Severe Weather Property Recovery Plan

Immediate Safety Measures

  • Seek Indoor Shelter: Move immediately inside a structurally sound building, staying on the lowest floor away from windows.
  • Secure Loose Property: Bring lightweight outdoor objects, furniture, and trash bins inside to avoid wind-borne projectile damage.
  • Disconnect Sensitive Gear: Unplug core electronic infrastructure to shield appliances from lighting strikes or sudden grid drops.

Post-Storm Insurance Preparation

  • Document structural damage: Take immediate photos of any visible effects of the storm, no matter how small or minute the damage may seem. Clear photographic evidence anchors your eventual claim recovery.
  • Mitigate safely: Policyholders generally have a responsibility to mitigate further damage. Handle emergency temporary fixes (like shutting off a main valve or tarping a broken window) if safe to do so. Do not attempt permanent structural repairs until an official inspection occurs.
  • Log milestones: Keep a running timeline of the incident, damage discovery dates, and interactions with your insurance company to keep the claim organized.
