Here is the part of the storm-data business nobody on a vendor sales call will tell you out loud:
Inside a typical hail-warning polygon, only about 17% of parcels actually take damage worth a roof conversation. The other 83% are homes the storm flew past, or barely brushed. You paid for them. You will dial them. They will say “we did not have any damage over here.”
That is the 83% tax. Every other property-data vendor charges it, and most of them have built their entire pricing around it. Polygon in, fifty thousand parcels out, here is your invoice.
The storm does not respect the box
It gets worse the longer you look at it. The actual damage swath does not care about the polygon. Hail cores wander. A meaningful chunk of every storm lands outside the warning box entirely — across town, in the next ZIP over, in the adjacent suburb that got cored even harder. So you are paying for the wrong list twice: too much of the polygon, and none of the homes that actually got hit two miles away.
Out-of-state chasers know this. They show up with maps, drive the storm itself instead of the ZIP, and start knocking the streets where shingles are in the yard. By the time a local crew is working off a vendor's ZIP-code download, the chaser has been signing contracts for two days.
Picture the wallet
Same money, two strategies. Twenty calling days, one team:
The broad ZIP pull · $10,000 spent on data
- ~50,000 records bought
- ~15,000 dials, ~12,000 of them on homes that were never hit
- ~25 inspections booked
- ~$400 data cost per booked inspection
The Roofers Radar storm-zone pull · $1,750 spent on data
- ~3,500 records bought, parcel-level filtered to actual damage
- ~3,000 dials, most of them on homes with visible damage
- ~90 inspections booked
- ~$19 data cost per booked inspection
Same team. Same two weeks. 20× the efficiency.And that is before you count the morale cost of the 12,000 dials the broad list burned through with nothing to show.
Built for mortgage brokers vs. built for roofers
Mortgage originators and insurance underwriters do not care where the hail landed. They want ZIP codes. So every legacy property-data vendor is wired around ZIP codes — because the real customer is not you. You are an afterthought sharing the same checkout page.
We are wired the opposite way. The starting point is the storm geometry. The filter is parcel-level damage probability. The list you pull is the list of homes where the conversation opens with “yes, my neighbor's gutters got punched in too” instead of “sorry to bother you.”
That is the whole point. We do not sell polygons. We do not sell ZIPs. We sell the homes that got hit.
Start spending the right way
If your team is still working a ZIP-code dump, you are paying the 83% tax on every dial, every drive, every weekend. That money was supposed to find you a roof — not pay a vendor to sell you 50,000 rows of noise.
Pick the storm. Pick the severity tier. Pull the homes. See the count and the price before you commit. That is what spending smarter looks like — and it is two minutes from now if you want to try it.
