Insurance & Xactimate Glossary

338 terms used in insurance restoration, explained for practitioners.


A

Activity Code

A code within Xactimate that identifies what type of work is being performed - remove, replace, repair, clean, etc. Combined with the item code to create the full line item.

ACV (Actual Cash Value)

Actual Cash Value (ACV) is the current real-world value of damaged property, calculated by subtracting depreciation from the Replacement Cost Value (RCV). ACV determines the first check the homeowner receives on an insurance claim.

Additional Insured

A person or entity added to a contractor's insurance policy to extend coverage. Property owners and general contractors often require this before allowing work to begin.

Additional Living Expenses (ALE)

Additional Living Expenses (ALE) is the insurance coverage that pays the difference between a policyholder's normal living costs and the inflated costs of living elsewhere while their home is uninhabitable during covered repairs.

Additional Living Expenses Claim

A formal request to the insurance carrier for reimbursement of costs incurred while displaced from the home during covered repairs. Requires documentation of expenses and proof they exceed normal living costs.

Adjuster

An adjuster is a licensed professional who inspects property damage and writes or reviews estimates for an insurance claim. Adjusters are classified into three types: staff adjusters (carrier employees), independent adjusters (contracted during catastrophe events), and public adjusters (representing the policyholder).

Adjuster Licensing

The state-issued credential required for individuals to work as insurance adjusters, with requirements varying by state and adjuster type. Most states require written examinations, continuing education, and periodic renewal.

Aggregate Limit

The maximum total amount an insurance policy will pay for all claims during a policy period, typically one year.

AHJ (Authority Having Jurisdiction)

The government entity responsible for enforcing building codes and issuing permits in a specific area. Typically the city or county building department.

Air Mover

A high-velocity fan used in water damage restoration to promote evaporation from wet materials. Typically placed at a 45-degree angle against wet surfaces.

Air Sampling

The collection and analysis of airborne particles to detect mold spores, asbestos, or other contaminants. Used in mold assessment and clearance testing.

Air Scrubber

A portable HEPA-filtered air cleaning device used during restoration and remediation to remove airborne contaminants including mold spores, dust, and particulate matter from the work environment. Can also be configured for negative air operation.

All-Perils Policy

A homeowner's insurance policy that covers all causes of loss except those specifically listed as exclusions. Also called an open-perils or special form policy. Broader coverage than a named-peril policy.

All-Risk Policy

An insurance policy that covers all causes of loss except those specifically excluded. Also called open peril or special form. Broader coverage than named peril policies.

Aluminum Coil Stock

Aluminum coil stock is flat-rolled aluminum sheet material used by roofers and siding installers to fabricate custom flashing, trim, and accessories on site by cutting and bending to the required profile.

Anti-Concurrent Causation

A policy clause that excludes coverage when a covered peril (like wind) and an excluded peril (like flood) combine to cause damage. If both causes contribute, the entire loss is denied under this clause.

Antimicrobial Treatment

The application of chemical agents to building materials during water damage restoration to prevent mold growth. Applied after cleaning and before drying is complete.

Appraisal Clause

An appraisal clause is a provision in most property insurance policies that allows either the policyholder or the carrier to invoke a formal, binding appraisal process when they disagree on the value of a covered loss.

Appraisal Demand

A formal request to invoke the appraisal clause in an insurance policy when the policyholder and carrier disagree on the value of a loss. Each side selects an appraiser, and a neutral umpire breaks ties.

Appraisal Process

The formal dispute resolution procedure outlined in most property insurance policies where each party appoints an appraiser and, if they cannot agree, a neutral umpire decides the claim value. Binding in most states.

Appraiser

An insurance appraiser is a professional appointed by either the policyholder or the carrier during the appraisal process to independently assess the value of a disputed insurance claim by comparing damage estimates and repair costs line by line.

Apron Flashing

A continuous piece of sheet metal installed at the base of a vertical surface where it meets the roof plane, such as at the front of a chimney or dormer. Directs water flowing down the vertical surface onto the shingles.

Arbitration

A binding or non-binding dispute resolution process where a neutral arbitrator hears both sides and makes a decision on the claim amount. Faster and less expensive than litigation.

Architectural Shingles

A premium asphalt shingle with a dimensional, layered appearance that mimics wood shake or slate. Heavier and more durable than 3-tab shingles with a longer warranty.

Asphalt Shingles

The most common residential roofing material in the United States, made from fiberglass mat coated with asphalt and mineral granules. Available in 3-tab and architectural styles.

Assignment of Benefits (AOB)

Assignment of Benefits (AOB) is a legal agreement in which the policyholder transfers their insurance claim rights to a third party - typically the contractor or restoration company - allowing that party to file claims, negotiate, and collect payment directly from the carrier.

B

Back Charge

A deduction from a contractor's or subcontractor's payment for work that was deficient, incomplete, or caused damage that another party had to correct. Common in multi-trade restoration projects where one trade's error affects another.

Bad Faith Claim

A bad faith claim is a legal action filed against an insurance carrier for unreasonably denying, delaying, or underpaying a valid insurance claim in violation of its contractual duty to act honestly toward the policyholder.

Betterment

Betterment is a charge applied by the insurance carrier when repairs result in an upgrade over the property's pre-loss condition, such as code-required materials that did not exist on the original structure. Betterment is frequently disputed when the upgrade is mandated by current building code.

Betterment Charge

The amount deducted from an insurance claim payment when the repair or replacement results in a condition that is better than the pre-loss condition. The policyholder pays the difference between restoring to pre-loss condition and the actual upgrade.

Blistering Shingles

Raised bubbles or pockets on the surface of asphalt shingles caused by trapped moisture or volatile gases in the shingle mat expanding under heat. Blisters can be mistaken for hail damage.

Board-Up

The process of securing a structure by covering broken windows, doors, or openings with plywood to prevent unauthorized entry and weather damage.

Carrier

A carrier is the insurance company that underwrites the homeowner's policy, collects premiums, evaluates claims, and issues payments. In the restoration industry, 'carrier' is the standard term for the insurer - whether State Farm, Allstate, USAA, Travelers, or any other property insurance company.

Carrier Response Time

The amount of time an insurance carrier takes to respond to a claim filing, supplement request, or estimate submission. Response time requirements vary by state.

Catastrophe Adjuster

An independent adjuster deployed to disaster areas after major weather events to handle the surge in insurance claims. CAT adjusters work on contract for insurance carriers during catastrophic events.

Catastrophe Team (CAT Team)

A catastrophe team is a group of adjusters, typically independent adjusters, deployed by an insurance carrier to a disaster-affected area to process a high volume of claims resulting from a single weather event.

Categories (Xactimate)

Categories in Xactimate are the organizational structure that groups line items by trade or work area - including roofing (RFG), exteriors (EXT), plumbing (PLM), electrical (ELC), painting (PNT), and interior (INT). Category assignment directly affects O&P calculations and XactAnalysis review outcomes.

Category 3 Water

Water that is grossly contaminated and can cause severe illness or death if ingested. Includes sewage backups, flooding from rivers or streams, and any standing water that has been stagnant long enough to support microbial growth.

Category Selector

The category selector in Xactimate is the interface used to find and add specific line items by navigating through trade categories, subcategories, and individual selector codes.

Cause of Loss

The specific event or peril that caused the damage in an insurance claim. Determining the cause of loss is critical because coverage depends on whether that peril is covered under the policy.

Certificate of Completion

A document signed by the contractor and property owner confirming that all work specified in the contract has been completed satisfactorily.

Certificate of Insurance (COI)

A document issued by an insurance company proving that a contractor or business has active insurance coverage. Required by most property owners and general contractors before work begins.

Claims Examiner

An insurance company employee who reviews and evaluates property damage claims from the office. Claims examiners approve or deny claims, authorize payments, and oversee the work of field adjusters.

Claims Process

The claims process is the end-to-end sequence from damage event to final payment, consisting of: first notice of loss (FNOL), adjuster inspection, scope of loss, initial ACV payment, repair work, supplement filing, depreciation release, and final settlement. The average residential claim takes 30-90 days to settle.

Clearance Testing

Post-remediation testing to verify that mold levels have returned to acceptable levels. Typically involves air sampling and visual inspection by an independent assessor.

Code Compliance

The requirement that all construction work meets current local, state, and national building codes. Insurance claims may include code upgrade costs when repairs must bring the structure up to current code.

Code Upgrade

A code upgrade is repair work required to bring damaged property up to current building codes (IRC, IBC, or local amendments), even if the pre-loss condition did not meet those codes. Code upgrades are covered under most insurance policies but are frequently disputed by carriers as betterment.

Code Upgrade Supplement

A supplement filed to cover the cost of bringing damaged areas up to current building code requirements that exceed what was originally installed. Code upgrades are covered under ordinance or law provisions.

Coinsurance

A provision requiring the policyholder to insure the property to a certain percentage of its value (typically 80%). Failure to meet the requirement results in reduced claim payments.

Collateral Damage

Collateral damage in insurance claims refers to additional damage caused to undamaged components during the process of repairing or replacing the primary damaged items.

Comparative Negligence

A legal principle that reduces a claim payment based on the policyholder's share of fault for the damage. If the homeowner's deferred maintenance contributed to the loss, the payout may be reduced.

Cricket (Roof)

A peaked structure built behind a chimney or other roof obstruction to divert water around it. Prevents water and debris buildup that can cause leaks.

D

Deductible

A deductible is the fixed dollar amount or percentage the policyholder pays out of pocket before insurance coverage applies. The deductible is subtracted from the first ACV payment, not from the depreciation release.

Dehumidifier

Equipment used in structural drying to remove moisture from the air. Commercial dehumidifiers process significantly more water per day than residential units.

Denied Claim

A denied claim is an insurance claim that the carrier has rejected entirely, refusing to issue any payment. A denial is not the final outcome - it is the starting point for appeals, supplements with stronger documentation, public adjuster involvement, or the appraisal process.

Deodorization

The process of eliminating odors from a structure after fire, smoke, water, or biological contamination using techniques including thermal fogging, hydroxyl generation, ozone treatment, and chemical counteractants.

Depreciation

Depreciation is the reduction in value of property due to age, wear, and condition. In insurance claims, depreciation is calculated per line item in Xactimate based on each component's specific age and expected useful life - not as a flat percentage across the entire claim.

Depreciation Holdback

The portion of the replacement cost that an insurance carrier withholds from the initial claim payment, representing the depreciation on damaged materials and labor. This amount is recoverable after repairs are completed.

Depreciation Schedule

A depreciation schedule is the table or formula an insurance carrier uses to calculate how much value each component of a property has lost due to age and wear, directly reducing the actual cash value payment on a claim.

Desiccant Dehumidification

Line items are the individual entries in an Xactimate estimate, each representing a specific task, material, or service with its own unit price, quantity, and trade category classification.

Litigation

Filing a lawsuit against an insurance company over a claim dispute. Typically a last resort after negotiation, appraisal, and mediation have failed.

Loss Date

The specific date when the insured property was damaged by the covered peril. Determines which policy terms apply, starts statute of limitations clocks, and establishes the timeline for reporting and filing requirements.

Loss of Use

Loss of use (Coverage D) is the insurance coverage that pays for a policyholder's additional living expenses when their home is uninhabitable during covered repairs. Loss of use is a separate coverage from the property repair estimate, with its own limit typically set at 20-30% of dwelling coverage.

The regional database of material and labor costs that Xactimate uses to calculate estimate totals. Updated regularly by Verisk to reflect current market conditions in each geographic area.

Production Orders

Production orders are documents generated from an Xactimate estimate that list the specific materials, quantities, and labor tasks needed to complete a job. Production orders translate the insurance estimate into actionable work instructions for crews and suppliers.

Progress Billing

A payment structure where the contractor invoices the property owner or insurance carrier at predetermined milestones during the project rather than requesting full payment at completion. Common on large restoration and reconstruction projects.

Progress Payment

A partial payment made to a contractor as work is completed, rather than paying the full amount at the end. Common in larger restoration projects.

Project Manager (Restoration)

The person responsible for coordinating all aspects of a restoration project, from initial assessment through final completion, including managing subcontractors, scheduling, and communication with the carrier.

Proof of Loss

A proof of loss is a sworn, notarized statement the policyholder submits to the insurance carrier documenting the exact dollar amount of damage claimed. Missing the submission deadline - typically 60-90 days from the carrier's request, under most state regulations - can void the claim entirely.

Proof of Loss Form

A sworn, notarized document required by the insurance carrier in which the policyholder formally states the facts of the loss, the amount claimed, and the cause of damage. Failure to submit a timely proof of loss can result in claim denial.

Property Damage

Physical damage to tangible property caused by a covered peril. In liability insurance, refers to damage a contractor causes to someone else's property.

Proximate Cause

The primary or dominant cause of a loss. When multiple events contribute to damage, insurers look at the proximate cause to determine whether the loss is covered.

Psychrometry

The science of measuring and analyzing the thermodynamic properties of air-water vapor mixtures. In restoration, psychrometric readings (temperature, humidity, dew point, grains per pound) guide drying strategy and equipment placement.

Public Adjuster

A public adjuster (PA) is a licensed professional who represents the policyholder exclusively in an insurance claim, working on contingency of 5-15% of the final settlement. A Florida study (OPPAGA/FAPIA) found that settlements average 19% higher with public adjuster involvement, even after the PA's fee.

Punch List

A list of remaining items that need to be completed or corrected before a construction project is considered finished. Created during the final walkthrough.

R

Rake Edge

The inclined edge of a roof that runs from the eave to the ridge along a gable end. The rake is finished with drip edge, fascia, or trim to protect the exposed edge of the roof deck.

RCV (Replacement Cost Value)

Replacement Cost Value (RCV) is the cost to repair or replace damaged property with materials of like kind and quality at current prices, with no deduction for depreciation. RCV is the ceiling of the claim from which all other numbers - ACV, depreciation, and deductible - are calculated.

Re-Inspection

A re-inspection is a follow-up property inspection requested by either the carrier or the contractor after the initial scope of loss is challenged through a supplement. The carrier sends a re-inspector to verify the additional damage claims before approving payment.

Re-Inspection

A re-inspection is a follow-up property inspection requested by either the contractor, the homeowner, or the carrier to reassess damage, verify findings, or evaluate items disputed in the original scope.

Re-Roof

The process of installing a new roof, either by overlaying new shingles on existing ones or by tearing off the old roof first. Most codes limit overlays to two layers.

Recoverable Depreciation

Recoverable depreciation is the portion of the insurance claim that the carrier withholds until repairs are completed and documented. On a replacement cost policy, recoverable depreciation is released after the homeowner submits invoices and photos of completed work within the policy's recovery deadline.

Reglet

A narrow groove or channel cut into masonry or concrete to receive the top edge of counter flashing or apron flashing. Creates a mechanical lock that secures the flashing without relying solely on sealant.

Reopened Claim

An insurance claim that was previously closed but is opened again because additional damage was discovered, a supplement was submitted, or the original payment was disputed.

Reservation of Rights

A letter from an insurance company stating they will investigate and potentially pay a claim while reserving the right to deny coverage later based on their findings.

Reservation of Rights Letter

A formal letter from the insurance carrier notifying the policyholder that the carrier is investigating the claim but reserving the right to deny coverage based on specific policy provisions. Not a denial, but a warning.

Retainage

A percentage of the contract amount (typically 5-10%) withheld by the property owner until the project is fully complete. Protects against incomplete work.

Ridge Cap

Specially shaped shingles installed along the peak (ridge) of a roof where two slopes meet. Provides waterproofing and a finished appearance at the highest point.

Ridge Vent

A ventilation product installed along the peak of a roof that allows hot air to escape from the attic. Works with soffit vents to create passive airflow.

Roof Cement

Roof cement is a thick, asphalt-based sealant used to bond roofing materials, seal flashing, and make temporary or permanent repairs at joints, seams, and penetrations.

Roof Deck

The structural sheathing (typically plywood or OSB) attached to the roof trusses or rafters that forms the base surface for the entire roofing system. All underlayment, flashing, and shingles are installed on top of the roof deck.

Roof Decking

The structural base layer of a roof, typically plywood or OSB, attached to the rafters or trusses. Everything else - underlayment, shingles - sits on top of the decking.

Roof Penetration

Any object or structure that passes through the roof surface, including plumbing vents, HVAC curbs, exhaust fans, skylights, and satellite dish mounts. Each penetration requires proper flashing.

Roof Pitch

The steepness of a roof expressed as a ratio of vertical rise to horizontal run, written as X/12. A 6/12 pitch means the roof rises 6 inches for every 12 inches of horizontal distance.

Roof Square

A unit of measurement equal to 100 square feet of roof area. Roofing materials, labor, and insurance estimates are priced per square. A 2,000 square foot roof equals 20 squares.

Roof Truss

A pre-engineered structural framework made of lumber and metal connector plates that supports the roof deck and transfers the roof load to the exterior walls. Trusses are manufactured off-site and installed as complete units.

Roof Ventilation

The system of intake (soffit) and exhaust (ridge, turbine, or power vents) that moves air through the attic. Proper ventilation prevents moisture damage and extends roof life.

Roofing Consultant

An independent roofing professional who provides expert opinions, inspections, and recommendations. Roofing consultants may work for building owners, contractors, or insurance carriers.

Roofing Sealant

Roofing sealant is a flexible, weather-resistant compound applied to seams, joints, fasteners, and transitions to prevent water penetration, available in caulk, spray, and tape-applied formats.

Roofing Square

A unit of measurement equal to 100 square feet of roof area. Roofing materials, labor, and pricing are typically quoted per square.

S

S500 Standard

The IICRC standard for professional water damage restoration. Defines water damage categories (1-3), classes (1-4), and the procedures for drying and restoring structures.

S520 Standard

The IICRC standard for professional mold remediation. Defines procedures for assessment, containment, removal, and clearance of mold-contaminated structures.

Salvage

Damaged property that the insurance company takes ownership of after paying a total loss claim. The insurer may sell salvage to recover part of the claim payment.

Satellite Measurement

A roof measurement method that uses high-resolution aerial or satellite imagery combined with software algorithms to calculate roof area, slope, penetrations, and edge lengths without requiring physical access to the roof.

Scope (of Work)

The scope of work is the specific set of repairs to be performed on a project as defined by the estimate. The scope of work overlaps with the scope of loss but serves a different purpose: the scope of loss is the adjuster's damage assessment, while the scope of work is what the contractor actually builds from.

Scope Agreement

A written document signed by the contractor, homeowner, and sometimes the insurance carrier that confirms the agreed-upon scope of work, materials, and pricing before restoration work begins. Prevents disputes about what was included in the project.

Scope Creep

The gradual expansion of work beyond the original agreement without corresponding adjustments to price or timeline. Common in insurance restoration when hidden damage is discovered.

Scope of Damage

The documented extent and type of damage to a property, including affected areas, materials, and quantities. The scope of damage forms the basis of the insurance estimate.

Scope of Loss

A scope of loss is the adjuster's written, line-by-line inventory of all damage at a property and the estimated cost to repair it. Created in Xactimate, the scope of loss determines the initial claim payment and serves as the baseline for any supplements.

Scope Sheet

A scope sheet is the document or form used during a property inspection to record all observed damage, measurements, materials, and conditions before writing the formal Xactimate estimate.

Scupper

An opening in a parapet wall or roof edge that allows water to drain from a flat roof surface into a downspout or directly away from the building.

Selector Code

The alphanumeric code that identifies a specific line item in Xactimate. Each code corresponds to a particular material, labor task, or combination.

Siding Damage

Siding damage is damage to exterior siding materials (vinyl, fiber cement, LP SmartSide, wood, or aluminum) caused by wind, hail, impact, or moisture intrusion. Siding damage is among the most commonly missed items on residential insurance claims because adjusters typically focus on the roof.

Sketch

Sketch is Xactimate's built-in diagramming tool for creating floor plans, roof layouts, and property measurements. Sketch data drives all quantity calculations for line items in the estimate - a 2-square error in a roof sketch can swing the estimate by $600-$1,200.

Sketch (Xactimate)

The Sketch tool in Xactimate is the built-in diagramming feature used to draw the roof, floor plan, or exterior of a property to generate accurate measurements for the estimate.

Skylight

A window installed in the roof surface to provide natural light. A common source of leaks when flashing deteriorates or installation is improper.

Slope (Roof)

The angle of a roof surface, often used interchangeably with pitch. Steeper slopes shed water faster but are more difficult and expensive to work on.

Smoke Damage

Damage caused by smoke particles depositing on surfaces, including discoloration, odor, and corrosion. Can affect areas far from the actual fire.

Snow Guard

A device installed on a roof surface to prevent large sheets of snow and ice from sliding off the roof in an uncontrolled manner. Snow guards are most common on metal and slate roofs.

Soffit

The material covering the underside of the roof overhang (eave). Often vented to allow airflow into the attic for proper ventilation.

Soffit Vent

Perforated or slotted openings installed in the soffit panels beneath the roof overhang that allow fresh outside air to enter the attic space as part of the roof ventilation system.

Soft Metal Damage

Soft metal damage refers to dents, dings, and deformations caused by hail or debris impact on ductile metal components like aluminum gutters, vents, and flashing that deform without cracking.

Soot

Fine black particles produced by incomplete combustion of organic materials. Acidic and corrosive, soot must be cleaned quickly to prevent permanent damage to surfaces.

Staff Adjuster

A staff adjuster is a claims adjuster employed full-time by the insurance carrier who handles day-to-day claims in a defined geographic territory. Staff adjusters know local building codes and pricing, and their scopes tend to be more thorough than independent adjusters' work.

Staff Adjuster (Detailed Guide)

A staff adjuster is a full-time employee of an insurance carrier who handles claims year-round in an assigned territory, bringing deep knowledge of carrier-specific guidelines and local market conditions.

Standing Seam Metal Roof

A metal roofing system with raised interlocking seams that run vertically from the ridge to the eave, providing superior weather resistance and a lifespan of 40 to 70 years.

Starter Strip

A row of shingles or specialized starter material installed along the eaves and rakes before the first course of shingles. Provides adhesive bonding and water protection.

Starter Strip Shingle

A pre-cut or trimmed shingle strip installed along the eaves and rakes before the first course of shingles. Provides a continuous adhesive seal line and covers the gaps between the first course tab cutouts.

Statute of Limitations

The legal deadline for filing a lawsuit or taking legal action on an insurance claim. Varies by state and by type of claim. Missing this deadline forfeits the right to sue.

Steep-Slope Roof

A roof with a slope of 3:12 or greater. Most residential roofs are steep-slope and use shingles, tiles, or metal panels as the primary waterproofing layer.

Step Flashing

L-shaped pieces of metal installed where a roof meets a vertical wall, such as a chimney or dormer. Each piece overlaps the one below to channel water down the roof.

Storm Chasing

The practice of roofing contractors traveling to areas hit by severe weather to solicit homeowners for insurance restoration work. A controversial industry practice that ranges from legitimate storm response to predatory door-knocking.

Storm Damage

Storm damage is a general category covering any property damage caused by severe weather - wind, hail, rain, tornado, or a combination. Storm damage claims typically involve multiple damage types on a single property and multiple trades, making them the strongest case for overhead and profit.

Structural Drying

The controlled process of removing moisture from building materials using dehumidifiers, air movers, and monitoring equipment until materials reach their dry standard.

Subcontractor

A contractor hired by the general contractor to perform a specific trade or portion of the work, such as plumbing, electrical, or HVAC.

Subrogation

Subrogation is the legal process by which an insurance carrier pays the policyholder's claim and then pursues recovery from the third party responsible for causing the damage - such as a neighbor's insurer after their tree falls on the policyholder's roof.

Subrogation Waiver

A contractual provision in which one party waives the right to pursue subrogation claims against another party. Common in construction contracts to prevent the property owner's insurer from suing the contractor after paying a claim.

Supplement

A supplement is a formal request to increase the payout on an existing insurance claim when the original scope of loss misses damage, underestimates quantities, or excludes code-required work. Supplements average a 34.4% increase in RCV on residential claims (The Supplement Experts).

Supplement Approval

Confirmation from an insurance carrier that additional line items or amounts submitted in a supplement request have been accepted and will be paid.

Supplement Denial

A carrier's rejection of some or all line items in a supplement request. Denials must include a reason and can be appealed with additional documentation.

Supplement Request

A formal submission to an insurance carrier requesting additional payment for damage or repairs not included in the original estimate. Supplements are supported by photos, measurements, and documentation.

Surety Bond

A three-party agreement guaranteeing that a contractor will fulfill their obligations. If the contractor fails, the surety company compensates the property owner.

Synthetic Felt Underlayment

Synthetic felt is a lightweight, water-resistant roofing underlayment made from woven or spun polypropylene, serving as a secondary moisture barrier between the roof deck and the shingles.

Synthetic Underlayment

A woven or non-woven polypropylene roof underlayment that is lighter, stronger, and more slip-resistant than traditional felt paper. Increasingly required by shingle manufacturers.

T

Tear-Off

Tear-off is the complete removal of existing roofing materials down to the bare wood deck before installing new materials. Tear-off includes removal labor and disposal costs (dump fees, dumpster rental), and is one of the highest-cost line items on any re-roof estimate.

Temporary Repairs

Emergency work done to prevent further damage before permanent repairs begin. Includes tarping, board-up, water extraction, and emergency power. Typically covered separately from permanent repairs.

Test Square

A test square is a measured area on a roof, typically 10 feet by 10 feet (100 square feet), used by adjusters and inspectors to count and document hail hits, wind damage, or other storm impacts per unit area.

Thermal Imaging

The use of infrared cameras to detect temperature differences in building materials, which can indicate hidden moisture. A non-invasive method for identifying water damage behind walls and ceilings.

Thermal Moisture Survey

An inspection technique using infrared (thermal) cameras to detect temperature differences in building surfaces that indicate hidden moisture, insulation gaps, air leaks, or structural anomalies invisible to the naked eye.

Thermal Shock

Damage to roofing materials caused by rapid, extreme temperature changes that cause sudden expansion or contraction. Most common on flat roofs with dark membranes exposed to direct sunlight followed by sudden rain or nighttime cooling.

Third-Party Administrator (TPA)

A third-party administrator is an outside company hired by an insurance carrier to manage specific functions of the claims process, including contractor networks, estimate review, and payment processing.

Three-Trade Rule

The three-trade rule is the industry standard stating that when three or more distinct trades are required on a single insurance claim, the 20% overhead and profit markup (10% overhead + 10% profit) should be included in the Xactimate estimate. The three-trade rule is supported by Xactimate's own documentation and most state insurance departments.

Total Loss Determination

A total loss determination occurs when an insurance carrier concludes that the cost to repair the damaged property equals or exceeds its insured value, resulting in a payout of the policy limits rather than repair costs.

TPO Roofing

Thermoplastic Polyolefin (TPO) is a single-ply membrane roofing material used primarily on low-slope and flat commercial and residential roofs, known for its heat-welded seams and energy-efficient white reflective surface.

Trade Category Prefix

The three-letter code at the beginning of each Xactimate category that identifies the trade. RFG for roofing, PLM for plumbing, ELT for electrical, PNT for painting, etc.

Trade Groups

Trade groups are the classification system in Xactimate that organizes work by the type of trade performing it (roofing, siding, plumbing, electrical, painting, etc.). The number of trade groups assigned to an estimate directly determines O&P eligibility via the three-trade rule.

Turbine Vent

A wind-powered rotary exhaust vent installed on the roof that uses wind energy to spin internal vanes, actively pulling hot air and moisture from the attic. Also called a whirlybird vent.

U

Umbrella Policy

A supplemental liability insurance policy that provides additional coverage above the limits of the underlying homeowner's, auto, or business liability policies. Does not cover property damage to the policyholder's own home.

Umpire

An umpire is a neutral third party appointed during the insurance appraisal process when the policyholder's appraiser and the carrier's appraiser cannot agree on the value of a loss. The umpire's decision, combined with agreement from either appraiser, becomes a binding award.

Umpire (Insurance Appraisal)

A neutral third party selected by the two opposing appraisers during the insurance appraisal process to break a deadlock on claim valuation. The umpire's agreement with either appraiser creates a binding award.

Underlayment

A protective layer installed between the roof deck and shingles that provides a secondary barrier against water infiltration. Available in felt and synthetic options.

Underpayment

Underpayment is when the insurance carrier pays a claim but the amount is insufficient to cover the actual cost of repairs. Underpayment is the default outcome on residential property claims - with the average initial scope written at 50-65% of actual repair costs, 35-50% of claim value requires recovery through supplements.

Unit Price

The cost per unit of measurement for a line item in Xactimate. Units vary by item type - square feet, linear feet, each, etc.

Unit Price

The cost per unit of measurement for a specific line item in Xactimate, broken into labor and material components, and derived from the regional price list.

W

Waiver of Subrogation

An endorsement that prevents an insurance company from seeking reimbursement from a third party after paying a claim. Often required in construction contracts.

Waste Factor

Waste factor is the percentage of additional material ordered beyond exact measurements to account for cuts, breakage, defects, and roof geometry. The industry standard waste factor for simple gable roofs is 10-15%, but complex hip-and-valley roofs require 18-22% waste.

Water Damage

Water damage is property damage caused by water intrusion, plumbing failures, appliance leaks, or flooding. Water damage claims are fundamentally different from weather damage claims because they require emergency mitigation (extraction, structural drying per IICRC S500 standards) before permanent repairs can begin.

Water Extraction

The process of removing standing water from a structure using pumps, wet vacuums, and extractors. The first step in water damage restoration after the source has been stopped.

Water Mitigation Category (WTR)

The Xactimate category containing line items for water damage response - extraction, drying equipment, monitoring, antimicrobial treatment, and related services.

Wear Pattern

The visible signs of gradual material deterioration on a roof surface from aging, UV exposure, and weather cycling. Wear patterns include uniform granule erosion, curling edges, and color fading that distinguish normal aging from sudden storm damage.

Weathering vs. Damage

Weathering is the gradual deterioration of roofing materials from normal environmental exposure over time, while damage is a sudden loss of function caused by a specific event like a storm.

Wind Damage

Wind damage is property damage caused by high winds to roofing, siding, fences, and other exterior components. Wind damage claims require documentation of both the wind event itself (NOAA storm reports, weather data) and physical evidence of wind-related failure patterns such as creased shingles, missing tabs, and lifted flashing.

Wind Speed Rating

The wind speed rating is the maximum wind speed a roofing product is tested and certified to withstand when installed according to manufacturer specifications, measured in miles per hour.

Wind Uplift

The upward suction force created when wind flows over a roof surface, which can lift, curl, or tear shingles from the deck. Wind uplift is strongest at roof edges, corners, and ridge lines.

Wind/Hail Deductible

A separate deductible that applies specifically to wind or hail damage claims. Often higher than the standard deductible, sometimes expressed as a percentage of the home's insured value.

Workers Compensation

Insurance that covers medical expenses and lost wages for employees injured on the job. Required by law in most states for contractors with employees.
