What the tool does, how to run it, and what to expect from the result.
Pitch is the rise in inches for every 12 inches of horizontal run. A 6/12 roof rises 6 in per foot: angle = arctan(6 ÷ 12) = 26.57°, slope 50%. The multiplier √(1 + (rise/run)²) = 1.118 converts a footprint area or run into actual roof area or rafter length.

Short answers for the questions people usually have before trying a utility like this.
4/12 to 9/12 on most houses. Below 2/12 counts as a low-slope roof and needs membrane roofing.
Hold a level horizontally against the roof, mark 12 in along it, and measure straight down to the roof surface.
