Roofer FAQ · Costs
Every marketing argument in roofing ends at the same formula: what you spent, divided by the jobs you signed. Most contractors have never run it per channel — and the channels counting on that are the ones the formula embarrasses.

THE SHORT ANSWER
Customer acquisition cost (CAC) is total channel spend divided by jobs signed from that channel. On a $12–15K average roofing ticket, healthy CAC commonly lands in the hundreds of dollars — but shared-lead channels can push it into the thousands once close rates are counted. Demand-first math runs lower: one measured $2,500 campaign on AI-qualified homes signed ~$130K of work.

The formula, with nothing hidden
CAC = everything a channel cost you ÷ jobs it signed. 'Everything' includes the spend you forget: the wages of whoever chases the leads, the fuel for dead-end estimates, the software fee behind the campaign. Roofing's high ticket size forgives a lot of marketing sins — which is exactly why unexamined CAC drifts up for years before anyone notices.
What 'good' looks like — and how to keep it good
Benchmark against your ticket: many residential contractors aim for CAC under 5% of job value — a few hundred dollars on a $12–15K roof. Then defend it: recompute per channel quarterly, include labor honestly, and shift budget toward channels whose CAC holds as they scale. Auction channels inflate with competition; owned demand — lists you scored, households you targeted — is the CAC that compounds in your favor.
Why sticker price and CAC are different animals
1
A $200 shared lead is not $200 — sold to 4–5 contractors, closed maybe 1-in-10, it's a $2,000-per-job channel before fuel and estimating time.
2
A cheap click is not a cheap job — pricey roofing keywords plus modest conversion rates stack into four-figure CAC in competitive metros.
3
A $1.79 opportunity is $1.79 of list — outreach (mail, Home Ads) is the real spend; because every door verifiably needs work, the response — 3–5% on qualified lists — carries the math.
A worked example you can copy
1
Spend — $2,500: scored homes at $1.79 each plus a two-touch Direct Mail Sequence on the best of them.
2
Response — 3–5% of qualified doors raise a hand; Mail Alerts text you each QR scan in seconds.
3
Close — in the measured case, 4 signed jobs → CAC ≈ $625 on ~$130K of contracted work.
4
Compare — the same $2,500 buys roughly 4–16 shared leads at $150–700 each. The auction has to go perfectly to break even.
