Missouri Roofing Contractor Licenses are valid for two years from the date of issuance. Renewal must occur before the expiration date shown on your license, with deadlines typically falling in even-numbered years.

Approved continuing education providers are listed on the Division website.

If you miss the renewal deadline, your license becomes inactive, and you cannot legally perform roofing work until it is renewed. Reinstatement of an expired license requires a reinstatement fee (approximately $100–$150 additional) and proof of continuing education completion. During the grace period (typically 30 days after expiration), you may continue working while your renewal is pending, but you should carry proof of application submission. Online renewal typically processes within 1–2 weeks, while mail applications may take 3–4 weeks.

Operating as a roofing contractor in Missouri without a valid license violates Missouri Revised Statutes § 329.020 and subjects you to civil and criminal penalties. The primary civil penalty is a fine of up to $500 for each violation, with each day of unlicensed operation constituting a separate violation—potentially resulting in cumulative fines of thousands of dollars.

Criminal penalties under § 329.020 include misdemeanor charges punishable by fine of up to $500 and/or imprisonment for up to 30 days. The Division of Professional Registration can issue a Cease and Desist Order, immediately prohibiting you from performing any roofing work and requiring you to notify current clients of your unlicensed status.

Unlicensed roofing operations are discovered through customer complaints filed with the Division, city inspector reports during permit reviews, or routine enforcement investigations. If a customer reports you for unlicensed work, the Division initiates an investigation that may result in formal complaints and hearings. Additionally, general liability and workers' compensation insurance policies may be voided if claims involve unlicensed work, leaving you personally liable for all damages and injuries. St Louis city can levy additional fines of $100–$500 for performing work without local permits under St Louis City Code § 26.86, regardless of state license status.
