What Is a Supplement?
A supplement is a formal request to the insurance carrier to approve additional line items not included in the original Summary of Damages. Common supplements in roofing include code upgrades, ice and water shield, permit fees, drip edge, and additional material costs. Supplements are submitted to the carrier for approval before the additional work is added to the approved scope.
Important Distinction
Note: A supplement is a documented request for scope the original estimate did not capture — it is not a price increase, a renegotiation of the settlement, or a vehicle for work the loss did not require. Each item is approved or declined by the carrier, not by whoever submits it — and not by Zilker Roofing: we document the scope, we do not negotiate your claim or decide what your policy pays.
