THOR Storm Mapper vs. HailSpectrum: Free Lookup or Paid Workflow?

HailSpectrum handles free public lookups. THOR turns storm research into a repeatable contractor workflow with Market Priority, replay, reports, alerts, and built-in canvassing for imported or map-created leads.

Disclosure: THOR publishes this comparison and competes with HailSpectrum. Product details were reviewed on September 11, 2026. Competitor packaging can change, so check the linked official source before purchasing.

Why THOR wins for roofing teams

THOR is built for roofing teams that use storm research every week and need Market Priority, replay, reports, alerts, built-in canvassing, and one persistent workspace.

What HailSpectrum sells beyond THOR

HailSpectrum is a free public lookup with ZIP search, live warning and radar context, older NOAA report history, and an informational download. It does not replace THOR’s saved, monitored, exportable contractor workflow.

What HailSpectrum sells

Why THOR is the stronger value

  • THOR connects Timeline replay, swaths, reports, exports, alerts, and saved leads in one account instead of treating each lookup as a separate task.
  • CSV and KML exports let a team move filtered storm events into its own spreadsheet, map, CRM, or canvassing workflow.
  • Lead Storm Monitor imports lead lists, creates map pins, tracks dispositions, opens call/drive actions, and keeps Storm Hits for follow-up.
  • The 14-day no-card trial lets a team decide whether those workflow tools are worth paying for while keeping HailSpectrum available for free lookups.

Bottom line: choose THOR

Choose THOR when storm research is part of the business. For $34 per month, Market Priority, replay, reports, alerts, and built-in canvassing stay together in one account. HailSpectrum is free, but it is a lookup tool rather than the field workflow THOR provides.
