Roof Conversions Calculator
Converts from slope to angle, grade (as a percent) and and slope after entering any one of the four.
-Slope: Slope in units of rise relative to run. If a roof rises 5 inches for each 12 inches of horizontal run, the slope of the roof is 5 to 12, written 5 : 12. This is often referred to (incorrectly) as pitch.
-Angle: Angle formed at the base and the incline of the roof.
-Grade: Percent of grade relative to 100. For example, on a 5:12 sloped roof, the rise in feet from the base to the top of the rise will be 41.67ft.
-Incline: Amount of incline relative to 100 feet.
Calculate the angle, grade and incline for a roof that has a 4 in 12 slope.
-Slope: 4 : 12
