2 Degree Pitch Roof

Measurement of your house roof pitch is one of the most important things while constructing pitched roof.

2 degree pitch roof. To see roof pitch visual examples how to determine pitch. The triangle diagram will be re drawn to scale with all dimensions marked. Drag sliders to animate the results and diagram. Lower slopes don t handle wind driven rain as well.

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. Roof pitch defined and explained. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks.

Pitch tan angle where angle is the roof pitch expressed in degrees. 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. Generally such roofs have a pitch ranging from 1 2 12 to 2 12. These roofs have a pitch less than 4 12.

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. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. Or the colon can replace the slash as in 2 12 or 7 12.

Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. Roof pitch designations are comprised of two numbers indicating a ratio. 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. Pitch is the term used to describe the angle slope or slant of your roof.

A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. 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. 8 12 pitch 33 75 degrees. You have to pay higher cost for steeper pitch.

The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. The table below shows common roof pitches and the equivalent grade degrees and radians for each. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
