What happens when your crew finds hidden damage

It happens on almost every tear-off. Your crew pulls back the shingles and discovers something the adjuster didn't, and couldn't, see during the initial inspection. Rotted decking along the eave. Corroded step flashing at the chimney. Missing ice and water shield in the valley. A pipe boot that crumbled when they pulled the old shingles off.

This concealed damage is legitimate additional work that the insurance policy should cover. The process for getting it covered is called a supplement, and it starts the moment your crew discovers the damage.

1

Crew discovers hidden damage

During tear-off, concealed conditions are exposed: rotted decking, corroded flashing, missing ice & water shield.

2

Document at the point of discovery

Photograph each finding with context and detail shots. Tag the damage type, roof area, and add field notes.

3

Generate the supplement report

AI writes a professional narrative. Xactimate line codes and pricing are mapped automatically.

4

Email to the adjuster same day

Send a branded PDF report directly to the insurance adjuster before the crew leaves the job site.

5

Adjuster reviews and approves

Clear documentation with photos, narratives, and correct codes leads to faster approvals.

No email or sign-up needed. General guidance, not legal advice. Adjust it to your carrier's, client's and state's requirements.

Phase 1: Discovery and documentation

The most critical phase happens on the roof. When damage is discovered during tear-off, it needs to be documented immediately, before new materials cover it up.

Effective documentation includes: • Multiple photographs per finding (wide context shot + close-up detail) • Identification of damage type (decking, flashing, ice & water, pipe boot, drip edge) • Location on the roof (front slope, back slope, valley, chimney, eave, ridge) • Estimated quantity (number of sheets, linear feet, square footage) • Field notes describing the condition

The biggest mistake contractors make is waiting until they get back to the office to document findings. By then, photos are buried in camera rolls, details are fuzzy, and the urgency is gone.

Capture this on the roof, not from memory.

Supplement Snap lets your crew take photos and voice notes at tear-off and drafts a report you review before sending. Your first project is free.

Phase 2: Writing the supplement

The supplement is a formal request to the insurance carrier for additional payment. It includes:

A narrative explaining what was found, where, and why it wasn't visible before tear-off

Xactimate line items with the appropriate codes, quantities, and pricing

Supporting photographs

Reference to applicable building codes (when relevant)

The narrative is the heart of the supplement. It needs to clearly communicate that the damage was concealed, was discovered during tear-off operations, and requires additional work beyond the original scope to restore the roof system properly.

Many contractors either skip the narrative entirely (just submitting Xactimate line items) or write something so vague that the adjuster can't justify approval. The narrative should be specific, professional, and reference your photographic evidence.

Phase 3: Submission to the insurance carrier

Submit the supplement to the insurance adjuster as quickly as possible, ideally the same day the damage is found. Speed matters for two reasons:

1

Fresh documentation is more credible. A supplement submitted the same day as the tear-off carries more weight than one submitted three weeks later.

2

The adjuster may want to re-inspect. If you've already installed new materials over the damage, a re-inspection is impossible.

The best submission format is a professional PDF report with an attached Xactimate-compatible spreadsheet. Email it directly to the adjuster with the claim number in the subject line.

Phase 4: Adjuster review and negotiation

After submission, the adjuster reviews your supplement. This can take 3–14 business days depending on the carrier. Possible outcomes:

Approved in full: the carrier agrees with your findings and adjusts the claim

Partially approved: some items approved, others denied or reduced

Re-inspection requested: the adjuster wants to see the damage in person

Denied: the carrier rejects the supplement (see our guide on what to do when this happens)

If partially approved, review which items were denied and why. You can resubmit with additional documentation or escalate to a supervisor. If a re-inspection is requested, coordinate with the adjuster and be prepared to show the documented evidence.

Who does what in the supplement process

A smooth supplement depends on clear handoffs between the people involved.

The crew: Finds and photographs damage during tear-off, with labels and notes.

The project manager or estimator: Measures, writes the narrative and builds the line items.

The office: Assembles the package, sends it and tracks the response.

The adjuster: Reviews the package, may visit and decides what is approved.

The homeowner: Stays informed and may need to sign documents.

Most delays come from a handoff that fails, usually photos that never reach the office or notes that no one recorded. Fixing that handoff is often the biggest improvement a roofing company can make.

What a realistic timeline looks like

Timelines vary by carrier, claim volume and the size of the supplement, so use the steps below as a rough order of events and not a promise. What you control is the first half: documenting and sending quickly.

The longer you wait to send, the harder verification becomes, and the more the job moves on without you. The sooner the package reaches the adjuster, the sooner questions can be answered while the damage is still visible.

Day 1

Tear-off and discovery

Hidden damage is found, photographed and measured before it is covered.

Same day

Write and send

The narrative, line items and photos go to the adjuster with a clear summary.

Following days

Carrier review

The adjuster verifies the package and may ask questions or request a visit.

After review

Approval or negotiation

Approved items are paid. Disputed items get a written response with evidence.

What to have ready before you call the adjuster

A short phone call goes much better when you are prepared. Have these in front of you:

The claim number and policy holder name

The date of loss and the date of tear-off

A one-page list of findings with photo numbers

Measurements and quantities for each item

Any code references you rely on

The email address the carrier wants documents sent to

After the call, send a short email summarizing what was agreed. That record protects you if details are disputed later.

Where time gets lost, and how to get it back

Four steps eat most of the time:

1

Photos stuck on phones: Fix this by uploading from the roof, not at the end of the day.

2

Writing from memory: Fix this by capturing a short note with every photo.

3

Formatting: Fix this with a consistent template for narratives and reports. See our <a href='/blog/roofing-supplement-template'>supplement template</a>.

4

Chasing the carrier: Fix this with dated written follow-ups.

If you improve only one thing, make it the first: getting labeled photos off the roof and to the office the same day.

How Supplement Snap streamlines the entire process

Supplement Snap was designed around this exact workflow:

Phase 1 (Discovery): Your crew captures photos, tags damage type and roof area, adds voice notes, all from the roof during tear-off

Phase 2 (Writing): AI generates professional supplement narratives from the field data. An Xactimate-style CSV gives you a starting list of suggested line codes and approximate prices to review and price yourself.

Phase 3 (Submission): One-click PDF report generation and email to the adjuster, same day, from the field

Phase 4 (Tracking): Claim pipeline tracks each project from In Progress through Submitted to Approved

The entire process that used to take days of office work now happens in minutes, right from the job site.

Frequently asked questions

How long does the roofing supplement process take?

It varies by carrier and claim. The part you control is how fast you document and submit, so do both on the day damage is found.

When should a supplement be submitted?

As soon as the hidden damage is documented, ideally the same day and before new materials cover the area.

Who submits the supplement, the contractor or the homeowner?

Usually the contractor, since they have the photos, measurements and technical detail.

What happens if the adjuster wants to inspect the roof again?

Offer specific times, keep the damage visible if possible and bring a one-page summary of the disputed items.
