Roofers who call first book first. The rest call back a signed contract.

The problem

You're not losing to better roofers. You're losing to earlier ones.

The storm lands at 2. Homeowners are outside by 6, dialing by 7. By 9 the crews who answered are booked three weeks deep — and your phone rings only to tell you they already signed.

You've seen this movie. So has your competition.

Everyone saw the storm. Only you saw the doors.

The house, not the block

Parcel-level impact scoring across the whole swath. No more canvassing a zip code and hoping.

Addresses ranked by claim certainty

Sure things first

Old roof, big hail, high value. Ranked so you knock the certain claims before the coin-flips.

Property record showing owner, roof age, value and phone number

Know who answers

Owner, value, occupancy. A landlord in Arizona is a different call than a homeowner in the kitchen.

The number, when you want it

Unlock the homeowner's phone and call before you knock. We only charge when we actually find it.

How it works

One storm, start to signed.

Hail hits

We're already watching the cell. Radar, hail size, and swath geometry land the second the storm does.

Your list is built

Every parcel inside the swath is matched to a roof, an owner, a value, and a claim-certainty score.

You're at the door

You call the 90s before anyone else has a list. By the time the trucks roll in, you're signing.

Proof

Crews that stopped guessing.

“We knocked 50 doors to find 10 real ones. Stormknock hands me the 10 before I leave the truck.”
