The Midwest's rising storm losses and rates

Midwest homeowners are paying more because thunderstorms, not hurricanes or wildfires, have become the region's expensive peril. Hail, tornadoes and straight-line wind damage hundreds of thousands of roofs a year, and insurers answer with higher rates, percentage wind/hail deductibles, roof payment schedules and tighter renewal rules. Average premiums in most Midwest states are still near or below the national average, so the pain shows up more in deductibles and roof terms than in the headline price.

What the numbers say

Premiums look moderate. The NAIC's July 2026 homeowners report put the national average HO-3 premium at $1,737 for 2023. Across the Midwest it ranged widely.

Sources: NAIC homeowners market report (2023 data) and NAIC 2025 market share data. Nebraska's $2,142 is the seventh highest of any state; Oklahoma, at $2,486, is fifth. Wisconsin has the lowest average in the country at $923. An NAIC market dynamics report put the 2024 average direct premium per policy for the Midwest zone at $1,476, against $1,600 nationally.

The losses tell a different story. The industry's 2025 direct loss ratio on homeowners multiple peril was 55.14% nationally (NAIC). For the State Farm group, which is the largest writer in every Midwest state in this table, the 2025 direct loss ratios were:

A loss ratio above 100% means the group paid more in claims than it collected in premiums that year. One company in one year is not a state average. It does show why a state like Missouri saw the pressure it did. Missouri's Department of Commerce and Insurance counted 253,241 catastrophe claims and more than $2.9 billion paid by June 2026; the May 16, 2025 St. Louis tornado alone produced more than 10,000 claims and more than $475 million in payments. DCI's 2023 report found loss frequency rose from 4.8% in 2022 to 9.2% in 2023, with 125,231 losses averaging $16,635.

Kansas shows the same slope. The Kansas Department of Insurance reported that insurers paid $879 million on severe storm claims in 2025, about double the $442 million paid for 2023, with Sedgwick County (Wichita) accounting for $383 million after an early-September hailstorm with stones up to 2.75 inches (Insurance Journal, March 2026).

Why storms cost more every year

Aon reported in January 2026 that severe convective storms are now the costliest insured peril of the 21st century, with $52.3 billion of U.S. insured losses in 2025. Its list of the costliest events includes the August 2020 Midwest derecho at $9.2 billion. Moody's, writing in May 2026, said such losses had grown about 10% a year over the last decade, driven by more housing exposure, higher repair costs and vulnerable roofs. See severe convective storms and rising premiums for the full argument.

The mechanics matter for a homeowner:

• Hail wears roofs down. IBHS research shows asphalt shingles accumulate damage from repeated hail. Nebraska's Department of Insurance explains that lightweight composition shingles can be damaged by 1-inch hail, and heavier shingles by about 1 1/4 inches.
• Repairs cost more. Roofing labor and materials have climbed; see building materials, labor shortages and claim costs.
• Insurers count claims differently. Nebraska's department warns that some insurers count wind and hail occurrences when deciding whether to renew, even if they paid nothing.

How it reaches your policy

Rates. AM Best put the average approved homeowners increase at 13.5% in 2024, roughly 8% in 2025 and 4.3% in the first half of 2026. S&P figures cited in an Insurance Journal report of September 2026 show Minnesota at about 17.8% in 2025 and 1.6% so far in 2026. The speed of that slowdown varies by state.

Percentage deductibles. An insurer can move you from a flat $1,000 to 1%, 2% or more of Coverage A. Say your dwelling limit is $300,000 and the wind/hail deductible rises from $1,000 to 2%. A $7,000 roof repair that once paid $6,000 now pays $1,000. Minnesota regulates how: a 2024 law (Minn. Stat. 65A.29, subd. 8a) requires 60 days' notice with a worked example and a flat-dollar alternative. Most Midwest states have no such rule, so read your renewal packet. See wind and hail deductibles explained.

Roof terms. Many policies pay hail damage to an older roof at actual cash value or on a payment schedule by age. Check this before you buy a house with a 15-year-old roof. Roof payment schedules and ACV roof endorsements explains the difference.

Nonrenewal. Oklahoma's 2023 nonrenewal rate was 1.45%, up 103% since 2018, according to a December 2024 Senate Budget Committee staff report. Minnesota's 2024 law lets an insurer nonrenew a home with three or more covered lightning, wind, rain or hail losses of more than $10,000 each in five years. Missouri's DCI issued a moratorium bulletin after the 2025 storms and rescinded it effective June 1, 2026, though it still asks insurers to give extra time to owners making good-faith repairs.

What states are doing

• Minnesota requires a premium discount for a home with a FORTIFIED designation that includes the hail supplement (Minn. Stat. 65A.298), but the Strengthen Minnesota Homes grant program was unfunded as of February 2026. An industry member of the Legislature's task force wrote that Minnesota's homeowners combined ratio had been well over 100% in recent years; the task force itself pointed to "legal system abuse" as a driver.
• Oklahoma opened Strengthen Oklahoma Homes on January 12, 2026 with grants of up to $10,000 for FORTIFIED Roof with the Hail Supplement; the next statewide application period opens October 12, 2026. HB 3781 (May 12, 2026) creates a file-and-use rate process effective July 1, 2027.
• Kansas voided assignments of post-loss benefits under residential property policies (SB 55, April 3, 2026).
• Missouri offered a Homestead Disaster Tax Credit of up to $5,000 of a 2025 storm deductible, with no new credits after October 15, 2026.
• Iowa and Illinois have no statewide mitigation grant programs.

A renewal checklist for storm country

1. Compare last year's and this year's declarations pages for the wind/hail deductible, roof endorsements and any cosmetic damage exclusion.
2. Write the deductible in dollars and confirm you could pay it.
3. Confirm the roof age and material on file are right.
4. Get at least one quote from an insurer with a different roof settlement, since two policies with the same premium can pay very differently after hail.
5. Ask whether replacing the roof with an impact-resistant (Class 4) or FORTIFIED product earns a discount; see Impact-resistant (Class 4) roofs and hail discounts.
6. Learn the claim steps before the storm: hail damage claims: roofs, siding and windows and, for tornadoes, tornado damage and homeowners insurance. Be wary of door-knocking roofers who offer to waive your deductible.
7. Add water backup and flood if your basement matters, since wind and hail coverage does not include either.

Key takeaways

• Midwest premiums are still moderate in many states, but storm losses have driven insurers to raise deductibles and tighten roof terms.
• The State Farm group's 2025 direct loss ratios (NAIC) ran from 47.25% in Minnesota to 140.04% in Missouri, illustrating how unevenly the losses landed.
• Read your wind/hail deductible and roof settlement terms at every renewal; a lower premium can hide a worse policy.
• Several states now fund or require roof mitigation, so a stronger roof is the main lever you control.
