The roof pitch conversion factor is a number that when multiplied by the area covered by the roof gives an estimate the total surface area of the sloped roof itself. This will give you the rise over run or pitch.

Flat and nearly flat roofs a pitch of 1 in 12 or 2 in 12 cannot be covered with shingles or shakes of any material since there is not enough angle to combat the danger of blow off. This numerical figure is significant as not everybody can understand the technical measurements. 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 means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

The roof pitch would be described as a 6 12 pitch. For roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1.
