Expected yearly loss, in dollars
| Hazard | This county, total a year | Per $1M of buildings | State median county | U.S. median county | Rank per $1M, U.S. | Rank per $1M, state |
|---|---|---|---|---|---|---|
| Hail | $4,089,680 | $93 | $51 | $22 | 545 of 3,126 | 30 of 99 |
| Strong wind | $982,475 | $22 | $66 | $20 | 1,467 of 3,121 | 96 of 99 |
| Tornado | $5,487,691 | $125 | $417 | $199 | 1,955 of 3,144 | 98 of 99 |
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 Scott County
- FEMA expects hail in Scott County to cost $93 per $1 million of buildings a year: 4.18 times the U.S. median and 1.81 times the IA county median, ranked 545th of 3,126 counties nationally and 30th of 99 in Iowa.
- FEMA expects strong wind in Scott County to cost $22 per $1 million of buildings a year: 1.10 times the U.S. median and 0.34 times the IA county median, ranked 1,467th of 3,121 counties nationally and 96th of 99 in Iowa.
- FEMA expects tornado in Scott County to cost $125 per $1 million of buildings a year: 0.63 times the U.S. median and 0.30 times the IA county median, ranked 1,955th of 3,144 counties nationally and 98th of 99 in Iowa.
- Applying FEMA's estimate to a $212,500 home, the average yearly loss in Scott County is about $20 for hail and $4.77 for wind before any deductible; at the U.S. median county rates it would be $4.75 and $4.33.
- If the next years look like 2014 to 2025, a roof kept 20 years in Scott County meets about 38.3 hail days of 1 inch or more; the median county in NOAA's file (1,275 counties) would give 35.0.
- Built in 1972, the median home in Scott County is 54 years old, so an original roof has outlived a 3-tab shingle (15 to 20 years) and an architectural one (25 to 30 years); 80.3% of its 78,130 homes are at least 26 years old.
- March to June holds 109 of the 128 hail reports in Scott County (85 percent); the quietest month is January, with 0 reports.
What hail and wind cost a home here in an average year
Enter a home value. The calculator applies Scott 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.
Formula: home value × Scott County yearly loss ÷ building value. Hail: $4,089,680 ÷ $43,763,720,054 = 0.0000934. Wind: $982,475 ÷ $43,763,720,054 = 0.0000224. 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 Scott County’s 2014 to 2025 pace of 1.92 such days a year. Most roofs have been replaced since; the row shows what a roof that never was would have taken.
Bars: share of 78,130 housing units by decade built. Figures under the decade: hail days met by an original roof, at the county’s 2014 to 2025 pace. The pace of earlier years is unknown.

How high is storm risk in Scott County?
FEMA's National Risk Index gives Scott County an overall score of 84.89 (Relatively Moderate), 476th of 3,144. Hail scores 96.06 (Relatively High), strong wind 96.44 (Relatively High) and tornado 82.89 (Relatively Moderate).
In Scott 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 128 for Scott County between 2014 and June 2026, on 25 days with hail of 1 inch or more; the largest stone was 4 inches.
What do hail and wind cost a home in Scott County each year, on average?
Applying FEMA's county rates to its median home value of $212,500: FEMA's estimate is about $20 a year for hail and $4.77 for wind, before any deductible, against $4.75 and $4.33 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 Scott County compare with the rest of Iowa?
Per $1 million of buildings Scott County loses $93 to hail a year, against $51 in the median county of the state. Among 99 rated counties it is 5th for hail, 5th for strong wind and 13th for tornado.
How old are the roofs in Scott County?
The median home was built in 1972, 54 years ago, and 80.3% of the 78,130 housing units in Scott 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.
