15 roofing listings are recorded at O Fallon, Missouri addresses. None of them has a Google rating matched to it yet, so what follows is contact detail rather than reputation data.
County is recorded for only some of these listings; where it is, Saint Charles County is the one that comes up. Roofing permits and inspections are issued locally rather than by the state, so a re-roof in O Fallon goes through Saint Charles County or the municipality's own building department, whichever holds jurisdiction at the property.

Licensing for roofers working in O Fallon
No state licence is required to roof a house in Missouri; city or county licensing usually still applies. The state leaves the roofing specialty to local government.
In practice that makes the local layer the one that matters in O Fallon: a business licence or contractor registration where the jurisdiction requires one, plus a permit and an inspection through Saint Charles County or the city for the work itself.
