CAC & Metrics · · 9 min
Why does your roofing CAC keep rising even as you generate more leads?

You raise your ad budget. More leads come in. But at month-end your customer acquisition cost (CAC) also went up. It sounds contradictory, but it's more common than you'd think. The problem isn't quantity; it's follow-up quality.
The inflated CAC cycle
When marketing generates more leads without a qualification system, sales receives more noise. The team spends time on prospects with no insurance, non-owners, or no decision timeline. The good leads wait in line because nobody prioritizes them.
- More budget → more leads of all kinds.
- Sales doesn't qualify; inspects anyone.
- Good leads wait while bad leads consume time.
- Close rate drops.
- Marketing interprets 'we need more leads' and raises the budget again.
In sales operations studies, this lack of feedback between sales and marketing can raise CAC by up to 300%. That means you pay three times more per customer than necessary.
"A high CAC is rarely fixed with more budget. It's fixed with better follow-up."
How to break the cycle
- Qualify leads before inspecting: owner, insurance, decision-maker, storm date.
- Send quality feedback to marketing every week.
- Stop campaigns or keywords that produce leads that never close.
- Measure CAC by channel, not just CPL.
- Raise contact rate and close rate before raising budget.
Metrics that prevent inflated CAC
| Metric | Suggested target | Why it matters |
|---|---|---|
| Contact rate | > 70% | If you don't contact, you can't close. |
| Cost per inspection | < $600 | Avoid inspecting cold leads. |
| Cost per signed job | Known by channel | Tells you where to invest. |
| Quality feedback | Weekly | Closes the loop with marketing. |
The rule is simple: don't increase the budget until the current system converts better. Otherwise you just accelerate the leak.
