How to Write a Roofing SupplementMost denied supplements fail for the same reasons: missing photos, unclear scope gaps, pricing outside carrier norms, or submission to the wrong channel. This is the step-by-step process — and the documents Contractorfy produces from the live inspection call that short-circuit most of it.
Process aligned with BossUp Solutions, Roof Sales Mastery, and Cedur’s public supplement guidance — executed automatically by Contractorfy from the call itself.

Before the supplement exists, the evidence has to. Most denials trace back to thin documentation.
The supplement exists because the carrier’s scope is incomplete. Prove it line-by-line.
Carriers expect to see their own line-item language and pricing logic. Non-Xactimate estimates get kicked back.
Code citations move a supplement from “request” to “requirement.”
Right document, wrong channel = denial. Every major carrier has a preferred supplement submission path.
Frequently asked questions
Insufficient documentation. Adjusters deny what they can’t see. Slope-by-slope photos, a measurement report, and code citations for every added line solve 80% of denials.
Carriers overwhelmingly expect Xactimate-aligned line codes and pricing. You can submit in other formats, but expect more friction and kickbacks. Contractorfy drafts supplements in Xactimate-aligned format.
4–8 hours typical: 1–2 hours inspecting, 1–2 comparing the scope, 2–3 drafting the supplement and letter, 30 min submitting. Contractorfy reduces this to the inspection call itself.
IRC R905 (roof coverings), R806 (ventilation), local amendments on ice-and-water membrane, and manufacturer specs for warranty preservation. State-specific codes when applicable.
Stay within the carrier’s regional pricing database (Xactware/CoreLogic) for standard lines; for unusual lines, reference your own approved-claim history. Contractorfy flags pricing that falls outside historical norms before you submit.
Use structure and section order (BossUp Solutions and Roof Sales Mastery both publish strong frameworks), but the line items and code citations must reflect your actual inspection findings. Generic templates get denied.
