25 Degree Roof Slope

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

25 degree roof slope. Find the tangent of the degree value. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. Divide the first part of the ratio by 12 to work out the pitch. Find the inverse tangent of the pitch to find the angle in degrees.

But with the use of a roof pitch in degrees converter you will be able to get the correct 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. An example for a steep sloped roof is 8 12.

The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches. This means that the rise of the slope goes up or down 8 inches for every 12 inches. 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. 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.

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. Multiply the tangent by the run which is 12 since we re doing this in. Find the tangent of the degree value. 3 8 in 12 slope 3 125 slope.

Some sources consider low slope to include 3 12 pitch roofs. 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. Low slope roofs are from 0 to 3 12 in pitch. 0 4663 x 100 46 63.

What degree angle is a 12 12 pitch roof. For a slope of 25 tan 25 0 4663. A 12 12 pitch roof has a pitch angle of 45. Notes to the table above.

Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. To put it in perspective the angle of this slope would be around 30 degrees. 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.
