I can confirm that the Roofmaker dialogs only allow entry in inches in the USA version. The foot symbol (') is ignored as is all other FFI abbreviations, e.g., 2-4 for 2'-4".
I'm not sure if this is a big or feature request, but am reasonably sure it will be way down on the priority list. Roofmaker hasn't really been updated in years (15 or 20 years?) and I'd be surprised if we saw a major overhaul. It inserts rafter (etc) objects, rather than beams, limiting it's use to dimensional wood (not even engineered wood/i-joist) construction. Data entry in inches is the least of its limitations.
