Insurance claims after a flood turn on evidence. Most of the useful evidence has to be collected before the flood, not after. Here is the short list.
Nobody prepares an insurance file for a flood that has not happened. Then it happens, and the claim turns into an argument about what the property was worth, what was in it, and whether the damage came from the covered peril.
The work that makes a claim go smoothly is almost all done in advance, and it takes an afternoon.
1. Read the policy for the exclusions, not the headline. Many Philippine property policies cover fire as standard and treat flood, typhoon, and earthquake as add-ons, sometimes called an extended coverage or catastrophe endorsement. Confirm in writing which perils are actually included and what the limits and deductibles are. The related read is what calamity insurance usually excludes.
2. Photograph the property while it is dry and intact. Every room, every wall, the exterior, the roof, the perimeter. Date-stamped. Store them somewhere that is not in the house.
3. Keep receipts for anything substantial. Appliances, furniture, the aircon, the electrical rework. A pile of receipts in a folder is dull and it is the single most useful thing in a claim.
4. Keep your hazard screening. A report that shows the mapped flood susceptibility at your coordinates, dated before the event, is a clean piece of documentation about the property's known exposure. It also tends to concentrate the mind when you are choosing coverage.
5. Write down the pre-existing damage. Cracks, damp patches, an old leak. Recording them honestly beforehand stops them from being used later to reduce the claim.
Cause of loss. Insurers distinguish between water that entered because of the covered peril and water that entered because of a maintenance failure, like a blocked gutter or a roof that was already leaking. Photographs of the property in good condition beforehand deal with most of this.
Value. Without receipts, you are negotiating from memory against a schedule. With receipts, you are presenting a document.
Insurers price on exposure, and a property in a mapped high susceptibility zone is not the same risk as one outside it. Knowing where you sit lets you buy the right cover rather than the default cover, and it stops the surprise that arrives when a claim is declined for a peril you assumed was included. The wider version is in how a property's hazard profile affects insurance cost.
This is general guidance, not insurance advice, and policies differ. Your insurer and your broker are the authority on what your specific policy covers. A hazard screening tells you the mapped exposure at your coordinates. It does not set premiums, adjudicate claims, or substitute for reading your own policy.
