The Michigan Department of Insurance and Financial Services has approved ZestyAI's Severe Convective Storm suite, including the proprietary Z-HAIL™, Z-WIND™, and Z-STORM™ models.

Michigan Faces Rising Losses From Severe Convective Storms

The approval comes as Michigan contends with rising weather-related insurance losses.

According to NOAA’s National Centers for Environmental Information (NCEI), the state has experienced over $5 billion in insured storm damage since 2019, with hail and straight-line winds accounting for the majority of claims. In 2024, a series of intense summer storms alone caused more than $1.2 billion in insured losses.

Why Carriers Need Property-Level Precision

ZestyAI’s AI-driven platform predicts the likelihood and severity of claims from severe convective storms at the individual property level by analyzing the interaction of local climatology with property-specific characteristics. In contrast, most risk assessment models today rely on broader territory or ZIP code-level evaluations, overlooking critical property-level factors. 

Each model is built and validated on extensive real-world claims data and delivers transparent explanations of the key drivers behind every risk score, helping carriers make more accurate underwriting and rating decisions.

How ZestyAI’s Storm Models Improve Risk Assessment

Key capabilities include:

• Z-HAIL: Predicts hail damage risk and claim severity using property-specific attributes like roof complexity, historical losses, and accumulated damage, identifying which homes are most likely to file a claim, even within the same neighborhood. 
• Z-WIND: Combines AI-generated 3D analysis of roof condition, complexity, and potential failure points with local climatology to deliver pivotal insights into property-specific wind vulnerability and severity. 
• Z-STORM: Predicts the frequency and severity of storm damage claims, including hail and wind, examining the interaction between climatology and the unique characteristics of every structure and roof.

What Michigan’s Approval Means for Insurers

“As severe weather becomes more frequent and costly, insurers need tools that keep pace with evolving risks,” said Bryan Rehor, Director of Regulatory Affairs at ZestyAI.

“This approval gives Michigan carriers access to precise, property-level insights that support smarter underwriting and help reduce preventable losses.”

Michigan's approval marks the 17th state to embrace ZestyAI's Severe Convective Storm suite, reflecting increasing regulatory confidence in AI-powered risk models that deliver actionable insights while supporting industry-wide resilience efforts.

With insured losses projected to exceed $30 billion, the recent Los Angeles wildfires rank among the costliest in U.S. history—reshaping how insurers think about risk, resilience, and readiness.

ZestyAI today announced that the Connecticut Insurance Department (CID) has formally approved its Roof Quality solution for use in residential property underwriting.

CID conducted a comprehensive third-party actuarial review of ZestyAI’s model, evaluating methodology, data integrity, and regulatory compliance against its rigorous standards.

What CID’s Approval Means for Carriers

Part of Z-PROPERTY™ , the Roof Quality model enables insurers to assess and price roof risk with unmatched accuracy.

By combining 3D property analysis, high-resolution aerial imagery, and AI trained on extensive real-world data, the platform replaces subjective or incomplete assessments with objective, property-specific intelligence.

The model classifies roofs into five standardized condition levels, helping insurers assess property risk with greater precision. It distinguishes between surface-level wear and structural issues, flagging meaningful signs of deterioration such as missing shingles, tarps, or water pooling.

Bryan Rehor, Director of Regulatory Affairs at ZestyAI, said:

“Roof condition is one of the strongest predictors of loss, yet historically one of the hardest to assess without costly inspections. This approval affirms the accuracy, fairness, and transparency of our approach and reflects our broader commitment to aligning innovation with consumer protection.”

How ZestyAI’s Roof Quality Model Improves Risk Assessment

ZestyAI maintains active engagement with the National Association of Insurance Commissioners (NAIC) and state-level departments to ensure its models meet evolving standards for fairness, transparency, and consumer protection.

By proactively filing through in-house Rating and Advisory Organizations, ZestyAI ensures its models meet the strictest regulatory standards before reaching the market. 

ZestyAI’s models are trusted by regulators and insurers to assess risk in the nation’s most climate-exposed regions with Z-FIRE, ZestyAI’s wildfire risk model, approved by regulators in all western states. Its Severe Convective Storm suite is approved in 16 states across the Midwest, Great Plains, and South.

ZestyAI today announced a new partnership with Farmers and Mechanics Mutual Insurance Company of West Virginia (FMIWV) to strengthen underwriting accuracy and improve risk-based pricing.

Why Accurate Roof Data Matters More Than Ever

Roof claims are the leading driver of insurance losses, yet many carriers still depend on self-reported data, which can be unreliable, or physical inspections, which are costly and hard to scale. Recent research shows that 15% of roofs are at least eight years older than reported, highlighting the need for more reliable, data-driven alternatives.

To address long-standing challenges in accessing reliable property insights, FMIWV selected Z-PROPERTY™.

Why FMIWV Chose Z-PROPERTY

Dan Otto, Senior Vice President and Chief Financial Officer at FMIWV, said:

"After evaluating several options in recent years, we chose ZestyAI based on their strong coverage and ease of implementation. Getting started using the technology was easy. We’re particularly focused on using their property insights to provide additional underwriting information for new business and renewals.”

ZestyAI’s advanced insights help FMIWV:

• Identify high-risk properties early to prioritize mitigation and prevent losses
• Enhance risk selection and pricing precision with objective, property-level data
• Reduce inspection costs and turnaround time by minimizing the need for on-site assessments
• Streamline straight-through processing for low-risk properties to improve efficiency and speed to bind
• Reduce premium leakage by aligning pricing with actual exposure

“FMIWV is showing how regional carriers can lead with data-driven underwriting that improves operations and elevates the customer experience,” said Attila Toth, Founder and CEO of ZestyAI.

“By grounding decisions in reliable, property-level data, they’re improving efficiency, reducing risk, and raising the bar for underwriting and rating precision.”
