THOR Storm Mapper now includes a dedicated Property Storm History Report feature. Type any U.S. address, hit Generate, and within seconds you have a complete NOAA-verified storm record for that property — every hail event, tornado, and wind report within one mile, going back to 2014. The report is formatted as a clean, professional PDF you can hand directly to a homeowner, adjuster, or insurance carrier.
Every report you generate is automatically saved to your account. Open My Reports at any time to see your full library, re-download any report as a PDF, or delete ones you no longer need. There are no per-report fees, no regeneration required, and no expiration — your reports stay on file as long as your subscription is active.
Why Roofing Contractors Use It
The single most powerful thing a roofing contractor can do before knocking on a door is already know the storm history of that property. Walking in with a printed report — showing the homeowner the exact date, hail size, and distance from their address — transforms a cold knock into a credible, data-backed conversation. Homeowners who might otherwise dismiss you as another storm chaser take you seriously when you hand them a document sourced from the National Weather Service.
The report also eliminates the back-and-forth with insurance adjusters. Instead of waiting for the carrier to pull their own data, you arrive at the inspection with the NOAA-verified event record already in hand. Adjusters can confirm the date and severity against their own systems in seconds, and the claim moves forward without delay.
Why Public Adjusters Use It
For public adjusters, the property storm history report is the foundation of every claim file. Insurance carriers require documented evidence that a qualifying storm event occurred at the insured property on or before the date of the reported damage. A NOAA-verified report — showing event type, magnitude, date, and distance from the address — supports that documentation requirement with authoritative government data.
Because reports are saved to your account, you can build a library of claim documentation across your entire client portfolio. Pull up any property's report during a carrier negotiation, share it with an attorney, or attach it to a formal demand letter — all without going back to regenerate the data.
Why Homeowners Use It
Most homeowners have no idea how many storms have hit their property over the past decade. They notice a leak or a few missing shingles and wonder whether it is worth filing a claim. A property storm history report answers that question definitively. If the data shows three hail events over 1.5 inches in the past five years, the homeowner has a clear basis for a professional inspection and a potential claim.
What the Report Contains
Every property storm history report includes a summary header showing the address, state, total event count, maximum hail size recorded, maximum wind speed recorded, and tornado event count. Below the summary is a full chronological event log with one row per storm event, showing the date and time, event type, magnitude, distance from the property, city, county, and the NOAA source identifier. Events are filtered to within one mile of the exact address coordinates.
My Reports — Your Permanent Library
The My Reports page gives you a full view of every report you have generated, sorted by most recent. Each card shows the address, state, risk level badge, event count, max hail size, max wind speed, and tornado count at a glance. From there you can re-download the PDF, re-run the report to pick up any newly published NOAA events, or delete reports you no longer need.
For contractors managing dozens of properties at once, the library is a practical workflow tool. Generate reports for every address on a canvassing route, keep them on file through the claim cycle, and pull them up again if a homeowner calls back months later. The data is always there, always accurate, and always one click away.
