Roofing/ general contractors are not among these exemptions, so a roofing contractor doing business in St. Peters is subject to the general business license requirement. This is a general business license, NOT a roofing- or construction-trade-specific license. Section 605.007(B) additionally requires "proof of a certificate of insurance for workers' compensation coverage if said applicant for license is required to cover his or her liability under Chapter 287.061, RSMo." as a condition of issuance. Fee schedule (Section 605.013): "General business (605.030) $50" per year. NOTE: separate county/state trade-license requirements apply specifically to mechanical, electrical, plumbing, and drainlaying contractors (via St. Charles County or State of Missouri, per city-code cross-references found in web search of the Mechanical/Electrical/Plumbing code chapters) -- roofing/general contractors are not named among those specifically trade-licensed categories; only the general business license was confirmed to apply.
