====Slope(Pitch)====

Set one end of a 12” level on the roof surface – make it level. Take a tape measure from the other end down to the surface of the roof. This will give you the slope of the roof. For example, a roof rising 4-inches for each horizontal foot has a 4/12 slope. Slope is also sometimes referred to as "pitch".

The greater the slope, the more material will be required to complete the installation of the roof, hence the slope factor. The slope factor multiplied by the area of the roof will give you the number or sq. ft. to be covered.
