Flood damage is not covered by standard homeowners insurance. With floods being the most common and costly natural disaster, understanding flood insurance is essential for protecting your home.

Why You Need Flood Insurance

Important facts:

  • Standard home insurance excludes flood damage
  • Just 1 inch of water can cause $25,000+ in damage
  • 20-25% of flood claims come from low-risk zones
  • Floods can happen anywhere it rains
  • Federal disaster aid is usually a loan, not a grant
