FEMA Disaster Assistance: 1-800-621-FEMA
FEMA Process Info: After you fill out your online application, you will receive an email telling you that an inspection is required. FEMA will send an inspector to your property to inspect it and verify damages, prove occupancy (driver's license, utility bill), and prove ownership (title or insurance), car damages (proof of liability insurance for your car, title and registration would be good to have on hand). Pictures can help if the work has been done already, and if you can get pictures, do so.
Document all damage. This is a crucial part of the insurance claims process. Without proper and thorough documentation, your insurer could deny your claim.
