch and angle on phone or tablet.

Roof pitch vs degrees.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. What is the pitch of a 30 degree roof. To see roof pitch visual examples how to determine pitch. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees.

Set bevel gauge directly from phone or tablet screen. 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. Divide the first part of the ratio by 12 to work out the pitch. Steeper slopes increase the sail effect that makes them susceptible to wind.

The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. What degree angle is a 12 12 pitch roof. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Lower slopes don t handle wind driven rain as well.

If you want to convert from degrees to the american ratio then simply find the tangent of the angle. 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. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. 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.

8 12 pitch 33 75 degrees. Yes 7 12 a pitch of a 30 degree roof is roughly the same as a 7 12 roof pitch. Enter base length to calculate rise and diagonal for current pitch angle. 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.

What is a 3 12 roof pitch. To convert between american roofing ratios and pitch degrees follow these steps. Roof angles and rafter plumb cuts. Find the inverse tangent of the pitch to find the angle in degrees.

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. You have to pay higher cost for steeper pitch. Visit this page on your phone to directly measure pitch and angles.

The gentle slope of a 4 12 roof pitch falls on the cusp between moderate pitch and low pitch. 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. Select inches to enter decimal inches or millimeters for metric.
