2 Degree Pitch Roof

These roofs have a pitch less than 4 12.

2 degree pitch roof.

A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. You have to pay higher cost for steeper pitch. Drag sliders to animate the results and diagram.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. 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. Look at the column labeled pitch then look under degrees to get the corresponding amount of 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.

Measurement of your house roof pitch is one of the most important things while constructing pitched roof. Roof pitch defined and explained. Generally such roofs have a pitch ranging from 1 2 12 to 2 12. The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily.

To see roof pitch visual examples how to determine pitch. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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.

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. Or the colon can replace the slash as in 2 12 or 7 12. 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. The value displayed as the rise will be your x.

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. The triangle diagram will be re drawn to scale with all dimensions marked. Pitch tan angle where angle is the roof pitch expressed in degrees. Steeper slopes increase the sail effect that makes them susceptible to wind.

Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks. Lower slopes don t handle wind driven rain as well. 8 12 pitch 33 75 degrees.
