2 Degree Roof Pitch

Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree.

2 degree roof pitch. Pitch is the term used to describe the angle slope or slant of your roof. 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 following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. A 12 12 pitch roof has a pitch angle of 45.

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. 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. Most roof s have a pitch in the 4 12 to 9 12 range.

Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. To find the slope or fall of a ball or other object that is at an angle of 2 degrees for over 3 9 minutes you. 7 degrees is 1 1 2 rise in one foot. 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.

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. 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. To convert between american roofing ratios and pitch degrees follow these steps.

Lower slopes don t handle wind driven rain as well. What degree angle is a 12 12 pitch roof. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. 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. Find the inverse tangent of the pitch to find the angle in degrees. Divide the first part of the ratio by 12 to work out the pitch. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

The triangle diagram will be re drawn to scale with all dimensions marked. How much fall in a 2 degree foor over 3 9 mts. Steeper slopes increase the sail effect that makes them susceptible to wind.
