Permit Requirements in St. Louis
Know when you need a permit to ensure your project is legal and safe
General Rules
In St. Louis, building permits are typically required for any roofing project that involves structural work, changes to the roof deck, or full tear-offs and re-roofing of substantial size. The city's building code generally requires permits for work that affects the building's structure, fire safety, or weather-tightness.
Permits are often required for:
- Complete tear-off and replacement of roofing materials
- Structural repairs or modifications to roof framing
- New roof installations on additions or new construction
- Roof deck replacements or significant sheathing repairs
- Re-roofing over existing layers in some circumstances
Minor repairs that do not affect structural elements may not require a permit, but it's always best to check with the city's building division to be sure.
When Permits Are Required
Residential Roofing: Full roof replacements, structural repairs, reroofing that involves removing more than one layer of existing material, and any work that changes the roof's load-bearing capacity typically requires a permit.
Commercial Roofing: Commercial and multi-family roofing projects almost always require permits. This includes new roofs, re-roofing, structural modifications, and work on roof-mounted equipment that affects the roof assembly. Commercial projects may also require additional inspections for fire ratings and energy code compliance.
Emergency Repairs: Emergency work to prevent further damage (such as tarping after a storm) can often proceed without a permit, but a permit may be needed for the permanent repair. Check with the city if you're unsure.
Common Exemptions
Some minor roofing work may not require a permit in St. Louis. Typical exemptions include:
- Minor spot repairs to a small area of shingles or flashing (less than 100 square feet, no structural work)
- Replacing a few damaged shingles or tiles without affecting the roof deck
- Cleaning and maintenance such as gutter cleaning or moss removal
- Temporary repairs (like tarping) in emergency situations
Even if a permit is not required, all work must still meet building code standards. If you're unsure whether your project qualifies for an exemption, it's best to confirm with the local permitting authority before starting work.

Permit Process
Determine If You Need a Permit
Review your project scope against St. Louis building requirements. Contact the city's building division or visit their office to discuss your specific roofing project. It's helpful to have your project details, property address, and scope of work ready when you inquire.
Prepare Your Documents
For most roofing permits, you'll need to submit a completed permit application, a site plan showing the property, and details about the roofing work. Commercial projects may require engineered drawings or structural calculations. Having a licensed contractor handle this step can streamline the process significantly.
Submit the Application
Submit your completed application and supporting documents along with the applicable fee. Applications are typically reviewed for code compliance, zoning, and any special district requirements. Review timelines can vary depending on project complexity.
Schedule Inspections
Once your permit is issued and work begins, inspections are required at key stages. For roofing, this often includes a rough-in inspection after the deck is prepped but before new materials are installed, and a final inspection after completion. Your contractor should coordinate these inspections with the city.
Receive Certificate of Completion
After passing all required inspections, a certificate of completion or final approval is issued. This document confirms the work meets code and is important for property records, future sales, and insurance purposes. Keep it with your property records.
Compliance Tips
- ✓ Always verify permit requirements with the City of St. Louis Building Division before starting any roofing work — what seems like a minor repair may require a permit.
- ✓ Hire a licensed contractor who is familiar with St. Louis building codes and permit procedures. They can handle the permit application and coordinate inspections.
- ✓ If your property is in a historic district, contact the Cultural Resources Office early in the planning process to understand material and design requirements.
- ✓ Keep copies of all permits, inspection reports, and certificates of completion for your property records — they're important for future home sales and insurance claims.
- ✓ Don't skip the permit to save time or money. Unpermitted work can lead to costly fines, stop-work orders, and complications when selling your property.
- ✓ Schedule inspections promptly and ensure your contractor is present for all required inspection appointments to avoid delays in project completion.
Special Considerations
HOA Rules
If your property is located within a homeowners' association (HOA) in St. Louis, the HOA may have its own architectural review or approval process for roofing projects. HOAs often have specific rules about roofing materials, colors, and styles to maintain neighborhood consistency.
Obtain HOA approval before pulling a city permit or starting work. Failure to get HOA approval could result in fines or having to redo the work. Check your HOA's CC&Rs (Covenants, Conditions & Restrictions) for specific roofing requirements.
Zoning
St. Louis zoning regulations may affect your roofing project in several ways. Roof height limitations, setback requirements for roof additions or dormers, and material restrictions in certain zoning districts all come into play.
If your project involves changing the roof structure (adding dormers, raising the roof, or installing a rooftop deck), a zoning review will likely be part of the permit process. Your contractor or a zoning specialist can help determine if your project is compliant with current zoning codes.
Historic Properties
St. Louis has several historic districts, including areas within the Lafayette Square, Soulard, and Central West End neighborhoods, among others. Property in a locally designated historic district must go through additional review by the city's Preservation Board or Cultural Resources Office.
Historic district approval may be required before a building permit can be issued. This often involves a review of proposed roofing materials to ensure they are historically appropriate. Slate, tile, or specific color palettes may be required. Plan for extra time — historic review can add weeks to your project timeline.
