ZestyAI Analysis Reveals 6x Surge in ACV Roof Endorsements as Carriers Shift Risk to Policyholders

Quick Summary

A new ZestyAI study reveals that Actual Cash Value (ACV) roof endorsements have increased six-fold since 2015. Carriers are shifting risk to homeowners by layering restrictions like percentage deductibles and cosmetic exclusions to manage rising catastrophe losses while keeping headline premiums competitive at the point of sale.

How is the Homeowners Insurance Contract Changing?

The modern homeowners insurance policy has undergone a fundamental structural shift over the last decade. Carriers are moving away from traditional replacement cost coverage toward Actual Cash Value (ACV) settlement schedules, which account for depreciation. This shift is most visible among the top 10 US carriers, where ACV adoption surged from 10% in 2015 to 60% in 2025.

• Percentage-based deductibles now appear in 90% of top-tier policies.
• Cosmetic damage exclusions have jumped from 20% to 90% adoption.
• Anti-matching provisions are becoming a standard industry baseline.

By integrating these Actual Cash Value provisions, insurers can offer lower monthly premiums, but the financial burden on the consumer increases significantly when a claim is filed, particularly for roofing losses.

What Geographic Trends Impact Coverage Restrictions?

Carriers are tailoring their risk mitigation strategies based on regional catastrophe exposure. In states prone to severe convective storms, coverage controls are no longer optional endorsements but foundational contract elements. ZestyAI's analysis of 2,000 filings shows that geographic concentration dictates the specific combination of restrictions used.

• Texas: 100% adoption of percentage deductibles and 82% ACV roof schedules.
• Oklahoma: 95% percentage deductibles and 85% ACV prevalence.
• Colorado: 50% of filings now include cosmetic damage exclusions.

This layered coverage approach means a single loss event, such as a hailstorm, may trigger four or more separate restrictions, drastically reducing the net payout to the policyholder.

How Does ZestyAI Technology Support Insurers?

To manage these complex risks, insurers are deploying predictive AI models and regulatory intelligence platforms like ZORRO Discover™. These tools allow carriers to assess property-level vulnerability for perils like wildfire and wind. For example, DUAL North America recently expanded its use of Z-FIRE™ and Z-STORM™ to strengthen underwriting precision across its US portfolio.

“Two policies can look nearly identical at bind and behave very differently at claim time. The difference is that one may achieve a lower premium by layering restrictions that shift more risk back to the policyholder. Consumers naturally focus on the price they pay today, while the cumulative impact of a percentage deductible, an ACV roof settlement schedule, an age-based trigger, and a cosmetic exclusion often doesn't become clear until a loss occurs. That's why a decade-long trend like ACV adoption jumping six-fold matters: the economics of a roof claim under those policies can look fundamentally different.” said Stephanie Kuczynski, Director of Risk Analytics at ZestyAI.

FF NEWS TAKE:

This report from ZestyAI highlights a stealth industry pivot that moves the needle by redefining the value proposition of insurance. While Actual Cash Value adoption helps carriers maintain solvency amidst climate volatility, it creates a massive "protection gap" at the moment of truth. The industry is effectively trading long-term consumer trust for short-term price stability, a trend that will likely invite increased regulatory scrutiny as claim-time disappointments mount.
