The roof stock
Ofallon skews new — median build year 1997. The play here isn't tear-offs on every corner; it's storm response, repairs, and being the name the street already knows when the first replacement wave lands.
The street math
At roughly 1,794 homes per square mile, Ofallon is classic suburban density. Around a typical Ofallon job site, the 100 nearest homes sit within about 450 feet — we measured it against our address map, not a ZIP-code guess. That's a one-street radius: the people who watched your crew work all week.
The customer
The median Ofallon home is worth $314,700, up a steady 4% across the last two ACS five-year estimates — owners here are invested, not flipping. 80.3% of occupied homes are owner-occupied, so the person reading the card is the person who signs the contract.

Roofing marketing in Ofallon, answered with numbers.
78,363 mailable residential addresses carry a Ofallon mailing address in the Quillus map (81 Census block groups). You don't mail all of them — Quillus finds the 100 homes physically closest to a job you just finished and mails only those, so every card lands on a street that watched your crew work.
Close. We sampled real Ofallon addresses against our map: the 100 nearest homes around a typical job site sit within about 450 feet (138 meters). That's the same street and the next one over — not a ZIP-code blast across town. That distance is the campaign's proximity radius — the working unit of proximity mail marketing.
It's a repair-and-storm market more than a tear-off market: the median home went up in 1997. The roofers who win here are the ones the street already knows when the first replacement wave arrives.
The median Ofallon home is valued at $314,700; up 4% between the two most recent ACS five-year estimates; 80.3% of occupied homes are owner-occupied; median household income is $111,400. In plain terms: real equity in the house, and the decision-maker usually lives under the roof you would be replacing.
Inside 24 hours. Finish the tear-off, snap the photo, pick the 100 nearest homes on the map, and the cards are printed and in the mail stream the same day — in Ofallon mailboxes while your sign is still in the yard.
Two places: the Quillus address map (155M+ geo-located U.S. addresses — the Ofallon home count and street-distance figures are measured from it directly) and the U.S. Census Bureau's American Community Survey 5-year estimates (2024 vintage) for home values, build years, and occupancy. Figures are city-level aggregates, refreshed when new ACS data ships.
Your next roof in Ofallon is one street away.
