What to Do in the First Hour After Storm Damage
The actions that matter in the first hour: secure the property if safe to do so, document the damage with photos, file the insurance claim, and call a restoration crew that can dispatch immediately. The actions that hurt the claim: signing AOB paperwork from a storm-chase contractor, throwing damaged contents away before documentation, attempting permanent repairs before the carrier has had a chance to inspect, or letting the property sit exposed because "the contractor will be here tomorrow."
For roof openings, get a tarp up if it is safe. For broken windows, board the opening to prevent further weather + animal intrusion. For interior water from a roof leak, place buckets under active drips and move what you can save away from the path of travel. Don't try to lift wet sheetrock yourself — it crumbles and makes the cleanup worse.
Photograph the loss in its current state — wide shots, close-ups, anything visible from the source of intrusion to the damaged contents. Before-photos are the foundation of the insurance scope. Without them, the adjuster has no basis to evaluate what was there before the loss.
