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 York County

  • FEMA expects hail in York County to cost $7.71 per $1 million of buildings a year: 0.34 times the U.S. median and 0.75 times the SC county median, ranked 2,235th of 3,126 counties nationally and 36th of 46 in South Carolina.
  • FEMA expects strong wind in York County to cost $1.46 per $1 million of buildings a year: 0.07 times the U.S. median and 0.14 times the SC county median, ranked 2,965th of 3,121 counties nationally and 42nd of 46 in South Carolina.
  • FEMA expects tornado in York County to cost $347 per $1 million of buildings a year: 1.74 times the U.S. median and 1.84 times the SC county median, ranked 861st of 3,144 counties nationally and 7th of 46 in South Carolina.
  • Applying FEMA's estimate to a $322,700 home, the average yearly loss in York County is about $2.49 for hail and $0.47 for wind before any deductible; at the U.S. median county rates it would be $7.21 and $6.57.
  • If the next years look like 2014 to 2025, a roof kept 20 years in York County meets about 31.7 hail days of 1 inch or more; the median county in NOAA's file (1,275 counties) would give 35.0.
  • Built in 1999, the median home in York County is 27 years old, so an original roof has outlived a 3-tab shingle (15 to 20 years) and is inside the rated life of an architectural one (25 to 30 years); 51.6% of its 118,063 homes are at least 26 years old.
  • March to June holds 41 of the 47 hail reports in York County (87 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 York 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.

$2.49hail, a year; $7.21 at the U.S. median county rate
$0.47strong wind, a year; $6.57 at the U.S. median county rate
$59hail and wind together over 20 years, at today’s rate

Formula: home value × York County yearly loss ÷ building value. Hail: $519,604 ÷ $67,406,309,385 = 0.0000077. Wind: $98,418 ÷ $67,406,309,385 = 0.0000015. 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 York County’s 2014 to 2025 pace of 1.58 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 York County?

FEMA's National Risk Index gives York County an overall score of 88.68 (Relatively Moderate), 357th of 3,144. Hail scores 61.70 (Relatively Low), strong wind 95.36 (Relatively High) and tornado 96.91 (Relatively High).

In York 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 47 for York County between 2014 and June 2026, on 19 days with hail of 1 inch or more; the largest stone was 2.75 inches.

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

Applying FEMA's county rates to its median home value of $322,700: FEMA's estimate is about $2.49 a year for hail and $0.47 for wind, before any deductible, against $7.21 and $6.57 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 York County compare with the rest of South Carolina?

Per $1 million of buildings York County loses $7.71 to hail a year, against $10 in the median county of the state. Among 46 rated counties it is 20th for hail, 1st for strong wind and 2nd for tornado.

How old are the roofs in York County?

The median home was built in 1999, 27 years ago, and 51.6% of the 118,063 housing units in York County date from before 2000. Asphalt shingles are rated 15 to 20 years (3-tab) or 25 to 30 years (architectural), so an original 3-tab roof is past its rated life and an architectural one is inside it. 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.
