Which of these is a named peril insured against on a broad form Homeowners policy?

Explanation

Weight of ice, snow or sleet sits on the broad list alongside fire, windstorm, explosion, riot, aircraft, vehicles, smoke, vandalism, theft, falling objects, freezing and volcanic eruption. Seepage that continues over a period of time, settling and rust are all maintenance conditions the form treats as the owner's problem rather than sudden accidental losses.
