15 Degree Slope Roof Pitch

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.

15 degree slope roof pitch.

The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Drag sliders to animate the results and diagram. 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.

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. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. The table below shows common roof pitches and the equivalent grade degrees and radians for each. Roof pitch calculator results explained.

A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. 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. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. 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. Lower slopes don t handle wind driven rain as well. The triangle diagram will be re drawn to scale with all dimensions marked.

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. 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. 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.
