How to Tell if a House Is Insurable
Insurers check the roof's age, the wiring and plumbing, past claims, and how close the house is to a fire hydrant.
Free to compare
Insurers decide this by running the property through underwriting before they'll quote it, and the roof is usually the first thing that trips an application. A roof past 20 years, or one with visible wear, can get a house declined outright or quoted with a separate, higher roof deductible. Knob-and-tube wiring, galvanized plumbing, or an old claims history on the property do the same. Ask the seller's agent for the roof's age and any past insurance claims now, before you're a week from closing and your lender is waiting on a binder.
Insurers don't all weigh the same things
One insurer might decline a 22-year-old roof outright. Another quotes it with a higher roof deductible. Comparing quotes before closing shows which insurers will actually cover this house, and what each one charges for the risk.
What if no insurer will cover the house at all
Some houses are harder to place than others. A roof near the end of its life, a prior water claim, or a location prone to wildfire or wind can push a house into what insurers consider high-risk territory. If several insurers turn it down, that doesn't always mean the house can't be insured. It usually means it needs a different kind of policy, often through a state-run plan built for properties the standard market won't take, sometimes called a FAIR plan. These cost more and cover less than a standard policy, but they exist so a house isn't completely uninsurable.
Before assuming the worst, find out exactly why an insurer declined the house. A roof that needs replacing might make the house insurable once it's fixed, and some sellers will negotiate a credit or do the repair before closing rather than lose the sale. A past claim that was storm damage, not a recurring issue, might not worry a different insurer the way it worried the first one. The decline letter or the agent's notes usually say what triggered it, and that detail tells you whether this is fixable before closing or something you're inheriting.
Lenders need proof of coverage to close, not proof of a specific insurer, so a FAIR plan or a non-standard carrier can satisfy that requirement if it comes to it. It's worth asking the lender directly whether they have any restrictions on the type of policy they'll accept, since most just need a binder showing the dwelling coverage matches the loan amount. This isn't the outcome most buyers expect walking in, but it keeps a deal from collapsing over something that has a workaround.
If the house keeps coming back hard to insure across multiple companies, treat that as information about the house itself, not just the insurance search. A house that's expensive to insure because of its roof, wiring, or claims history is often a house with deferred maintenance the seller hasn't fully disclosed. Getting a second opinion from an inspector, alongside the insurance quotes, can save more than the premium difference between carriers.
What the inspection has to do with any of this
A home inspection and an insurance underwriting review aren't the same thing, but they look at a lot of the same places. Roof condition, electrical panel, plumbing, foundation. If the inspector flags something, expect an insurer to flag it too, usually before the inspector's report is even finished. Scheduling the inspection early, rather than treating it as a formality near the end of the contingency period, gives time to act on what it finds before it becomes a problem with the binder.
Some repairs matter more to an insurer than they do to an inspector. A cracked walkway or a dated kitchen won't affect a quote. A 20-year-old roof, aluminum wiring, or a sump pump with no backup will. If the inspection turns up one of these, it's worth asking the seller to fix it or credit the cost before closing, rather than finding out at the insurance stage that the house needs the repair anyway to get covered at a normal rate.
Ask the inspector directly whether anything they saw tends to cause insurance problems. Most have seen a roof or panel sink a quote before and will say so if asked, even though it's not part of their standard report. That one question can save a week of back-and-forth with insurers later, especially if it surfaces something fixable while there's still room to negotiate with the seller.
None of this replaces getting the quote itself. A house can pass inspection cleanly and still come back expensive to insure, because of its location or claims history rather than its condition. Inspection and insurability overlap, but they answer different questions, and a buyer who only checks one of them can still end up surprised by the other.
Before you request quotes
Find the roof's age and any insurance claims filed on the house in the past five years. Both numbers will come up in underwriting, and knowing them now means no surprises when the binder is due.
