Types of storm damage we repair
Storm damage falls into four primary categories with distinct damage signatures and repair approaches.
Wind Damage
Lifted or missing shingles, displaced flashing, blown-off ridge caps, exposed underlayment. Failure threshold begins at 50+ mph sustained winds for older shingles (Class D, 90 mph rated). Class H 130-mph rated shingles withstand much higher speeds before failure.
Hail Damage
Granule loss bruises, broken or cracked shingle tabs, dents on metal flashing and vents. Often invisible from ground level. Cumulative damage from multiple smaller events is common in hail-belt regions.
Tree / Limb Impact
Direct structural damage from falling branches or trees. Penetration of the deck, displacement of multiple shingle courses, sometimes framing damage. Almost always requires emergency response before permanent repair.
Ice / Snow Loading
Ice dam meltwater intrusion, snow load deflection of the deck, gutter ice damage. Concentrated in cold-climate regions Dec-Mar. Some damage appears weeks after the snow event when meltwater infiltration becomes visible inside.
Storm-Event Correlation
For insurance documentation, every storm damage repair includes correlation to a specific NOAA-documented weather event when one applies. The event date, wind speed or hail size, and proximity to the property are documented — this evidence converts ambiguous damage into a clearly storm-correlated claim.
Multi-Event Damage
Damage from one event compounds damage from a previous event in roughly 30% of inspections. We document each contributing event separately so the carrier can apportion the claim correctly rather than rejecting it as ambiguous causation.
Wind damage signature and assessment
Wind damage occurs when shingle tabs lift above the breakaway force of the factory adhesive strip. The tab does not always tear free — it often resets into approximately the original position with broken adhesive bonds. The visible roof appears intact; the underlayment is exposed, and water intrusion follows during the next rain event.
Wind speed thresholds and shingle ratings
- Class D (90 mph): ASTM D7158 rating common on pre-2010 installations. Failures begin at 50-65 mph sustained winds.
- Class G (120 mph): Standard for most current architectural shingles. Failures begin at 75-90 mph.
- Class H (130 mph): Premium architectural shingles. Failures begin at 100+ mph; designed for hurricane corridor exposure.
- Class F (110 mph): Less common interim rating.
How we assess wind damage
- Visual roof survey identifying lifted, displaced, or missing tabs. Drone overhead survey on steep-pitch roofs.
- Tab adhesion testing in sample areas — gentle lift force applied to verify whether the adhesive bond is intact.
- Underlayment inspection where tabs are lifted to check for water staining or damage.
- Ridge cap inspection — wind-displaced ridge caps are common and create high-volume leak paths.
- Flashing inspection at sidewalls, headwalls, and chimneys — wind events frequently displace step flashing without visible roof damage.
- NOAA weather event correlation — if a specific named event correlates with the damage timeline, we attach the NOAA Storm Events Database record to the claim documentation.
Hail damage signature and assessment
Hail damage is the most under-reported storm damage type because it is largely invisible from ground level. Hailstones strike the shingle surface, fracturing the asphalt mat below and dislodging granules in a circular bruise pattern. The shingle continues to function for months or years before the underlayment becomes exposed and active leaking begins.
Hail size thresholds
| Hail Size | Shingle Damage | Other Damage |
|---|---|---|
| 0.75" (penny) | Minimal damage to standard shingles | Vinyl siding cosmetic, screen damage |
| 1.0" (quarter) | Bruising and granule loss on 3-tab shingles | Vehicle dents, vinyl siding cracks |
| 1.25" (half-dollar) | Bruising on architectural shingles, broken tabs on 3-tab | Window damage possible |
| 1.5" (ping pong ball) | Damage on most asphalt shingles, dents in metal flashing | Significant vehicle damage, window breakage |
| 2.0" (golf ball) | Damage to all asphalt roofing, denting on metal roofs, tile cracks possible | Major property damage |
| 2.5"+ (tennis ball+) | Damage to nearly all roofing materials including slate and concrete tile | Catastrophic property damage |
Hail damage indicators on shingles
- Granule loss bruises: Circular dark spots roughly 0.5-2 inches in diameter where granules have been displaced.
- Broken tabs: Visible cracks running across shingle tabs, often in a curved pattern matching the hailstone impact.
- Mat fractures: Visible only on close inspection — fine cracks in the asphalt mat below the granule layer, requiring chalk-test verification.
- Metal flashing dents: Round impact dents on metal counter-flashing, vent caps, or roof jacks. The most reliable hail indicator because metal does not heal over time.
Tree limb impact and structural damage
Tree limbs penetrating the roof deck create both a structural and water entry emergency. Repair scope depends on the limb size, impact angle, and damage extent.
Damage scope by impact severity
- Minor limb impact (under 6" diameter): Localized shingle damage, possible underlayment tear, no deck penetration. Repair: shingle replacement, underlayment patch. Cost: $700-$1,400.
- Moderate impact (6"-10" diameter limb): Deck penetration, multiple shingle courses displaced, possible rafter contact. Repair: deck patch (1/2" plywood section), full underlayment, shingle replacement, possible rafter sister-bracing. Cost: $2,200-$5,500.
- Major impact (10"+ diameter or full tree): Significant deck and framing damage, possible truss failure, often partial roof structure collapse. Requires structural engineer assessment, framing replacement, full deck and roof system replacement on affected slopes. Cost: $8,500-$45,000+ depending on extent.
Insurance specifics for tree damage
Tree damage to a roof is typically covered as a Falling Object loss under most U.S. homeowner policies. Two important nuances: (1) damage from your own tree is covered the same as damage from a neighbor tree — coverage applies to the property damage, not the tree origin; (2) tree removal cost is partially covered (often capped at $500-$1,000) when the tree has caused property damage, but uncovered when the tree fell harmlessly.
Ice loading and snow damage
Ice and snow damage is concentrated in cold-climate regions December through March. Three damage modes:
Ice dam meltwater intrusion
Heat escape from the attic warms the upper roof slope, melting snow that refreezes at the cold eave. Meltwater pools behind the dam and migrates backwards under shingle courses, bypassing the water-shedding overlap pattern. Repair scope varies; eave underlayment replacement typically runs $1,200-$3,500 per affected slope.
Snow load structural deflection
Heavy wet snow can produce loads of 20-50 lb per square foot on the roof deck. Older 2x6 framing or compromised trusses can deflect or fail under sustained heavy load. Visible signs include sagging ridge lines, interior door frames going out of square, and audible cracking sounds during heavy loading.
Gutter ice damage
Frozen gutters and downspouts cause meltwater to overflow and back under the eave. The damage path differs from a true ice dam — water enters at the soffit/fascia rather than under the shingle course. Repair includes gutter clearing, sometimes downspout heat cable installation, and minor soffit/fascia repair as needed.
The storm-claim documentation package
Insurance carriers approve approximately 70% of properly-documented storm damage claims, based on industry data published by NAIC. The documentation package we provide with every storm damage repair includes:
- Pre-repair photo set — wide-angle and close-up views of all damage areas, with EXIF timestamp data preserved.
- Damage signature documentation — chalk-circle marking of hail bruise patterns, tab-lift photographs of wind damage, structural displacement of impact damage.
- FLIR thermal images where moisture has migrated into the building envelope, in original radiometric format.
- Drone overhead imagery for steep-pitch roofs, including thermal overlay where available.
- NOAA Storm Events Database extract — the specific weather event record corresponding to the damage timeline, including hail size, wind speed, event ID, and proximity to property.
- Written contractor statement identifying the proximate cause, the specific failure points, and the timeline.
- Xactimate-format itemized estimate with line-item pricing matching the carrier database for your zip code.
- Symbility-format estimate on request (State Farm, Allstate, several regionals).
Claim timeline and process
| Stage | Typical Timeline |
|---|---|
| Storm event → contractor inspection | 3-14 days (recommended; longer delays weaken event correlation) |
| Inspection → claim filing with carrier | Same day after inspection; documentation handed to homeowner |
| Claim filing → adjuster contact | 1-7 days for most carriers; 14+ days during high-claim periods after major events |
| Adjuster on-site → coverage decision | 7-21 days from initial contact |
| Coverage approved → first check (ACV portion) | 5-14 days |
| Repair completion → recoverable depreciation check (RCV policies) | 14-30 days after submitted documentation |
Total claim cycle: approximately 30-90 days from initial event to final settlement check. Repair work can begin once the ACV check is received and the carrier has signed off on the scope.
Avoiding storm chasers
The standard storm-chaser pitch involves an aggressive replacement quote, pressure to sign immediately, and offers to "waive your deductible" — which is illegal insurance fraud in most U.S. states. Roof Leak Repair 24/7 does not knock on doors. We do not waive deductibles. We do not pressure-quote.
How to verify any roofing contractor after a storm
- Verify the state contractor license through the appropriate state authority.
- Verify general liability insurance certificate ($1M minimum) and workers compensation coverage. Request the certificate of insurance directly from the contractor insurance carrier.
- Look up the business at BBB and check for complaints, particularly recent complaints from the past 12 months.
- Search the business name plus "complaints" or "scam" — established storm chaser operators often have a public trail of issues.
- Never sign a contract that includes assignment of insurance benefits to the contractor without legal review. AOB (Assignment of Benefits) clauses can transfer your claim rights to the contractor and have been the subject of significant fraud in storm-affected regions.
Frequently asked questions
How do I know if my roof has storm damage?
Visual indicators include missing or lifted shingles, granule loss patches, dents on metal flashing or vents, broken or cracked shingle tabs, and damaged or displaced ridge caps. Active leaking is the most reliable indicator. Hail damage can be invisible from ground level — bruising and granule loss often require close inspection or drone overhead survey to identify.
How long after a storm do I have to file a claim?
Most U.S. homeowner policies require notice of loss within 60-365 days depending on the carrier. State Farm, Allstate, and most national carriers allow up to one year. Filing promptly is recommended — the longer the delay between event and inspection, the harder it becomes to document the storm-event correlation that supports the claim.
Can hail damage a roof if the hail is not large?
Yes. Hail of 1.0" diameter or larger can damage standard 3-tab asphalt shingles. Hail of 1.5" can damage architectural shingles. Hail of 2.0" damages most roofing materials. The damage is often cumulative — repeated hail events of moderate size produce the same total damage as a single large-hail event.
Should I file a storm damage claim?
The decision depends on three factors: total damage estimate, your deductible amount, and your claim history. Damage exceeding 2-3x the deductible typically justifies filing. Damage near or below the deductible is paid out of pocket. Claim history matters because too many claims in a short window can affect renewal terms.
What is recoverable depreciation?
Recoverable depreciation is the portion of a Replacement Cost Value (RCV) policy claim that the carrier holds back until repair work is complete. Initial check pays the depreciated value (ACV). After the repair is finished and documentation is submitted, the held-back depreciation is paid as a second check. ACV-only policies do not include recoverable depreciation.
Will filing a storm claim raise my premium?
A single weather-related claim typically does not raise premiums on most U.S. policies — weather events are considered non-controllable losses. Multiple claims in a 3-5 year window can affect premiums or renewal terms. Verify with your insurance agent before filing if you have had recent claims.
