Does Homeowners Insurance Cover Water Damage? What US Homeowners Should Know
Under standard American property insurance contracts—predominantly written on the ISO HO-3 form—water damage is covered strictly if the event is 'sudden and accidental' and stems from a domestic pipe burst inside the structure, heating, or appliance systems—such as a ruptured copper pipe or an exploded water heater. Insurance does NOT cover gradual leaks, ongoing seepage, deferred maintenance, sewer or drain backups (unless you purchased an optional rider), or exterior overland flooding (which requires a separate FEMA National Flood Insurance Program policy).
