Xactimate Codes for Roofing Supplements: Complete Reference

Insurance adjusters use Xactimate to estimate repair costs. When you submit a supplement using the same line codes and format the adjuster works in, your supplement gets processed faster and has a higher approval rate.

Submitting a supplement as a plain-text description forces the adjuster to translate your findings into Xactimate themselves, which means they might use lower-cost codes, miss line items, or simply deny the supplement because it's too much work to process.

When rotted or damaged decking is found during tear-off:

Always measure the actual area of damaged decking. Count sheets if possible; a standard sheet is 4x8 (32 SF). Include photos showing the rotted wood with context of where it sits on the roof.

For failed or corroded flashing:

Document the type of flashing (step, counter, valley), the material (aluminum, galvanized), and the location (chimney, wall, skylight). Photograph both the removed flashing and the area it was protecting.

For missing or deteriorated ice and water membrane:

This is one of the most common supplement items because many older roofs were installed without ice and water shield in areas where current building codes now require it (valleys, eaves, around penetrations). Always reference the applicable building code in your supplement narrative.

For damaged pipe boots and roof vents:

Pipe boots deteriorate over time and are often cracked or separated when discovered during tear-off. Document each pipe boot individually with photos.

For missing or damaged drip edge:

Drip edge is required by most building codes and is a common supplement item when the original installation didn't include it or it has corroded.

For roofs with multiple layers:

Multiple layers are only discovered during tear-off. Document the number of layers found and photograph the cross-section showing multiple layers of shingles.

Supplement Snap automatically maps each damage type to the correct Xactimate line codes with sub-items and unit pricing. When you export the Xactimate CSV, each capture generates the appropriate line items with quantities and national average pricing.

For example, a 'Decking' capture automatically generates both the sheathing replacement line (RFG SHTHN) and the felt underlayment line (RFG RFLT30). A 'Multiple Layers' capture generates both the tear-off line (RFG TEAR) and the haul debris line (RFG HAUL).

This saves your office staff from manually looking up codes and pricing, and ensures nothing gets missed in the export.
