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 table below shows common roof pitches and the equivalent grade degrees and radians for each. Angle the angle of a roof is the same as the roof s slope except instead of being. 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.

Roof pitch calculator results explained. Steeper slopes increase the sail effect that makes them susceptible to wind. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. 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. 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. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. 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. 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. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. Lower slopes don t handle wind driven rain as well.
