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.

Roof pitch calculator results explained. 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. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.

Steeper slopes increase the sail effect that makes them susceptible to wind. The minimum roof pitch for shedding snow is around 30 or a 6 12 or 7 12 slope although this is not a definite as the material of your roof the direction of the snow and wind are some factors that can affect whether or not snow will slide as roofs of as little as 10 have been reported to shed snow. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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.

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. 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. Angle the angle of a roof is the same as the roof s slope except instead of being. Lower slopes don t handle wind driven rain as well.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind.

The triangle diagram will be re drawn to scale with all dimensions marked. 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.
