HailTrace is a real-time hail tracking service providing meteorologist-verified storm event data with property-level impact mapping. It is the primary data source for automated storm lead generation systems used by roofing contractors, restoration companies, and public adjusters. Unlike radar apps or free weather services, HailTrace provides verified hail size measurements, storm path boundaries as GeoJSON polygons, and property-level impact probability — the specific data required to build an automated property targeting pipeline.
What HailTrace Actually Provides
The HailTrace API returns storm events with: meteorologist-verified hail size in inches (not estimates — actual verified measurements), maximum wind speed associated with the event, the storm swath boundary as a polygon that can be used to query which properties were inside the damage zone, estimated property count within the swath, and event date and time. This data is available within minutes of storm verification — fast enough to trigger an automated outreach pipeline before competitors even know the event occurred.
How the API Fits Into an Automation Pipeline
The HailTrace API is the trigger for the entire storm lead system. A scheduled Make.com scenario queries HailTrace every 30 minutes for new events meeting the configured threshold (typically 1 inch or larger) in the contractor's target territories. When a qualifying event is returned, the scenario automatically passes the swath polygon to ATTOM Data to pull affected properties — and the pipeline continues through skip tracing, scoring, and outreach without any human intervention.
