The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages. Degrees atan slope. Conventional roofs are the easiest to construct and you can walk on them safely. This forms an angle of 18 5 between the horizontal section and the roof and creates a gentle incline that is seen as a midpoint between a low pitch and medium pitch roof.

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. The combination of two numbers are used to display or show the roof pitch. What roof angle in degrees. The pros and cons of aluminum roofing.

For a pitch expressed in inches per foot convert to a fraction first eg. Also see our page quick reference. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

Enter any pitch or fraction of pitch to find angle. Let s find the angle in degrees for a roof with a 4 in 12 pitch. 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. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.

You can also calculate roof pitch even without using a roof slope calculator. Select the best roof trusses and budget amount. Next find the degrees by finding the arc tangent of the slope eg. 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.

Degrees to roof pitch rise in run to see a table. A 4 in 12 pitch becomes 4 12 then divide. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across. They have a pitch ranging from 4 12 to 9 12.
