2 Degree Roof Pitch

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

2 degree roof pitch.

You have to pay higher cost for steeper 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. 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. Measurement of your house roof pitch is one of the most important things while constructing pitched roof.

Roof pitch designations are comprised of two numbers indicating a ratio. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. The triangle diagram will be re drawn to scale with all dimensions marked. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 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. Drag sliders to animate the results and diagram. Or the colon can replace the slash as in 2 12 or 7 12. A 12 12 pitch roof has a pitch angle of 45.

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. Roof pitch defined and explained. To see roof pitch visual examples how to determine pitch. 8 12 pitch 33 75 degrees.

Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. Pitch is the term used to describe the angle slope or slant of your roof. 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. Most roof s have a pitch in the 4 12 to 9 12 range.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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. How much fall in a 2 degree foor over 3 9 mts.

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 table below shows common roof pitches and the equivalent grade degrees and radians for each. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Find the inverse tangent of the pitch to find the angle in degrees.
