What drives the risk for expensive homes in Iowa
- Catastrophe exposureIowa's main exposures are severe convective storms (hail, straight-line wind and derechos), tornadoes, river flooding and winter storms. The August 10, 2020 derecho alone produced more than 200,000 insurance claims and over $1.6 billion paid within three months. Source
- Wind and hurricane deductiblesIowa lets homeowners policies carry a separate deductible for wind or storm losses, which may be a percentage of the dwelling limit; for example, 2% on a $250,000 dwelling is a $5,000 deductible. I found no Iowa rule setting a maximum or trigger. Source
- FloodFlood is excluded from homeowners policies and NFIP caps building coverage at $250,000. Expensive homes near the Des Moines, Raccoon, Iowa and Cedar rivers or on the Iowa Great Lakes may need private or excess flood coverage. Source

When the standard market says no, and what earns credits
- Insurer of last resort and wind poolsThe Iowa FAIR Plan Association is the insurer of last resort for property owners who can't get coverage in the voluntary market. Its policies give basic coverage, narrower than standard market policies. Source
Worth knowing in Iowa
Because hail and wind are so common, many Iowa policies now carry roof endorsements that pay actual cash value (depreciated) instead of replacement cost, or apply a depreciation schedule based on roof age and material. Owners of expensive homes with slate, tile or high-end shingle roofs should check for these endorsements. Source
