What Is Hail Swath Data With Property Addresses?
Hail swath data with property addresses means the storm's radar-derived footprint (which properties are physically inside a confirmed hail path, and at what size band) is matched against real parcel and address data — so instead of a shape on a map, you get a list of addresses that were actually in the storm's path.
The Two Layers, Combined
- Swath layer: MRMS MESH-derived hail-size polygons, one per storm date and size band, drawn directly from radar — this is the "where and how big" layer. Hail size is a radar estimate, not a physical inspection.
- Point layer: NOAA Storm Events and SPC storm reports, which confirm hail was observed/reported at specific points and times.
- Property layer: Parcel and address data matched against the swath polygon to determine exactly which properties sit inside it.
txhailleads carries the match one step further by checking each address inside the swath against building permit records — surfacing the ones with no re-roof permit filed, which is the actual lead.
Every lead is a parcel inside a confirmed hail swath with no roof permit filed since the storm. We check the permit record, we do not estimate roof age.
Why Address-Level Matters
A swath polygon on its own tells a roofer "storms hit this general area." Address-level matching tells them which specific properties were inside the hail path, which is what a door-knocking or direct-mail campaign actually needs.

Frequently Asked Questions
- What is hail swath data with property addresses?
- The radar-derived hail-storm footprint matched against real parcel/address data, so you know which specific properties were inside the storm path.
- How is hail swath data different from a storm report?
- A storm report is a point confirmation that hail occurred. Swath data is the full radar-derived polygon showing the storm's footprint and hail-size gradient.
- Can hail swath data be combined with permit records?
- Yes — that combination (swath + permit records) is how txhailleads turns storm data into an unserviced-lead list.
