The Xactimate roofing supplement list

Additional-layer tear-off (per layer above one)

Each extra layer is its own Xactimate line; adjusters routinely scope a single layer sight-unseen.

Replace damaged decking / sheathing (per sheet)

Unknowable until tear-off — agree on a per-sheet unit price up front, then supplement actuals.

Re-nail deck to current code

Code-required in high-wind jurisdictions; cite the local code section.

Additional dumpster / haul trips

Multi-layer and tile jobs exceed one dumpster; keep the weight tickets.

Ice & water shield — eaves to warm wall

Cold-climate code requires coverage past the exterior wall line — usually more than the scoped 24".

Ice & water shield — valleys (per LF)

Separate line from eave coverage; commonly collapsed into it or dropped.

Ice & water shield — penetrations & skylights (each)

Priced per penetration, not per LF; almost never on initial scopes.

Synthetic underlayment upgrade

Where code or manufacturer spec requires synthetic over felt, the price delta is claimable.

Starter strip — eaves (per LF)

A separate Xactimate item from field shingles; scopes often assume cut three-tabs.

Starter strip — rakes (per LF)

The single most commonly missed item on storm scopes. Different line from eave starter.

Hip & ridge cap (per LF)

Priced well above field shingles per LF; verify the quantity against actual hip/ridge length.

Class 4 impact-resistant upgrade

When the policy endorsement or local code requires IR shingles, the premium is a line item.

6-nail high-wind pattern

Code upgrade in wind zones — changes labor and material quantities.

Drip edge — eaves and rakes (separate LF lines)

Two lines, two prices. Scopes that include one almost always omit the other.

Step flashing at sidewalls & dormers (per LF)

Code-required at every roof-to-wall transition; a near-universal supplement.

Chimney base AND counter flashing (two lines)

Don’t let them be bundled — they’re separate labor operations in Xactimate.

Chimney cricket / saddle (chimneys over 30" wide)

IRC requirement — measure and photograph the chimney width.

Headwall / endwall flashing (per LF)

Where a roof plane dies into a vertical wall; frequently absent from scopes.

Pipe boots — standard vs. large-diameter (each)

Different unit prices; count every penetration on the photo set.

Open valley metal (per LF)

If converting from woven, document why (manufacturer spec, code, or match).

Ridge vent (per LF)

Verify against actual ridge length, not the scope’s estimate.

Box / turtle vents (each, removal + install)

Hail-dented vents are replacement items — close-up photos win this line.

Turbine vents (each)

Bent or seized after hail; spin test on video is compelling documentation.

Detach & reset attic fan / power vent

D&R applies when intact units sit in the work area; replacement if damaged.

Gutter apron (per LF)

Distinct from drip edge; prevents fascia rot and is code-referenced in many areas.

Gutters & downspouts — D&R vs. replace

Two different lines; hail spatter photos justify replacement over reset.

Gutter guards — detach & reset (per LF)

Significant labor that initial scopes almost never carry.

Window wraps, screens, and soft metals

Collateral hail damage on elevations facing the storm; photograph during inspection.

Steep-slope charge (7/12 and up)

Verify pitch with a gauge photo; adjusters estimate low from the ground.

Additional steep charge tiers (10/12+, 12/12+)

Steeper tiers pay more — one gauge photo per plane settles it.

High roof / two-story charge

Separate from steep; applies to staging and safety on upper roofs.

Limited access / hand-load charges

Rear yards, no driveway access, HOA restrictions — document the condition.

Overhead & profit (O&P)

Justified when the loss requires coordinating three or more trades — roofing, gutters, painting, etc.

Recoverable depreciation request

Not automatic — submit completion docs and formally request the holdback.

Aerial measurement report fee

A legitimate claim expense when ordered to support scope accuracy.

Code-upgrade (ordinance & law) items

Cite the exact local code section; O&L coverage pays for code-driven deltas.
