Some line items get left off adjuster’s estimates for reasons that are legitimate scope gaps, and some get left off because they simply aren’t required for the specific damage or roof in question. The reading-your-adjuster-estimate guide covers the checklist of items to look for. This post covers, for each of those items, why it might be missing and how to tell whether it’s genuinely owed on your roof. Requesting a supplement for items that aren’t actually required for your specific job is time spent for nothing - the supplement gets rejected, and correctly.
Why Items Get Left Off in the First Place
Broadly, three reasons:
- The adjuster missed it. Something visible and required that simply didn’t make it onto the estimate. This is what a supplement is for - see How to Request a Supplement on Your Roof Claim for the mechanics.
- It’s bundled into another line. Some pricing services combine items - underlayment might be included in the shingle-install price rather than listed separately. The item is being paid for; it just doesn’t have its own row.
- It genuinely doesn’t apply to your job. A partial repair doesn’t need a full-perimeter drip edge replacement. A single-story ranch with an easy pitch doesn’t need a steep-slope access charge. A jurisdiction with no permit requirement for this scope doesn’t need a permit fee. A supplement request for an item that isn’t actually required for your specific work will get declined - and the decline is correct.
Working through each item below, the question isn’t “is it on the estimate” - it’s “is it required for my specific roof, and if it is, is it either present or bundled somewhere else.”
Tear-Off and Disposal
What it is: removing the existing roofing material and disposing of it, typically priced per square (100 sq ft of roof surface).
When it should appear: on any full replacement or on repairs where the damaged material has to come off before new material goes on.
When it might legitimately be absent or bundled: on a partial or overlay repair where the existing material stays in place, or when the pricing service bundles it into the install line. If the estimate has an install-shingles line but no tear-off line, ask whether tear-off is included in the install price before assuming it’s missing.
What documentation confirms it’s owed: contractor line-item showing tear-off priced separately for the same scope, and photos of the material being removed.
Underlayment
What it is: the layer of felt or synthetic material installed between the roof deck and the shingles.
When it should appear: whenever shingles are being installed on the affected area. Underlayment is replaced with a shingle replacement in nearly all cases - a new shingle over old, weathered underlayment isn’t a like-kind repair.
When it might legitimately be absent or bundled: rarely for a full replacement. If it’s not on the estimate for a full re-roof, that’s a real question to ask.
What documentation confirms it’s owed: contractor specification of the underlayment type and quantity, and the manufacturer’s install requirements for the shingle being used (nearly all shingle warranties require specific underlayment).
Drip Edge
What it is: the metal strip installed along the roof perimeter (eaves and rakes) to direct water into the gutter and away from the fascia.
When it should appear: on a full replacement in any jurisdiction that requires it by code - which is common but not universal. Also required by many shingle manufacturers’ installation instructions for warranty coverage.
When it might legitimately be absent: on a partial repair that doesn’t touch the perimeter, or in a jurisdiction that doesn’t require it and where the existing drip edge is being reused (though most contractors will replace it as part of a re-roof anyway).
What documentation confirms it’s owed: your local code requirement, the manufacturer’s install instruction, and linear-foot measurement of the affected perimeter.
Flashing
What it is: metal sealing at roof penetrations (chimneys, vent pipes, skylights) and intersections (valleys, roof-to-wall abutments) to keep water out where the shingle field is interrupted.
When it should appear: whenever the affected area includes a penetration or intersection. Existing flashing that gets disturbed during shingle removal is typically replaced, not reused.
When it might legitimately be absent: if the damaged area doesn’t include any penetration or intersection, no flashing line is needed. Also, some estimates itemize step flashing, counterflashing, valley flashing, and pipe boots separately; others use a single “flashing” line - check whether specific pieces are itemized before treating any of them as missing.
What documentation confirms it’s owed: photos of the specific penetrations or intersections in the affected area, and contractor line-item pricing for each type of flashing needed there.
Ridge Cap and Starter Strip
What it is: the shingles that cap the ridge line at the top of the roof (ridge cap) and the specialized shingles installed at the eaves as the first course (starter strip). These are separate products from field shingles.
When it should appear: whenever the affected area includes the ridge (ridge cap) or the eaves (starter). On a full replacement, both should be on the estimate.
When it might legitimately be absent: on a partial repair that doesn’t touch the ridge or eaves.
What documentation confirms it’s owed: the shingle manufacturer’s install instructions (which typically require both), and photos or measurements showing the affected area includes the ridge or eaves.
Permit Fees
What it is: the fee your local jurisdiction charges for a building permit, if one is required for a roof replacement.
When it should appear: in jurisdictions that require permits for the scope of work being done. Requirements vary widely - some jurisdictions require permits for any roof work, others only for full replacements, others for none.
When it might legitimately be absent: in a jurisdiction that doesn’t require a permit for the specific scope. Also - and this is worth checking specifically - whether permit costs are covered by your policy is a separate question from whether the work requires a permit. Some policies include permit fees under a code-upgrade or ordinance endorsement; others don’t cover them at all. How to Read Your Declarations Page covers where to check.
What documentation confirms it’s owed: the jurisdiction’s permit requirement (usually available on the building department’s website), and the actual permit application or receipt if the work has already been permitted.
Steep-Slope and Multi-Story Access Charges
What it is: additional labor and equipment charges for roofs above a certain pitch (steep-slope, typically 7:12 or 8:12 and above depending on the pricing service) or above a certain height (second story or above). These reflect the additional staging, safety equipment, and slower work required.
When it should appear: when your roof meets the pitch or height threshold the pricing service uses. Some pricing services apply these automatically based on measured pitch and story count; others require them as a separate line.
When it might legitimately be absent: on a low-pitch, single-story roof - these charges genuinely don’t apply. Or on an estimate where the pricing service has already factored the access difficulty into the unit costs.
What documentation confirms it’s owed: the actual pitch measurement of your roof and the story count, plus the pricing service’s own threshold for triggering the charge - if the pricing service the adjuster used treats a 6:12 pitch as normal and yours is 6:12, no steep-slope charge is owed even if a contractor’s separate pricing does apply one.
Before Requesting a Supplement, Check Your Own Numbers
For any item you believe is missing, the honest question is whether that item is required for your roof, not whether it appears on a general checklist. A supplement for a genuinely-owed item works; a supplement for an item that doesn’t apply gets declined, correctly.
Before assembling a supplement, know what the total claim math actually supports. Check how much a supplement’s added line items would actually move your net payable, given your roof’s age and deductible - if the calculator’s output roughly matches what you received, adding items may not change the net payable much once depreciation and the deductible have already accounted for most of the gap. Sometimes what feels like “the estimate is missing items” is actually “depreciation on an older roof is doing what depreciation does.”
If you’ve worked through this list and identified specific items that are genuinely required for your roof, and the estimate doesn’t include them and doesn’t bundle them, that’s the case a supplement can actually resolve - and How to Request a Supplement on Your Roof Claim covers exactly how to put that request together so it gets approved.
