Does Homeowners Insurance Cover Water Damage? What US Homeowners Should Know
Standard US homeowners insurance policies (such as the standard ISO HO-3 form) cover water damage only if the event is 'sudden and accidental' and originates from within your home's internal plumbing, 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).
