Corelogic Hail Sizes

Trading Term

CoreLogic hail size data quantifies the diameter of hailstones observed during storm events and is used to estimate the severity of hailstorms for insurance and risk management purposes. CoreLogic, a prominent provider of real estate and property data, collects hail reports and radar estimates to model impact zones and probable damage levels. Hail sizes are typically categorized in inches, with thresholds for minor (e.g., 0.5”), moderate, and severe (e.g., 2”+) hail events.

Larger hailstones have a disproportionate effect on insured losses, particularly for residential roofs, vehicles, and commercial structures. Therefore, tracking hail size and spatial extent allows insurers to quickly triage claim volumes and reserve capital. Additionally, historical hailstorm data is incorporated into actuarial models used to price homeowner policies and develop new risk-based insurance products.

Beyond insurance, CoreLogic hail data is used by construction firms, agricultural operations, and emergency planners. It enables better materials planning, damage prevention measures, and response coordination. As climate variability increases the frequency and intensity of severe convective storms, hail modeling has become a critical part of financial resilience planning for communities and insurers alike.
