Why Xactimate Codes Matter for Supplements
When you submit a supplement request, you need to reference the exact Xactimate line item code for each missing or underpaid item. Using the correct code signals to the carrier's reviewer that you know the system — and makes it harder to deny your request.

How to Use These Codes in a Supplement
When you identify a missing item, reference the code in your supplement letter like this:
> "The carrier estimate does not include starter course shingles (RFG SSTARTER). Per GAF's Shingle Application Manual, starter strip is a required installation component. Requested: 12 SQ × $18.00 = $216.00."
