## 01 · Answer — Direct Answer

After a storm, inspect from the ground first, then the attic for daylight or wet insulation. Document everything with date-stamped photos before any repair. File an insurance claim within 30 days for wind or hail damage.

## 02 · Answer — Decision Frame

Storm damage assessment has two distinct objectives that homeowners conflate: documenting damage for the insurance claim, and identifying repairs to prevent further loss. These run on different timelines and require different evidence. The claim window is short (often 30–60 days) and requires date-stamped, location-stamped photos taken before any repair. Mitigation is immediate and requires action — tarping, water removal, electrical safety — but must be photographed first. The most expensive mistake is repairing visible damage before an adjuster inspects, which routinely results in claim denial on the grounds that damage cannot be verified. The second is relying solely on the insurance adjuster's inspection; adjuster-only inspections miss 30–40% of hail and wind damage on average. The third is failing to document pre-storm roof condition, which makes it impossible to prove that new damage is storm-related rather than pre-existing wear.

## 03 · Decision Rules — Decision Rules

- **IF** Hail size ≥ 1 inch — **THEN** File insurance claim — damage is likely even if invisible
- **IF** Wind > 60 mph in region — **THEN** Inspect within 7 days
- **IF** Active leak — **THEN** Tarp and call emergency roofer first
- **IF** Tree limb on roof — **THEN** Do not remove yourself — structural risk
- **IF** Power lines down near roof — **THEN** Do not approach; contact utility first
- **IF** Ceiling stain appears after storm — **THEN** Photograph from below and attic; do not patch drywall before adjuster inspects
- **IF** Sewer vent or chimney flashing displaced — **THEN** High leak risk even without visible shingle damage — inspect and document
- **IF** Neighbor roofs are being replaced after same storm — **THEN** Strong indicator of area-wide damage — file claim and get independent inspection

## 04 · Decision Rules — Modifiers, Exceptions, and Overrides

- **IF** Hail stones ≥ 1 inch reported in your zip code — **THEN** File claim even if no visible damage — bruising is often invisible from ground
- **IF** Wind gusts exceeded 60 mph in your area per NWS — **THEN** Schedule inspection within 7 days; lifted shingles may not have detached yet
- **IF** Tree limb is on the roof — **THEN** Do not remove yourself — structural risk and disturbance can void claim
- **IF** Power lines are down near the roof — **THEN** Do not approach; contact utility first
- **IF** Adjuster denies hail damage you can document — **THEN** Request supplemental inspection with a roofer present; appeal in writing
- **IF** Roof is over 20 years old — **THEN** Confirm RCV vs ACV before accepting settlement — ACV payouts on old roofs often net 30–60% of cost
- **IF** Storm date is approaching policy claim window expiration — **THEN** File a placeholder claim immediately; supplemental documentation can follow
- **IF** Homeowner has cosmetic exclusion endorsement — **THEN** Hail damage that does not break the seal or penetrate may be denied — request detailed denial in writing
- **IF** Mortgagee is listed as loss payee — **THEN** Claim check may be payable to lender; contact them early to avoid disbursement delays
- **IF** Prior claim exists on same roof within 5 years — **THEN** Insurer may apply depreciation more aggressively; independent appraisal may be necessary

## 05 · Decision Rules — Scenario Decision Tree

- **IF** 1.25" hail + 12-year asphalt roof + dented gutters and AC fins — **THEN** Strong claim; expect full replacement approval with roofer-backed documentation
- **IF** Wind 75 mph + visible lifted shingles on windward slope — **THEN** File claim; document creasing under shingle tabs; expect partial or full approval
- **IF** Tornado touchdown within 1 mile, no visible damage — **THEN** Inspect attic for shifted decking and re-tighten any displaced shingles; document baseline
- **IF** Ice storm + sagging gutters + interior wall stains — **THEN** Ice dam damage — covered if from sudden weather event; document immediately with temperature records
- **IF** Storm 45 days ago + just noticed ceiling stain — **THEN** File immediately with weather records; late filing is often grounds for denial but not automatically barred
- **IF** Hail with stones < 1" and no visible damage — **THEN** Document weather event and roof condition for future baseline; do not file unless damage emerges later
- **IF** Multiple homes in neighborhood filing claims for same storm — **THEN** Strong corroborating evidence — file and reference nearby approved claims if challenged
- **IF** Drone inspection reveals soft bruising not visible from ground — **THEN** Critical evidence — request roofer present at adjuster inspection to demonstrate damage in person
- **IF** Flat roof (TPO/EPDM) after 2-inch hail — **THEN** Seams and membrane are vulnerable — inspect for pinholes and seam separation; claim may require thermal imaging proof
- **IF** Metal roof after 1.5-inch hail with no visible denting — **THEN** Check coating integrity and fastener torque; latent damage may not show for 2–3 years
- **IF** Clay tile roof after wind 70+ mph with no broken tiles visible — **THEN** Inspect ridge and hip tiles, under-eave courses, and mortar bedding; wind uplift is often hidden

## 06 · Decision Rules — Contractor Verification Rules (Universal)

- **IF** Contractor lacks state license number on quote — **THEN** Reject — non-negotiable
- **IF** No proof of general liability + workers' comp insurance — **THEN** Reject
- **IF** Manufacturer-certified for the specific material proposed — **THEN** Strongly prefer
- **IF** Demands full payment up front — **THEN** Reject — standard is 10–33% deposit
- **IF** Quote omits underlayment brand, nail count, or warranty length — **THEN** Request itemized rewrite

## 07 · Decision Rules — Insurance Deductible Decision Rule

- **IF** Repair cost < 1.5× deductible — **THEN** Pay out of pocket — claim raises premium
- **IF** Repair cost 1.5–3× deductible — **THEN** File only if damage is sudden + documented
- **IF** Repair cost > 3× deductible — **THEN** File the claim
- **IF** Roof age > 20 years — **THEN** Confirm RCV vs ACV before filing

## 08 · Comparison — Storm Type Severity Matrix

| Storm Type | Immediate Damage | Hidden Damage | Claim Difficulty | Winner |
| --- | --- | --- | --- | --- |
| Hail (1–2 inches) | Moderate | High | Moderate | Highest hidden damage risk |
| Wind 60–80 mph | Moderate | Moderate | Low | Easiest to document and claim |
| Wind 80+ mph / Tornado | Severe | High | Moderate | Most visible damage; structural risk |
| Heavy rain / flash flood | Low | High | High | Hardest to attribute to storm vs. pre-existing |
| Ice dam / snow load | Moderate | High | High | Insurers often dispute sudden vs. maintenance cause |
| Debris / tree impact | Severe | Moderate | Low | Clear causation; easiest claim approval |

## 09 · Diagnosis — Damage Indicators by Storm Type

1. **Hail** _(After ≥1" hail)_ — Circular bruises, mat exposure, dented vents and gutters. Soft hail bruises may show no granule loss for weeks.
2. **Wind (60+ mph)** _(Storm-driven)_ — Lifted, creased, or missing shingles on the windward slope. Ridge caps and starter strips are first to fail.
3. **Heavy rain** _(Common)_ — Stains on attic decking, soaked insulation. May reveal pre-existing leaks that storm exposure opened.
4. **Snow or ice** _(Winter)_ — Ice dam icicles, sagging gutters, interior wall stains. Ice dam damage is often covered as sudden weather event.
5. **Debris impact** _(Less common)_ — Punctures, broken tiles, displaced flashing. Even small branches can crack clay or slate tiles.
6. **Lightning strike** _(Rare)_ — Burn holes, shattered concrete tiles, melted synthetic underlayment. Often accompanied by electrical system damage.
7. **Tornado or microburst** _(Rare but severe)_ — Widespread shingle loss, shifted decking, compromised structural connections. Full structural assessment required.

## 10 · Diagnosis — Damage Patterns Adjusters Miss

1. **Soft hail bruises (no granule loss yet)** _(Common miss)_ — Detectable by touch and chalk-testing; not always visible in photos. Become leaks in 1–3 years.
2. **Creased shingles from wind lift** _(Common miss)_ — Shingle appears in place but seal is broken — fails in next storm. Requires lifting the tab to see crease.
3. **Displaced ridge caps** _(Common miss)_ — Often only visible from above; ground inspection misses 60%+ of these.
4. **Cracked vent boots from hail** _(Common miss)_ — Becomes a leak source within 6–18 months. Boots are cheap to replace but expensive if water damage spreads.
5. **Bruising on accessories (gutters, AC, downspouts)** _(Confirmatory evidence)_ — Used to prove hail size reached the property even when shingles look intact.
6. **Granule accumulation in downspouts post-storm** _(Quantitative evidence)_ — Sudden granule deposits after a storm are a documented hail indicator. Photograph the piles.
7. **Lifted starter strip along eaves** _(Frequent miss)_ — Starter strips are hidden by the first course of shingles; wind can detach them without lifting visible tabs.
8. **Damaged cricket or saddle behind chimney** _(Frequent miss)_ — High-leak area that requires close inspection; often excluded from adjuster walk-around.

## 11 · Diagnosis — What Most Homeowners Get Wrong

1. **Misconception: 'No leak = no damage'** _(Universal)_ — Reality: hail bruising and wind creasing fail months to years after the storm. By then, the claim window has closed.
2. **Misconception: 'The adjuster is impartial'** _(Common)_ — Reality: the adjuster works for the insurer. Always have an independent roofer present at inspection.
3. **Misconception: 'I should fix the leak first, file later'** _(Common)_ — Reality: repairs before inspection routinely cause claim denial. Photograph thoroughly, then tarp.
4. **Misconception: 'Filing a claim raises my premium even if I don't get paid'** _(Partially true)_ — Reality: filing a closed/no-payout claim does affect renewal in some states. Verify with your agent before withdrawing or filing.
5. **Misconception: 'I have years to file'** _(Common)_ — Reality: most policies require notice within 30–60 days of the loss event. Some states allow 1–2 years, but policy language governs.
6. **Misconception: 'My roof is too new to be damaged'** _(Common)_ — Reality: even 1-year-old shingles can be bruised by 1.5-inch hail. Newness does not mean immunity.

## 12 · Diagnosis — Pre-Existing Conditions That Complicate Claims

1. **Granule loss from normal aging misattributed to hail** _(Common dispute)_ — Aging granule loss is diffuse and uniform; hail granule loss is circular and localized. Independent roofer can distinguish.
2. **Prior repairs with mismatched shingles** _(Common dispute)_ — Insurer may argue storm did not cause the damage being claimed; document all prior repairs separately.
3. **Second-layer roof (overlay)** _(Frequent complication)_ — Many policies exclude or limit coverage on overlays; inspect policy language before filing.
4. **Known algae or moss prior to storm** _(Occasional dispute)_ — Insurer may attribute lifted shingles to organic growth rather than wind; clean roof and document pre-storm condition.
5. **Unpermitted prior work** _(Serious risk)_ — Unpermitted additions or re-roofs can void coverage entirely; verify permit history before filing.

## 13 · Diagnosis — Mitigation vs. Documentation — The Timing Trap

1. **Tarping before photographing** _(Common mistake)_ — Emergency tarping is necessary and reimbursable, but photograph the damage first from multiple angles. Tarp hides evidence.
2. **Patching interior drywall before adjuster visit** _(Common mistake)_ — Drywall removal reveals water paths that prove leak origin. Patch after inspection, not before.
3. **Discarding damaged shingles or debris** _(Frequent error)_ — Physical evidence of hail size and wind direction is needed for claim disputes. Bag and store samples.
4. **Delaying claim to 'see if it gets worse'** _(Frequent error)_ — Claim windows are strict. File promptly and supplement later if new damage appears within the claim period.
5. **Accepting first estimate without line-item review** _(Common mistake)_ — Insurer estimates often omit code upgrades, full decking replacement, or matching shingles on undamaged slopes.
6. **Failing to document pre-storm condition** _(Universal gap)_ — Without baseline photos, insurer can argue all damage is wear-and-tear. Annual roof photos are free insurance.

## 14 · Failure Modes — Storm Assessment Failure Modes

### 01 · Undocumented pre-storm baseline

- **Root Cause:** Homeowner has no timestamped photos of the roof from BEFORE the storm, so the adjuster cannot distinguish storm hits from pre-existing wear-and-tear and defaults to the latter.
- **Detection Signal:** No prior inspection report, no annual gutter-cleaning photos, no real-estate listing photos from the last 5 years, and no drone or smartphone roof shots from a clear day.
- **Consequence:** Adjuster classifies 30–70% of legitimate hail bruises as 'mechanical/wear damage,' reducing the claim payout by $4,000–$15,000 or triggering full denial as wear-and-tear.
- **Prevention / Action:** Capture a baseline today: drone or ladder photos of every slope, ridge, and flashing detail with EXIF timestamps, saved to cloud storage. Repeat every 2 years and immediately before any forecasted severe-weather event.

### 02 · Late claim filing

- **Root Cause:** Homeowner waits to file until an interior leak appears, often 6–18 months after the storm event, exceeding the policy reporting window.
- **Detection Signal:** Storm date is more than 30–365 days in the past (window varies by carrier and state), no contemporaneous photo evidence of damage from within the window, and no prior notice-of-loss filed.
- **Consequence:** Carrier denies the claim on prompt-notice grounds regardless of damage severity; homeowner pays full $15,000–$40,000 replacement out of pocket on damage the policy would have covered if filed in time.
- **Prevention / Action:** File a notice-of-loss within 30 days of any named storm with hail ≥ 1" or wind ≥ 60 mph in the ZIP code, even before damage assessment. Filing notice preserves the claim; you can withdraw if no damage is found.

### 03 · Storm-chaser fraud

- **Root Cause:** Out-of-state crew arrives door-to-door post-storm, offers a 'free inspection,' creates damage with a hammer or chalk-marks to exaggerate findings, and secures an AOB-laden contract before the adjuster arrives.
- **Detection Signal:** Contractor has no local physical address, presses for same-day signature, offers to 'waive your deductible' (insurance fraud in most states), or insists on inspecting alone without the homeowner present.
- **Consequence:** Fraudulent damage triggers full claim denial AND potential insurance-fraud investigation against the homeowner; deductible-waiver schemes are felonies in 40+ states; warranty claims are uncollectible after the crew leaves the state.
- **Prevention / Action:** Never allow solo contractor inspection of the roof. Verify state license, local physical address, and 3+ year regional history before any contract. Refuse any offer to waive, absorb, or rebate the deductible — report it to the state insurance department.

### 04 · Hidden moisture intrusion missed

- **Root Cause:** Inspection focuses on shingle surface only and skips attic-side moisture-meter readings on the underside of the decking, so saturated areas are not documented as part of the claim.
- **Detection Signal:** Inspection report has no moisture-meter readings, no attic-side photos with date stamps, and damage is described only in terms of visible exterior shingle hits.
- **Consequence:** Saturated decking continues to rot under the new shingles in 6–18 months; mold remediation ($3,000–$15,000) and decking re-replacement ($2,000–$8,000) become out-of-pocket because they were not in the original scope.
- **Prevention / Action:** Require attic-side moisture-meter readings at every slope as part of the inspection report, with photographs of the meter at the reading point. Any reading > 18% moisture content must be in the claim scope as decking replacement.

### 05 · Solo adjuster inspection

- **Root Cause:** Homeowner allows the insurance adjuster to inspect the roof alone, without an independent roofer present, trusting the adjuster's training and impartiality.
- **Detection Signal:** No independent roofer scheduled to attend the adjuster meeting, no homeowner spreadsheet of pre-identified damage zones to walk, and the adjuster spends < 20 minutes on roof.
- **Consequence:** Industry data shows solo adjuster inspections under-count damage 30–40% of the time; ridge caps, vent boots, starter strips, and chimney cricket damage are routinely missed, costing the homeowner $3,000–$12,000 in unrecognized scope.
- **Prevention / Action:** Schedule an independent licensed roofer to attend the adjuster's inspection. Provide both parties with a written list of pre-identified damage zones. Request supplemental claims in writing for any items missed.

### 06 · ACV-vs-RCV settlement misread

- **Root Cause:** Homeowner accepts the first settlement check without confirming whether it is Actual Cash Value (depreciated) or Replacement Cost Value (full new), and whether the recoverable-depreciation portion is being withheld pending completion.
- **Detection Signal:** Settlement letter does not state 'ACV' or 'RCV' explicitly, depreciation amount is not itemized, and there is no instruction for recovering withheld depreciation after work is complete.
- **Consequence:** Homeowner deposits an ACV check assuming it is the full payout, signs a release, then discovers the remaining 30–60% of replacement cost is owed out of pocket; recoverable depreciation is forfeited if not claimed within the policy window (typically 180 days–2 years).
- **Prevention / Action:** Before depositing any settlement check, get written confirmation of ACV vs RCV, the depreciation amount, and the recoverable-depreciation deadline. Complete the work and submit the final invoice to recover the depreciation portion before the deadline.

## 15 · Cost — Emergency Mitigation & Inspection Costs

- **Low** — $200–$500 (Emergency tarping for small leak area; ground-level inspection by local roofer)
- **Typical** — $500–$1,500 (Full roof tarp, attic moisture check, independent hail/wind inspection with written report)
- **High** — $1,500–$4,000 (Structural tarp after tree impact, engineered temporary repair, thermal imaging inspection for hidden moisture)

**Cost drivers:** Storm severity and area affected — larger tarps require more labor and materials, Roof pitch and height — steep or multi-story roofs increase tarping cost 30–60%, After-hours or weekend emergency call — adds 50–100% premium, Type of tarping needed — weighted tarp vs. nailed batten strip vs. full membrane, Independent inspection with written report — adjuster-grade documentation costs more but pays off in claim recovery, Thermal imaging or drone survey — detects hidden damage standard inspection misses, Tree removal requirement — arborist or crane adds $500–$2,500 depending on limb size, Interior water mitigation — water extraction, dehumidifiers, and mold prevention add $500–$3,000, Engineering assessment for structural impact — required after tree falls or tornado-level wind; $400–$1,200, Claim documentation package — photo logs, weather reports, roofer reports, and legal review if disputed

## 16 · Risk — Risk Thresholds

- **Low** — Storm passed, no visible damage, no leak indicators → Inspect gutters and downspouts for granule deposits; photograph roof baseline for future comparison
- **Moderate** — Granule loss in gutters after hail or lifted shingle tabs visible → Document and inspect within 14 days; consider independent roofer assessment before filing
- **High** — Missing shingles, dented vents, or displaced flashing visible from ground → Tarp if leak risk; schedule roofer inspection within 7 days; prepare claim documentation
- **Critical** — Daylight through decking, structural sag, active interior water intrusion, or tree impact → Emergency tarp immediately; do not enter attic if ceiling is sagging; structural review before any repair

## 17 · Recommendation — Recommendation

> Order an independent roofer inspection — not just the insurance adjuster's. Claim-experienced roofers identify 30–40% more damage on average. Document the roof condition before any repair, and never sign an assignment of benefits (AOB) without legal review.

## 18 · Recommendation — Documentation & Evidence Checklist

> 1. Photograph the roof from all four sides and the attic before any tarp or repair. 2. Save local weather reports (NOAA, Weather Underground) for the storm date. 3. Photograph hail stones next to a ruler or coin. 4. Document dented accessories: gutters, downspouts, AC condenser fins, window screens, garage door. 5. Collect neighbor statements if they had damage from the same storm. 6. Request a written inspection report from an independent roofer, not just an estimate. 7. Keep all receipts for emergency mitigation (tarping, water extraction) — these are reimbursable under most policies. 8. Email all documentation to yourself for date-stamped backup. 9. Do not discard damaged shingles or materials before adjuster inspection. 10. Record the adjuster's name, inspection date, and all verbal commitments in writing afterward.

## 19 · Recommendation — Insurance Claim Timeline & Adjuster Tactics

> Day 1–3: Photograph everything from ground and attic. Save NOAA weather data. Contact your insurance agent to confirm claim window and coverage type (RCV vs ACV). Day 3–7: File the claim. Request an independent roofer inspection — do not rely on adjuster-only. Day 7–14: Attend adjuster inspection with your roofer present. Ask for a copy of the adjuster's scope of loss. Day 14–30: If settlement is low, request a supplemental inspection. Document any new damage discovered. Day 30–60: If denied, appeal in writing with roofer documentation. Consider public adjuster or appraisal clause. Common adjuster tactics: (1) Claiming damage is 'cosmetic' — request denial in writing and get roofer rebuttal. (2) Offering ACV on a policy that includes RCV — verify policy language. (3) Excluding code-upgrade coverage — verify ordinance/law coverage limits. (4) Rushing settlement before latent damage appears — do not sign release until full inspection is complete.

## 20 · Recommendation — Final Decision Recap

> After any storm with hail ≥ 1" or wind ≥ 60 mph: document from the ground, then attic, with date-stamped photos before any repair. File the claim within 30 days even if damage looks minor. Hire an independent roofer to attend the adjuster's inspection — solo adjuster inspections under-count damage 30–40% of the time. Confirm RCV vs ACV in writing before accepting settlement, especially on roofs over 15 years. Do not sign an assignment of benefits. Keep all mitigation receipts. If denied, appeal in writing with supplemental roofer documentation.

## Related questions

### How do I know if storm damage requires a claim?

File a claim if you see hail bruising, lifted or missing shingles, granule loss in gutters, or any active leak after a storm.

### How long do I have to file a roof storm-damage claim?

Most policies require filing within 1 year of the storm event; some require notice within 30–60 days. Document damage immediately.

### Can I inspect storm damage myself?

Do a ground-level inspection only. Climbing on a storm-damaged roof is unsafe — hire a licensed inspector for the close-up assessment.

### What wind speed damages a roof?

Sustained winds above 50 mph can lift shingles; 70+ mph or any tornado-spawning storm typically causes claim-eligible damage.
