Peril

A specific cause of loss, such as fire, wind, theft or water, that a policy covers or excludes; it is the cause of the damage rather than the damage itself.

Also called: peril insured against, cause of loss

A peril is a cause of loss: fire, windstorm, hail, theft, lightning, a burst pipe, a falling tree. It is the event that does the damage, not the damage itself. Smoke-stained walls and a charred roof are the loss; the fire is the peril. The distinction matters because homeowners policies are organized around perils. The policy either lists the perils it covers or lists the ones it excludes.

Those two approaches are named perils and open perils. On the standard ISO HO-3, the dwelling and other structures are covered for all risks of direct physical loss unless excluded, while personal property is covered only for the named perils the form lists. If you file a claim under a named-perils coverage, the cause must match one of them.

Many disputes come down to identifying the right peril. Wind-driven rain damage, a leak that built over months and a sewer backup might each look like "water damage," yet the policy treats them differently. When two perils combine, language such as an anti-concurrent causation clause can decide the outcome.

Ask your adjuster to state in writing which peril they believe caused the loss. For the exclusions behind these disputes, read our guide to named perils vs open perils coverage.

Named perils Coverage that applies only to the causes of loss listed in the policy, so a claim is paid only if the damage came from one of them. Open perils Coverage that applies to any direct physical loss unless the policy specifically excludes the cause, so the insurer must point to an exclusion to deny a claim. Exclusion A policy provision that removes coverage for a stated cause, type of loss, property or circumstance that the coverage would otherwise reach. Concurrent causation The question of how to decide coverage when a covered cause and an excluded cause combine to produce one loss, such as wind and storm surge in a hurricane. Efficient proximate cause A legal test that decides coverage by asking which cause set the others in motion and dominated the loss when covered and excluded causes combine.
