Verified hail reports for any address, in seconds
After a storm, the roofer with documentation wins the door. Rooftops AI now includes verified hail history in every full roof report: ground-truth NWS storm reports for that exact address — hail sizes, dates, damaging wind gusts, even tornado reports — each one measured in miles from the roof you're standing in front of. No separate storm-data subscription, no guessing from a radar map. Type the address, and the storm story is in your hand before you knock.

Hail size damage checker
Pick a verified hail size and see what it typically means for a roof.
Widespread bruising and fractures likely; claims commonly approved with documentation. Vents and flashings visibly damaged. Damage depends on shingle age, pitch, and wind; an on-roof inspection is the proof that matters.
How it works
Enter the address
Search any US address. We pull verified NWS Local Storm Reports — filed by trained spotters and officials through National Weather Service forecast offices — for the area around that exact property.
See the storm story
Hail days, maximum hail size, most recent hail date, and peak wind gust at a glance, plus a dated event list with each report's distance from the roof.
Knock with evidence
Open the conversation with documented facts: "1.75-inch hail was verified two miles from your roof last September." Then back it with measurements, an inspection, and a proposal from the same report.
What you get
Verified, not modeled
These are ground-truth NWS Local Storm Reports — the same events insurers and adjusters recognize — not radar estimates that never touched the ground.
Distance from that exact roof
Every hail, wind, and tornado report is measured in miles from the property pin, so you know whether the storm hit the neighborhood or just the county.
Built into the full roof report
Storm history sits alongside satellite measurements, condition analysis, and the cost estimate — one report, one conversation, one close.
Storm canvassing, organized
Pair hail reports with door-knock statuses and household notes: work a storm-hit street, mark every door, and export your canvassing list to CSV.
What counts as claim-worthy hail
The number adjusters anchor on is one inch, roughly quarter size. At that diameter, hail carries enough energy to bruise asphalt shingles: the impact crushes granules into the mat and fractures it, even when the surface looks intact from the ground. Below one inch, damage is possible on aged or brittle shingles but harder to attribute. Above 1.5 inches, damage on an asphalt roof is close to certain, and soft metals around the home (vents, gutters, window wraps) will usually show it too.
Size alone is not the whole story. A ten-year-old shingle takes damage that a two-year-old shingle shrugs off, wind-driven hail hits harder on the windward slopes, and a roof can take real damage from a storm the homeowner slept through. That is why the verified event record matters more than memory: about a third of hail claims list a wrong loss date, and carriers deny on that mismatch alone.
Verified reports vs. radar-estimated hail maps
Most hail maps sold to roofers are radar-derived: an algorithm infers probable hail size from reflectivity data. Useful for canvass planning, but an adjuster can wave it off, because radar-estimated size at altitude is not ground truth. NWS Local Storm Reports are different. Each one is an observation filed through a National Weather Service forecast office by trained spotters, emergency managers, or law enforcement: a time, a location, and a measured size that entered the federal record.
That provenance is why storm history in Rooftops AI is built exclusively on verified reports and why each event is shown with its distance from the exact property. The claim conversation changes when you can say a verified 1.75 inch report was filed 2.1 miles from this roof on a specific date, and then hand over the printed record.
How roofers actually work a hail report
The playbook that wins: pull the address report before the knock, lead with the specific storm date at the door, and book the inspection on the spot. On the roof, chalk and photograph bruises with a size reference, then anchor the claim to the verified date so the carrier's weather review confirms rather than contradicts you. If the homeowner has an older roof with multiple verified events, the story is cumulative damage across documented storms, which is a different and often stronger conversation than a single event.
The filing window makes old storms live inventory. Most homeowner policies allow one to two years from the date of loss, so a verified event from last spring is still a valid claim today. Every address you measure keeps its storm history attached, which turns your report archive into a canvassing list every time a new storm date shows up.

Frequently asked questions
How do I find the hail history for an address?
Enter the address in Rooftops AI and generate a report — verified storm history for that location loads with it, including hail sizes, dates, wind gusts, and each event's distance from the roof.
Is the hail data verified?
Yes. Events come from NWS Local Storm Reports — observations filed by trained spotters, emergency managers, and officials through National Weather Service forecast offices — not radar estimates.
Can I use hail reports in insurance conversations?
That's what they're for. A dated, verified hail event near the property is the starting evidence for a damage inspection and claim conversation. Pair it with an on-roof inspection to document actual damage.
How far back does the storm history go?
Reports cover the past several years of verified storm activity around the property — enough to catch the hail event a homeowner forgot about but their shingles didn't.
How much do hail reports cost?
Hail history is included in full roof reports on every paid plan (from $30/mo billed annually, with a 3-day free trial). New accounts get 3 free roof reports to start.
