THE TRUE COST OF MANUAL ESTIMATING
A line-by-line accounting of what manual estimating costs an $8M roofer — including the costs nobody puts on the invoice.
When an operator decides whether to invest in estimating automation, the framing is usually "do I want to pay $X/year for a tool." The framing is wrong. The right framing is "do I want to keep paying $Y/year for manual estimating, where most of $Y is invisible on the invoice."
This is a line-by-line accounting of what manual estimating actually costs an $8M roofer. Operators run different shops, so the numbers below are typical-case from our customer base, not universal. Adjust to your operation.
Visible costs
**Estimator labor.** At $8M revenue, most operators staff 2–4 estimators. Loaded cost (salary + benefits + truck + admin overhead): typically $75K–$110K each. Three estimators: $225K–$330K annually.
**Tape, ladder, drone, software licenses.** Equipment, mileage, tape-and-ladder for hand measurement, occasional drone capture, and basic software licenses: $15K–$30K annually across the team.
Visible total: $240K–$360K annually for the estimating function on an $8M operator.
Invisible costs
Now the invisible portion, which is typically larger than the visible portion.
Cost 1: Under-bidding from measurement error
Hand-built estimates under-bid by a median 6.2% (see our audit of 1,000 estimates). On $8M revenue with a typical 30% gross margin, that's roughly $148K of gross margin not captured annually because measurements rounded down.
Cost 2: Lost deals from slow turnaround
Time-to-quote correlates strongly with close rate (detailed in first-to-the-roof). An operator delivering quotes in 24 hours loses meaningfully more deals than one delivering in 90 minutes. Conservatively, 8–12% of inbound leads are lost specifically to slow turnaround.
