To convert a roof slope expressed as “X-in-12″ to a roof slope expressed in degrees, find the arctangent of (rise/run). Divide the rise (that’s the “X”, yours will vary) by the run (always 12). Using a scientific calculator, find the arctangent of the result.
WebThe roof pitch is the slope of the rafter. The pitchis commonly defined as the ratio of rise over run in the form of x/12. The rise is the height of the roof, and the runis the horizontal span (as pictured above). For example, if a roof has a pitch of 4/12, then for every 12 inches the building extends horizontally, it rises 4 inches. WebMar 25, 2024 · The traditional method of measuring roof pitch is to display it as a ratio of X:12. This is done by measuring the number of inches a roof rises vertically for every 12 …
