Every year a roof ages, it costs its insurer more, and the cost curve is not a straight line. Combining published claims data on roof condition, claim frequency, and claim severity, an old roof (roughly 16 years or older, in poor condition) drives about 48% higher pure premium than a new one, per CAPE Analytics claims research, split into roughly 25% higher claim frequency and 19% higher claim severity. The steepest part of that curve arrives once a roof drops below four years of remaining useful life, where Verisk finds severe-weather damage runs about 50% higher. This report models how hail and wind claim frequency and severity scale with roof age, names where the payout curve bends, and shows why the homeowner and the insurer feel that curve in opposite directions.
How much more does an old roof cost insurers than a new one?
An old roof in poor condition costs an insurer roughly 48% more per exposure than a new roof in good condition, according to CAPE Analytics claims research using Nearmap aerial imagery (published 2018). That 48% pure premium gap breaks into two parts: poor and satisfactory (P&S) roofs showed 25% higher claim frequency and 19% higher claim severity than excellent and good (E&G) roofs. Against a full portfolio average, poor-condition roofs still ran 16% higher frequency, 10% higher severity, and 27% higher pure premium.
Roof condition is the observable proxy for age. Verisk’s 2026 U.S. roof report puts the average life expectancy of the most common roof cover at about 20 years, so a roof scored moderate to poor is usually one that has aged into that condition. Verisk found roofs in moderate to poor condition carry about 60% higher loss costs than roofs in good or excellent condition, based on its Roof Condition Score 2025 baseline data. Roof-related items already make up around 30% of all line items inside U.S. property claim estimates, per the same Verisk report.
The exposure is large. Verisk estimates about 75 million U.S. properties have roofs near the end of their useful life, and pegs annual premium leakage from underestimated roof age at $1.31 billion. Wind and hail damage accounted for 42% of all insured home losses from 2018 to 2022, the leading cause of homeowner claims, per Insurance Information Institute data cited in Matic’s 2025 Home Insurance Report.
At what roof age do hail claims get more severe?
Claim severity climbs gradually through a roof’s first decade, then bends sharply once the roof passes roughly 15 years and falls under four years of remaining useful life. Verisk reports that roofs with less than four years of remaining roof life sustain about 50% more damage during severe weather than roofs with eight or more years of remaining life. On a 20-year cover, that four-year-remaining threshold lands near year 16, which is where the severity curve steepens most.
Two mechanisms stack at that point. First, aged asphalt shingles lose granules, become brittle, and crack rather than flex under hail impact, so a given hailstone produces a larger repairable or replaceable area. Second, a roof already near failure is more likely to be totaled by a storm than spot-repaired, converting a partial claim into a full replacement. The result is that the same hailstorm writes a materially larger check on a 17-year-old roof than on a 6-year-old one.
The macro trend amplifies the age effect. Convective storms carrying wind and hail cost U.S. insurers $58 billion in 2024, and total roof claim costs reached nearly $31 billion that year, up about 30% from 2022, per Matic’s 2025 report. Verisk separately reported U.S. roof claim costs above $30 billion in 2024. Rising per-claim severity means the penalty for insuring an old roof grows in dollar terms even when claim counts hold flat.
The Roofing Brief roof-age claim model
The table below is a Roofing Brief calculation, not a published carrier schedule. It anchors the two endpoints to sourced figures (CAPE Analytics for the E&G-to-P&S frequency and severity gaps, Verisk for the remaining-life severity jump) and interpolates the interior age bands. Frequency and severity are indexed to a new roof at 1.00. Pure premium is frequency multiplied by severity, the insurer’s expected loss per exposure. ACV recovery is the homeowner’s actual cash value payout as a share of replacement cost, using standard straight-line depreciation of about 5% per year on a 20-year asphalt-shingle life.
| Roof age band | Typical condition | Relative claim frequency | Relative claim severity | Relative pure premium (insurer cost) | ACV payout as % of replacement cost |
|---|---|---|---|---|---|
| 0 to 5 years | Excellent / Good | 1.00 | 1.00 | 1.00 | 75% to 100% |
| 6 to 10 years | Good / Satisfactory | 1.08 | 1.06 | 1.14 | 50% to 75% |
| 11 to 15 years | Satisfactory | 1.16 | 1.10 | 1.28 | 25% to 50% |
| 16 to 20 years | Poor (under 4 yrs life left) | 1.22 | 1.19 | 1.45 | 0% to 25% |
| 21+ years | Poor / end of life | 1.25 | 1.19+ | 1.48+ | 0% (floored) |
How to read it: the 0-to-5 and 21+ rows are sourced endpoints. CAPE Analytics found P&S roofs ran 25% higher frequency (index 1.25) and 19% higher severity (index 1.19) than E&G roofs, which multiply to the 48% pure premium gap (index 1.48) that CAPE reported directly. The 6-to-10, 11-to-15, and 16-to-20 rows are Roofing Brief interpolations between those endpoints, aligned to Verisk’s finding that severity jumps near the four-year-remaining-life mark. The ACV column is a separate straight-line depreciation calculation, shown to make the point that insurer cost and homeowner recovery move in opposite directions as a roof ages.
Why the insurer and the homeowner feel the age curve in opposite directions
As a roof ages, the insurer’s expected cost rises while the homeowner’s actual payout falls, and the wedge between them is the depreciation the policy applies. On a replacement cost value (RCV) policy the carrier pays to replace the roof new, minus the deductible. On an actual cash value (ACV) policy the carrier pays replacement cost minus accumulated depreciation, so age directly reduces the check.
The standard depreciation formula is ACV = RCV minus (depreciation rate times RCV times age), applied straight-line. Asphalt shingles depreciate at roughly 3% to 5% per year against a 20-year life for three-tab and 25 to 30 years for architectural shingles, per industry depreciation tables (ClaimsPages, LegalClarity). A 10-year-old roof on a 20-year life is about 50% depreciated: a $15,000 replacement pays roughly $7,500 in actual cash value before the deductible.
Apply that to current costs. Verisk puts the 2025 average residential roof replacement at $17,631, up 33% from the 2021-to-2024 average, with repairs averaging $4,699. A 15-year-old roof at 75% depreciation on a 20-year schedule would recover only about $4,400 of that $17,631 in ACV before the deductible, even though the storm that damaged it may have driven the insurer’s severity 19% or more above a new-roof claim. That gap is why carriers increasingly move older roofs to ACV settlement or decline to renew them. Our companion analysis of insurance non-renewal by roof age traces where that line gets drawn by state and carrier.
What a hail claim actually costs by roof age
In dollar terms, roof age moves a hail claim on two axes at once: how often it happens and how large it runs. Insurance Information Institute data placed average wind and hail claim severity near $13,511 for 2018 to 2022. Applying CAPE Analytics’ 19% severity premium for poor-condition roofs, a Roofing Brief calculation puts an old-roof hail claim near $16,078 in severity versus that baseline, before factoring the higher frequency that compounds the annual loss cost.
- Frequency effect: poor-condition roofs file about 25% more claims than good-condition roofs (CAPE Analytics, 2018). More storms convert to filed claims because aged shingles fail at lower impact energy.
- Severity effect: each claim runs about 19% larger on a poor roof, and up to 50% larger in severe weather once remaining life drops below four years (Verisk, 2025 baseline).
- Depreciation effect: on an ACV policy the homeowner absorbs the aging as a shrinking payout, dropping toward 0% of replacement cost by year 20 (straight-line, 20-year life).
- Total-loss effect: a near-end-of-life roof is more likely to be replaced outright than repaired, so a partial hail claim becomes a full-roof claim.
Wind behaves similarly. Wind claim severity rose 23.5% and wind loss costs jumped 30.7% in 2024, per LexisNexis U.S. home insurance trend data, and all-peril severity rose about 9% between 2023 and 2024, the highest in seven years. Older roofs sit at the sharp end of that increase because their weakest components fail first. For the geographic side of this, our hail and storm loss database and severe weather roof damage report break claim volume down by state.
Where the pricing and underwriting curve is bending in 2026
Carriers are repricing roof age faster than at any recent point, and the premium spread by age is widening sharply. Matic’s 2025 report found the premium difference between roofs under five years old and roofs 11 to 15 years old grew from $49 in 2022 to $155 in 2025, a 216% increase in the age-based differential. Coverage terms shift with it: a roof that carries 100% replacement cost coverage when new may drop to about 60% once it reaches 10 years old.
Exposure is not evenly distributed. Verisk’s 2025 data shows roof age skews old in some regions and young in others: in the Northeast 18% of roofs are 31 years or older against only 14% aged 0 to 4, while in the South 28% are 0 to 4 years old and just 4% are 31-plus. In hail-designated states, 57% of homes have roofs nine years or newer versus 38% in non-hail states, a sign that repeated hail is already forcing faster roof turnover in the highest-risk markets.
One data-quality problem sits under all of it: roof age is often wrong in the file. A Claims Journal report cited by CAPE Analytics found more than two-thirds of homeowner-supplied roof ages were understated by more than five years. That understatement is exactly why aerial-imagery condition scoring has replaced self-reported age, and why a roof’s measured condition, not the number a homeowner writes on an application, increasingly sets the price. Homeowners weighing a proactive replacement can compare the impact-resistant shingle insurance discounts that offset part of the cost, and our guide to getting insurance to pay for a roof replacement covers the claim path.
Methodology and limitations
This report synthesizes published figures from CAPE Analytics (claims study using Nearmap imagery, 2018), Verisk (2026 U.S. roof report and Roof Condition Score 2025 baseline), the Insurance Information Institute, Matic (2025 Home Insurance Report), LexisNexis (2025 U.S. home insurance trends), and standard actuarial ACV depreciation tables. Frequency, severity, and pure premium indexes in the model table are anchored to CAPE Analytics’ reported E&G-versus-P&S gaps at the endpoints; interior age bands are Roofing Brief interpolations, not directly observed values.
Several limits apply. Roof age is a proxy for condition, not a perfect substitute: a well-maintained 18-year-old roof can outperform a neglected 10-year-old one, and condition scoring captures that better than age alone. CAPE Analytics figures reflect a sampled U.S. portfolio and specific data years; individual carrier books differ. Depreciation schedules vary by material, region, and carrier, and many insurers apply proprietary Xactimate tables that depart from the straight-line rates used here. Dollar illustrations use national averages; local labor, material, and storm exposure move the actual numbers materially. Figures apply to U.S. residential asphalt-shingle roofs unless otherwise noted, and coverage outcomes depend on policy form (RCV versus ACV), deductible structure, and state regulation.
Frequently asked questions
How much more does an old roof cost insurers than a new one? An old roof in poor condition drives roughly 48% higher pure premium than a new roof in good condition, per CAPE Analytics claims research: about 25% higher claim frequency and 19% higher claim severity combined. Verisk separately found moderate-to-poor-condition roofs carry about 60% higher loss costs than roofs in good or excellent condition.
At what roof age do hail claims get more severe? Severity rises gradually through the first decade, then bends sharply after roughly 15 years, once a roof drops below four years of remaining useful life. Verisk reports those roofs sustain about 50% more severe-weather damage than roofs with eight or more years of life left, because aged shingles crack instead of flexing under hail impact.
Does roof age reduce how much insurance pays for hail damage? On an actual cash value (ACV) policy, yes. The payout equals replacement cost minus depreciation, and asphalt shingles depreciate about 3% to 5% per year. A 10-year-old roof on a 20-year life is roughly 50% depreciated, so a $15,000 replacement pays about $7,500 before the deductible. Replacement cost value (RCV) policies avoid that reduction.
Do older roofs file more hail claims? Yes. CAPE Analytics found poor and satisfactory roofs file about 25% more claims than excellent and good roofs, and about 16% more than the portfolio average. Aged shingles fail at lower hail impact energy, so more storms convert into filed claims on an old roof than on a new one.
What roof age do insurers treat as high risk? Many carriers begin tightening terms around 10 years and treat roofs past 15 to 20 years as high risk, often shifting them to ACV settlement or declining renewal. The average asphalt-shingle roof cover lasts about 20 years (Verisk), and coverage that starts at 100% replacement cost when new can drop toward 60% by year 10.
Why is roof age pricing changing so fast in 2026? Roof claim costs reached nearly $31 billion in 2024, up about 30% from 2022, and replacement costs rose 33% to a $17,631 average (Verisk). The premium gap between roofs under 5 years and roofs 11 to 15 years widened from $49 in 2022 to $155 in 2025, a 216% increase, as carriers price the widening loss-cost curve.
