Union City roof replacement permits — the key details

Union City enforces Georgia residential code (which adopts the 2015 or 2020 IRC with amendments) and prohibits three-layer roofs under IRC R907.4. This is the single most important rule: if your home has two existing shingle layers and you want to add a third, the permit application will be rejected and you'll be ordered to tear off to the deck before proceeding. The building inspector will verify the number of existing layers during the pre-job deck inspection. Most homes in Union City built before 1990 have one or two layers; homes built 1990–2005 often have two. A full tear-off-and-replace (to bare decking) always requires a permit. A roof overlay (new shingles nailed over old) on a one-layer home can sometimes be done without a permit IF it's the second layer and the replacement is like-for-like (same material, same weight). However, the moment you change materials (asphalt shingles to architectural shingles, or shingles to metal), a permit is required even if it's an overlay, because the deck may need reinforcement and the fastening pattern changes.

The City of Union City Building Department accepts roofing permits over-the-counter for like-for-like replacements under 2,000 sq ft of roof area. Submit the completed permit form (available on the city website or at City Hall), proof of ownership or authorization, and a brief scope description (square footage, existing material, new material, whether tear-off or overlay, and the number of existing layers). If you're changing materials, attaching a manufacturer's installation spec is required — this shows the inspector that fastening, underlayment, and flashing will meet code. The permit fee is typically $150–$250 for a single-story home (under 2,500 sq ft) and $250–$350 for larger roofs, calculated at roughly $2–$4 per square of roof area. The city does not charge a separate plan-review fee for standard residential reroofs, but any structural deck repair (replacing rotten rafters, sistering joists, etc.) triggers a $50–$75 structural review add-on. Most permits are issued same-day or next business day if submitted before 2 PM on a weekday.

Inspections for a Union City roof replacement are two-stage: deck inspection (before new decking, underlayment, or shingles go down) and final inspection (after shingles, flashing, and ridges are complete). Call the Building Department at least 24 hours before each inspection. The deck inspector will verify that all old decking is removed (if tear-off), check for rot or structural damage (which may require additional framing repair), confirm fastening patterns on any new plywood (per IRC R602.3, typically 8 inches on center for 7/16-inch OSB), and verify that ice-and-water-shield or roofing underlayment is laid correctly if required. In climate zone 3A, ice-and-water-shield is not mandatory at eaves (it's required only in climate zones 4C and colder), but many roofing contractors install it anyway because it improves water penetration resistance during heavy rain. The final inspector checks shingle nail placement (per manufacturer spec, typically 4 nails per shingle, placed 5/8 inch from the top of the butt), verifies flashing at roof transitions, valleys, and chimneys, and ensures ridge caps are properly sealed. Most inspections take 30 minutes to an hour. Plan for the deck inspection within 1–2 days of starting tear-off, and the final inspection within 1–2 days of completing the roof.

Union City homeowners are allowed to pull roofing permits for their own homes under Georgia Code § 43-41, which permits owner-builders to construct residential work if they are the owner and occupant. However, if you hire a contractor, the contractor should pull and carry the permit. Many Union City roofing contractors automatically include the permit fee in their bid, but confirm this — ask for the permit invoice separately and check that the contractor's license is valid (search Georgia Secretary of State for roofing contractor registration). A common mistake is assuming the contractor 'got the permit' when they didn't; Union City's Building Department has a public records system, and you can call to verify before work starts. If you discover mid-project that no permit was pulled, stop work immediately and call the Building Department to discuss a retroactive permit and inspection plan. Do not ignore a stop-work order; the fine doubles if you ignore it.

Material-specific rules and underlayment requirements depend on what you're installing. For standard asphalt shingles, use 30-pound roofing felt or synthetic underlayment per the shingle manufacturer's spec; the permit application should note this. For metal roofing, a secondary water barrier (ice-and-water-shield or peel-and-stick membrane) is recommended at eaves and valleys because metal can conduct cold and cause condensation — this is not required by code in zone 3A but is best practice. For tile or slate, the deck must be evaluated for additional load capacity (typically 12–15 lbs per sq ft for composition shingles vs 15–20 for tile); if a structural engineer's letter is required, add 1–2 weeks to the timeline and $300–$600 to the cost. For metal roofing over 6:12 pitch, ensure the underlayment manufacturer allows metal fasteners; some underlayments specify 'no metal or copper fasteners.' Always provide the manufacturer's installation instructions with the permit application if the material is non-standard.

Three Union City roof replacement scenarios

Union City's three-layer rule and why it matters to your permit

IRC R907.4 prohibits more than two roof layers, and Union City enforces this strictly. The reason is simple: three layers trap moisture, accelerate rot, and make future repairs harder. Inspectors in Union City are trained to count existing layers during the deck inspection — they'll look at the roof edges, ask about previous reroofs, or even pull a shingle sample to count. If two layers are found and you want to add new shingles, the permit application will be rejected with a note: 'Tear-off to deck required per IRC R907.4.' This can be a shock if a homeowner or contractor assumed an overlay was acceptable. To avoid this, ask your roofer to inspect the roof layers before getting a bid. Walk the attic with them and count: one layer = you can overlay or tear-off; two layers = tear-off required and permit required. If you're unsure, schedule a pre-permit consultation with Union City Building Department (free, usually 15–20 minutes by phone). Provide your roof age, recent reroofing history if known, and the type of material currently installed. The inspector can often give you a yes/no answer on whether a permit is needed without seeing the roof in person.

If a roofer starts work and discovers a third layer mid-project, Union City Building Enforcement can issue a stop-work order ($250–$500 fine) and require the contractor to complete tear-off at the homeowner's expense. This is a common expense surprise. Always get a tear-off cost estimate separately from the overlay cost so you're prepared. In some cases, homeowners have tried to negotiate a 'roof underlayment inspection' (sending the Building Department an inspector to certify the layer count before permit approval), which costs $50–$150 but can save thousands if it reveals a two-layer roof early. Union City doesn't formally require this, but it's a smart risk-mitigation step if you're uncertain about your roof's history.

The three-layer rule also applies to re-roof jobs where you're adding a secondary water barrier (ice-and-water-shield or peel-and-stick membrane). If you're overlaying and adding ice-and-water-shield over existing shingles, the inspector may count the shingles + membrane + new shingles as three layers in some interpretations. To avoid confusion, communicate with Union City Building Department before pulling the permit: clarify whether ice-and-water-shield under new shingles (over an existing one-layer roof) counts as two layers or three. Most inspectors accept this as two layers (existing shingles + new shingles, with the membrane as a flashing/underlayment, not a separate layer), but getting written confirmation is worth a 10-minute call.

Typical Union City roofing permit timeline and inspection workflow

A standard roof replacement permit in Union City (tear-off, like-for-like material, under 2,000 sq ft, single-story) takes 1–3 business days from submission to approval if you submit a complete application during business hours (Mon–Fri, 8 AM–5 PM). Submit in person at Union City City Hall or via email/online portal if available (check the city website for current submission methods). Include the completed permit form (get it from the city or print it online), proof of property ownership or authorization, and a brief description: 'Full tear-off and replacement of asphalt shingle roof with [material], [square footage], [pitch], existing [number] layers.' For like-for-like replacements, a manufacturer's spec sheet is helpful but not always required — ask at submission. The permit is issued as a single job card or folder, and you'll receive a permit number and inspection checklist.

Schedule the deck inspection at least 24 hours before tearing off the roof. Call Union City Building Department with your permit number, preferred date/time, and 2–3 backup times (inspectors often work a rolling route and can't always come on demand). The inspector will arrive within the scheduled 2-hour window (usually 8 AM–4 PM). Have the roof cleared of debris, old shingles removed, and decking fully exposed. The inspection takes 20–40 minutes. The inspector verifies: (1) existing layer count, (2) decking condition (look for soft spots, nail pops, splintering), (3) joist or rafter condition (check for rot, especially around flashing penetrations and eaves), (4) proper nailing pattern if any new decking was installed (IRC R602.3: 8 inches on center for 7/16-inch or thicker OSB/plywood), and (5) ice-and-water-shield layout if applicable. If rot or structural issues are found, the inspector may require a separate structural repair permit or engineer evaluation — this can add $300–$800 and 1–2 weeks.

After deck approval, you proceed with underlayment and shingles. Schedule the final inspection after all shingles are installed, flashing is sealed, and ridge caps are complete. Allow 24–48 hours notice. The final inspection checks: (1) shingle nail placement (per manufacturer spec, typically 4 nails per shingle, 5/8 inch from butt edge), (2) proper flashing at roof transitions, valleys, and penetrations (chimneys, vents, skylights), (3) ridge cap overlap and nailing, (4) no exposed nails or fasteners, and (5) general workmanship and code compliance. If all is correct, the inspector issues a final approval and the permit is closed. If issues are found (e.g., wrong fastening pattern, missing flashing), the inspector will note corrections required ('re-inspect after repairs'). Most Union City roofers budget 1–2 days for corrections. Total time from permit to final approval is typically 1–2 weeks for a straightforward tear-off, plus 1–3 extra weeks if structural work or corrections are needed.
