How to Price a Commercial Roof Coating Job Without Losing Margin

Ask ten commercial coatings contractors how they price a job and most will describe some version of a flat per-square-foot number they've used for years. That number might have been right once. It's rarely right on every job, and it's almost never protecting the margin it was originally set up to protect.

The Real Pricing Inputs

A commercial roof coating job's price should come from five inputs, not one:

• Square footage. The starting point, but not the whole picture.
• Substrate condition and prep required. Power washing, patching, and priming time varies enormously between a well-maintained roof and one that's been deferred for years — and prep time is where bids most often underestimate labor.
• Coating system and mil thickness. Material cost and application time both scale with the system specified, and substituting a cheaper system to win a bid usually means eating warranty risk you didn't price for.
• Access and staging. Roof height, equipment access, and site logistics change labor time in ways a flat rate never captures.
• A built-in margin target. Not a margin you hope is left over after the job — a number built into the bid from the start.

Why Estimating Software Doesn't Fix This

Estimating software will calculate whatever number you feed it. If your prep-time assumptions are off, or your margin target isn't actually programmed into the formula, the software just produces a wrong number faster. The tool isn't the problem — the system feeding it is.

Building a Repeatable System

The fix isn't a better spreadsheet. It's a documented process:

1. Track actual job costs after every project, not just at bid time — this is what turns next year's estimates from guesses into data.

2. Separate prep time from application time in your cost tracking, since these two categories behave very differently across job conditions.

3. Set the margin target before you build the bid, not after — if the number doesn't work with a real margin built in, the bid needs to change, not the margin.

4. Review recent wins and losses together, not just wins — a job you lost on price sometimes reveals a scope-communication problem, not a pricing problem.

Where This Actually Gets Fixed

Most contractors don't have a bad pricing formula — they have an undocumented one that lives in someone's head and drifts over time. Estimating & Bidding Systems coaching is built specifically to turn that into a documented, repeatable process your whole team can use, not just the owner.
