After a storm hits your Charleston-area roof, work this sequence: (1) stay safe and document the damage from the ground — never climb a wet, compromised roof; (2) check the attic for leaks and daylight; (3) stop ongoing water intrusion with an emergency tarp (keep receipts — your policy requires you to mitigate); (4) get a professional roof inspection (drone + tactile); and (5) notify your insurer promptly — policies require timely notice. The two things that decide your out-of-pocket cost are your policy type (RCV vs ACV) and your coastal deductible (often a percentage-based named-storm or wind/hail deductible). Avoid any contractor who offers to “waive your deductible” — that’s insurance fraud in SC. For coverage questions, your insurer and the SC Department of Insurance are the authorities.

Matt Longo, Owner, Big Bear Roofing — Charleston, SC · Updated July 2026
In the Lowcountry, salt air, humidity, and intense heat quietly pre-weaken a roof, so when severe weather hits — a 58+ mph thunderstorm, quarter-size hail, or a tropical system — Charleston roofs fail faster than inland ones. This guide walks the first hours and days after a storm, how to tell wind from hail damage, and how to get to a fair restoration without getting scammed.
Important: This is general information for SC homeowners, not legal, structural, or insurance advice. Coverage depends on your specific policy. For official rules, contact the South Carolina Department of Insurance (SC DOI) at doi.sc.gov, and read your policy.
How to Tell Storm Damage Apart: Wind vs. Hail vs. Debris
The National Weather Service classifies a thunderstorm as severe at 58+ mph winds, 1-inch (quarter-size) hail, or a tornado. Different forces leave different signatures:
Wind damage
Wind works like air over an airplane wing — lifting and suctioning at the edges, eaves, and ridges, usually on the windward side.
- Asphalt shingles: wind breaks the adhesive seal strip that bonds shingles. Even if a shingle drops back into place, the broken seal means it can no longer shed water; bending leaves a horizontal crease (a functional failure). One loose shingle exposes the next, peeling off sections over time.
- Metal: durable to very high winds, but extreme gusts can bend panels, loosen fasteners at the seams, and warp edge flashing.
- Look for: shingles in the yard, bald patches of exposed underlayment, curled edges, and bent/loose flashing.
Hail damage
Hail damages by impact, and severity scales with size: 1″ (quarter) is the reportable threshold, 1.75″ (golf ball) functionally damages virtually all standard asphalt shingles, and 2.5″ (tennis ball) can punch through shingles and crack the decking.
- Asphalt shingles: circular bruises that feel soft, dark shiny bald spots where the asphalt is exposed, and heavy granule loss (colored grit in your gutters and downspouts is a telltale sign).
- Metal: dents and dimples — often “cosmetic,” but hard hits can compromise the protective coating, which in Charleston’s salt air leads to accelerated corrosion.
- Class 4 impact-resistant shingles (which pass the UL 2218 2-inch steel-ball test) resist hail far better and may qualify for an insurance premium discount — phrasing and amount vary by carrier.
Wind-driven debris
Branches and flying objects leave localized punctures, gouges, and tears — erratic, concentrated damage rather than the uniform pattern of wind or hail.
The First 72 Hours: Safety, Documentation & Mitigation
What you do (or skip) in the first few days drives the entire claim.
Step 1 — Stay safe; document from the ground
The NRCA warns homeowners not to climb onto a storm-damaged roof — wet surfaces, hidden structural damage, and downed power lines make it dangerous. Document safely from the ground:
- Wide shots of the whole property, medium shots of each slope, close-ups of dented gutters, battered AC units, and shingles in the yard.
- If you can do so safely, photograph a few hailstones next to a coin or ruler to prove hail size.
- Screenshot a weather app or news report to timestamp the storm.
Step 2 — Check the attic
With a flashlight, look for daylight through the deck, fresh water stains on rafters or insulation, mold, musty smells, or piles of granules below vents — early evidence the envelope has failed.
Step 3 — Stop the water (emergency tarp)
Your policy requires you to mitigate further damage. A tarp is a temporary, waterproof measure (not a repair) — keep all receipts, as emergency mitigation is typically reimbursable.
- After a presidentially declared disaster, FEMA / U.S. Army Corps “Operation Blue Roof” installs free heavy-duty tarps for qualified homeowners (apply at blueroof.gov or 1-888-ROOF-BLU). Eligibility generally requires a primary residence with no more than ~50% of the roof framing damaged, a shingle-type roof (metal evaluated case-by-case), and a signed Right-of-Entry form.
- Because demand often outpaces the program, many homeowners hire a licensed roofer to tarp immediately to satisfy the insurer’s mitigation requirement.
Step 4 — Notify your insurer promptly
SC law doesn’t set a strict day-one deadline, but most policies require prompt notice of loss, and every week of delay blurs the line between storm damage and wear. Make only temporary repairs until the adjuster has seen the damage.
The Professional Inspection: Drone + Tactile
Ground-level looks can’t confirm functional damage, so a real inspection layers three methods:
| Tier | What it does | Why it matters |
|---|---|---|
| Ground & attic | Perimeter walk + interior attic check | Safest; documents collateral damage and interior water intrusion — key adjuster evidence. |
| Drone-assisted | High-res aerial scan | No fall risk; reaches steep/complex roofs with HD imagery of every slope. Can’t “feel” a soft bruise. |
| On-roof tactile | Inspector physically checks bruises, seals, flashing | The gold standard for confirming functional damage — when the structure is safe to walk. |
The strongest damage report combines attic findings, high-definition drone imagery, and a careful tactile check. Big Bear’s free inspections include drone-assisted documentation you can hand to your insurer.
Charleston Insurance Realities: RCV vs ACV & Coastal Deductibles
How much you pay comes down to two things. (For the full claim process — adjuster meetings, supplements, appraisal, and denials — see our SC insurance-claim guide.)
- RCV vs ACV. RCV pays full replacement cost (ACV first, then recoverable depreciation on completion); your main cost is the deductible. ACV pays the depreciated value — a 15-year-old roof may only return 40–60% of replacement cost, leaving a large gap plus the deductible.
- Coastal percentage deductibles. Inland policies use a flat “all-other-perils” deductible ($500–$2,500). Coastal SC policies commonly use a percentage of your dwelling coverage (often 1%–5%, sometimes up to 10%). On a $500,000 home, a 2% deductible is $10,000 — and you don’t write that check to the insurer; the insurer subtracts it from your payout, and you fund that difference to your contractor.
- Know which deductible you have — the wording matters:
– Wind/hail deductible — triggers on any wind or hail damage (even an afternoon thunderstorm).
– Named-storm deductible — triggers only for an NWS/NHC-named storm (including tropical storms).
– Hurricane deductible — narrower; triggers only for a declared hurricane.
- SC DOI Regulation 69-56 requires insurers to disclose a separate named-storm or wind/hail percentage deductible prominently on the policy face, with a worked mathematical example — so check your declarations page. [SC DOI]
How Long Does It Take? The Restoration Timeline
- Days 1–21 — discovery & adjuster. File promptly; under SC law (S.C. Code § 38-59-20) insurers must handle claims with reasonable promptness (SC doesn’t set a single fixed pay-by deadline — confirm timing with the SC DOI). Adjusters typically inspect within 7–14 days — but after a regional hurricane, that can stretch to 3–6 weeks.
- Weeks 2–6 — approval & permitting. The insurer issues a scope of loss and (on RCV) a first ACV check; your contractor pulls local permits (a few days to ~3 weeks, longer if coastal high-wind plans need review). Where an insurer’s refusal to pay a covered claim is without reasonable cause, SC law (§ 38-59-40) can expose it to your attorneys’ fees.
- Weeks 4–12 — install & final payment. Tear-off and a standard asphalt re-roof usually takes 1–3 days (metal or extensive decking repair, 3–7 days). After it passes inspection, the contractor submits completion docs and the insurer releases the recoverable depreciation. End to end is typically 3–12 weeks, but post-hurricane supply shortages can push it to 4–6 months.
Don’t Get Scammed: Storm Chasers After a Charleston Storm
Post-disaster fraud spikes after every major storm. Watch for these red flags from out-of-town “storm chasers”:
1. Unsolicited door-knocking — “we were just in the neighborhood” / “we have leftover materials.”
2. “We’ll waive your deductible” / “free roof” — insurance fraud in SC: S.C. Code §40-59-25 bars contractors from paying or rebating deductibles, and burying one requires submitting an inflated invoice to the insurer (§38-55-540 insurance fraud). It exposes you to prosecution. A legitimate roofer never offers it.
3. Manufactured damage — bad actors offering “free inspections” who covertly damage the roof to fabricate a claim.
4. High-pressure tactics, blank contracts, and AOBs — artificial urgency, contracts with prices “filled in later,” or pressure to sign an Assignment of Benefits or sign the insurance check over to them (which hands them your claim).
5. Big upfront cash demands — a modest deposit is normal; demands for 50–100% upfront (especially by wire, gift card, app, or crypto) are a scam signature.
How to hire safely: verify the contractor’s license on the SC LLR Licensee Lookup, demand a certificate of insurance (general liability and workers’ comp), insist on a written contract, and choose a locally established company that will still be here to honor the warranty. In SC, virtually all residential roofing work requires a Residential Specialty Contractor registration (and commercial work above $10,000 requires a state contractor’s license — the threshold was raised from $5,000 in 2023); unlicensed contracting is a misdemeanor.
Frequently Asked Questions
How do I know if my roof has storm damage?
Look from the ground for shingles in the yard, exposed underlayment, curled or creased shingles, bent flashing, dented gutters, and heavy granule grit in downspouts. Confirm with a professional drone + tactile inspection — much functional damage (broken seals, soft hail bruises) isn’t visible from the ground. [Big Bear]
Should I get on my roof to check after a storm?
No. The NRCA advises against it — wet, compromised roofs and downed power lines are dangerous. Document from the ground and the attic, and let a professional inspect the surface. [NRCA]
What is a named-storm or hurricane deductible?
A separate, percentage-based deductible (often 1–5% of your dwelling coverage) that applies to coastal storm damage. A “named-storm” version triggers for any NWS/NHC-named storm; a “hurricane” version only for a declared hurricane; a “wind/hail” version for any wind or hail loss. Check your declarations page. [SC DOI]
Can a contractor waive my insurance deductible in South Carolina?
No — it’s insurance fraud, because covering your deductible requires inflating the claim to the insurer. Both the contractor and homeowner can be penalized. Avoid anyone who offers it.
How long does a storm-damage roof replacement take in Charleston?
Often 3–12 weeks end to end — the install itself is usually 1–3 days for asphalt — but after a regional hurricane, adjuster backlogs and material shortages can extend it to 4–6 months.
What is Operation Blue Roof?
A free FEMA / Army Corps program activated after major declared disasters that installs heavy-duty temporary tarps for qualified homeowners (apply at blueroof.gov or 1-888-ROOF-BLU). It’s emergency protection, not a permanent repair.
