63 roofing listings are recorded at Thornton, Colorado 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, Adams County is the one that comes up. Roofing permits and inspections are issued locally rather than by the state, so a re-roof in Thornton goes through Adams County or the municipality's own building department, whichever holds jurisdiction at the property.

Licensing for roofers working in Thornton
No state licence is required to roof a house in Colorado; 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 Thornton: a business licence or contractor registration where the jurisdiction requires one, plus a permit and an inspection through Adams County or the city for the work itself.
