New AI-powered solution enhances property risk assessment by accurately determining Roof Age across the contiguous US.

ZestyAI, the leading provider of climate and property risk analytics solutions powered by Artificial Intelligence (AI), announced today its partnership with Donegal Insurance Group® on a project that utilizes its new Roof Age solution for Donegal’s existing Personal Lines book of business.
Through the project, Donegal, a Pennsylvania-based regional insurance carrier, leveraged ZestyAI’s Roof Age solution to populate Homeowner policy renewals where roof age was absent.
ZestyAI’s Roof Age solution pinpoints the age of a roof using data from both building permits and historical imagery going back 20-plus years. This unique approach allows the company to determine the validated age of each roof with over 90 percent accuracy and nearly 100 percent coverage across the contiguous US.
“Accurate roof age information is critical for properly assessing and pricing risk,” said Hank Narvaez, Vice President of Personal Lines Product Development at Donegal. “ZestyAI’s Roof Age solution was a clear choice for us due to its solid coverage length of historical imagery. By leveraging both building permit data and aerial imagery, we gain added confidence in our underwriting and rating decisions.”

“Blind spots in assessing property risk can be very costly for insurers,” said Attila Toth, Founder and CEO of ZestyAI. “Roof claims stand as the primary driver of insurance losses, yet many carriers continue to rely on unvalidated roof age information. We are excited to partner with Donegal to enhance their risk assessment with the most accurate roof age solution on the market.”
Roof Age is one part of a complete range of ZestyAI products designed to evaluate roof-related risk. Other solutions include Digital Roof, which creates a digital twin of every structure in the US for unparalleled insights on condition, complexity, and potential points of failure, as well as peril-specific risk models such as Z-HAIL, Z-WIND, and Z-STORM.
