2 degree pitch roof.

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

Pitch is the term used to describe the angle slope or slant of your roof. The triangle diagram will be re drawn to scale with all dimensions marked. 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. 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.

These roofs have a pitch less than 4 12. Or the colon can replace the slash as in 2 12 or 7 12. 8 12 pitch 33 75 degrees. You have to pay higher cost for steeper pitch.

To see roof pitch visual examples how to determine pitch. 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. Look at the column labeled pitch then look under degrees to get the corresponding amount of 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. 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. Generally such roofs have a pitch ranging from 1 2 12 to 2 12. Lower slopes don t handle wind driven rain as well.

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. 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 designations are comprised of two numbers indicating a ratio. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.

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. The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.
