What happens if you skip the permit (and you needed one)
- Stop-work order issued by University City building inspector: $250–$500 fine, plus you must pull the permit retroactively and pay double the permit fee (typically $150–$400 more).
- Insurance claim denial if roof damage occurs post-unpermitted work — most homeowners policies exclude coverage for unpermitted structural repairs, leaving you liable for 100% of weather damage.
- Resale disclosure hit: University City title company will flag unpermitted roof work on a Seller's Disclosure form, killing buyer financing or forcing a steep discount (5–10% of home value typical).
- Lender refinance block: if you ever refinance, appraisal will reveal the unpermitted work and lender will freeze the loan until you retrofit-permit the roof, which costs 50–100% more than the original permit fee.
University City roof replacement permits — the key details
IRC R907.4 is the core rule that governs University City's roof replacement enforcement: if more than two layers of roof covering already exist on the deck, you must tear off all layers down to the substrate before applying new material. University City building inspectors conduct a field inspection (often pre-permit or during the deck-nail phase) to verify layer count, and if a third layer is detected during work, the permit is flagged for violation and a stop-work order may follow. This rule exists because multiple layers add weight the original framing may not have been designed for, and they trap moisture that accelerates rot. In practice, most pre-1990 homes in University City (particularly those built in the Delmar Boulevard or South Kirkwood neighborhoods) have only one or two layers, so a straightforward tear-off proceeds without complication. However, if you discover three or more layers during the inspection, budget an additional $500–$1,500 for the extra labor and disposal cost of full tear-off.
Underlayment specification is where most homeowners and contractors trip up in University City. IRC R905.2.7 and the local inspection protocol require that when you specify your roofing material and fastening pattern on the permit application, you must also declare the underlayment type (felt, synthetic, or ice-and-water shield). For climate zone 4A, the standard is 36-pound felt or equivalent synthetic; however, ice-and-water shield (a sticky, self-adhering barrier) is strongly recommended and often required in the eave zone (extending 24 inches up from the drip edge) to manage ice dams in winter. University City winters are moderate (average 30 inches frost depth), but ice damming is common in years with freeze-thaw cycles, and building officials will ask to see the ice-and-water shield specification on your permit drawings or product sheets. If you don't call this out, the inspector may ask you to install it retroactively before final sign-off, delaying your completion by a week. The cost difference is minimal ($0.10–$0.15/square foot more), so include it upfront.
Material changes — moving from asphalt shingles to metal, tile, or slate — require structural evaluation and full plan review, not OTC processing. University City's building department sends these to the reviewing engineer because roof load changes, fastening patterns differ, and deck adequacy must be verified. A typical structural review adds 10–14 days and costs an extra $100–$200 in permit fees. If you're considering a metal roof (common in Kirkwood and adjacent neighborhoods for longevity and energy savings), expect to provide roof deck drawings, fastening schedules, and often a structural calculation from the manufacturer or a PE. Tile and slate are less common and almost always require professional structural review due to their weight (15–20 pounds per square foot vs. 2–3 for asphalt shingles). Own-your-home owner-builders can file these permits themselves, but most will hire a contractor because the plan review process is technical.
University City's permit-pull process differs slightly from neighboring Clayton or Webster Groves: the city allows OTC same-day issuance for like-for-like asphalt shingle replacements (no material change, no deck repair) if the application is complete and the property has no violation history. For material changes or anything involving structural work, you must wait for plan review, which typically takes 5–7 business days. The city's online portal (check University City's main website for the link) allows PDF upload of your roofing specifications, but many contractors still hand-deliver permits to city hall (4 Hunter Avenue, University City, MO 63130) to accelerate processing. Phone the Building Department at the main University City city hall line to confirm current hours and fax/upload procedures, as COVID-era staffing sometimes affects same-day service.
Inspections are two-phase for full roof replacement: deck inspection (after tear-off and before new underlayment is laid) and final inspection (after shingles and flashing are complete). The deck inspection verifies that nailing is correct, no structural defects are found, and the deck is clean and dry. Some inspectors in University City also verify ice-and-water shield placement at this stage. Final inspection checks that shingles are properly installed per manufacturer spec, flashing is sealed, gutters are clear, and no shortcuts were taken. Most re-roofs pass final with no issues; the deck inspection is where problems surface if the roof deck has hidden rot or the contractor did not plan for it. Budget 2–3 days between deck and final inspection for the contractor to complete work and schedule the inspection back-to-back to minimize timeline impact.
Three University City roof replacement scenarios
Climate zone 4A, frost depth 30 inches, and ice-dam prevention in University City roofs
University City sits in IECC climate zone 4A with a 30-inch frost depth, which means winter temperatures regularly drop below freezing for extended periods. This matters for roofing because freeze-thaw cycles cause ice damming — water from melting snow refreezes at the eave edge, backing up under shingles and leaking into the soffit and interior walls. IRC R905.2.7.1 (and University City's local adoption) requires that ice-and-water shield extend a minimum of 24 inches up from the eave line in cold climates. However, many homeowners and contractors view this as optional, and the building department only checks if it's specifically called out on the permit application.
The practical implication: when you fill out your roof permit application, declare that you will install ice-and-water shield in the eave zone (24 inches up, plus over any roof valleys). This costs $0.10–$0.15 per square foot more than felt underlayment (roughly $100–$150 more on a 1,600 sq ft roof), but it prevents costly water damage claims and ensures you pass final inspection without comment. If you skip it and the inspector notes it's missing, you'll be asked to retrofit it before final approval — a hassle that delays your timeline by a week. University City inspectors are consistent about this rule, particularly on properties with a history of ice-dam complaints in the building file.
A second climate consideration is loess soil (silt loam) and seasonal settling in some University City neighborhoods, particularly south of Delmar Boulevard near the karst zone. This doesn't directly affect roofing, but if your home is on a sloped lot or in a sinkhole-prone area, the structural engineer reviewing your permit may ask for deck stability confirmation before approving a material change (e.g., metal roof weight). This is rare but can delay plan review by a few days if the engineer wants additional documentation from a structural engineer or geotechnical expert.
University City's owner-builder permitting and contractor licensing rules for re-roofs
University City allows owner-builders to pull permits for work on owner-occupied single-family homes, including roof replacement. However, the building department requires either (a) a City-of-University-City-licensed roofing contractor, or (b) an affidavit signed by the owner stating that the work will be performed by the owner or immediate family members and that the owner assumes liability. Most homeowners opt for a licensed contractor because roofing is high-skill and high-risk (falls, improper fastening, underlayment mistakes), so insurance and warranty issues favor a professional. If you do hire a contractor, confirm they hold a current City of University City roofing license (not just a Missouri state license or a license from a neighboring city) — requirements vary slightly by municipality, and some contractors hold licenses in Clayton or Webster but not in University City, which can slow permit issuance if there's a licensing mismatch.
The contractor-pull process is simpler than owner-builder: the contractor calls the Building Department, provides their license number, and the permit is issued (OTC for like-for-like work). If you're pulling the permit yourself as owner-builder, you'll need to complete the application form, check the 'owner-builder' box, and attach either your ID or an affidavit. The affidavit route adds a step, so bring it to City Hall (4 Hunter Avenue, University City, MO 63130) in person or check the portal for upload instructions. Either way, OTC approval is typical for standard asphalt shingle re-roofs, but be prepared for the inspector to ask clarifying questions if you've never pulled a permit before.
Cost difference: contractor-pulled permits are usually baked into the contractor's invoice (they add a small markup), whereas owner-builder permits you pay direct to the city ($120–$200). Contractor licensing in University City is verified against a city-maintained database, so if there's any lapse, the permit may be flagged. Always ask your contractor for proof of current license before work starts, and verify it with the Building Department — it takes 2 minutes and saves headaches.

Common questions
Do I need a permit to repair a few missing shingles or patch a small leak?
Repairs under 25% of roof area using the same material are exempt from permitting in University City. A few missing shingles or a small patch falls well below this threshold. However, if you discover hidden water damage or rot in the deck while making the repair, you'll need to file a permit for the structural repair. Some homeowners pull a low-cost 'repair permit' ($50–$75) upfront to cover this contingency. If the patch is visible from the street and looks weathered, consider the permit to avoid a neighbor complaint that triggers enforcement.
I have three layers of roofing. Does that mean I'm required to tear all of them off?
Yes. IRC R907.4, which University City adopts, prohibits overlaying a third layer of roof covering. If three or more layers are present, all layers must be torn off to the substrate before new material is applied. This rule exists because multiple layers trap moisture and add weight the original framing may not support. The Building Department typically inspects during tear-off to confirm compliance. If three layers are discovered mid-work, your permit must be amended and the cost of full tear-off and disposal will increase by $500–$1,500.
What is ice-and-water shield, and is it required in University City?
Ice-and-water shield is a sticky, self-adhering underlayment that prevents water backing up under shingles in freezing conditions. It's not strictly required, but IRC R905.2.7.1 (adopted by University City) recommends it for climate zone 4A, and inspectors will ask about it if it's called out on the permit. The cost is minimal ($100–$150 more on a 1,600 sq ft roof), and it prevents ice-dam water damage in harsh winters. Include it in your permit application to avoid retrofit requests before final inspection.
If I change from asphalt shingles to a metal roof, does the permit process change?
Yes. Material changes trigger plan review (10–14 days) rather than over-the-counter approval. The city's engineer will review the metal roof fastening schedule and verify that the roof deck can support the material. Metal is heavier and requires different fastening than asphalt, so the manufacturer's technical data and nailing schedule must be provided. Permit fees are higher ($250–$400) and the timeline extends to 4–6 weeks total. University City is familiar with metal re-roofs and approves them readily if specs are complete.
What happens during the deck inspection?
The deck inspection occurs after tear-off and before new underlayment is laid. The inspector verifies that the wood decking is sound (no rot), that nailing holes are properly spaced if using new fasteners, and that the deck is clean and dry. If rot or structural damage is found, the inspector may require structural repair (a separate permit). For a straightforward tear-off with no hidden defects, the deck inspection is a quick pass. Budget 2–3 days after tear-off for this inspection, then another 2–3 days for the contractor to complete the roofing and schedule final inspection.
How much does a roof replacement permit cost in University City?
Permit fees for standard asphalt shingle re-roofs (OTC, like-for-like) run $120–$200, typically calculated at $0.08–$0.12 per square foot of roof area. Material-change permits (shingles to metal or tile) cost $250–$400 due to plan review. These fees do not include contractor labor or materials; contractor costs for a full tear-off and re-roof run $4,500–$7,500 for a 1,600 sq ft roof using standard asphalt, or $8,000–$12,000 with metal. Call the Building Department to confirm the current fee schedule.
How long does it take to get a roof replacement permit in University City?
Like-for-like asphalt shingle re-roofs are issued same-day (OTC processing, no plan review). Material changes and any work requiring structural review take 10–14 days. Once the permit is in hand, the actual roof work takes 3–5 days for tear-off and installation, with two inspections (deck and final) scheduled between them. Total timeline from permit pull to final inspection sign-off: 2–3 weeks for standard work, 4–6 weeks if plan review is needed.
What if the building inspector finds that my roof deck is rotted?
If rot is discovered during the deck inspection, you will need to file a separate structural repair permit and allow the contractor to replace the rotted decking (typically Douglas fir or similar softwood rated for outdoor use). This repair must be inspected before the roofing underlayment is installed. Costs for deck repair vary widely ($500–$3,000+) depending on the extent of rot. Most University City homes have sound decks, but pre-1950 homes and properties with a history of roof leaks are at higher risk. If you suspect rot (soft spots, discoloration, or a musty smell in the attic), mention it to the inspector during the initial deck inspection conversation.
Can I pull a roof permit for an investment property or rental unit in University City?
Yes, but you must use a City-of-University-City-licensed roofing contractor — you cannot self-perform as an owner-builder on non-owner-occupied property. The contractor pulls the permit using their license. Permits for rental or investment properties are issued the same way as owner-occupied roofs, but the contractor relationship is mandatory. Verify contractor licensing before hiring.
What happens if I re-roof without a permit and try to sell my house?
Unpermitted roof work must be disclosed on the Seller's Disclosure form in Missouri, and most title companies will flag it as an issue. Buyers' lenders will often refuse to finance the sale until the roof is retroactively permitted (at double the original permit fee, $240–$400) and inspected. The unpermitted work can also lower the sale price by 5–10% as buyers demand a discount for the uncertainty. If you discover you should have pulled a permit but didn't, contact the Building Department immediately to discuss retroactive permitting — it's cheaper than dealing with title issues at sale time.
