The Roofing Supplement Playbook: How Contractors Recover What Adjusters Miss

On a storm restoration job, the insurance adjuster writes a scope of loss: the list of work the carrier will pay for. On most jobs, that scope is missing items the roof actually needs.

A supplement is the formal request to add those items. Contractors who supplement well get paid for the full job. Contractors who do not eat the difference or leave it on the table. This playbook covers the whole process.

Why Adjuster Scopes Miss Items

Adjusters work fast, often from the ground or a short inspection, and they write to a standard template. Items that are easy to overlook, such as drip edge, starter, ice and water shield, steep charges, or code required upgrades, are missed constantly.

It is rarely malicious. It is volume and speed. Which means the gap is predictable, and predictable gaps can be systematically recovered.

The Supplement Process, Step by Step

• Get the full adjuster scope in writing before you start.
• Inspect and document the roof yourself: photos of every slope, edge, penetration, and any code issue.
• Compare the scope line by line against what the job actually requires.
• List every missing or underpaid item with a photo and a reason.
• Write the supplement in the format the carrier expects, with clear justification per item.
• Submit, follow up, and keep a log until each item is approved or formally denied.

What Makes a Supplement Get Approved

Evidence and clarity. Each line item needs a photo, a plain explanation of why it is required, and where relevant the code or manufacturer requirement behind it. Vague requests get denied. Documented requests get paid.

The Cost of Not Supplementing

Every missed item is work you do for free or a corner you are pushed to cut. Across a season of storm jobs, unclaimed items add up to a serious amount of revenue that was owed to you and never collected.

Doing It Faster

Reviewing a scope against a checklist of commonly missed items is exactly the kind of repetitive document work that AI document processing now handles in minutes rather than hours. The contractor still decides. The machine does the reading and the first pass.

The Bottom Line

Supplements are not fighting the carrier. They are documenting the job accurately. Build a checklist, document every roof, compare every scope, and submit with evidence. The recovery follows.
