Registration details
  • license: Montrose Code of Ordinances § 4-1-4, read in full, licenses only a "Gas fitter's license" (4-1-4(A)) and a "Plumber's license" (4-1-4(B)) — no roofing- or general-contractor license. Title V - Business Regulations, Chapter 5-1 (Licenses), read in full, covers only "Carnivals" (§ 5-1-1) and "Handbills" (§ 5-1-2); the City's Code of Ordinances contains no general business-license chapter that would reach a roofing contractor. This confirms the existing description note that the Building Services page "does not list a city license requirement specific to roofing contractors."
