What Is a Peril in Home Insurance?
A peril is a specific cause of loss, like fire or wind. Your policy lists which perils it covers.

Your policy works by naming perils one by one, then covering the damage those specific things cause. A fire that burns the kitchen is covered because fire is a listed peril. Water that seeps up through the foundation during heavy rain usually is not, because that falls under flood, which home insurance leaves out entirely. Before closing, read the declarations page your lender received and check which perils are actually named. If something like earthquake or flood worries you given where the house sits, that's a separate policy to ask about now, not after you move in.
Two policies can list different perils for the same house, and the gap often shows up in the fine print rather than the price. Before you commit to the one your lender suggested, it's worth checking what another insurer would actually name as covered, especially for anything specific to this property. Comparing quotes now, before closing, means you find out what's excluded while you still have time to add a separate policy for it.
Named perils versus open perils, which kind is your policy?
Policies are built one of two ways. A named-peril policy lists exactly what's covered. If the cause of damage isn't on that list, it isn't paid for. An open-peril policy, sometimes called special form, works the opposite way. It covers everything except what it specifically excludes. Most standard homeowners policies written today are open-peril for the house itself, which is why the declarations page matters more than the word "comprehensive" on a brochure. Personal belongings inside the house are often covered on a named-peril basis even when the dwelling isn't, so the two halves of the same policy can work differently.
A question like "is water damage covered" doesn't have one answer, because of this split. A pipe that bursts inside a wall is sudden and accidental, and that kind of water damage is typically covered. Water that backs up through a sewer or sump pump usually isn't, unless it's added back in as an endorsement, which is an add-on that changes what a policy covers. Same word, water, two different outcomes. The only way to know which one applies to your policy is to read what's excluded, not just what's listed as covered.
Wear and tear, neglect, and gradual damage sit outside every homeowners policy regardless of which style it's built on. A roof that leaks because it's twenty years old and never maintained isn't a peril in the insurance sense. It's deterioration, and no policy pays to fix the normal aging of a house. An inspection report that flags an older roof or an aging furnace can affect what an insurer is willing to cover, or push the deductible higher for that specific item, and this matters at closing. Ask the inspector's report questions before the binder is issued, not after.
The declarations page will tell you which structure you're dealing with. If it names perils specifically, read the list and ask what's missing. If it says special form or open peril, read the exclusions section instead, since that's where the real boundaries sit. Either way, the goal before closing is the same. Know what happens if the thing you're most worried about, whether that's an old roof, a basement below grade, or a tree hanging over the house, actually fails. Confirm it in writing rather than assuming it's covered because the policy sounds broad.
What's excluded that people assume is covered?
Every homeowners policy carries a list of exclusions that sit apart from perils entirely, and they trip up first-time buyers more than anything else in the contract. Earth movement is one. That covers earthquakes, sinkholes, and land settling, and it's excluded even on an open-peril policy. Flood is another, and it's excluded by name no matter how the rest of the policy is written. These aren't gaps an insurer forgot to mention. They're standard exclusions built into the policy form itself, which is why asking about them separately before closing matters more than reading the perils list twice.
Mold and pest damage fall into a gray area worth understanding before you sign anything. Mold that results from a covered peril, say a burst pipe that wasn't caught for a few days, is often covered up to a limit stated in the policy. Mold that shows up because of long-term humidity or a leak nobody fixed is treated as a maintenance issue, not a peril, and it's excluded. Termites, rodents, and general pest damage are excluded outright in almost every policy, since insurers treat infestations as preventable through upkeep rather than as a sudden loss. If the inspection flagged any of these, ask directly how the policy treats them rather than assuming the broad wording covers it.
Ordinance or law coverage is one more piece worth knowing about before closing, especially on an older house. If the home is damaged badly enough that local building codes require the whole structure, or a major system, to be brought up to current code during repair, a standard policy often won't pay for that upgrade cost. It only pays to restore what was there. This is usually a separate add-on, and it matters more the older the house is, since code requirements have changed more since it was built.
None of this means a particular policy is weak or that the house is a bad buy. It means coverage does different work depending on which exclusion sits next to it. The declarations page and the exclusions section together tell the real story. For a house with an old roof, a basement, or a tree close to the structure, it's worth asking an insurer directly how each of these exclusions applies before the binder goes to the lender.
Before the binder goes out
Check the exclusions section against what the inspection flagged, the roof, the basement, the tree over the house. If any of those aren't clearly covered, ask about adding coverage now, while there's still time before closing.
