What happens if you skip the permit (and you needed one)
- Stop-work orders and $500–$1,500 civil penalties per violation day; the city can force removal of unpermitted roofing at your expense.
- Insurance claim denial or coverage cancellation if underwriter discovers unpermitted roof work during loss investigation or policy renewal.
- Disclosure requirement on resale: any unpermitted roof work must be revealed to buyers; expect $5,000–$15,000 negotiation hit or forced removal before closing.
- Lender/refinance block: many mortgage companies will not refinance a property with unpermitted structural work, effectively freezing your equity access.
North Myrtle Beach roof replacement permits — the key details
North Myrtle Beach is a coastal city under the FBC (Florida Building Code) umbrella, which applies to roofing standards even though you're in South Carolina. This means your roof must meet FBC 7th or 8th Edition requirements for wind resistance, secondary water barriers, and fastening patterns — stricter than the IRC in many respects. Any full-coverage roof replacement, tear-off-and-replace job, or change in roof material (shingles to metal, tile, etc.) requires a permit before work starts. Roofing contractors are responsible for pulling the permit in most cases, but if you're acting as your own general contractor, you must file. The city will not issue a permit for roofing work if your property has two existing layers of shingles AND you plan to overlay a third — IRC R907.4 mandates a full tear-off in that scenario. Permits are issued by the City of North Myrtle Beach Building Department, and you'll need to submit your application in person or by the method the department currently accepts (email or online portal if available; call to confirm).
Coastal roofing upgrades are a major cost driver in North Myrtle Beach. The FBC requires secondary water barrier (ice-and-water shield) along eaves, valleys, and around penetrations — typically 24 to 36 inches from the eave edge, depending on exposure. This adds $0.50–$1.00 per square foot to materials. Fastening patterns are also stricter in wind zones: roof shingles may require 6–8 fasteners per shingle instead of the standard 4, and nails must be galvanized or stainless to resist salt-air corrosion. The city's inspectors will check deck nailing patterns in-progress (before new underlayment is installed) and verify final fastening on shingles at final inspection. If your roof deck has rotted or delaminated plywood (common in coastal salt spray and humidity), structural repair or replacement is a separate permit and adds 2–4 weeks to timeline. Metal roofing is increasingly popular in North Myrtle Beach for salt-air durability; if you switch to metal, you must submit installation details showing fastening, underlayment, and flashing specs — often a harder sell to the permit office than like-for-like shingle-to-shingle replacement.
The 3-layer rule is enforced strictly in North Myrtle Beach. Before submitting your permit application, your contractor should climb the roof and count existing layers of shingles (or roofing material). If there are already two layers, and you propose a third, the city will deny the permit and require tear-off. Some older homes near the beach have multiple layers from previous owners' overlays. If you discover three layers during work after permit approval, inspectors will issue a stop-work order until a change order is filed and approved, adding 2–3 weeks and $500–$1,200 in tear-off labor. The reasoning is structural: additional weight on the roof deck can exceed design loads, especially when combined with wind and wet conditions in coastal storms. Check your roof before meeting with a contractor.
Plan-review timeline depends on scope. Like-for-like replacements (same material, no structural changes, standard secondary water barrier) are often issued over-the-counter in 1–3 business days. Material changes, structural deck repairs, or non-standard details (e.g., solar attachment points, custom flashing) trigger full plan review, which can take 2–4 weeks. The Building Department may request engineered drawings if you're changing from shingles to tile or metal, or if your roof slope is under 4:12 pitch (which requires additional specifications per FBC). Roofing contractors in the area are accustomed to these timelines and often pad their proposal schedules accordingly. Inspections occur in two phases: rough-in (after tear-off and deck nailing, before underlayment/shingles are installed) and final (after all roofing is installed, fasteners are checked, and flashing is sealed). Some contractors schedule these same day if weather cooperates; plan on at least 2 inspection visits.
Permit fees in North Myrtle Beach are calculated based on the valuation of work. For roof replacement, the city typically charges $1.50–$3.00 per $100 of estimated labor and materials, with a minimum of $150–$200. A 2,000-square-foot re-roof (about 20 squares) with asphalt shingles is typically valued at $6,000–$12,000, resulting in a permit fee of $150–$350. If you're adding structural work, secondary barrier upgrades, or changing materials, fees can climb to $400–$600. Ask your contractor for their project valuation estimate and confirm the fee with the city before submitting; fees are non-refundable once applied. Some properties near sensitive wetlands or in the floodplain may trigger additional environmental review, adding $100–$250 and 1–2 weeks to the timeline. Confirm your property's flood zone and wetland status with the Building Department before bidding the job.
Three North Myrtle Beach roof replacement scenarios
FBC vs. IRC: Why North Myrtle Beach roofs are built differently
North Myrtle Beach adopts the FBC (Florida Building Code) as its roofing standard, not the IRC (International Residential Code) that most of the country uses. The FBC is more stringent on wind resistance, water intrusion, and hurricane preparedness — even though you're in South Carolina, the coastal location justifies the FBC adoption. This means your re-roof will be engineered to withstand sustained 140+ mph winds and driving rain at a 45-degree angle, conditions that rarely occur in North Myrtle Beach but are part of the code safety margin. The FBC requires secondary water barrier (ice-and-water shield or equivalent) along eaves to a depth of at least 24 inches, plus around any roof penetration (vent pipes, chimneys, skylights). The IRC allows for more flexibility in certain climates; the FBC does not. Fastening patterns are also tighter: FBC zones may require 8 fasteners per shingle in edge conditions, versus 4 in the IRC field. Underwriters and insurance companies are aware of this difference, and some offer small discounts on homeowner's insurance if your roof is FBC-compliant. When you call the Building Department, ask specifically whether they're enforcing FBC 7th or 8th Edition; the difference is minor for residential roofing, but 8th Edition tightens flashing around skylights and solar penetrations.
The 3-layer rule and why tear-offs cost money
IRC R907.4 prohibits roof coverings from being applied over more than one existing layer of roof covering. North Myrtle Beach enforces this strictly. If your inspector finds a second layer already installed, you cannot apply a third — you must tear off both old layers and start fresh. The reasoning is load-bearing: additional weight compounds, and in a coastal storm with wind suction and rain saturation, the extra weight can exceed the roof deck's design capacity. Additionally, older shingles underneath a new layer trap moisture and create conditions for mold and deck rot that won't be visible until the problem is severe. Tear-offs cost money — typically $0.75–$1.50 per square foot, or $1,200–$3,000 on a 2,000-sq-ft roof. Some contractors will take the risk and apply a third layer anyway, betting that inspectors won't catch it or that the homeowner won't report it; this is a recipe for insurance denial and forced removal. Before accepting a bid, ask your contractor to climb the roof and certify in writing how many layers exist. If the bid says 'overlay,' ask why and get clarification on the layer count. If you have two layers and want to stick with an overlay, confirm with the Building Department that a third layer is permitted; the answer will be no.

Common questions
Can I re-roof my home myself, or does a licensed contractor have to pull the permit?
South Carolina allows owner-builders to pull permits for their own property (SC Code § 40-11-360), including roofing. However, North Myrtle Beach may require proof of ownership and may ask you to certify that you're performing the work yourself, not hiring an unlicensed worker. The Building Department's position varies by inspector; call ahead to confirm. If you hire a roofer, they must pull the permit (they're the prime contractor). Do not ask an unlicensed worker to 'help' — the city may interpret that as you acting as a general contractor without a license, risking fines.
What's the secondary water barrier, and why is it so expensive?
The secondary water barrier is a sticky membrane (ice-and-water shield) that goes under your shingles along eaves and valleys. In North Myrtle Beach, the FBC requires it to extend 24–36 inches from the eave edge and around all penetrations (vents, chimneys, skylights). It costs about $0.50–$1.00 per square foot and is mandatory in coastal zones because it catches wind-driven rain that gets under shingles during storms. Without it, water leaks into the deck and attic. It's not an upsell — it's a code requirement. Your permit will be denied if the application doesn't specify it.
My roof has two layers. Can I just add a third without tearing off?
No. IRC R907.4 and the FBC both prohibit it. North Myrtle Beach Building Department will not issue a permit for a three-layer roof. If an inspector discovers a third layer has been installed, a stop-work order is issued, the contractor must remove it, and you pay for the removal out-of-pocket. Budget for a tear-off ($1,500–$3,000) if you have two layers.
How long does the permit process take?
Like-for-like replacements (same shingle material, no structural work) are often issued over-the-counter in 1–2 business days. Material changes (shingles to metal, tile, etc.) or structural repairs trigger full plan review, which takes 2–4 weeks. Once the permit is issued, construction typically takes 5–10 business days depending on weather. Total project timeline is 1–2 weeks for simple jobs, 6–8 weeks for complex ones.
What if I discover roof rot during tear-off?
Notify your contractor immediately. They should stop work, take photos, and contact the Building Department to report the discovery. A structural engineer may be called to assess the rot and specify repair or replacement. A change order and permit amendment (sometimes a separate permit) will be needed. This adds $500–$1,500 and 1–2 weeks to the timeline. Always budget 10–15% contingency for this scenario.
Does North Myrtle Beach offer permits online, or do I have to submit in person?
As of 2024, the city accepts permit applications in person at City Hall. Confirm current submission methods (email or online portal) by calling the Building Department or visiting the city website. Some jurisdictions in SC have adopted e-Permit or similar platforms; North Myrtle Beach's status varies. Calling ahead saves a trip.
If I don't get a permit, can the city force me to remove the roof?
Yes. If unpermitted roofing is discovered (by inspector, neighbor complaint, or insurance audit), the city can issue a notice of violation and order removal at your expense. Costs can exceed $3,000–$5,000. Additionally, homeowner's insurance may deny claims related to the roof, and resale disclosure requirements will hurt your property value. The permit fee ($150–$350) is a bargain compared to the risk.
What are FBC and IRC, and why does North Myrtle Beach use one over the other?
The IRC (International Residential Code) is the baseline standard for most of the U.S. The FBC (Florida Building Code) is a stricter coastal standard designed for hurricane zones. North Myrtle Beach, being coastal, adopts the FBC for wind resistance and water intrusion. The FBC requires tighter fastening, secondary water barriers, and stronger connections. It costs more upfront but offers better storm protection and may reduce insurance premiums.
Can I change from asphalt shingles to metal or tile without special permits?
Material changes require a permit and may require engineered drawings. Metal roofing requires fastening details and underlayment specs. Tile requires structural evaluation (tile is heavier and may exceed the roof deck's design load). Plan on 3–4 weeks for plan review and $400–$600 in permit fees for material changes. Like-for-like replacement is much simpler.
How much will the permit cost for my roof?
North Myrtle Beach calculates permit fees based on the estimated value of work, typically $1.50–$3.00 per $100 of project cost, with a minimum of $150–$200. A standard 2,000-sq-ft asphalt shingle re-roof ($6,000–$12,000 project value) costs $150–$350 for the permit. Structural work, material changes, and engineered drawings increase fees to $400–$600. Ask your contractor for the proposed project valuation and confirm the fee with the city before submitting.
