Everyday math
Slope of a roof. An easy way to determine the slope of a roof is to set one end of a 12 inch level on the roof surface and hold it level. Then take a tape measure or ruler and measure from the other end of the level down to the roof surface. This will give you the slope of the roof. Builders, sometimes, refer to this as pitch and state it as an “
12 pitch” meaning
, where
is the measurement from the roof to the level—the rise. It is also sometimes stated as an “
-in-12 pitch”.
