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. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across. The combination of two numbers are used to display or show the roof pitch. The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run.

Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof. If the rise is 6 inches for every 12 inches of run then the roof slope is 6 in 12 the slope can be expressed numerically as a ratio. 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. 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.

This will give you the rise over run or pitch.
