The Ground Impact advantage
A clearer starting point after the storm.
Ground Impact helps narrow a broad hail footprint into areas to prioritize—so your team can spend less time choosing where to go and more time inspecting.
Plan while storms develop
HailMapr Live refreshes as new data is processed, including Ground Impact when available. Review the map's update time; active maps evolve as the storm unfolds.
HailMapr Canvass
Turn a target area into saved doors, assigned reps, inspection appointments, and follow-up. Keep the work connected to the storm.
Ground Impact estimates hail exposure, not confirmed roof damage. Use it to prioritize inspections—not to promise a damaged roof or an approved claim.
