Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

How do you measure pitch on a roof. Placing a ladder near the roof you will put a level a foot or so up on the roof hold it level and measure from the 12 inch mark straight down.
