If your roof is 15 years old or older, your home insurance policy may already be treating it differently than you think. You're probably still paying the same premium. But when you file a claim after the next hail storm, the check your carrier sends might cover a fraction of what a new roof actually costs.
This is the ACV problem, and it's hitting Illinois homeowners harder every year.
What RCV and ACV actually mean
Every homeowners policy covers your dwelling at one of two methods: replacement cost value or actual cash value.
Replacement cost value (RCV) pays what it costs to replace or repair the damaged component at today's prices. If a hail storm destroys your roof and a new one costs $18,000, your carrier pays $18,000 minus your deductible.
Actual cash value (ACV) deducts depreciation first. That same $18,000 roof, if it's 15 years old, might have 45 percent of its useful life subtracted before the check is written. Your payout would be around $9,900. You cover the rest.
On paper, those both look like "coverage." In practice, one leaves you with $7,000 to $10,000 out of pocket on a single claim.
How carriers decide which method applies to your roof
Until recently, most standard Illinois homeowners policies covered all structural components, including the roof, at replacement cost. That's been changing.
Carriers across Illinois have been quietly adding ACV schedules for roofing to new policies and renewals. The threshold is usually roof age. If your roof is under 10 years old, most carriers still offer RCV. Between 10 and 15 years, it depends on the carrier and the product tier. At 15 years and older, a significant portion of the Illinois market now defaults to ACV for roof claims.
Some policies are structured as "limited roof payment" or "functional replacement cost" for older roofing, which is a variation of ACV with slightly different math but the same basic outcome: the carrier pays based on the roof's remaining utility, not what it costs to replace it.
The change often happens at renewal without any explanation beyond a policy endorsement that's easy to overlook. One year you have replacement cost on your roof. The next year you have a depreciation schedule. The premium might be slightly lower, or unchanged. But your actual protection is meaningfully reduced.
Illinois hail and why this matters here specifically
Illinois ranked second in the country for hail damage losses in 2024. The Chicago suburbs, DuPage County included, sit in a corridor that sees significant hail events almost every spring and summer.
For Naperville, Wheaton, Aurora, and the surrounding areas, hail isn't a hypothetical risk. It's a seasonal reality. The state records between 200 and 300 hail events per year. In a notable storm year, a single event can generate tens of thousands of claims across the western suburbs in an afternoon.
Roofing contractors in DuPage County and Will County stay genuinely busy in part because of how frequently severe weather damages roofs here. The average roof replacement in the Chicago area runs $14,000 to $26,000 depending on size, pitch, and materials. On a 2,000 square foot home with a steep pitch and architectural shingles, you're likely looking at the upper half of that range.
If your carrier pays you ACV on a 20-year roof and applies 50 percent depreciation, a $22,000 replacement job becomes an $11,000 payout before your deductible. Add a 2 percent wind/hail deductible on a $400,000 home, and you're contributing $8,000 just from the deductible. The actual out-of-pocket number can easily reach $19,000 to $20,000 on what should have been a fully covered claim.
Reading your declarations page
Most homeowners don't know which method their policy uses for the roof until after a claim.
Pull out your declarations page. Look for language like:
- "Replacement cost on dwelling" covers the whole house at RCV, including the roof, unless the policy endorsements say otherwise
- "Extended replacement cost" or "guaranteed replacement cost" is stronger than standard RCV
- "Roof surfacing, ACV" or "limited roof payment" means ACV applies specifically to the roof even if the rest of the dwelling is RCV
- "Functional replacement cost" is similar to ACV with a different calculation method
If you see the third or fourth item, you're on an ACV schedule for your roof. If you see the first and you're not sure, look at the endorsements section. Carriers often add roof ACV as a separate endorsement that doesn't change the main declarations page.
Confused? Call your agent and ask directly: "Is my roof covered at replacement cost or actual cash value?" Get the answer in writing, or pull the specific endorsement language from your policy.
How ACV depreciation is calculated
Depreciation isn't arbitrary. Carriers use a formula based on the expected useful life of the roofing material and the current age of the roof.
Asphalt shingles, which cover the majority of Illinois suburban homes, typically have a rated lifespan of 20 to 25 years. A carrier using a 25-year life on a 20-year-old roof would apply 80 percent depreciation, meaning they'd pay 20 percent of the replacement cost. On an $18,000 roof, that's $3,600.
In practice, most carriers apply somewhat less aggressive depreciation than that, but the math still produces uncomfortable results for homeowners with older roofs. A 15-year-old roof commonly sees 40 to 60 percent depreciation applied under an ACV schedule.
Some policies offer "recoverable depreciation," where the carrier withholds the depreciation amount initially but releases it once you complete the repair. That's meaningfully better than non-recoverable ACV. But you still have to front the cash to finish the job before you see the full payment.
What carriers are looking for at renewal
Underwriting standards in Illinois have tightened considerably. Several large carriers are now:
- Running aerial imagery on homes before renewal to assess roof condition
- Requiring documented roof age and material during the application process
- Adding ACV schedules automatically for any roof over a stated age threshold
- Non-renewing policies on homes with roof conditions they consider substandard
- Requiring proof of roof replacement before issuing replacement cost coverage on the new policy
If your home comes up in an aerial review with visible granule loss, curling shingles, or other age indicators, you may receive a conditional renewal requiring a roof inspection or documentation of repairs. Some homeowners have found this out by receiving a letter mid-year rather than at renewal.
This isn't uniformly applied across the market. Independent agents who work with multiple carriers see meaningful variation in how aggressively different underwriters scrutinize older roofs in 2026. Some carriers are still more forgiving on moderately aged roofs in good condition. But the trend has been toward stricter application of ACV schedules, not looser.
Your options if you have a 15-year-plus roof
You've got several realistic paths, and they're not mutually exclusive.
Get a roof inspection. Before anything else, know what you're actually dealing with. A reputable local roofing contractor can assess the remaining life on your current roof and tell you whether it's genuinely at end of life or just showing cosmetic aging. An inspection typically costs $100 to $200. If the roof has another 5 to 8 years left and is in structurally sound condition, that's a very different situation from a roof that's already failing.
Shop the market with an independent agent. ACV schedules aren't universal. Carriers vary significantly in where they draw the age threshold and how aggressively they depreciate older roofs. An independent agent who can quote your home across multiple carriers may find options that still offer RCV coverage, possibly with conditions attached. Moving to a carrier that prices older roofs at RCV can be more valuable than a lower premium from a carrier that applies aggressive depreciation.
Replace the roof before the next renewal. Not always financially practical, but if your roof is genuinely aging and you've been putting it off, doing it proactively changes the insurance conversation entirely. A new roof resets the clock. You're eligible for RCV coverage again, and many carriers offer meaningful discounts for new roofs. Some offer a new-roof discount of 10 to 20 percent on the dwelling portion of your premium. On a $2,400 annual premium, that's $240 to $480 per year in savings going forward.
Understand your deductible structure. If you're on ACV with a percentage wind/hail deductible, know exactly what your out-of-pocket exposure looks like on a total loss scenario. Do the math with your actual numbers. Knowing the number in advance lets you decide whether to hold additional reserves, adjust your deductible, or make the roof replacement a higher priority.
Ask about endorsement options. Some carriers offer endorsements that restore replacement cost coverage on older roofs at an additional premium. It's not universally available, and the cost varies. But asking costs nothing. If your carrier or a competitor can get you back to RCV on a 17-year-old roof for $150 to $200 per year in additional premium, that calculation is worth running against your actual claim exposure.
The timing issue for Illinois homeowners
April through June is peak hail season in northern Illinois. But late summer and early fall aren't quiet either. Severe convective storms track through DuPage County and the collar counties well into September, and a single afternoon can produce claims across the Naperville corridor that keep adjusters busy for weeks.
Finding out your roof is on an ACV schedule during a claim is the worst time to find out. At that point your options are limited. You're dealing with whatever policy you have.
The time to understand your coverage is now, before the next storm. Pull your policy. Check the endorsements. Ask your agent directly about your roof. If you've had the same policy for three or more years without reviewing it, there's a real chance your coverage changed at some renewal and you don't know it yet.
If your roof is under 15 years old and in decent condition, this may not be an immediate issue. But if you're at or past that threshold, it's worth a deliberate look. The difference between RCV and ACV on a hail claim in DuPage County or Will County isn't a technicality. It can be $8,000 to $12,000 out of your pocket on a claim you thought was fully covered.
