WebFirst, measure 12 inches on a level and make a mark. Place one end of the level against the roof. Hold the end of the tape measure against the roof, extending it so it’s perpendicular to your level. Move the tape measure along the roof and stop when it meets the level at the 12-inch marker. This vertical distance is your roof’s pitch. WebTake a roof where the rise is three feet and the run is nine-and-a-half feet. The rise converts to 36 inches, while the run converts to 114 inches. Divide 36 by 114, and the resulting figure is 31.58 percent. Multiply this number by 12, and the result is 3.79 inches. In this scenario, the run-rise ratio for your roof pitch is 3.79:12.
