What Evidence Supports a Home Insurance Claim?
Photos and video of the damage, receipts for repairs or lost items, and a written inventory of what was damaged or stolen.

Building your case before the adjuster does
The photos and video matter most if you take them before anything gets moved or thrown out, so start there even if the adjuster is already on the way. Walk every room, not just the damaged one, since some policies cover items affected by smoke or water even if they weren't directly hit. Keep receipts for anything you buy to prevent further damage, like a tarp or a dehumidifier, because most policies cover that cost separately. For stolen or destroyed items, a bank statement, old photo, or credit card record showing you owned something carries weight when you don't have the original receipt. Write down dates and names from every call or visit, since the claim file the insurer keeps rarely matches your memory of what was said.
A documented claim gets paid faster
Insurers that know your policy is being compared tend to move. If this claim is underpaid or stalled, checking what your coverage should pay against other policies shows where the gap is.
What if the damage keeps getting worse after the loss?
Keep documenting it. A roof leak from a storm can turn into a mold problem three weeks later, and a pipe burst can leave flooring warped long after the water is gone. Take new photos as the damage develops and date them. If the claim is still open, send the new photos to the adjuster and ask that they be added to the file. If it's already closed, most insurers allow a claim to be reopened when the damage is a direct result of the original covered event, though the window to do that is set by the policy and sometimes by the state, so check the declarations page or call the insurer to ask.
The written inventory from the first days matters again here. If mold shows up in a closet that wasn't on the original list of affected rooms, the dated walkthrough notes and photos are what connect it back to the storm or the leak rather than something unrelated. Insurers are more likely to dispute damage that surfaces later if there's no record tying it to the original loss. A contractor's written assessment, separate from the insurer's own adjuster, can also help establish that the new damage came from the same cause.
Mitigation costs matter too. If a policy requires the homeowner to prevent further damage, that same requirement applies to secondary damage like mold or rot. Keep receipts for any dehumidifiers, fans, mold treatment, or temporary repairs done to stop the spread. Most policies cover these costs as part of the claim, but only if there's a record showing the steps taken and when.
Some damage never shows up as a separate claim and instead gets folded into the original one through supplemental estimates. If a contractor opens a wall during repairs and finds damage the adjuster didn't see, that's normal. Insurers expect supplemental requests in cases like this. The same documentation habits apply. Take photos before anything is covered up again, get a written estimate from the contractor, and note when the adjuster was told. A claim that grows in scope isn't unusual, but it needs the same paper trail as the first version did.
What if the adjuster's estimate leaves things out?
An adjuster's estimate is one person's reading of the damage, not a final number. It's common for an initial estimate to miss things, especially damage that isn't visible on a walkthrough, like insulation behind drywall or wiring affected by water. If the estimate looks low compared to what repairs are actually going to cost, get a second opinion from a contractor before accepting it. A written contractor estimate, itemized the same way the adjuster's was, gives something concrete to compare line by line.
Look at how the adjuster priced materials and labor, not just the total. Two estimates can list the same repairs and still land far apart because one used local contractor rates and the other used a generic pricing database. If the gap comes from pricing rather than scope, point to the contractor's rates and ask the insurer to explain the difference. If the gap comes from scope, meaning the adjuster's estimate left out a repair the contractor says is necessary, that's the stronger case to push on, since it means something was missed rather than priced differently.
Every policy allows for a claim to be reopened or supplemented when new information comes in, and asking for a re-inspection is a normal part of that process, not a confrontation. Put the request in writing, attach the contractor's estimate and any photos, and ask specifically what was excluded and why. Insurers are required to explain a denial or a reduced payout, and a vague answer like 'that's not covered' without pointing to a policy section is worth pushing back on. The declarations page and the policy's coverage sections say what's included, and lining up the denial against that language often shows whether the insurer applied the policy correctly.
Some policies include an appraisal clause, a process built specifically for disagreements over how much damage is worth, separate from whether it's covered at all. Either side can invoke it, and it involves each party hiring an independent appraiser who then agree on a neutral third one if their numbers don't match. It costs something, since each side pays their own appraiser, but it's faster than a lawsuit and it's already built into most policies. Check the policy for an appraisal clause before assuming the only options are to accept the number or walk away from it.
Before the next call
Pull your declarations page and check the appraisal clause and the window for reopening a claim. Line up every photo, receipt, and estimate against it before you accept or dispute a number.
