A
Actual Cash Value (ACV)
Actual Cash Value is the current monetary value of your roof, accounting for depreciation from age and wear. Under ACV coverage, when you file a claim, the insurance company deducts depreciation from the replacement cost. For example, if a new roof costs $15,000 but your roof is 60% depreciated, the ACV is only $6,000. Unlike RCV coverage, this depreciation is permanent — you cannot recover it even after completing repairs.
AIUA
The Alabama Insurance Underwriting Association serves as the wind pool for coastal Alabama, primarily Baldwin and Mobile counties. Like Mississippi's MWUA, it provides wind and hail coverage only — you need a separate standard policy for non-wind perils. Properties must be in the designated area and unable to find coverage in the standard market to qualify.
Assignment of Benefits (AOB)
An Assignment of Benefits transfers your right to file and manage your insurance claim to a third party, typically a roofing contractor. While this can be convenient, it means you lose control over claim negotiations, billing, and potential litigation against your carrier. Florida has enacted reforms limiting AOB abuse. Before signing, understand that you're giving up significant rights — and consider whether a public adjuster might be a better option for managing your claim.
C
Citizens Property Insurance
Citizens Property Insurance Corporation is Florida's state-created, not-for-profit insurer designed as a last resort for homeowners who cannot find coverage in the private market. Unlike wind pools in Alabama and Mississippi (which cover only wind/hail), Citizens provides full-peril coverage. To qualify, you must demonstrate that you've been unable to obtain comparable coverage from standard carriers at a rate within a specified percentage of Citizens' rate.
Cosmetic Damage Exclusion
A cosmetic damage exclusion means your policy won't cover damage that affects only the appearance of your roof, not its ability to protect your home. This is most commonly applied to hail damage — dents in metal ridge vents, gutters, or soft metals that still function properly. The critical distinction is cosmetic vs. functional: if the damage shortens the component's lifespan or impairs its performance, it may be functional damage even if it also looks bad.
D
Deductible
Your deductible is your share of the cost before insurance kicks in. Homeowners policies typically have two deductibles: a standard deductible (usually $500-$2,500) for most claims, and a separate hurricane or named-storm deductible (often a percentage of your dwelling coverage) for storm events. The deductible is subtracted from the claim payment, not added to it.
Depreciation
Depreciation represents the decrease in your roof's value over time due to aging, weathering, and normal wear. Insurance companies calculate depreciation based on the roof's age relative to its expected lifespan and its current condition. The way depreciation is handled — recoverable vs. non-recoverable — is one of the most consequential differences in roof insurance coverage.
E
Endorsement
An endorsement is an amendment to your insurance policy that modifies its terms. Endorsements can expand coverage (adding ordinance or law coverage, increasing limits) or restrict it (adding a cosmetic damage exclusion, raising deductibles). They appear on your declarations page as additional documents. Review all endorsements carefully — they can significantly change what your policy covers.
Exclusion
An exclusion is a specific peril, type of damage, or circumstance that your policy will not cover. Standard homeowners policies exclude wear and tear, maintenance failures, and gradual deterioration. Many Gulf Coast policies add specific exclusions for cosmetic damage (especially hail dents to metal components). Understanding your exclusions is as important as understanding your coverage — they define the limits of your protection.
F
FORTIFIED
FORTIFIED is a nationally recognized building standard created by the Insurance Institute for Business & Home Safety (IBHS). It specifies construction methods and materials that exceed minimum building codes for resistance to severe weather, particularly wind and hail. The three levels — Roof, Silver, and Gold — build progressively from roof system upgrades to whole-building protection. FORTIFIED designation is valid for five years and requires re-evaluation to maintain.
H
Hurricane Deductible
A hurricane deductible is triggered only when a hurricane warning is issued by the National Hurricane Center. It's usually expressed as a percentage (1%-10%) of your dwelling coverage amount, making it significantly higher than your standard deductible. On a $300,000 home with a 2% hurricane deductible, you'd pay $6,000 out of pocket before insurance covers anything — far more than a typical $1,000 or $2,500 standard deductible.
M
MWUA
The Mississippi Windstorm Underwriting Association provides wind and hail insurance for properties in the state's designated coastal zone — primarily Harrison, Hancock, and Jackson counties. MWUA covers wind and hail damage only; you need a separate standard homeowners policy for fire, theft, liability, and other perils, plus a separate flood policy if in a flood zone. This creates a multi-policy structure that homeowners in other states don't deal with.
N
Named-Storm Deductible
A named-storm deductible activates when damage results from any named tropical storm or hurricane — a broader trigger than a hurricane-only deductible. This is the common format in Alabama and some Mississippi policies. Since tropical storms are named before reaching hurricane strength, this deductible activates more easily than a hurricane-specific one.
Non-Recoverable Depreciation
Under Actual Cash Value coverage, depreciation is permanently deducted from your claim settlement. Whether or not you repair the roof, you cannot reclaim this amount. On an older roof, non-recoverable depreciation can represent a substantial portion of the replacement cost, leaving a significant gap between what insurance pays and what repairs actually cost.
Non-Renewal
Non-renewal occurs when your insurance carrier decides not to offer you a new policy when your current one expires. This is different from cancellation, which terminates coverage mid-term (usually for non-payment). Common reasons for non-renewal include roof age, roof condition, claims history, or the carrier exiting your geographic area. States require minimum advance notice: Florida (120 days), Alabama (75 days), Mississippi (60 days).
O
Ordinance or Law Coverage
Ordinance or law coverage is a policy endorsement that pays for the additional cost of bringing your roof up to current building codes when it's repaired or replaced due to a covered loss. Building codes change over time, and a roof built to 2005 code may need significant upgrades to meet 2026 standards. Without this endorsement, you pay the code-compliance difference out of pocket — which can be thousands of dollars, especially on older homes.
P
Proof of Loss
A proof of loss is a sworn, notarized statement you submit to your insurance carrier documenting the facts and dollar amount of your claim. Not all carriers require one initially, but many do — and some require it within 60 days of the loss. Missing the proof of loss deadline can jeopardize your claim. If your carrier requests one, treat it as urgent and consider having a public adjuster help prepare it.
Public Adjuster
A public adjuster is licensed by your state's Department of Insurance to represent policyholders in claim negotiations. Unlike the carrier's adjuster (who works for the insurance company), a public adjuster works exclusively for you. They inspect damage, prepare estimates, file paperwork, and negotiate with the carrier. They typically charge 10-15% of the final settlement. Most valuable for large or complex claims where the fee is offset by a higher settlement.
R
Recoverable Depreciation
When you have Replacement Cost Value coverage, the carrier's initial payment withholds the depreciated amount. This withheld depreciation is 'recoverable' — after you complete the roof repair or replacement and submit receipts showing the actual cost, the carrier reimburses the depreciation. You must complete the work within the policy's timeframe (typically 180 days to 2 years) to recover this amount.
Replacement Cost Value (RCV)
Replacement Cost Value is the full cost to replace your damaged roof with equivalent materials and workmanship at today's prices, regardless of how old your roof was. Under RCV coverage, the carrier initially withholds depreciation but reimburses it after you complete the repairs and submit receipts. This is the more favorable coverage type for homeowners.
S
Scope of Loss
The scope of loss is the carrier's formal documentation of the damage to your property — what they found, what they attribute to the covered event, and what repairs they'll pay for. When you disagree with the scope (the adjuster missed damage, misidentified the cause, or underestimated the repair needs), you dispute it by requesting a re-inspection or filing a supplement with your own documentation.
Strengthen Alabama Homes
Strengthen Alabama Homes is an Alabama state program that provides matching grants of up to $10,000 to help homeowners retrofit their roofs to meet FORTIFIED Roof standards. Funded by a portion of insurance premium taxes, the program dramatically improves the ROI of FORTIFIED upgrades for Alabama homeowners. Demand typically exceeds funding, so application timing matters. The program is available statewide, not just in coastal counties.
Supplement
A supplement is a formal request for additional funds beyond the initial claim settlement. It's typically filed when your contractor discovers damage that wasn't visible during the adjuster's inspection — like rotted decking under shingles, or additional damaged areas revealed during tear-off. Supplements are a normal part of the claims process and are not adversarial. Your contractor or public adjuster usually prepares the documentation.
W
Wind Pool
Wind pools are state-established insurers of last resort that provide wind and hail coverage when private carriers won't. In Alabama, the AIUA covers Baldwin and Mobile counties. In Mississippi, the MWUA serves designated coastal areas. In Florida, Citizens Property Insurance provides broader coverage. Wind pools typically require proof that you've been declined by standard carriers and often have higher premiums or coverage limitations.
