Peril

A specific cause of loss — such as fire, windstorm, or theft — that triggers an insurance claim when it damages covered property.

Definition

In insurance terminology, a peril is the direct cause of a loss event, as distinguished from a hazard (a condition that increases the likelihood of a peril occurring). Common property perils include fire, lightning, windstorm, hail, explosion, riot, aircraft impact, vehicle impact, smoke, vandalism, theft, and water damage from plumbing failures. Perils can be covered, excluded, or conditionally covered based on policy form, endorsements, and state-specific filings. Courts and claims adjusters distinguish between the proximate cause of a loss (the dominant peril) and concurring causes (contributing factors), which can affect whether an exclusion bars the claim. After Hurricane Katrina, insurers and policyholders famously disputed whether damage was caused by wind (a covered peril) or flood (an excluded peril), a debate that generated years of litigation. Understanding which perils are covered — and which are not — is the foundational literacy skill of property insurance.
