Give notice of the loss to the insurance company or the insurer's agent/company.
Ask the insurance company what to do about the immediate needs of the dwelling, such as covering doors, windows, and other exposed areas, and pumping out water.
Ask your insurance agent/company what actions are required of you. Some policyholders may be required to make an inventory of damaged personal property showing in detail the quantity, description and how much you paid for the items.
