Do I Need to Tell My Insurance Company About Renovations?
Yes. Major renovations can change your rebuilding cost, so your insurer needs to know to keep coverage accurate.

If you were dropped or non-renewed, an unreported renovation can be part of why. Insurers reassess risk when they find out the house changed, sometimes after a claim shows wiring, plumbing, or a roof was replaced without being logged. A rewired house or a new roof can work in your favor, since both often lower risk. But if the insurer finds out only after damage happens, they may question why the dwelling coverage didn't match the real house. Your declarations page shows what they have on file now, which is worth checking before you apply anywhere else.
A Renovation Can Cut Both Ways
A new roof or rewired house can lower what you pay once it's on file. Left unreported, the same upgrade can leave your dwelling coverage wrong and work against you at renewal.
What Counts as a Renovation You Need to Report
Not every change to the house needs a phone call. A new coat of paint or new carpet doesn't change what it would cost to rebuild, so it doesn't change your coverage. What matters is anything that affects the structure, the systems, or the value of the house. A new roof, rewired electrical, updated plumbing, an added room, a finished basement, a new HVAC system all count. If a contractor pulled a permit for it, your insurer probably wants to know about it.
Scale matters more than the project name. A small bathroom refresh is different from a kitchen remodel that added square footage or moved walls. The real question is always whether the work changed what it would cost to rebuild the house from the ground up, since that's what your dwelling coverage is supposed to match. New cabinets and appliances can raise that number. New paint doesn't.
Timing matters too. Report the renovation when it's done, not months later when something goes wrong. Insurers adjust your dwelling coverage and sometimes your premium based on what you tell them, and that adjustment only helps you if it happens before a claim, not after. If a fire or a pipe burst happens and the insurer discovers the house had significant unreported work done, they may argue your coverage never matched the real house. That can slow down or reduce a payout.
If you're not sure whether something counts, the safest move is to mention it anyway. A quick call or a note through the insurer's online portal costs nothing. Most changes that raise questions are ones that touch wiring, plumbing, roofing, or square footage. If you're currently shopping for a new policy after a non-renewal or cancellation, this is also the moment to get those details right from the start. A new application is a clean slate, and listing accurate, current details about the roof, the wiring, and any additions can work in your favor instead of becoming a problem later.
What If the Renovation Happened Before the Non-Renewal?
If the insurer who dropped you never knew about a finished basement or a rewired panel, that gap doesn't follow you to a new policy automatically, but it also doesn't disappear. A new insurer will ask about the age of the roof, the wiring, the square footage, and the condition of major systems as part of underwriting. This is the point where old, unreported work needs to surface. Leaving it off again just repeats the same problem with a different company.
Some homeowners worry that mentioning a renovation will raise the price they're quoted. Sometimes it does, since more square footage or a bigger kitchen can mean a higher cost to rebuild. An accurate quote is worth more than a cheaper one that's wrong. A low premium built on outdated information about the house isn't a lower cost. It's a coverage gap that hasn't been found yet.
Permits and contractor records help here. If the renovation was done properly, there's likely a permit on file with the local building department, and the contractor may have paperwork showing what was replaced and when. Having that on hand when you apply makes underwriting faster and gives the insurer a reason to price the house on what it actually is now, not on guesswork. A rewired house with documentation behind it reads differently to an underwriter than the same house with no paper trail.
Non-renewals tied to an old roof or outdated wiring deserve a direct answer. If that roof or that wiring has since been replaced, say so on the application rather than holding it back. Insurers who pulled back from older homes or certain risk profiles are often willing to reconsider once the actual condition of the house has changed. The renovation that might have gone unreported before is, in this situation, the strongest argument for better terms now.
One Thing Worth Doing Now
Pull your declarations page and check what it lists for the roof's age, wiring, and square footage. If a finished renovation isn't reflected there, that's the detail to raise before you compare new quotes.
