Target the swath
Identify the part of the storm where hail intensity and track alignment make the map useful for canvassing, field follow-up, and inspection routing.
Hail swath maps
Hail swath maps: understand the estimated hail path.
A hail swath is the estimated area hail crossed during a storm. Learn how to read radar-indicated hail size bands, compare them with individual hail reports, and use the footprint to prioritize inspections—not to confirm damage at a property.
How to read a hail swath map
- Check the event date and area. A past storm footprint is not a forecast or a warning for today.
- Read the size legend. Bands represent estimated hail diameters; a peak size does not mean every location experienced that size.
- Compare observations. Individual hail reports provide location-specific context but do not cover every neighborhood.
- Use exposure as an estimate. Housing units within a mapped band are potentially exposed—not confirmed damaged roofs.
A warning polygon covers an area at risk; a hail report marks an observation; a swath estimates the storm's hail footprint. Use each for its own purpose, and verify property conditions on site.

Reduce wasted drive time
Instead of working an entire metro blindly, focus on the mapped hail swath and surrounding neighborhoods first.
Clear storm context
Each storm page includes date, affected areas, hail size, and event detail so the swath sits inside a full storm narrative.
How teams use these maps
Open storm libraryFocus on neighborhoods inside the swath
Hail swath maps help teams prioritize the part of town most likely to have seen damaging hail instead of chasing broad regional alerts.
Use swaths with storm detail
Open any storm page to review the mapped footprint, hail size, event timing, and local area labels together.
Keep comparing storms
Search multiple hail swath maps across states and dates when you need a cleaner picture of recent opportunities.

Frequently asked questions
What is a hail swath map?
A hail swath map highlights the path or footprint where hail tracked during a storm, helping users distinguish the likely impact zone from the larger warning area.
Why do roofers care about hail swaths?
Roofers use hail swath maps to prioritize neighborhoods, reduce wasted drive time, and focus inspections on areas more likely to have been hit.
Can I compare multiple hail swath maps?
Yes. HailMapr's storm library lets you browse and compare multiple storms across dates, states, and local areas.
How is a hail swath different from a hail report?
A report records a hail observation at a particular place and time. A radar-derived swath estimates a broader footprint between observations. A missing report does not establish that no hail fell, and a mapped swath does not confirm damage to every property inside it.
