Rank 1 is the highest. Overall, hail and wind losses count buildings; the tornado row counts everything FEMA exposes, so it overstates building damage. Expected annual loss is an average over many years for the whole county, not a forecast for one roof.

What stands out in Sangamon County

  • FEMA expects hail in Sangamon County to cost $50 per $1 million of buildings a year: 2.25 times the U.S. median and 1.09 times the IL county median, ranked 963rd of 3,126 counties nationally and 46th of 102 in Illinois.
  • FEMA expects strong wind in Sangamon County to cost $13 per $1 million of buildings a year: 0.66 times the U.S. median and 0.24 times the IL county median, ranked 1,971st of 3,121 counties nationally and 92nd of 102 in Illinois.
  • FEMA expects tornado in Sangamon County to cost $311 per $1 million of buildings a year: 1.56 times the U.S. median and 1.22 times the IL county median, ranked 996th of 3,144 counties nationally and 23rd of 102 in Illinois.
  • Applying FEMA's estimate to a $170,300 home, the average yearly loss in Sangamon County is about $8.55 for hail and $2.27 for wind before any deductible; at the U.S. median county rates it would be $3.81 and $3.47.
  • If the next years look like 2014 to 2025, a roof kept 20 years in Sangamon County meets about 56.7 hail days of 1 inch or more; the median county in NOAA's file (1,275 counties) would give 35.0.
  • Built in 1973, the median home in Sangamon County is 53 years old, so an original roof has outlived a 3-tab shingle (15 to 20 years) and an architectural one (25 to 30 years); 85.1% of its 93,151 homes are at least 26 years old.
  • March to June holds 111 of the 143 hail reports in Sangamon County (78 percent); the quietest month is October, with 0 reports.

What hail and wind cost a home here in an average year

Enter a home value. The calculator applies Sangamon County’s own loss rate: the county’s expected yearly loss divided by the value of its buildings. It starts at the Census median home value for the county.

$8.55hail, a year; $3.81 at the U.S. median county rate
$2.27strong wind, a year; $3.47 at the U.S. median county rate
$217hail and wind together over 20 years, at today’s rate

Formula: home value × Sangamon County yearly loss ÷ building value. Hail: $3,203,566 ÷ $63,773,851,996 = 0.0000502. Wind: $851,937 ÷ $63,773,851,996 = 0.0000134. This is FEMA’s estimate of average damage to buildings and does not account for your deductible. Tornado is left out because FEMA’s tornado loss counts people and other exposure, not only buildings.

Read this as a yardstick. The rate is an average over every building in the county, from sheds to office towers, and over many years. Real losses come in rare, large storms; a roof with no damage in 19 years can need full replacement in the 20th. The figure is not a quote and not a prediction for one address.

How old the roofs are

Census counts homes by the decade they were built. Under each bar is the number of hail days of 1 inch or more that an original roof from that decade has met, at Sangamon County’s 2014 to 2025 pace of 2.83 such days a year. Most roofs have been replaced since; the row shows what a roof that never was would have taken.

Questions

How high is storm risk in Sangamon County?

FEMA's National Risk Index gives Sangamon County an overall score of 91.70 (Relatively Moderate), 262nd of 3,144. Hail scores 95.64 (Relatively High), strong wind 86.42 (Relatively High) and tornado 97.14 (Relatively High).

In Sangamon County, how many hail reports has NOAA logged?

A report is one entry for one storm in one county, so counts follow where people live as well as where hail fell. NOAA has 143 for Sangamon County between 2014 and June 2026, on 36 days with hail of 1 inch or more; the largest stone was 3.25 inches.

What do hail and wind cost a home in Sangamon County each year, on average?

Applying FEMA's county rates to its median home value of $170,300: FEMA's estimate is about $8.55 a year for hail and $2.27 for wind, before any deductible, against $3.81 and $3.47 at the U.S. median county rates. This is an average over many years and all buildings, not a prediction for one roof; one bad storm costs far more than the average year.

How does Sangamon County compare with the rest of Illinois?

Per $1 million of buildings Sangamon County loses $50 to hail a year, against $46 in the median county of the state. Among 102 rated counties it is 6th for hail, 23rd for strong wind and 8th for tornado.

How old are the roofs in Sangamon County?

The median home was built in 1973, 53 years ago, and 85.1% of the 93,151 housing units in Sangamon County date from before 2000. Asphalt shingles are rated 15 to 20 years (3-tab) or 25 to 30 years (architectural), so an original roof of either kind is past its rated life. The Census does not record when a roof was replaced.

What does expected annual loss mean?

It is FEMA's estimate of the average yearly loss from a hazard, in dollars, summed over the county. It is built for comparing counties at planning level, not for pricing one house.

Does a high rating mean my roof will be damaged?

No. The index compares counties and cannot say what will happen on your street. After a storm, a roof inspection is the only way to know.
