Xactimate Codes for Roofing Supplements: Quick Reference

This is the short list of line items that come up most often on roofing supplements, with the unit each one is measured in. The prices shown are national-average examples for illustration. Your price list, region and date will differ, so always use the price list named on the adjuster's estimate.

The sections below explain when each item applies and what proof to attach. If you are assembling a package, run it against the free supplement checklist before you send it. To see these items laid out in a full package, read the Xactimate roofing estimate example, and for how estimating software and documentation tools fit together, see Xactimate roofing software explained.

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 is easier for the adjuster to review. Approval still depends on the claim, the policy and the carrier.

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 many building codes (check your local code) 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.

Codes only help if you pick the right one. In Xactimate, roofing items live in the roofing category, and each item has a description, a unit of measure and a unit price from the price list you are working in.

Follow these habits every time:

The code names and prices shown in this guide are shorthand examples. Always confirm the exact item and price in your own software or with the adjuster.

Missing a small item costs little on one job and a lot across a year. These are the ones crews and estimators overlook most often:

Walk this list before you finish any estimate or supplement. It takes a minute and often finds items worth hundreds of dollars.

Unit prices in Xactimate come from regional price lists that are updated regularly. The same item can carry a different price in two nearby cities, and the price for the same city changes over time.

Three practical rules:

The example prices in the table above are national-style averages and will not match your area. Treat them as a sanity check, not a quote.

A code tells the adjuster what you want. The proof tells them why. For every code on a supplement, attach at least:

When all three are present, the line item is much easier for the adjuster to verify without a call. For a full workflow, see how to write a roofing supplement and our photo documentation checklist.

Supplement Snap suggests a matching Xactimate line code, with sub-items and a unit price, for each damage type your crew captures. When you export the Xactimate-style CSV, each capture produces suggested line items. The crew's quantity and an approximate price from a fixed table of illustrative figures are filled in only for the first item, and only when the unit your crew chose matches the unit of that price. Other rows are left blank for you to complete. Review every row against your own price list before you send.

For example, a 'Decking' capture suggests both the sheathing replacement line (RFG SHTHN) and the felt underlayment line (RFG RFLT30). A 'Multiple Layers' capture suggests 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 helps keep items from being missed in the export.
