2 degree roof pitch.

Pitch is the term used to describe the angle slope or slant of your roof. 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 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.

Measurement of your house roof pitch is one of the most important things while constructing pitched 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. To convert between american roofing ratios and pitch degrees follow these steps. A 12 12 pitch roof has a pitch angle of 45.

8 12 pitch 33 75 degrees. Look at the column labeled pitch then look under degrees to get the corresponding amount of degrees. Most roof s have a pitch in the 4 12 to 9 12 range. Divide the first part of the ratio by 12 to work out the 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. Drag sliders to animate the results and diagram. 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.

You have to pay higher cost for steeper pitch. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.

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. What degree angle is a 12 12 pitch roof. Find the inverse tangent of the pitch to find the angle in degrees. 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.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. 7 degrees is 1 1 2 rise in one foot. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. 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.
