On April 20, 2024, Rock Hill took a direct hit from 4-inch hailstones and 80-90 mph winds that carved a 22-mile path through the city. Five months later, Tropical Storm Helene set a record 34,000 power outages. If your home is still recovering, Palm Build brings the capacity, expertise, and insurance documentation to finish what the storm started.

The single most destructive local weather event in recent Rock Hill history — 4-inch hailstones, 80-90 mph winds, and a 22-mile damage swath that triggered a formal IBHS investigation. Nearly two years later, the compound damage from this event continues to generate restoration calls across York County.

Of the damage swath
The Insurance Institute for Business & Home Safety conducted a full post-event investigation in collaboration with four insurance companies — a level of scrutiny typically reserved for the most damaging storms in the nation. Their findings documented catastrophic failure of building materials across the impact zone.
IBHS confirmed that conventional asphalt shingles were damaged regardless of age within the most severe hail zone. Impact-rated Class 4 shingles performed measurably better, but the vast majority of Rock Hill homes — including newer construction in Sweetwater Plantation and Eastview — had standard-rated shingles.
Vinyl siding on 2000s-era homes throughout Southside, Sweetwater Plantation, and the I-77 corridor was described as "shredded" by investigators. The compromised building envelope allowed water intrusion during subsequent rain events — setting up the compound damage that persists today.
The Southside neighborhood bore the worst damage. SC Public Radio documented homes with 10-foot holes in roofs covered only by blue tarps eight months after the event. Structural tree falls onto homes compounded the hail and wind damage. Many Southside homes experienced compound damage when Helene arrived five months later.
September 2024
As Helene tracked north through South Carolina, Rock Hill experienced record-breaking power outages, mandatory evacuations along the Catawba River, and devastating compound damage on homes still recovering from April's hailstorm.
83 yrs
Record since cooperative founded
York Electric Cooperative recorded 34,000 simultaneous member outages — the most in the cooperative's 83-year history, rivaling Hurricane Hugo. Extended power loss left homes without HVAC dehumidification, accelerating mold growth in already-moisture-compromised structures.
4-5 ft
Expected additional river rise
Mandatory evacuations were ordered south of Mountain Island Lake as the Catawba River was expected to rise an additional 4-5 feet. Riverwalk residents and waterfront properties in the India Hook corridor faced direct flood exposure as Duke Energy released water over spillways.
5 months
Between hail event and Helene
Helene arrived just five months after the April hailstorm. Homes that couldn't complete roof repairs before September had interior water damage dramatically worsened by Helene's heavy rainfall — driving water through compromised roofing, into wall cavities, and down into crawl spaces.
$1.48B
Statewide damage from Helene
Kings Drive and the College Downs area flooded to knee depth even before peak rainfall arrived. Combined with the $1.48 billion in statewide damage and over 1.3 million power outages across South Carolina, Helene overwhelmed local response capacity and created restoration backlogs lasting months.
Neighborhood Storm Profiles
Storm vulnerability in Rock Hill varies by construction type, drainage infrastructure, and proximity to waterways. This neighborhood-level intelligence helps homeowners understand their specific risk profile.
Built: 1940s-1970s
Primary risk: Hail + wind + compound water intrusion
Storm profile: Ground zero for April 2024 hailstorm. Documented 10-foot roof holes, shredded vinyl siding, structural tree falls. Compound damage from Helene 5 months later.
Built: 1950s-1970s
Primary risk: Street flooding + crawl space inundation
Storm profile: Chronic flooding since 1969 worsened by every major storm. January 2024 storm flooded area despite $2.1M city mitigation project.
Built: 1940s-1970s
Primary risk: Stormwater flooding from infrastructure failure
Storm profile: Undersized culverts flood 90+ homes during heavy rain. $14.8M ARPA project underway but construction through Fall 2026.
Built: 2012-2022
Primary risk: River flooding + stormwater
Storm profile: Catawba River proximity triggered mandatory evacuations during Helene. Waterfront lots face direct flood exposure when Duke Energy releases spillway water.
Built: 2008-2019
Primary risk: Hail-damaged building envelope
Storm profile: 2008-2019 vinyl siding and composition shingles severely damaged by April 2024 hail. Slab foundations reduce crawl space risk but building envelope compromise creates water intrusion.
Built: 2000s-2010s
Primary risk: Hail + vinyl siding damage
Storm profile: Near I-77 corridor within the April 2024 hailstorm path. Two-story vinyl siding homes were particularly vulnerable to wind-driven hail.
Built: 1990s-2010s
Primary risk: Wind damage + lake-effect exposure
Storm profile: Lake Wylie proximity adds windstorm exposure. Mixed-age housing means varied roof conditions — older sections most vulnerable.
Built: 1990s-2000s
Primary risk: Aging roof failure during storms
Storm profile: Composition shingle roofs 25-35 years old — well past useful life and highly vulnerable to hail and wind damage.
Our Process
From emergency tarping through final reconstruction, our proven process addresses every layer of storm damage — including the compound damage scenarios unique to Rock Hill's recent back-to-back weather events.
Call (704) 464-0121 immediately after storm damage. Our crew arrives from Charlotte via I-77 with tarps, board-up materials, and water extraction equipment. During major events like the April 2024 hailstorm, we deploy multiple crews simultaneously across Rock Hill.
Compromised roofs, windows, and siding are secured against further weather exposure. With 44 inches of annual rainfall and no dry season in Rock Hill, rapid board-up prevents the secondary water damage that turns a storm claim into a compound disaster.
We document every point of storm damage: roof impacts, siding penetrations, water intrusion paths, and structural compromise. For hail claims, we photograph individual impact marks with measurement references — the documentation your adjuster needs to approve a full replacement vs. a patch repair.
Storm-driven water is extracted from the structure. For Rock Hill crawl-space homes, we inspect and treat the crawl space — roof leaks drive water through the structure and pool beneath the home. Commercial dehumidifiers and air movers run until every surface reaches its dry standard.
We handle the full scope: roof replacement, siding repair, window replacement, structural framing, and interior finish work. Rock Hill requires building permits for all structural repairs with a 10-business-day plan review — we manage the entire permitting process.
Every repair is inspected for workmanship and code compliance. We provide a written warranty and maintain your project file for future insurance reference. For homes with compound damage from multiple events, we ensure the final restoration addresses all layers of damage.
The Compound Damage Chain
The April 2024 hailstorm didn't just damage roofs — it set off a chain reaction that is still producing restoration calls nearly two years later. Understanding this compound damage timeline is critical for Rock Hill homeowners.
4-inch hailstones and 80-90 mph winds damage roofs and shred vinyl siding across a 22-mile swath. Shingles are cracked, lifted, or torn off. The building envelope is compromised but the interior is initially dry.
Restoration backlogs leave thousands of homes with compromised roofs during Rock Hill's wettest months. Every rain event — and there are dozens, averaging 5+ inches in March alone — drives water through damaged shingles into the attic, wall cavities, and subfloor.
Water migrates through wall cavities and pools in crawl spaces below. Most homeowners are unaware of the extent because the water travels behind drywall. Summer humidity levels exceeding 60% keep every saturated surface wet.
With moisture, warmth, and organic building materials, mold colonizes floor joists, subfloor, wall cavities, and insulation. The stack effect pulls mold spores into the living space. Homeowners notice musty odor and allergy symptoms.
Helene drives heavy rainfall through already-compromised roofs. 34,000 power outages eliminate HVAC dehumidification. College Downs and Kings Drive flood to knee depth. The compound damage chain accelerates — what started as hail damage is now structural water damage with active mold.
If your Rock Hill home was impacted by the April 2024 hailstorm and you're now discovering water damage or mold, you're not alone. The compound damage chain is well-documented and we can help you navigate both the restoration and the insurance claim — even if the original hail claim was filed months ago.

Cost Transparency
Storm restoration costs in Rock Hill have been elevated since the April 2024 hailstorm due to high demand and the prevalence of compound damage. These ranges reflect current York County project costs.
Insurance Navigation
The April 2024 hailstorm exposed thousands of Rock Hill homeowners to insurance complexities they'd never encountered — wind/hail deductibles, ACV settlements, and compound damage claims spanning multiple events. Understanding these traps before you file can save you thousands.
Wind and hail damage to roofing, siding, and windows is covered under standard York County homeowners policies
Water damage resulting from storm-compromised roof or building envelope is typically a covered peril
Wind/hail deductibles are separate from your standard deductible — often 1-2% of dwelling coverage ($3,000-$6,000 on a $300K home)
Older roofs (15+ years) may be settled at Actual Cash Value (ACV) — depreciation is subtracted from the replacement payout
Flood damage from rising water (College Downs, South Rock Hill) requires separate NFIP flood insurance — most Rock Hill homeowners do NOT carry it
Mold from delayed storm damage repair faces $5,000-$10,000 sublimits — easily exceeded in compound damage scenarios
If your roof is 15+ years old, your insurer may settle the claim at Actual Cash Value — meaning they subtract depreciation from the replacement cost. On a roof that cost $15,000 to replace, ACV might pay only $8,000-$10,000, leaving you to fund the gap. Review your policy's roof settlement language before filing.
Our storm damage documentation includes individual hail impact measurements, wind damage patterns, moisture intrusion mapping, and photo evidence with date-stamped metadata. This level of detail supports full Replacement Cost Value claims. See our insurance restoration process guide.
