Stormchasers subscribe to hail tracking services which tell them roughly where hail has hit, and they have computer printouts which show the bands of hail coverage with approximate sizes of hail.

This brings in the Out of State companies who come into town, some of them with as many as 50 salesmen who set up base to come and work the storm.

Many of these companies operate under their own name, but many also operate under license or under some form of agreement with local roofing companies, that give them cover.
