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. However you can only use this pitch with built up roofing or specialized synthetic roofing.

Slope ratio a roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a 4 in 12 slope. The triangle diagram will be re drawn to scale with all dimensions marked.
