2 Degree Pitch Roof

Steeper slopes increase the sail effect that makes them susceptible to wind.

2 degree pitch roof.

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. 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.

You have to pay higher cost for steeper pitch. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.

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. Generally such roofs have a pitch ranging from 1 2 12 to 2 12. 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.

These roofs have a pitch less than 4 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. The value displayed as the rise will be your x. Drag sliders to animate the results and diagram.

The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. Roof pitch defined and explained. 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. 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.

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

Pitch tan angle where angle is the roof pitch expressed in degrees. 8 12 pitch 33 75 degrees. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
