Let s find the angle in degrees for a roof with a 4 in 12 pitch. 4 on 12 roof pitch 4 12 roof pitch 4 12 roof slope measure roof pitch roof pitch example. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. The combination of two numbers are used to display or show the roof pitch.

It s just a little math. 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. For a pitch expressed in inches per foot convert to a fraction first eg. The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages.

For this you can take help from roof pitch factor chart. 4 12 4 12 333. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. How to convert roof pitch in degrees converting this mathematical formula is not that easy especially if you don t have a lot of skill when it comes to math.

Conventional roofs are the easiest to construct and you can walk on them safely. Degrees atan slope. 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. What roof angle in degrees.

See below after the table for directions on how to convert any roof slope from one form to another even roof slopes not shown in the table. They have a pitch ranging from 4 12 to 9 12. Enter any pitch or fraction of pitch to find angle.

Next find the degrees by finding the arc tangent of the slope eg. Enter any angle or fraction of angle to find pitch. Low slope roofing needs special techniques and materials in order to avoid leaks and roof damage and it ranges from 1 12 4 12. A 4 in 12 pitch becomes 4 12 then divide.

Select the best roof trusses and budget amount. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. High pitched roofs often need extra fasteners and their pitch can be as high as 21 12. 4 12 roof pitch to angle 18 43 degrees equivalents.

You can also calculate roof pitch even without using a roof slope calculator. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across. These roofs have a pitch less than 4 12. The pros and cons of aluminum roofing.
