Allstate Roof Estimates: Missing Line Items and How to Recover Them

An Allstate roof claim usually moves fast at the front end. The adjuster inspects, the claim summary lands in the portal or the inbox, and it has a number on it. Then you read the scope behind that number, and contractors report it comes up short. Not by a rounding error, by the exact items that decide whether the job pays or breaks even.

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.

Here is the working pattern for an Allstate roofing claim: what the claim summary is actually telling you, the line items that most often miss the page, the code and manufacturer citations behind each one, and how to package it so a desk reviewer can approve it in one pass.

First, Read the Claim Summary Correctly

On a replacement cost policy, and most homeowner policies are written that way, the summary splits one job into two numbers. Read them in this order.

• Replacement cost value (RCV). What it costs to rebuild the roof at today's prices, before depreciation is taken out.
• Depreciation and actual cash value (ACV). The carrier holds back the value of the roof's age and condition, and pays the ACV now.
• Deductible. Yours, and it comes off the top.
• The line most people skip. The summary also prints what the claim pays if the withheld depreciation is recovered, usually labeled something close to "net claim if depreciation is recovered." That second number is the whole point of the next conversation.

Seen in that order, the document stops being confusing. The scope is what the carrier has agreed to build. Depreciation on those lines is held back until the work is done and invoiced, which is why the final check lands bigger than the first one. And anything the scope left out is not held back at all, it was never on the page to begin with.

That is the entire game. The scope behind the summary is a list, and a list can be added to with evidence.

Why the First Number Comes In Short

Three things happen in the first pass, and all three are predictable.

• The template decides the list. Estimators work from a standard roster of items for the loss type in front of them. Anything outside that roster gets written only when someone adds it deliberately, which is why the same items go missing across an entire region, claim after claim.
• Measurements get rounded on the way in. Many initial scopes start from imagery and a fast measurement service, and those numbers get rounded before they land in the estimate. A 29.7-square roof becomes 29 squares, and a full square of shingles plus the labor to install it is gone before anyone climbs a ladder.
• The first pass is written to close. A scope that settles a simple claim is not the same document as one that pays for a full replacement. Your documentation is what 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 lines that most often come up missing on a roof scope, roughly in the order they cost you money. Every one of them stands on a code section, a manufacturer instruction, or plain arithmetic.

1. Ice and water shield, at the eave and beyond it

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 below, an ice barrier is required, and it runs from the roof edge to at least 24 inches inside the exterior wall line. That is IRC R905.2.7.1 in the 2018 editions many states still use, and IRC R905.1.2 in the 2021 editions.

Two things go wrong on scopes. The barrier gets left off a re-roof that requires it. Or it gets written for the eave and nothing else, no valleys, no penetrations, when the shingle manufacturer's own installation instructions call for it in both places. The manufacturer instruction is the stronger argument, because the carrier is paying to install that product the way the instructions require.

2. Drip edge, on the eaves and the rakes

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: 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 usual 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 counterflashing

Every penetration and every wall intersection is its own piece of metal, and each belongs on the estimate as its own line. Step flashing and counterflashing at walls and chimneys is flashing the code requires (IRC R905.2.8.3). If the flashing was already there, and on a re-roof, it was, it comes off and goes back on in kind. It does not get absorbed into the labor on the field shingles.

Photograph every pipe boot, wall step, and chimney counterflashing before the tear-off. Ten photos taken at the right moment save a week of back-and-forth, because the reviewer's next question is always the same one: 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 to 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, documented while the deck is open

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 documentation request instead.

7. Gutters: detach and reset

You cannot install drip edge and starter with the 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.

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.

The Depreciation Conversation, and Why It Is Not a Fight

On a replacement cost policy, depreciation is withheld on the first payment and released on the second. That is the design of the policy, not a carrier trick, and it is worth saying out loud to a homeowner who is staring at two different numbers on the same page.

Three things decide how that second payment goes.

• Recoverable vs. non-recoverable. Depreciation on items you actually replaced is recoverable, usually at the rate the carrier already applied. Depreciation on work that was never done is not. Match your invoice to the scope lines you completed.
• The trigger is documentation, not time. The second payment typically requires a completion request with your invoice. Nobody is watching the calendar on your behalf.
• Scope changes are normal. When decking turns out worse than the ground suggested, or the tear-off uncovers something the first pass could not see, the corrected line belongs in the same supplement. A change order with a photo is the most ordinary document in this business.

Here is the part that surprises contractors new to replacement cost claims: a supplement after the first payment is not an accusation and not a renegotiation. It is the schedule for the parts of the job nobody could price until the roof was open.

How to Build the Supplement

1. Put the scope and your estimate on the same structure. Line by line, same rooms, same quantities, same order. A comparison you can read in two minutes beats a narrative an adjuster has to decode.
2. Sort the gap by what backs it. Code items cite a section. Manufacturer items cite the installation instructions. Measurement items cite your numbers. Photograph items carry photos. Keep the four categories separate, they get reviewed by different logic.
3. Quote the rule, not your opinion. One sentence per line: what the item is, what requires it, what it costs. No adjectives. A reviewer can say yes to a citation; there is no column on the form for emphasis.
4. Attach the evidence in the order it is cited. Photos numbered to match the line notes. If a reviewer has to hunt, the supplement slows down.
5. Send one supplement, not five. Batch every documented item into a single submission with a cover note that says what is inside and what each item rests on. Five partial supplements invite five partial answers.
6. Keep the trail. Note the date submitted, who reviewed it, what was approved, and what came back denied. Denials are a list too, and a denied line with a citation behind it is the beginning of an appeal, not the end of the job.

Where the Software Fits

A carrier scope PDF is easy to read and slow to work with. The items are there as text, but they are not in an estimate you can edit, compare, or price, so the comparison happens by hand, on paper, and the math gets done twice.

Converting the scope PDF into an .esx file puts the carrier's own line items, quantities, and prices into a Xactimate estimate you can open next to your own. From there the comparison is mechanical: same structure, line against line, and the difference is a list you can turn into a supplement instead of a stack of paper you have to translate. A scope converts in about two minutes, and the Completeness Advisor checks the result against 93 rules covering construction, code, and supplemental items, each suggestion cited, and nothing added to the estimate without you putting it there.

That is the whole point. The carrier wrote a list. You are allowed to answer with a better-documented one.
