This supplement narrative example is built for insurance restoration: baseline vs delta, line-item evidence, and faster approvals.
Most supplements get delayed for one reason: they read like opinions instead of deltas. A strong supplement narrative is not a story. It’s a controlled change against a baseline, with evidence attached to each disputed line.
This post gives you:
- a reviewer-ready supplement packet structure
- an evidence checklist (what to attach so it doesn’t get kicked back)
- a photo ID system you can use today
- a copy/paste supplement narrative template
- worked examples you can adapt in minutes

Who this is for
Best for: restoration contractors, mitigators, estimators, adjusters, PMs submitting supplements
Use when: baseline scope/price is missing required work, concealed damage is discovered, or code/assembly requirements apply
The supplement rule: baseline vs delta
Your supplement should always reference:
- the baseline (carrier estimate, Xactimate line list, desk adjuster scope, prior approval)
- the delta (what must be added/removed/modified)
- the evidence (why it’s required)
If you can’t point to baseline + delta + evidence, expect delay.
Reviewer-ready supplement packet (1 page structure)
A clean supplement pack includes:
- Cover summary (baseline reference + delta overview)
- Delta table (Add/Modify/Remove + quantity + room)
- Evidence index (photo IDs + what they show)
- Line-item narratives (one block per item)
- Total cost impact summary (optional)
This makes it easy for a reviewer to approve without hunting.
Photo ID system (stops “where is that shown?” kickbacks)
Use a simple convention and reference these IDs in each line item:
Pre-demo/context:
- P01, P02, P03…
Demo/open/concealed:
- D01, D02, D03…
Measurements/moisture:
- M01, M02, M03…
Example:
- “Evidence attached: D02 (wet insulation exposed), M01 (moisture reading), P03 (staining at baseboard line)”
Evidence checklist (attach the minimum that proves each line)
Attach evidence that matches the reason category.
Concealed damage:
- P-series context photo(s)
- D-series exposed condition photo(s)
- M-series measurement/moisture photo(s)
Code/inspection requirement:
- inspector note or AHJ requirement (if available)
- photo showing condition triggering requirement
- short statement: “VERIFY with AHJ; applies if scope includes ___”
Assembly/system requirement (manufacturer/standard repair, not “opinion”):
- 1–2 screenshots of manufacturer instructions (max)
- photo showing assembly conditions (flashing, underlayment, shower pan, etc.)
- scope boundary (what area is affected)
Material availability:
- discontinued notice / lead time confirmation
- owner selection approval if alternate is chosen
Waste/disposal:
- disposal tickets or load notes (if applicable)
- photos showing tear-out area/volume
Labor/access constraint:
- access constraint photos (tight space, height, containment)
- setup photos (containment/negative air) if relevant to scope
Tip: Don’t attach everything. Attach the minimum evidence that proves each requested line.
Delta overview table (simple format)
Add:
- [Item] | Qty | Room | Reason | Evidence IDs
Modify:
- [Item] | Old qty → New qty | Room | Reason | Evidence IDs
Remove:
- [Item] | Qty | Room | Reason | Evidence IDs
Even a simple version of this improves approval speed.
Supplement narrative example (copy/paste template)
Project:
- Insured:
- Loss date:
- Claim number:
- Location:
- Carrier / TPA:
- Baseline reference (estimate date/version):
- Prepared by:
- Date:
Cover summary (2–4 lines):
This supplement documents required scope deltas not included or under-scoped in the baseline estimate, based on verified field conditions and supporting evidence attached. Requested items are presented as Add/Remove/Modify with quantities, locations, and evidence IDs.
Delta overview:
- Add:
- Remove:
- Modify:
Evidence index (list photo IDs briefly):
- P01:
- D01:
- M01:
Line-item narrative block (repeat per item):
Item:
Baseline status:
- Not included / Under-scoped / Incorrect quantity / Incorrect method
Requested delta:
- Add / Remove / Modify
- Quantity:
- Location/room:
- Reason category: concealed damage / code/inspection / assembly requirement / access constraint / availability
Evidence attached:
- Photo IDs:
- Measurements/moisture:
- Notes/report:
- Inspector/AHJ note (if any):
- Manufacturer reference (if any):
Narrative (3–6 sentences, factual):
State what was found, where, how it was verified, why it’s required to restore/repair the assembly, and what work is requested. Avoid blame. Avoid “should be covered.” Keep it measurable.
Cost/schedule impact (optional):
- Estimated cost impact:
- Schedule impact:
Close:
We request approval for the above delta items to restore the property to pre-loss condition based on verified field conditions and supporting documentation provided. Please advise if additional documentation is required.
Narrative rules (keep it approval-focused)
Do:
- location-specific language
- measurable quantities
- evidence IDs in every item
- short, factual blocks
Don’t:
- blame or emotion
- long paragraphs
- “should be covered”
- vague statements without evidence
Worked examples (use these patterns)
Example 1: concealed damage (wet insulation)
Baseline reference:
- Carrier estimate dated [date], includes drywall patch but excludes insulation replacement
Item:
- Remove and replace wet insulation at exterior wall cavity
Baseline status:
- Not included
Requested delta:
- Add
- Quantity: __ sq ft
- Location: guest bedroom exterior wall
- Reason: concealed damage verified after removal
Evidence attached:
- P03 (staining at baseboard line)
- D02 (wet insulation exposed)
- M01 (moisture reading at location)
Narrative:
After removal of baseboard at the guest bedroom exterior wall, wet insulation was observed within the wall cavity. Moisture readings remained elevated and insulation was visibly compromised. Insulation replacement is required to restore the wall assembly and prevent trapped moisture prior to closing. Supporting photos and readings are attached.
Example 2: code/inspection requirement (GFCI/AFCI or smoke/CO)
Baseline reference:
- Baseline scope includes electrical reconnect but does not include protection upgrade requirements
Item:
- Electrical protection upgrades as required for modified circuit
Baseline status:
- Not included / under-scoped
Requested delta:
- Add (or Modify if a line exists)
- Quantity: __ (per outlet/circuit)
- Location: kitchen / bath / bedroom (as applicable)
- Reason: code/inspection requirement (jurisdiction-specific)
Evidence attached:
- P01 (work area context)
- D01 (existing outlet/circuit location)
- Inspector/AHJ note if available (or mark VERIFY with AHJ)
Narrative:
Scope includes modification to the existing electrical connection in the [location]. Electrical protection requirements may apply when circuits/outlets are modified. This item requests allowance to perform required protection upgrades as directed by inspection/AHJ for compliance at time of final. Verification will be confirmed with AHJ/inspection requirements for the scope.
Example 3: material availability (discontinued flooring/tile)
Baseline reference:
- Baseline includes like-for-like flooring replacement
Item:
- Flooring material substitution due to discontinued product
Baseline status:
- Under-scoped (baseline assumes availability)
Requested delta:
- Modify
- Old: baseline flooring selection
- New: approved equivalent selection (or closest match)
- Reason: availability/discontinued
Evidence attached:
- Manufacturer discontinued notice or supplier confirmation
- Owner selection approval (if needed)
Narrative:
Baseline scope assumes matching material availability for like-for-like replacement. Supplier/manufacturer confirmation indicates the specified material is discontinued or unavailable within required lead time. This item requests approval to substitute an equivalent material to complete restoration within schedule constraints. Supporting availability documentation and selected alternate are attached.
What makes supplements get approved faster
- baseline reference is explicit
- every request is Add/Remove/Modify
- each item has evidence IDs
- narrative is factual, short, and location-specific
- quantities are measurable (not “as needed”)
- a simple delta table and evidence index are included
Common supplement mistakes (avoid these)
- narrative with no baseline reference
- “required” without evidence
- mixing multiple requests into one paragraph
- no quantities or locations
- blaming the carrier instead of documenting conditions
