Master SCS exposure with risk scores
Severe convective storm losses continue to surge. By replacing outdated regional averages with property-level hazard risk scores, underwriters can accurately quantify hail, wind, and lightning exposure to protect balance sheets.

Transform underwriting with risk scores
Property insurance underwriters face severe convective storms rivaling hurricane losses. Cotality provides granular, high-fidelity hazard risk scores to evaluate hail size, wind, and lightning frequency at specific property locations.

Precision risk scores for severe storm risk
Cotality Hail™
Accurate property-level hail risk assessments powered by actuariallycredible, Average Annual Loss (AAL) metrics for precise underwriting and riskmitigation.
Hail risk score
Delivers property-level annual event probabilities and includes a Supplemental Hail Claim Risk Score to forecast claim filing likelihood with high-fidelity precision.
Wind resiliency score
Predictive solution evaluating catastrophic hurricaneand convective wind impacts at the property level to generate precise frequencyand severity ratings.
Hail Insight®
Provides a precise three-year look back at historical hail activity, identifying exact event occurrences and stone size distributions using proprietary hail verification technology.
Wind risk score
Features distinct 1–100 scores for tornadic, straight-line, and hurricane-force winds using high-resolution historical windstorm observations and verification data.
Lightning risk score
Evaluates recorded lightning strike frequency and strike density to help insurers accurately assess sub-peril exposure and refine policy pricing.
Address-level severe storm risk scoring

Severe Convective Storms no longer represent localized events, they are primary drivers of portfolio loss. Cotality equips underwriters, actuaries, and risk managers with granular, location-level risk scores that eliminate guesswork and strengthen risk selection. By leveraging high-fidelity weather verification and property-specific hazard scores, carriers can confidently screen submission quality, price volatile perils accurately, and manage aggregate exposure across expanding geographic footprints.
FAQ
How do property-level SCS risk scores protect underwriting margins compared to regional averages?
Property-level risk scores evaluate exact address vulnerabilities rather than broad regional averages. This precision prevents loss ratio leakage caused by rising home values, eliminates underwriting blind spots, and enables carriers to accurately price hail, wind, and lightning risks.
How can exposure leaders leverage property-level risk scores to prevent catastrophic accumulation?
Risk leaders use address-level risk scores to identify neighborhood concentration risk and aggregate exposure. This granular visibility allows insurers to set strict portfolio limits and safely manage geographic expansion in high-density, storm-prone regions like Texas and Colorado.
How do property-level risk scores support actuarial teams in building defensible rate structures?
Actuaries leverage property-level risk scores and annual event probabilities to align loss models with actual exposure. Replacing coarse geographic estimates ensures accurate expected loss calculations, refined risk segmentation, and defensible rate filings for regulators.
What scientific data validates the accuracy and fidelity of these SCS risk scores?
Severe Convective Storm (SCS) risk scores are validated using proprietary hail verification technology, high-resolution windstorm observations, and recorded lightning strike data. These objective observational metrics provide catastrophe modeling teams with transparent, scientifically rigorous risk scores to refine portfolio simulations
