Peril

What a peril is, and why it matters

A peril is the cause of a loss. Insurance does not pay because a roof is damaged; it pays because a covered peril (hail, wind, fallen tree) caused the damage. The same physical damage can be fully covered, partially covered, or not covered at all depending only on the peril that caused it. This is the single most important distinction in property insurance.

Named-peril vs. open-peril policies

• Named-peril policies (HO-1, HO-2, HO-8): Only the perils listed in the policy are covered. Anything not listed is excluded. The burden is on the homeowner to show the loss was caused by a listed peril.
• Open-peril (all-risk) policies (HO-3 dwelling, HO-5 dwelling and contents): Everything is covered except what is specifically excluded. The burden shifts to the insurer to prove an exclusion applies. This is the modern standard for the dwelling on most homeowners policies.

The 16 standard named perils (HO-2 / HO-3 contents)

#	Peril	Common claim example
1	Fire and lightning	House fire; lightning strike fries electronics
2	Windstorm and hail	Tornado damage; hail-pitted roof
3	Explosion	Gas line; water-heater rupture
4	Riot and civil commotion	Vandalism during unrest
5	Aircraft	Debris from aircraft strike
6	Vehicles	Car driven into living room or fence
7	Smoke	Sudden, accidental smoke from a fire on premises
8	Vandalism and malicious mischief	Graffiti, broken windows (often excluded if vacant)
9	Theft	Burglary of contents; capped sublimits on jewelry, firearms
10	Falling objects	Tree limb through the roof
11	Weight of ice, snow, sleet	Roof collapse under snow load
12	Accidental discharge of water from plumbing	Burst pipe inside the wall
13	Sudden tearing apart of HVAC or appliance	Cracked HVAC heat exchanger
14	Freezing of plumbing	Frozen pipe burst (requires reasonable heat)
15	Sudden damage from artificially generated electrical current	Power surge fries hard-wired panel
16	Volcanic eruption	Ash, lava flow (excludes earthquake)

Perils that are never covered by standard homeowners

• Flood (rising surface water) — requires NFIP or private flood policy
• Earthquake, earth movement, sinkhole — requires earthquake endorsement or stand-alone policy
• War, nuclear hazard, government action
• Intentional acts by the insured
• Wear and tear, gradual deterioration, maintenance
• Insect, rodent, mold, fungus damage (very limited exceptions)
• Settling, cracking, foundation movement over time

The "covered peril" trap on water and roof claims

Two of the most-denied claim categories illustrate why peril matters:

• Sudden vs. gradual water: A pipe that bursts is a covered peril (accidental discharge). The same leak that drips slowly for six months is excluded as gradual leakage. The damage looks identical; the peril determines coverage.
• Wind vs. wear on roofs: Shingles lifted by a documented storm are covered (wind). Shingles failing because they are 25 years old is excluded as wear and tear — even if the failure happened during a storm. Adjusters look at hail bruise patterns, lift patterns, and granule loss to decide which peril applies.

Why open-peril (HO-3 / HO-5) matters

An open-peril dwelling form covers any sudden, accidental cause of loss to the structure unless specifically excluded. That means an unusual loss — a hawk dropping a fish through a skylight, a meteor strike, an unidentified projectile — is covered because it is not on the exclusion list. On a named-peril HO-2, the homeowner has to fit the loss to one of the 16 named causes or recover nothing.

How Agents can help

Agents read the policy form (HO-1, HO-2, HO-3, HO-5, HO-8, DP-1, DP-3) and identify whether the dwelling and the contents are on a named-peril or open-peril basis. For homeowners on HO-8 (older home actual-cash-value forms) or HO-2 contents forms, Agents identify carriers willing to upgrade to HO-3 dwelling and HO-5 contents — usually for a modest premium difference that pays for itself the first time an unusual peril shows up.
