Key Takeaways
Complete guide to the roofing supplement process, from discovering hidden damage during tear-off to getting insurance approval. Written for contractors.
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.
Crew discovers hidden damage
During tear-off, concealed conditions are exposed: rotted decking, corroded flashing, missing ice & water shield.
Document at the point of discovery
Photograph each finding with context and detail shots. Tag the damage type, roof area, and add field notes.
Generate the supplement report
AI writes a professional narrative. Xactimate line codes and pricing are mapped automatically.
Email to the adjuster same day
Send a branded PDF report directly to the insurance adjuster before the crew leaves the job site.
Adjuster reviews and approves
Clear documentation with photos, narratives, and correct codes leads to faster approvals.
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.
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:
Fresh documentation is more credible. A supplement submitted the same day as the tear-off carries more weight than one submitted three weeks later.
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.
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. Xactimate CSV export with correct line codes and pricing.
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.
