State Farm agreed the roof is a total loss. The estimate landed the same day. And the number on it is short — not by a little, by the exact items that turn a roofing job into a break-even favor.
None of that is unusual, and none of it is final. A carrier's first estimate is an opening position, written fast from a template. The supplement is where the rest of the job gets documented — and the contractors who get paid cleanly check the same handful of items on every file.
This is the pattern on State Farm roofing claims: where scopes come up short, the code sections that back each missing line, and how to package a supplement a desk reviewer can approve in one pass.
Why a State Farm Scope Comes Up Short
Large carriers write residential property estimates on Xactimate, and State Farm is no exception. The adjuster's job is to measure the damage and apply a template. Three things in that process create the gaps you find later.
- The template decides the list. Adjusters work from a standard roster of line items for the loss type in front of them. Anything outside that roster gets written only when the adjuster adds it deliberately — which is why the same items miss the same files across a whole region.
- Measurement is faster than a ladder. Many initial scopes start from imagery and a quick measurement service, and those numbers get rounded on the way into the estimate. Contractors report watching a 29.7-square roof get written as 29 squares — a full square of shingles and the labor to install it, gone before anyone climbed the roof.
- The first pass is written to be closed. A scope that settles an easy claim is not the same document as one that pays for a full replacement. Your documentation moves it from one to the other.
Read that list from the contractor's side and it stops being a complaint. It becomes a checklist.
The Items That Miss the Page Most Often
These are the line items that go missing on State Farm roof scopes most often, roughly in the order they cost you money. Every one has a code section, a manufacturer instruction, or plain arithmetic behind it.
1. Ice and water shield at the eaves — and everywhere else it belongs
The ice barrier is the most common code-required miss in cold-weather markets. The rule keys on climate: where the average January daily mean temperature is 25 degrees or colder, an ice barrier is required, and it has to run from the roof edge to at least 24 inches inside the exterior wall line. That is IRC R905.2.7.1 in the 2018 code editions many states still use, and IRC R905.1.2 in the 2021 editions.
Two things go wrong on scopes. First, the barrier gets left off the estimate entirely on a re-roof that requires it. Second, it gets written for the eave and nothing else — no valleys, no penetrations — when the shingle manufacturer's own installation instructions call for it there. Manufacturer instructions are the stronger argument, because the carrier is paying to install that product the way the instructions require.
2. Drip edge
Drip edge metal is cheap per foot, and that is exactly why it gets treated as a rounding error — until you look at the quantities. The code is unambiguous: a drip edge is required at the eaves and the rake edges of shingle roofs, and adjacent pieces have to overlap by at least 2 inches (IRC R905.2.8.5).
The common miss is a scope that pays the eaves and skips the rakes, or the reverse. Measure both and write both. On a 40-foot gable, those rakes are metal, fasteners, and labor you already bought.
3. Starter course
Shingle manufacturers require a starter course at the eaves and along the rakes, and it is a separate line from the field shingles. On a fast scope it dissolves into the field quantity — which means you buy it, haul it, and install it for free.
4. Pipe boots, step flashing, and chimney flashing
Every penetration and every wall intersection is its own piece of metal, and each belongs on the estimate as its own line. If the flashing was already there — and on a re-roof, it was — it gets removed and replaced in kind, not absorbed into the labor of the field shingles.
Photograph every pipe boot, wall step, and chimney counterflashing before the tear-off. Ten photos at the right moment save a week of back-and-forth, because the reviewer's next question is always the same: show me what was there.
5. Ridge cap and ventilation, by measurement
Ridge cap is written by the linear foot. Ridge and intake ventilation are written by the quantity the roof actually needs. A scope that guesses at the ridge length rather than measuring it comes up short in two places at once, because the cap and the vent hinge on the same number.
Walk the ridge with a tape, count the intake openings, and write what you measured. Ventilation is a code item and a manufacturer item, not a preference — the installation instructions for the shingles you are installing specify the ratios the roof has to hit.
6. Decking
Nobody can price decking from the ground, and nobody should pay for it from the ground either. Decking is documented at tear-off: which sheathing was damaged, how many sheets were replaced, photographed and counted while the deck is still open. A decking line with photos behind it moves; one built on a guess gets a request for documentation instead.
7. Gutters: detach and reset
You cannot install drip edge and starter with gutters hanging in the way. Shingle manufacturers' installation instructions call for the gutters to come off and go back on, and re-hanging them after the re-roof is where the slope and the seal get corrected. It is a real line item on every re-roof, and it gets skipped on most of them.
8. Debris, hauling, and the trades you sub out
Debris removal is paid at the method the job used: a dumpster count that matches the layer count and the access, not a flat guess that assumes a clean driveway and one layer. And when you sub out gutters, electrical, or HVAC work, those trades belong on the estimate as their own items with the invoices behind them — not folded into a general line where nobody can see them.
Key Insight: Most State Farm scope misses are not judgment calls. They are items the code requires, the manufacturer requires, or the roof's own measurements require. That is exactly why they get paid: the argument is not "I want more money," it is "here is the rule, here is the photo, here is the measurement." A desk can approve documentation; it has no mechanism to approve a feeling.
Where the Quiet Numbers Cost the Most
Missing line items are easy to spot, because the line is absent. Underpaid quantities are harder, because the line is right there and looks fine. Two places to check on every claim:
- Roof area. Run the ridge, the eaves, and the valleys yourself, or order a measurement you trust. If the scope lands below your number, document the difference before the tear-off, not after. Rounded-down measurement is one of the most-reported patterns on carrier scopes in storm markets, and the correction for it is arithmetic — not argument.
- Steep and cut-up geometry. Pitch and complexity change both the material and the labor. If the roof is steep enough that you are staging harnesses and roof jacks, the estimate should show it. Walk the pitch and write what it requires.
The rounding question cuts deepest on replacements, because the shingle quantity, the felt, the ice barrier, the drip edge, and the ridge cap all move together with the same square count. One square short in the measurement is short on six lines at once — and every one of those lines is a line you already paid for at the supply house.
What Roof Claims Are Worth in 2026
Two things are happening at once in this market: fewer claims get filed, and the ones that do are more expensive. That is why documentation quality matters more this year than it did in 2023.

| Average residential roof replacement cost (2025) | $17,631 | Verisk 2026 U.S. Roof Report (May 29, 2026) |

| Ice barrier: trigger and required coverage | Average January daily mean temperature of 25 F or below; barrier runs from the roof edge to 24 inches inside the exterior wall line | IRC R905.2.7.1 (2018 editions); IRC R905.1.2 (2021 editions) |
| Drip edge: required locations and overlap | Eaves and rake edges of shingle roofs; minimum 2-inch overlap between adjacent pieces | IRC R905.2.8.5 |
Read the table from the contractor's side. Claim volume is down, severity is up, and roof condition is doing work that hail used to do. A desk that receives fewer files has more time to read the ones it gets, and that cuts both ways. A padded supplement gets slowed down or denied. A documented supplement moves, because everything the reviewer needs is already attached.
How to Build the Supplement
- Get the carrier's scope onto the same structure. Import or rebuild the State Farm scope so both estimates use the same categories, line items, and units. Two documents built the same way is a conversation. A PDF against a hand-typed list is an argument.
- Submit one supplement, not five. Group the items, attach the documentation, send it once. Piecemeal submissions get read as piecemeal requests.
- Cite something on every new line. A code section, a manufacturer instruction, or a measurement with photos behind it. Notes on the line item do the same work in Xactimate that a cover letter does on paper: they explain the why to the person who decides.
- Photograph before the roof is gone. Decking, flashing, ice barrier, vents, and anything you are going to bill for. The tear-off is the only time those photos exist.
- Match the price list instead of arguing with it. The receiving machine's price list does the pricing on import, so if the list edition differs, totals move. Check the list your copy of Xactimate has loaded and expect the file to reprice to it.
The Ten-Minute Scope Check
Before you decide a scope is close enough, run the same list on every claim:
- Ice barrier at the eaves to the required width, plus valleys and penetrations per manufacturer instructions
- Drip edge at the eaves and the rakes
- Starter course, written separately from the field shingles
- Every pipe boot, step flashing, and counterflashing as its own line
- Ridge cap and ventilation measured, not guessed
- Decking documented at tear-off, by sheet
- Gutters detached and reset
- Debris method that matches the layers and the access
- Roof area and pitch matching what you measured on site
Where ESXPress Fits
Every step above runs on one task: getting the carrier's scope into Xactimate as a working file so the comparison is honest. ESXPress converts a carrier scope PDF into a Xactimate-ready .esx file, keeping the line items, categories, and notes in the same structure the adjuster used. A typical scope converts in about two minutes, up to 1,000 line items. You review every line, price, and total before anything is submitted — that review is the job, not a formality.
Frequently Asked Questions
What does State Farm leave off a roof estimate most often?
The same handful of items shows up missing again and again: ice and water shield at the eaves, drip edge on the rakes, the starter course, individual flashing pieces like pipe boots and step flashing, ridge cap and ventilation quantities, decking, and gutter detach and reset. Most of them are code items, manufacturer items, or measurement items — which is exactly why they are recoverable.
Is ice and water shield required on my roof?
In most cold-weather markets, yes. The rule keys on climate: where the average January daily mean temperature is 25 degrees or below, an ice barrier is required from the roof edge to at least 24 inches inside the exterior wall line — IRC R905.2.7.1 in the 2018 editions, IRC R905.1.2 in the 2021 editions. Shingle manufacturers' installation instructions often extend it to valleys and penetrations, and that is the stronger argument on a supplement anyway.
Does drip edge have to go on the rakes too?
Yes. The code requires drip edge at the eaves and the rake edges of shingle roofs, with adjacent pieces overlapped by at least 2 inches (IRC R905.2.8.5). Paying the eaves and skipping the rakes is one of the most common quantity misses on a roof scope.
Can I be paid for code-required items that were not in the first estimate?
Yes. Code-required items are ordinary supplement items when your jurisdiction has adopted the code you are citing. Documentation is what carries them: cite the section, show the measurement or the photo, and let the line stand on the rule instead of on preference.
What is the fastest way to compare a State Farm estimate against mine?
Get both onto the same structure. Convert the carrier's scope PDF into a Xactimate .esx file, open it in your copy of Xactimate, and compare line by line against the price list you have loaded. A scope converts in about two minutes, and the comparison is apples to apples.
Bottom Line
A State Farm roof estimate is a starting point, not a verdict. It gets written fast, from a template, off a measurement that may have been rounded — and the items it misses are almost always the same ones. Check the list, document each line, and send one clean supplement with the code and the photos attached. That is how the number on the page catches up to the roof on the house.
