Wind Damage Insurance Appraisal
Marshall Services LLC provides independent, impartial wind damage insurance appraisals for residential and commercial property throughout Texas and Oklahoma. Straight-line winds, derechos, and severe thunderstorm gusts routinely damage roofs, siding, and building envelopes across North Texas and Oklahoma, while the Gulf Coast — Galveston, the Coastal Bend, and the Rio Grande Valley — faces windstorm risk often covered through the Texas Windstorm Insurance Association (TWIA). IAUA CPAU-certified appraiser Marshall Smith uses Xactimate estimating software, FAA Part 107 drone inspections, and construction expertise to document the full scope of a wind loss — shingle uplift and creasing, broken adhesive seals, ridge caps and flashing, roof decking, commercial membrane uplift, siding and gutter blow-off, interior water intrusion through wind-created openings, fences and outbuildings. Wind disputes turn on causation, not impact counts: wind-versus-wear-and-tear denials, spot repair versus full-slope replacement once seals break, ACV and depreciation, and excluded interior damage. We resolve them by mapping the directional damage pattern against the storm's recorded wind field, with drone imagery of steep and high roofs. The appraisal process determines the amount of a covered wind loss, not whether the loss is covered, far faster than litigation. Serving policyholders and insurers across Texas, Oklahoma, Louisiana, Colorado, and California, including TWIA coastal windstorm valuation disputes with their strict deadlines. When a wind-created opening lets rain into the building, the moisture scope is set out on our water damage insurance appraisal for Texas property page. The Certified Property Appraiser & Umpire designation from the IAUA requires certification coursework, an examination, adherence to the association's code of ethics, and periodic recertification. Listed on the Texas Department of Insurance roster of appraisal umpires — the roster TDI draws on to appoint an umpire for Texas Windstorm Insurance Association (TWIA) claims when the two sides cannot agree on one — and Marshall Smith holds an active Texas Department of Insurance license number 1642160. Placement on the roster is not an endorsement or certification by the Texas Department of Insurance.
Frequently Asked Questions
How do I know if my wind damage claim was undervalued?
Common signs that a wind claim estimate may not reflect the full amount of loss include:
• Spot repairs were scoped when entire roof slopes were damaged • Creased, lifted, or unsealed shingles were dismissed as cosmetic • Damaged roof decking, flashing, or ridge caps were left out • Siding, fascia, soffit, and gutters were only partially accounted for • Interior water damage from wind-created openings was excluded • Fences, outbuildings, and detached structures were overlooked • Pricing used was below current local labor and material rates
If the gap between the actual repair scope and the insurer's estimate is significant, the appraisal process provides an impartial way to determine the accurate amount of loss.
Can I demand appraisal for a wind damage claim?
Yes. If your policy contains an appraisal clause — most residential and commercial property policies do — either party may invoke it when there is a disagreement over the amount of a covered wind loss. The demand is submitted in writing to the insurer. Important distinction: the appraisal process determines the amount of loss, not whether the loss is covered. Coverage and liability questions remain with the insurer and, if necessary, the courts.
What is the difference between wind damage and hail damage on a claim?
Wind and hail frequently strike in the same storm, but they damage property differently. Wind lifts, creases, and tears shingles, breaks adhesive seals, and peels back siding, fascia, and roofing membranes — sometimes creating openings that let rain into the structure. Hail causes impact damage: bruising, fractures, and granule loss. Because the two are often intertwined in one loss, a thorough appraisal documents both so the full covered damage is captured — not just the most obvious portion.
Does the appraisal process apply to TWIA windstorm claims?
Texas Windstorm Insurance Association (TWIA) policies for coastal properties include their own dispute provisions with strict deadlines, so it is important to act quickly after receiving a claim decision you disagree with. Marshall Services serves as an independent appraiser for windstorm valuation disputes, documenting the full scope of wind damage with Xactimate. If you have a coastal windstorm claim, contact us early so the required timelines can be met.
What does a wind damage appraisal cost?
Each party pays for its own appraiser, and if a neutral umpire is needed (only in cases where the two appraisers cannot agree), that cost is shared equally. Appraiser fees generally range from $1,000 to $5,000 depending on the size and complexity of the property and the loss — a fraction of the cost and time of litigation.
How long does a wind damage appraisal take?
Most wind damage appraisals resolve in a matter of weeks to a few months — substantially faster than litigation, which can take years. The timeline depends on how quickly the insurer appoints its appraiser, the size of the loss, and whether an umpire is needed. The majority of cases settle when the two appraisers exchange well-documented estimates.
My insurer says my roof damage is wear-and-tear, not wind. Can appraisal help?
Causation — wind versus wear-and-tear — is the most common wind dispute, and it is important to understand what appraisal does and does not decide. Appraisal determines the amount of a covered loss; a pure coverage denial remains with the insurer and, if needed, the courts. That said, the physical evidence that distinguishes wind from age is exactly what a thorough appraisal documents: wind creases shingles at the sealant line and snaps unsealed tabs in a directional pattern that matches the storm's wind field, unlike the uniform brittleness of an aged roof. Correlating that pattern with recorded wind speeds on the date of loss is often what resolves the disagreement.
The insurer only approved a few shingles, but my roofer says the whole slope is compromised. Why?
Wind breaks the adhesive seals that bond shingles together. Once those seals are broken across a slope, the shingles no longer stay bonded — the slope is compromised even where nothing is visibly missing. Insurers frequently scope only the missing pieces. An independent appraisal documents the extent of seal failure so the scope reflects repair or replacement of the full affected slope or system, not just a cosmetic patch of the obvious gaps.
Does the appraisal process apply to hurricane and coastal windstorm claims?
Yes. Coastal wind losses — including TWIA windstorm claims and the wind portion of hurricane and named-storm losses — can go through appraisal when there is a dispute over the amount of a covered loss. Coastal claims add wrinkles inland claims rarely see: named-storm or hurricane deductibles, engineered wind-uplift requirements, and wind-versus-flood causation. Because TWIA and coastal policies carry strict dispute deadlines, it is important to act quickly. Marshall Services documents the full scope of coastal wind damage with Xactimate and FAA Part 107 drone imagery for homeowners, associations, and commercial owners along the Texas coast.
Is a wind damage appraisal award binding?
Yes, if your policy contains an appraisal clause, an award signed by any two of the three participants is generally binding on the amount of loss. Each side selects its own appraiser, and a neutral umpire breaks a tie when the appraisers cannot agree. Appraisal does not decide whether damage is covered. After the award, the carrier applies the policy's deductible and other terms.
Do you handle wind damage appraisals outside Texas?
Yes, Marshall Services handles wind damage appraisals in Texas, Louisiana, Oklahoma, Colorado, and California. Whether appraisal is available depends on the language of your property policy and the nature of the disagreement. If the policy contains an appraisal clause, the process generally addresses the amount of loss rather than deciding whether the wind damage is covered.
