Coastal Georgia Storm Roof-Damage Field Report

Brushed Coastal GA as a Category 1-2 with mandatory evacuation of Tybee Island. The Savannah stations recorded sustained winds near 50 mph gusting past 70 mph, while Tybee itself recorded 75 mph sustained, and shingle uplift was widespread inland. Older 4-nail asphalt roofs across the Historic District and Ardsley Park lost ridge caps and starter strips by the dozen.

Roofing takeaway: 6-nail patterns and reinforced starter strips are our standard on every Chatham County install.

Tropical-storm-force winds covered all of Coastal Georgia with heavy rain. Oak strike was the dominant damage mode for Savannah residentials — mature live oaks along Forsyth Park and the Bull Street corridor dropped limbs onto roofs and skylights through the night.

Roofing takeaway: Tree impacts can create openings that warrant prompt, safe assessment. Temporary stabilization timing depends on weather, access, storm volume, materials, and crew availability, and no fixed cost outcome is guaranteed.

Florida Big Bend Cat 4 landfall with devastating tree damage all the way inland to Augusta. Isle of Hope and Ardsley Park took the heaviest oak-strike claims in Chatham, and pine snapping was the dominant rural damage mode in Bulloch and Effingham.

Roofing takeaway: Helene proved that hurricane straps and ring-shank nailing pay for themselves the first time a 200-year oak comes down on the deck.

Brushed Coastal GA as a Category 1-2 with mandatory evacuation of Tybee Island — the first full island evac since Floyd. Sustained winds of 75 mph on the island, gusting to 96 mph, and storm surge across the back river ate older 4-nail asphalt roofs from Butler Avenue to Fort Screven; ridge caps and starter strips were the dominant island-wide loss.

Roofing takeaway: 6-nail patterns and reinforced starter strips are our standard on every Tybee reroof — 4-nail shingles do not survive a Cat 1 brush at this latitude.

Tropical-storm-force winds covered the entire Georgia coast with bands of heavy rain over Tybee for nearly 18 hours straight. The wind didn't break records — the saturation did. Underlayment that hadn't been replaced in a decade gave up first.

Roofing takeaway: Peel-and-stick ice & water shield in place of felt underlayment is our Tybee default — long-duration tropical rain is the threat, not just peak wind.

Cat 3 Florida Big Bend landfall; as the system tracked north, the NHC report records 2-4 feet of storm-surge inundation above ground level along the Georgia coast. North Beach saw the worst of the surge-driven driftwood and debris damage; back-river docks and the lower courses of stilt-home siding took most of the hit.

Roofing takeaway: Idalia confirmed that surge accelerates corrosion on already-compromised galvanized fasteners — the salt that gets driven into a roof during a surge event is the worst kind of exposure.

Category 4 Florida Big Bend landfall with damage running all the way to Augusta. Tybee got off lighter than inland Chatham — Isle of Hope and Ardsley Park took the brunt of the oak-strike claims.

Roofing takeaway: After Helene, current wind-mitigation records helped owners document installed roof features. Each carrier independently decides what records it requires and how quickly it evaluates a claim.

Sustained winds near 50 mph (gusting past 70 mph) at the Savannah stations stressed flat-roof terminations on Hwy 21 warehouses adjacent to Garden City Terminal, with torn membrane edge metal and lifted parapet copings on aged single-ply assemblies in 31408. Mechanically attached membranes generally held; older fully adhered systems past 15 years saw the most edge-detail failures, and residential shingle uplift hit the older 4-nail installs in the surrounding neighborhoods.

Roofing takeaway: Mechanically attached membrane with reinforced parapet termination bars is the specification to ask for on a Garden City flat roof, and 6-nail patterns are our residential standard in 31408.

Tracked across south Georgia after a Category 3 Florida Big Bend landfall. NWS Charleston logged a 40 mph gust at the I-95 Chatham weigh station and 52 mph at Savannah/Hilton Head International, with 66 mph in Savannah and shingle uplift on newer Pooler-corridor subdivisions just west of Garden City; no hail was reported anywhere in Georgia on August 30-31, 2023 (SPC storm reports). For the Hwy 21 logistics corridor the exposure in a storm like this is wind at membrane edges and ponding during the rainbands rather than impact, so the post-storm checks on aged single-ply are edge-metal terminations, parapet copings and scupper or drain capacity.

Roofing takeaway: Idalia was a wind-and-rain event here, not a hail event: on aged single-ply the details that decide how a near-end-of-life membrane fares are edge terminations and drainage, not impact, and documented pre-storm inspection photos provide a useful baseline for comparing post-storm roof conditions.

Category 4 Florida Big Bend landfall sent damaging winds inland to Statesboro and Augusta. In the Garden City industrial corridor, airborne debris struck rooftop HVAC and process equipment on several Hwy 21 warehouses, and a few aged modified-bitumen roofs in 31408 took blow-offs at unreinforced parapet corners where prior repairs had skipped membrane re-termination.

Roofing takeaway: Helene reinforced that reinforced rooftop equipment curbs and full parapet re-termination during recovers pay for themselves the first time a debris-loaded gust hits the deck.

Brushed Coastal GA as a Category 1-2 with tropical-storm-force winds across Bryan County. Older 4-nail subdivision roofs along the I-95 corridor lost ridge caps and starter strips by the dozen, and the pine canopy across Richmond Hill Plantation and Belfast Keller dropped enough limbs to keep tree crews busy for weeks.

Roofing takeaway: 6-nail patterns and reinforced starter strips are our standard on every Bryan County install — the older 4-nail spec is the first to fail.

Tropical-storm-force winds covered all of Bryan County with heavy rain. Oak strikes on older Richmond Hill streets and pine snapping out toward the Belfast River drove the bulk of residential claims.

Roofing takeaway: Irma showed how tree and wind damage can create roof openings that warrant prompt, safe assessment. Temporary stabilization timing depends on weather, access, storm volume, materials, and crew availability, and no fixed cost outcome is guaranteed.

Category 3 Florida Big Bend landfall, tracked across south Georgia. Newer subdivision roofs along the I-95 / Hwy 17 corridor — many on builder-grade shingles applied with the older nailing schedule — saw widespread shingle uplift across Bryan and Effingham counties.

Roofing takeaway: Idalia showed that builder-grade roofs in 2000s Bryan County subdivisions often fail at the starter strip first — replacing them now beats waiting for the next storm.

Category 4 Florida Big Bend landfall with devastating tree damage all the way inland to Augusta. Pine snapping was the dominant rural damage mode across Bryan, Bulloch, and Effingham counties — the heavily wooded Richmond Hill Plantation and Belfast Keller subdivisions saw repeated pine strikes through the night.

Roofing takeaway: Helene proved that a pre-season pine assessment around Richmond Hill homes matters more than any extra wind nail — most claims here were tree, not wind uplift.

Matthew brushed Coastal Georgia as a Cat 1-2 with sustained winds near 50 mph (gusting past 70 mph) at the Savannah stations. Pooler's open-field subdivisions caught strong gusts, especially around Godley Station and the Pooler Parkway corridor, exposing how thin many original builder-grade 4-nail installations really were.

Roofing takeaway: 6-nail patterns and reinforced starter strips are our standard on every Pooler install — the 4-nail builder spec simply does not survive Chatham wind.

Idalia made Cat 3 landfall in the Florida Big Bend and tracked across south Georgia. Pooler sat on the weak side of the track: NWS Charleston logged a 32 mph gust 2 miles northeast of Pooler and 52 mph at Savannah/Hilton Head International, against 66-69 mph at Savannah and South Tybee, and no hail was reported anywhere in Georgia on August 30-31, 2023 (SPC storm reports). Where Idalia found builder-grade 4-nail installs in the newer Pooler Parkway-corridor subdivisions the mode was lifted tabs and starter strips, not impact.

Roofing takeaway: Idalia's uplift pattern reinforced the need to select fastener type and attachment details from the roofing system approval, roof deck and zones, project exposure, and permitted scope.

Helene's Cat 4 Big Bend landfall produced devastating tree damage across coastal Georgia, with pine snapping the dominant rural mode. In Pooler, the older established trees lining the original Pine Barren Road corridor and the mature pines around Hunter's Ridge produced tree-strike claims, while the newer open-lot subdivisions got off lighter on tree damage but saw repeated wind uplift on aging builder-grade roofs.

Roofing takeaway: Helene confirmed that Pooler has two distinct roofing risk profiles — older tree-shaded streets need pre-storm tree assessment, newer open subdivisions need high-wind hardening.

Sustained winds near 50 mph (gusting past 70 mph) at the Savannah stations with shingle uplift on residential roofs along the Hwy 21 corridor and torn membrane terminations on several Garden City Terminal-adjacent warehouses. Older 4-nail asphalt installs in Rice Hope lost ridge caps and starter strips in the gusts off the Savannah River.

Roofing takeaway: Mechanically attached membrane with reinforced parapet termination bars is the specification to ask for on a Port Wentworth flat roof, and 6-nail patterns are our residential standard in 31407.

Tropical-storm-force winds and heavy rain stressed flat-roof drainage across the Hwy 21 industrial corridor, with several warehouses ponding past deflection limits where scuppers were undersized. Residential damage was lighter — mostly oak limbs and gutter strikes in Rice Hope rather than shingle loss.

Roofing takeaway: Overflow scuppers sized to IBC code are non-negotiable on every Port Wentworth flat-roof retrofit, regardless of how clean the primary drain layout looks.

Tracked across south Georgia after a Category 3 Florida Big Bend landfall. NWS Charleston logged a 40 mph gust at the I-95 Chatham weigh station and 52 mph at Savannah/Hilton Head International, with 66 mph in Savannah and shingle uplift on newer Pooler-corridor subdivisions just south of Port Wentworth; no hail was reported anywhere in Georgia on August 30-31, 2023 (SPC storm reports). For the Hwy 21 corridor the exposure in a storm like this is wind at membrane edges and ponding during the rainbands rather than impact, so the post-storm checks on aged single-ply are edge-metal terminations, parapet copings and scupper or drain capacity.

Roofing takeaway: Idalia was a wind-and-rain event here, not a hail event: on aged single-ply the details that decide how a near-end-of-life membrane fares are edge terminations and drainage, not impact, and documented pre-storm inspection photos provide a useful baseline for comparing post-storm roof conditions.

Category 4 Florida Big Bend landfall with devastating tree damage inland to Augusta and Statesboro. Pine snapping was the dominant rural mode in Effingham; in Port Wentworth, oak strikes hit Rice Hope homes and a handful of Hwy 21 warehouses took rooftop equipment damage from airborne debris.

Roofing takeaway: Helene reinforced that ring-shank nailing and reinforced rooftop equipment curbs pay for themselves the first time a 60-foot pine or oak comes down across the deck.

Matthew tracked the Georgia coast as a Category 1-2 with Glynn County under mandatory evacuation. Brunswick took sustained tropical-storm-force winds, scattered shingle uplift across older 31520 housing stock, and the Sidney Lanier Bridge closed for hours during the peak.

Roofing takeaway: 6-nail patterns and reinforced starter strips are our standard on every Brunswick install — 4-nail roofs from the 90s and early 2000s shed ridge caps wholesale.

Dorian paralleled the Georgia coast offshore as a major hurricane, raking Glynn County with sustained tropical-storm winds and beach erosion on St. Simons. Brunswick saw fascia and shingle damage along the immediate coast plus salt-spray loading miles inland — more than enough to accelerate corrosion failure on any roof still running galvanized fasteners.

Roofing takeaway: A storm that stays offshore, as Dorian did here, still salts the entire roof assembly hard enough to cut years off galvanized hardware.

Idalia made Cat 3 landfall in the Florida Big Bend and tracked across south Georgia; the NHC report records 2-4 feet of storm-surge inundation above ground level along the Georgia coast, Glynn County included. Mary Ross Waterfront Park and the Bay Street Marina blocks took surge water; downtown Brunswick saw scattered shingle uplift and skylight failures on commercial flat roofs that hadn't been re-sealed in a decade.

Roofing takeaway: Idalia drove home that flat-roof penetration sealing has to be re-inspected on a 5-year cycle in the FEMA AE/VE footprint — not whenever the owner finally calls.

Helene's Cat 4 Florida Big Bend landfall sent devastating tree damage across south Georgia. Glynn County took oak and pine snapping that closed several Brunswick neighborhoods for days; the Sidney Lanier Bridge stayed open but I-95 north toward Savannah saw rolling closures during evac.

Roofing takeaway: Helene proved that hurricane straps and ring-shank nailing earn their cost back the first time a mature live oak comes down across the deck.
