The Carrier's Estimate Is Written in Software — Learn to Read It

The problem in one breath

The adjuster hands you a printout: page after page of coded lines, abbreviations and unit prices, with a total at the bottom. You look at the total, decide it's low, and start arguing about the roof. He answers in line items. Two men, two languages, and the one who can't speak the document loses the money.

Why it happens

Storm estimates aren't written by hand, they're generated in estimating software, and on residential claims the name you'll run into most is Xactimate. What comes out is a list of priced tasks, not a price for a roof. Nobody in this trade gets taught to read one — you learn shingles, not paperwork. So an owner who can measure a roof in his sleep goes into the one conversation that decides what he gets paid without being able to point at a single line and say what's wrong with it. Meanwhile every supplement you'll ever file (M6-08) is a change to that document.

The play

1. Read it as a list, not as a total. Every line is one task with four things attached: what it is, how much of it, what unit it's counted in, and the price for that unit. The total is just those lines added up. Stop reacting to the bottom of the last page.

2. Learn the units, because your takeoff already speaks them. Read the unit column on his lines before you compare anything: roofing gets counted by the square, by the foot, by the square foot or one at a time, and the short codes for those sit right in that column. Squares and feet are what you measured on the takeoff sheet (M10-01); the counts — boots, vents, skylights, chimneys — are on the measure card you filled out in the driveway. That's the bridge: you don't have to argue about roofing, you can set his quantities beside yours in the same units.

3. Check quantities before you ever mention price. Squares, feet of ridge, feet of valley, feet of drip edge, number of pipe boots, layers of tear-off. A quantity that's simply too small is the easiest thing in the world to fix, because it's arithmetic, not opinion — and it's the most common thing wrong. Mark every line where his number and your number don't match.

4. Then look for lines that aren't there at all. Work the roof actually takes that the document never lists. Name the missing item the way the document names things, attach your measurement and a photo, and ask for it to be added. A supplement is a paperwork job, not an argument.

5. Ask, in writing, for the whole document. Ask for the full estimate rather than a summary page, and ask which price list and date it was written on. What a given carrier will share, what their price list carries and how their software is set up is theirs to answer — so ask them plainly rather than assuming, and put the question in the same email as your measurements.

6. Never bluff the software. You don't need to know the program better than the adjuster does. You need your own measurements, in his units, next to his lines. Questions with numbers attached move estimates. Opinions don't.

Do this this week

Pull one open storm job. This is not the missing-items pass you ran in M6-08 — this one is quantities only. Put the carrier's estimate next to your takeoff sheet and go down it marking every number that doesn't match yours. Send that list with your measurements attached. It's the easiest money in the file and you can do it tonight at the kitchen table.

The tool

No spreadsheet — the gaps you find go straight onto the supplement worksheet in M6-08, which already tracks what was allowed, what the roof needs, and what's still open. This card is what you read the document with:

  READING THE CARRIER'S ESTIMATE — quantities first, price last

  BEFORE YOU OPEN IT      have your own takeoff for that roof in the other hand

  EVERY LINE HAS          what it is | how much | the unit | the unit price
  THE UNIT COLUMN         squares · linear feet · square feet · each — read it first

  PASS 1 — QUANTITIES (arithmetic, not opinion)
  [ ] squares      [ ] ridge LF     [ ] valley LF    [ ] drip edge LF
  [ ] starter LF   [ ] tear-off layers               [ ] pipe boots / vents EA

  PASS 2 — LINES THAT AREN'T THERE
  [ ] ice-and-water where it belongs   [ ] flashing / step flashing
  [ ] steep or 2-story                 [ ] disposal for every layer
  [ ] anything code or the permit office requires here

  ASK IN WRITING          full estimate, not the summary  ·  which price list and date

  Send quantities first, with your measurements attached. Argue prices never; ask questions always.

If your crew is 1099

Nothing to adjust — this is office work between you and the carrier, and no crew is involved either way. Just don't let a sub's verbal count of the roof become the number you send an adjuster: send the takeoff you measured and can stand behind.

One more thing: this play is how we run a shop — it's not legal advice. Rules change by state and by contract, so before you act on the legal-sounding parts, run them past your own attorney or accountant. It's your business, and what you do with any of this is your call and your responsibility.
