412 Roof Pitch In Degrees
Roofing that has a 5/12 pitch angle rises by 22.62 degrees and can appear fairly flat compared to roofing with a steeper pitch.
412 roof pitch in degrees. Rise/run = rise ÷ run = slope. If a roof rises 4″ in a length of 12″, this is 4/12 roof pitch.
12 slope ratio formula used: 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.
Determine length of common rafter. Simply mark a level at 12″.
Roof pitch (slope) roof angle (degrees) slope factor (multiplier) valley and hip factor (multiplier) 1:12 pitch 4.76° 1.0035 1.4167 2:12 pitch 9.46° 1.0138 1.4240 3:12 pitch 14.04° 1.0308 1.4362 4:12 pitch 18.43° 1.0541 1.4530 5:12 pitch 22.62° 1.0833 So, if your roof rises 4 inches for every 12 inches of horizontal length, then the pitch of your roof is expressed as 4:12.
Roofs with a pitch of 4/12 are approximately 18.4 degrees, depending on how exact you'd like to be in your measurement. A 4/12 roof pitch indicates the roof rises 4 inches in height for every 12 inches, as measured horizontally from the edge of the roof to the centerline.
How to convert roof pitch in degrees you will need a scientific calculator to be able to complete this calculation. Roofing with this pitch may make a property warmer inside because there is not as much space for heat to escape, as there would be if the roofing were steeper.

Two most common methods (4/12 or 4:12) are used for marking the pitch of a roof. 4/12 roof pitch angle = 18.43 degrees.
The 4/12 pitch is a roof that rises vertically toward the peak 4 inches for every 12 inches of horizontal run. 4/12 roof pitch angle = 18.43 degrees.
