Insurance Appraiser & Appraisal Umpire in Houston, Texas

When Houston Property Damage Happens — and How It Gets Argued

Houston's disputed-claim calendar has a distinct shape. Named-storm season runs June through November, with the greatest exposure in August and September when Gulf water is warmest — Harvey, Ike, and Beryl all landed in this window. But the metro also sits inside the spring hail and straight-line-wind corridor that runs March through May, and the May 2024 derecho showed that inland convective wind can shatter high-rise glass and strip roofs far from the coast. Damage patterns follow the peril: coastal and near-bay properties in Clear Lake, Baytown, and Pasadena see wind uplift and wind-driven rain intrusion, while inland communities like Katy, Cypress, and Spring more often present spring hail bruising on shingles and soft metals.

Two factors complicate Houston claims specifically. First, the region's expansive clay soils move with drought and saturation cycles, so foundation-related cracking is frequently raised as a coverage question — was the loss sudden and storm-driven, or long-term earth movement? Second, Gulf humidity accelerates hidden moisture and microbial growth after a wind-created opening, which means the timing and sequence of water intrusion often becomes the central factual dispute rather than the roof damage itself.

The Order of Events in a Houston Appraisal

Appraisal is invoked under the policy's appraisal clause once the parties have reached an impasse on the amount of loss — not coverage. Each side names a competent, independent appraiser; the two appraisers then select an umpire. On a typical residential Houston file, the sequence runs: written demand for appraisal, appraiser appointments confirmed, a joint or independent inspection scheduled, exchange of Xactimate estimates, and an attempt by the two appraisers to agree. Where they agree, they sign an award and the file closes. Where they disagree on specific line items, only those contested items go to the umpire, who resolves them; an award signed by any two of the three is binding on the amount.

Realistic timelines depend on scheduling and roof access, but a straightforward single-family file often resolves in a few weeks to a couple of months — considerably faster than litigation. Commercial and multi-family files with multiple buildings, TPA involvement, or large flat-roof systems run longer. The documents that carry the most weight are dated field photography, moisture-meter and infrared readings, a peril-specific damage narrative, meteorological data placing hail or wind at the address on the loss date, and a line-item Xactimate estimate that matches the observed scope.

The Questions This Page Leaves Open

What is the difference between wind and hail damage on a Houston claim? Wind damage shows as directional lifting, creasing, and displaced or torn material, and is supported by recorded wind-speed data; hail damage presents as randomly distributed bruising, mat fracture, and spatter on soft metals, and is supported by storm-date hail-swath data. Distinguishing the two matters because deductibles and coverage triggers can differ.

What actually gets documented in aggregate Houston disputes? Across recent Gulf-region files, the recurring pattern is the same one that resolves them: thorough field documentation with detailed photo evidence and line-item justification during the appraisal process. In one anonymized wind-damage file handled outside the immediate metro but under a Gulf-coast wind policy, that combination — wind-speed data paired with a structural assessment — was what moved a disagreement over scope to a signed award.

What if my loss involves both wind and flood? These are separate perils under separate coverage, and the appraisal documents the physical evidence — breach points, water lines, moisture gradients — that assigns damage to the correct peril rather than lumping them together.

Drone Documentation and Houston's Controlled Airspace

Much of Harris County sits under controlled airspace. George Bush Intercontinental, William P. Hobby, and Ellington Field each generate airspace shelves that reach across large stretches of the metro, and a drone flight over a damaged roof in Spring, Pasadena, or near Clear Lake often requires LAANC authorization before it can lawfully launch. Marshall Services holds FAA Part 107 certification and files those authorizations as part of the inspection, so aerial documentation of a steep or multi-story roof is captured properly rather than improvised on the day.

This matters more in Houston than in most Texas markets because storm-damaged roofs here are frequently unsafe to walk — saturated decking, brittle mid-summer shingles, and multi-story pitches on many suburban homes. Overhead imagery captures displaced ridge caps, torn field shingles, and flashing separation from angles a ladder cannot reach, and time-stamped drone frames become part of the same dated photographic record that anchors the Xactimate scope.

Preparing Your File Before Appraisal Is Invoked

The strength of an appraisal position is usually decided before the demand is ever sent. Before invoking, it helps to assemble the policy declarations page — this confirms whether a separate named-storm or windstorm deductible applies and how it is calculated as a percentage of dwelling coverage, which is where much of the early confusion on Gulf-coast claims originates. Alongside it, gather the carrier's inspection report and estimate, any repair or mitigation invoices already paid, and every dated photograph taken from the day of loss forward, including phone images homeowners often overlook.

For water and moisture questions, early drying-log entries and any restoration company's moisture readings are valuable, because Houston's humidity means the sequence and timing of intrusion frequently becomes the pivotal factual issue. Having these in hand lets the appraisal begin from a documented baseline rather than a reconstruction, and it shortens the inspection-to-award interval on a straightforward single-family file.

Commercial, Multi-Family, and High-Rise Files

Houston's commercial and multi-family stock introduces variables a single-family roof claim does not. The Energy Corridor, the Galleria area, the Texas Medical Center, and downtown carry large low-slope roof systems — TPO, modified bitumen, and built-up assemblies — where the dispute often centers on whether hail bruising or wind uplift compromised the membrane's integrity versus cosmetic marking. These assessments turn on core samples, seam inspection, and manufacturer repairability standards rather than the shingle-bruise analysis used on residential steep-slope roofs.

The May 2024 derecho demonstrated a second commercial exposure: straight-line convective wind shattered curtain-wall glass on downtown towers far from any coastline, putting glazing, cladding, and interior water damage on the same file as the roof. High-rise and mid-rise glass claims require documenting pressure-driven failure and the path of subsequent water intrusion through the building envelope, floor by floor.

Multi-family properties — garden-style apartment complexes across Katy, Cypress, and Spring, and larger portfolios throughout the metro — carry their own timeline realities. Multiple buildings, separate roof ages, third-party administrator involvement, and unit-by-unit interior scope all extend the appraisal beyond the few-weeks-to-a-couple-of-months range typical of a single home. On these files the discipline that resolves them is consistent with what resolves smaller Gulf-region disputes: thorough field documentation, detailed photographic evidence, and line-item justification carried through the appraisal process. Where the two appraisers agree on most buildings and disagree only on specific structures or line items, those contested items are the ones referred to the umpire, keeping the balance of the award moving.

Who Pays for a Houston Appraisal — and How the Costs Are Shared

A question the process description above raises but does not answer is cost. Under the standard appraisal clause, each party pays the fee of the appraiser it appoints, and the two parties split the umpire's fee and expenses equally. That structure is written into most Texas homeowner and commercial forms, so a policyholder invoking appraisal is generally responsible only for their own appraiser plus half the umpire — not the full panel. Appraisal is a valuation mechanism, not a legal representation arrangement; an independent appraiser is retained to determine the amount of loss impartially, which is a different role from a public adjuster who negotiates a claim for a percentage. On larger commercial and multi-family files, umpire time scales with the number of buildings and the volume of contested line items, which is one more reason the documentation discipline described above shortens the process: the fewer items left in genuine dispute, the less umpire time the parties share.

When the Dispute Is About Cause, Not Just Amount

Appraisal resolves the amount of loss, while coverage — whether a peril is covered at all — remains with the carrier and, if necessary, the courts. In Houston that line blurs more often than in drier markets, because so many losses arrive with a mixed causation question attached. Expansive clay soils, prior roof age, and Gulf humidity all give rise to arguments that some portion of observed damage predates the storm or stems from wear rather than a covered event. Texas panels routinely handle this by segregating the loss: the appraisers and umpire determine the amount attributable to the storm-date peril and set aside what is not, rather than awarding a lump sum. That is why cause-of-loss documentation carries as much weight as scope documentation.

In one anonymized Houston-area file involving a disputed damage classification, the central question was not the repair price but whether the damage was storm-driven at all. The recurring pattern that moved it was the same one that resolves cause disputes generally: clear, dated evidence tying the observed condition to the loss event — field photography, a peril-specific narrative, and meteorological data placing the wind or hail at the address on the claimed date. Where the physical evidence and the storm record line up, the classification argument tends to resolve without escalation.

What Happens After the Award Is Signed

The appraisal award is often treated as the finish line, but on a Houston claim it usually starts the final payment sequence rather than ending it. An award signed by any two of the three panel members is binding as to the amount of loss. The carrier then applies the policy terms to that number — the named-storm or windstorm deductible, any prior payments already issued, and the difference between actual cash value and replacement cost. On a replacement-cost policy, the award typically establishes both the ACV owed now and the recoverable depreciation that becomes payable once repairs are completed and documented, so keeping repair invoices and completion records matters even after the panel has finished its work.

Two Houston-specific points are worth knowing. First, the appraisal award addresses only the perils and property within the appraisal's scope; it does not convert an excluded loss into a covered one, which is why the wind-versus-flood evidence described earlier is assembled before the demand rather than after the award. Second, flood losses under a separate NFIP policy follow their own federal process and do not carry the same appraisal clause found in wind and homeowner forms — so a property struck by both wind and rising water may run a wind appraisal and a separate flood claim on parallel tracks. To discuss how the award stage would apply to your Harris County or Greater Houston loss, call Marshall Services at 972-322-0752.

Choosing and Challenging the Appraisers and Umpire

The appraisal clause requires each side to name a competent and independent appraiser, and on Houston files those two words carry practical weight. Competence generally means demonstrable familiarity with the property type and peril at issue — a low-slope commercial membrane, a multi-story Gulf-coast roof, a wind-driven-rain intrusion path. Independence means no financial stake in the outcome; an appraiser compensated as a percentage of the award is not disinterested, which is one reason the appraiser role and the public-adjuster role cannot be filled by the same arrangement. If a party believes the other side's appraiser is not truly independent, that objection is raised early, before the panel invests inspection time, because a disqualification after the fact can unwind the process.

Umpire selection follows the same standard. The two appraisers are expected to agree on an umpire within a reasonable time; when they cannot, most Texas forms allow either party to ask a court to appoint one. On Harris County commercial and multi-family files, umpire familiarity with core sampling, seam analysis, and manufacturer repairability standards matters as much as general appraisal experience, so the appraisers' short list is usually built around the specific building systems in dispute rather than picked at random.

Ordinance-or-Law and Code Upgrades on Older Houston Roofs

A cost question the process description above does not reach is what happens when repairing storm damage triggers current building code. Much of Houston's inner-loop and near-suburb housing stock predates today's roofing and decking requirements, so a covered reroof can force code-driven work the original assembly never had — re-nailing schedules, decking replacement, drip edge, or full-system requirements once a threshold percentage of the roof is disturbed. Whether the appraisal award includes that work depends on the policy: ordinance-or-law coverage is a separate limit, and where it exists, the code-required scope is a legitimate line item the panel can value. Where it is absent or capped, the panel values the like-kind-and-quality repair and the code delta is handled separately under the policy terms. Bringing the declarations page and any ordinance-or-law endorsement to the table before the demand keeps this from becoming a mid-appraisal surprise.

Debris Impact, Detached Structures, and the Rest of the Property

Houston storms rarely damage only the primary roof. Wind-borne debris and fallen trees drive impact claims on fences, detached garages, patio covers, and screen enclosures — features common across Katy, Cypress, Spring, and the bayfront communities. These items frequently sit under different valuation rules than the dwelling: fences and many detached structures are often settled at actual cash value rather than replacement cost, and detached-structure coverage is usually a percentage sublimit of the dwelling amount. When the interior is affected, sequence again becomes the issue — a tree penetration creates a wind-created opening, and the resulting water and humidity-driven damage tracks back to that breach rather than to rising water.

Across recent Houston-metro files involving non-hail, mixed-scope damage, the recurring dispute was not the repair price of any single item but whether the full range of secondary damage — detached structures, interior finishes, and debris impact — was captured in the original scope at all. In those files the pattern that moved a disagreement toward a signed award was consistent with what resolves Gulf-region disputes generally: comprehensive documentation and expert evaluation that itemizes every affected component, dwelling and appurtenant structures alike, rather than treating the roof as the whole loss. A line-item Xactimate estimate that reflects fences, detached buildings, and interior scope on their correct valuation basis leaves fewer items in genuine dispute — and fewer contested items means less umpire time for the parties to share.

Matching and Uniformity When Only Part of a Houston Roof or Interior Is Damaged

A recurring question the process description above does not reach is what happens when a storm damages only a section of a roof, siding run, or interior finish and the replacement material no longer matches what remains. This is common on Houston claims because so much of the metro's housing stock is a decade or more old, and discontinued shingle lines, weathered brick, and aged interior paint rarely blend with new product. Texas policies address this through matching language, and the appraisal panel values the loss according to what the policy actually says about restoring a reasonably uniform appearance. Where a slope, elevation, or continuous run cannot be repaired to a uniform look with a partial patch, the scope may extend to the full continuous surface — a distinction that turns on the policy wording and the physical continuity of the material, not on preference. On interiors, wind-driven-rain staining that crosses a ceiling plane or an open-concept wall run raises the same question, and the line-item estimate should reflect the natural break points of the material rather than an arbitrary square-foot cut.

Contents, Additional Living Expenses, and the Rest of the Claim

The appraisal discussion on this page centers on the structure, but a Houston hurricane or wind loss usually carries two other components that belong in the same file. Personal property — contents — is valued separately, often on an actual-cash-value basis unless the policy carries replacement-cost coverage on contents, and it requires its own room-by-room inventory rather than an extension of the roof scope. Water and humidity intrusion after a wind-created opening frequently damages flooring, cabinetry, and stored belongings in ways that are easy to overlook once the roof is dried in, so documenting contents early — before disposal or cleanup — matters as much as documenting the structure.

Additional living expenses, or loss of use, is the third component. When a covered loss makes a home uninhabitable, the policy typically pays the reasonable increase in living costs while repairs are completed. On larger Houston files where repairs stretch across months, this figure is not incidental, and keeping receipts for temporary housing and related costs from the day of displacement forward preserves it. Whether ALE falls within the amount-of-loss determination or is settled directly under the policy depends on the form, but the underlying records should be assembled the same way — contemporaneously and dated.

When You Disagree With the Initial Assessment

Among the most frequent questions policyholders raise is what to do after receiving an inspection result they believe does not match the damage they can see. Appraisal is one answer, but it is not the first step. The initial move is to understand precisely where the disagreement lies: is it the scope of damage, the unit pricing, the depreciation applied, or the classification of the peril itself? A second, independent inspection can clarify that, and in many files the difference narrows once both sides are working from the same field documentation — dated photography, moisture readings, and storm-date meteorological data placing wind or hail at the address.

Appraisal becomes the appropriate mechanism only once the parties have genuinely reached an impasse on the amount of loss and the disagreement is about valuation rather than coverage. A common pattern across recent Texas hail and wind files is that disputes rooted in differing damage assessments resolve when a third-party inspection corroborates the observed condition and the estimate is rebuilt line by line against that evidence. If the remaining gap is a coverage question — whether a peril is covered at all — that stays with the carrier and, if necessary, the courts, and no appraisal award can convert it. Knowing which of the two you are facing determines the right next step.

Deadlines, Supplements, and Reopening a Houston Claim

The process description above explains when appraisal is invoked but not the clock running behind it. Two separate timeframes matter on a Harris County file. The first is the contractual limitation period for filing suit, which most Texas homeowner and commercial forms shorten from the general statute — often to as little as two years and a day from the date of loss. Invoking appraisal does not by itself extend that period, so on an older Beryl- or derecho-era claim, the calendar should be checked before a demand is sent rather than after an award is signed. The second is the recoverable-depreciation window: on a replacement-cost policy, the holdback becomes payable only when repairs are completed and documented, and many forms set a deadline — commonly 180 days to a year after the ACV payment — for submitting that proof. An appraisal award that establishes the depreciation figure is of limited use if the completion documentation arrives after that window closes.

Supplemental claims deserve particular attention in Houston because Gulf humidity so often reveals damage weeks after the initial inspection. Saturated decking that reads dry at first pass, microbial growth behind drywall, and delayed flooring failure frequently surface only after the structure has fully dried. Where new damage tied to the original loss event emerges, it is generally handled as a supplement to the existing claim rather than a new one, and dated documentation of when and how the condition appeared is what connects it back to the covered peril. Assembling that record contemporaneously — drying logs, follow-up moisture readings, dated photographs of the newly exposed condition — keeps a legitimate supplement from being read as unrelated later deterioration.

Appraisal Alongside the Other Texas Dispute Paths

Appraisal is one mechanism among several available to a Houston policyholder, and it is not always the first or only one. The Texas Department of Insurance operates a voluntary mediation program for certain residential property disputes, which brings the parties together with a neutral mediator to reach a settlement — a process that addresses coverage and amount together, unlike appraisal, which is confined to the amount of loss. Mediation is non-binding until an agreement is signed; appraisal produces a binding award on valuation once any two panel members sign. The two are not mutually exclusive, and understanding which question is actually in dispute — coverage, valuation, or both — determines which path fits.

Where the disagreement is purely about the amount of loss, appraisal is usually faster and narrower than either mediation or litigation, and its award does not foreclose a separate coverage determination that remains with the carrier and, if necessary, the courts. On files where a coverage question and a valuation question sit side by side, some parties resolve the amount through appraisal first, which can remove the largest variable and clarify what genuinely remains in dispute.

Across recent Houston-metro property files involving mixed, non-hail damage, the recurring pattern was that disputes narrowed sharply once the amount of loss was fixed by documented evidence — dated field photography, a peril-specific narrative, and a line-item Xactimate scope built against the observed condition. When the valuation is settled on that footing, the parties can see plainly whether a true coverage disagreement remains or whether the dispute was, in the end, about the number. Knowing that before choosing between appraisal, mediation, and litigation saves both time and expense.

Frequently Asked Questions

How much does a Houston insurance appraisal cost?

Houston property appraisals typically cost $750–$5,000 depending on property size and claim complexity. Hurricane and large commercial claims may run higher due to the extensive damage documentation required. This is still a fraction of the cost of insurance litigation through an attorney.

Do you appraise hurricane damage in Houston?

Yes. Houston hurricane claims are among our most common engagements. We appraise wind damage, rain intrusion through compromised roofing, fallen tree damage, flying debris impact, and the consequential interior damage caused by roof breaches during named storm events. We carefully document the wind vs. water distinction that's critical for coverage determination.

Can you serve as umpire for Houston insurance disputes?

Yes. Marshall Smith, CPAU, provides neutral umpire services for disputed Houston claims. As a certified umpire, Marshall delivers binding impartial evaluations that resolve the dispute without litigation. This process typically concludes in 90–120 days — far faster and less expensive than a lawsuit.

What's the difference between flood damage and storm damage in Houston?

Flood damage (rising water) requires a separate NFIP or private flood policy and isn't covered under standard homeowner's insurance. Storm damage — including wind-driven rain through a compromised roof, hail damage, and wind damage — is covered under standard policies. The distinction matters enormously for Houston claims, and we carefully document which damage results from which peril.

How soon can you inspect my Houston property?

We typically schedule Houston property inspections within 5–10 business days of engagement. After major storm events, demand increases significantly — we recommend reaching out as soon as possible after receiving a claim determination you disagree with.
