How Tariffs Could Increase Your Flood Insurance Cost (And What You Can Do About It)

Have you noticed your flood insurance premium creeping up — and no one can explain exactly why?

What if the real culprit wasn’t just flood zone changes or climate risk, but something as far-reaching as international trade?

In this article, we’ll show you how tariffs — those taxes on imported building materials like steel and lumber — directly impact your replacement cost value (RCV) and, by extension, your flood insurance premium.

You’ll learn how tariffs influence construction inflation, which homeowners are most vulnerable to cost spikes, and what proactive steps you can take today to reduce the financial strain.

What Are Tariffs and How Do They Affect Building Costs?

Tariffs are taxes placed on imported goods, often as a response to international trade policies or to protect domestic industries. While they may seem like a distant issue, their effects ripple directly into the U.S. housing and insurance markets.

For example, tariffs on Canadian lumber in 2017-2018 led to price increases of up to 30% on framing materials. More recently, tariffs on steel and aluminum have added thousands of dollars to the cost of rebuilding a typical home.

When building materials become more expensive, construction costs rise. And since flood insurance,  particularly private and some NFIP Risk Rating 2.0 policies, factors in the cost to rebuild your home, your insurance premiums often follow suit.

How Building Cost Increases Impact Flood Insurance

Your Replacement Cost Value (RCV) is the estimated price to rebuild your home using similar materials at today’s prices, not what you paid for it originally.

As tariffs increase material costs, insurers adjust RCVs upward to reflect current rebuilding costs. This can significantly affect:

• Private flood insurance rates (which rely heavily on RCV)
• NFIP Risk Rating 2.0 policies, which now consider home characteristics and rebuilding data

In other words, if it costs more to rebuild your home, you’ll pay more to insure it.

Which Property Owners Are Most Affected by Tariff-Driven Cost Increases?

If you're in one of the following categories, rising material costs due to tariffs could disproportionately affect your flood insurance premium:

• Newly Built Homes: The newer your home, the more accurate (and higher) the RCV is likely to be.
• Homes with Full RCV Coverage: Unlike actual cash value (ACV) policies, RCV-based coverage doesn't factor in depreciation.
• Commercial Properties: Larger buildings mean more materials — and more exposure to rising costs.
• Coastal or High-Risk Flood Zones: Properties in AE or VE flood zones often face stricter rebuilding guidelines and higher insured values.

What You Can Do to Minimize the Impact on Your Flood Insurance

Fortunately, there are several strategies you can use to reduce how much rising building costs impact your flood premium:

• Review and Adjust Your Coverage: Ensure your RCV isn’t overinflated or outdated.

• Use Elevation Certificates: Especially in NFIP policies, these can lower your rate if your property is above base flood elevation.
• Compare Private vs. NFIP: Private insurers may use different methods to calculate RCV and offer better rates.
• Schedule a Flood Insurance Review: A licensed flood expert can assess your policy against today’s costs and recommend savings strategies.

Key Questions to Ask Your Agent About Flood Insurance and Tariffs

Empower yourself by bringing these key questions to your next policy review:

• “Is my RCV affected by current construction costs and tariffs?

• "Can we adjust the deductible or dwelling limit to better manage premiums?"
• “Would private flood insurance offer more flexible RCV calculations than NFIP?”

The more informed your questions, the better positioned you’ll be to make cost-effective choices.

You now understand that tariffs on imported construction materials can silently drive up the cost to rebuild your home, and that means higher flood insurance premiums.

If you've been frustrated with unexplained premium increases, this hidden factor may be the missing piece.

The good news? You can take control. Start with a flood insurance review, compare policy types, and make sure your coverage is aligned with real—not inflated—rebuild costs.
