16 12 Roof Pitch Degree

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.

16 12 roof pitch degree. A ratio of 1 1 62 is known as the golden ratio and therefore the vast majority of roof pitch in degrees charts you see will be working to this ratio at the very least. 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. 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.

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. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. Angle the angle of a roof is the same as the roof s slope except instead of being. 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.

The value displayed as the rise will be your x. Lower slopes don t handle wind driven rain as well. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length.

Therefore you can feel quite comfortable in working with someone who can provide you with a roof pitch conversion chart given that they will be adhering to the. The table below shows common roof pitches and the equivalent grade degrees and radians for each. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Steeper slopes increase the sail effect that makes them susceptible to wind.

For a more detailed explanation of the roof pitch multiplier see how to find the area of a sloped roof if you know the roof pitch in degrees find the secant of the slope using a scientific calculator for example if the roof pitch is 45 then sec 45 1 414213. 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. Roof pitch calculator results explained. Pitch tan angle where angle is the roof pitch expressed in degrees.
