15 Degree Slope Roof 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.

15 degree slope roof pitch.

Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Angle the angle of a roof is the same as the roof s slope except instead of being. The triangle diagram will be re drawn to scale with all dimensions marked.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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. 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 table below shows common roof pitches and the equivalent grade degrees and radians for each.

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. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Drag sliders to animate the results and diagram. 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.

Steeper slopes increase the sail effect that makes them susceptible to wind. 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. The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. 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.

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. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. Roof pitch calculator results explained.
