After a storm, two separate things happen. You gather a record of what the storm did to your property. Then, if you carry a policy that responds to it, your insurer inspects and decides what is covered and for how much, under the terms of that policy. This guide is entirely about the first thing, because it is the part you control and the part that is easy to do badly.
A clean, dated record does one job well: it preserves the truth of the roof before repairs erase it. It is not a promise about a settlement, and no honest contractor can make one. Anyone who guarantees an insurance result, or offers to make your deductible disappear, is telling you something about themselves, not about your roof.
Build the record for its own sake. Photographs tied to locations, a timeline, and preserved materials are useful to an adjuster, to a second contractor, and to you, whatever any single decision turns out to be.
For how a storm response actually runs, and what carrier-ready documentation involves, see storm restoration. This guide stays on your side of that process: the evidence you can gather before anyone arrives.
