Flood and Storm

What is flood insurance and why doesn't homeowners insurance cover it?

Flood insurance is a standalone policy designed to cover property damage caused by flooding—something your standard homeowners insurance policy does not cover. This gap surprises many homeowners after a storm, when they discover that rising water, storm surge, and overflowing rivers are explicitly excluded from their homeowners policy. For millions of Americans in flood-prone areas, a separate flood policy is not optional; it is essential.

Why homeowners insurance does not cover flooding

Standard homeowners insurance covers sudden and accidental water damage from inside the home—like a burst pipe or an overflowing bathtub—but it excludes flood damage caused by external rising water. This distinction is deliberate. Flood losses tend to be catastrophic, widespread, and concentrated in high-risk areas, making them difficult for standard carriers to absorb. Congress created the National Flood Insurance Program (NFIP) in 1968 specifically to fill this gap and make flood coverage broadly available.

What flood insurance actually covers

A flood policy generally includes two separate components, each sold with its own coverage limit:

  • Building coverage: Covers the structure itself—foundation, walls, electrical and plumbing systems, HVAC equipment, built-in appliances, and flooring. NFIP building coverage maxes out at $250,000 for residential properties.
  • Contents coverage: Covers personal property inside the home, including furniture, electronics, clothing, and portable appliances. NFIP contents coverage maxes out at $100,000 and is settled on an actual cash value basis.

Private flood insurers often offer higher limits and additional features, such as replacement cost for contents, loss of use coverage, and lower deductibles than the NFIP provides.

Who needs flood insurance

Homeowners in FEMA-designated high-risk flood zones are typically required by their mortgage lender to carry flood insurance. But flooding is not limited to high-risk zones—about 25 percent of flood claims come from properties outside of high-risk areas. Heavy rainfall, inadequate drainage, and rapid snowmelt can cause flooding almost anywhere. Waiting until a storm is approaching is too late; most policies include a 30-day waiting period before coverage takes effect.

NFIP vs. private flood insurance

The NFIP remains the most common source of flood coverage, but private insurers have expanded significantly in recent years. Private policies can offer broader coverage, faster claims handling, and premiums that are sometimes lower than NFIP rates. The right choice depends on your property's risk level, current NFIP rate under Risk Rating 2.0, and the coverage features that matter most to you.

What Truscott recommends

Many homeowners assume they are covered for flood damage until it is too late to do anything about it. Understanding exactly what your current policies do and do not cover is the first step. A Truscott coverage review will evaluate your flood risk, compare NFIP and private flood options side by side, and make sure you have the right building and contents limits in place before the next storm season.

How does a hurricane deductible work on a Florida homeowners policy?

Florida homeowners policies include a separate hurricane deductible that functions very differently from a standard deductible. Learn how it triggers, how it is calculated, and what it means for your out-of-pocket costs after a named storm.

What conditions actually trigger your hurricane deductible?

Your hurricane deductible does not activate automatically with every storm. Specific policy-defined trigger conditions determine when it applies — and understanding them helps you plan your out-of-pocket costs before a storm arrives.
