A roof that rises 8 feet over a 24-foot span was said to have a “1 to 3” pitch. If the rise is 4 feet over a 24-foot span, then the roof pitch was said to be “1 to 6.” The pitch can be expressed numerically as a fraction. The pitch fraction represents a certain amount of vertical rise over the entire span.

First, measure 12 inches from one end of the level and make a mark. Then, in the attic, place the end of the level against the bottom of a roof rafter and hold it perfectly level. Now measure vertically from the 12-inch mark on the level straight up to the underside of the rafter, as illustrated.
