Not scored yet

Roofer

This occupation is not in the launch set. The set is twenty, chosen to cover the range of the scale rather than the range of the workforce, so most jobs are not here yet.

The nearest occupation that is scored is Plumber. Physical work at height on structures that are never standard.

How this match was made By hand, not by arithmetic. Roofer has no declared inputs on this site, so there is nothing to compute a distance from — and inventing four numbers for it, purely to make the comparison look calculated, is exactly what the method is supposed to refuse. Treat it as a signpost, not a score.
