Denver · Front Range · May–Oct
A message 30–60 minutes before hail reaches your exact address — time to move the car, close the garage, cover the garden. No app to install.
We'll only message you when it matters. Check your email to confirm — and forward this page to whoever parks next to you.
One street address. We watch a precise point — not your whole county — so you only hear from us when it's actually your sky.
The same NOAA hail-detection data forecasters use, re-checked every 2 minutes from the first cell of the day to the last.
A clear message with arrival time and expected size, 30–60 minutes out. Enough warning to act, honest when we're not sure.
We alert from quarter size up — the point where paint, glass, and shingles start losing.
Most apps forward county-wide warnings — you get buzzed for a storm 30 miles away and learn to ignore it. We watch one point: yours. Fewer messages, each one worth reading.
No. Always follow National Weather Service warnings and take shelter when told to. HailPass is a convenience layer built on public NOAA data — it protects your stuff, the NWS protects you.
Yes, and we'll say so plainly. Radar estimates hail; it doesn't guarantee it. We'd rather you take a two-minute walk to move the car for nothing than skip the warning that mattered. After each storm we ask what actually fell — your replies make the next alert sharper.
Send you alerts. That's it. It's never sold, shared, or used for marketing, and you can delete it anytime from the link in any message.
No. We're not roofers, we don't sell leads to roofers, and nobody will knock on your door because of us. Most hail alerts online exist to time a sales pitch after the storm — ours exists to warn you before it.
