Insurance Adjuster’s Estimate Lower Than the Contractor’s? Here’s What to Do
When the insurance adjuster’s estimate comes in thousands below your contractor’s bid, it’s almost never the final word — it’s usually a scope gap you fix with documentation and a supplemental claim. Adjusters write fast, standardized estimates (in Xactimate) and routinely miss slopes, accessories, code items, and labor complexity. The fix isn’t arguing about the total; it’s comparing the two estimates line by line and proving what’s missing. Here’s the process.
Why Is the Adjuster’s Number So Much Lower?
Common, fixable reasons:
| Gap | Example |
|---|---|
| Missed scope | Skipped a slope, gutters, detached garage, or flashing |
| Underpriced line items | Local labor/material costs higher than the default pricing database |
| Missing accessories | Drip edge, ridge vent, ice-and-water shield, pipe boots |
| No steep/high charges | Steep or multi-story roofs cost more to work safely |
| Code upgrades excluded | Re-nailing, decking, underlayment now required by code |
| Depreciation confusion | You’re comparing the ACV check to a full RCV bid |
That last one is huge: if your settlement is ACV, the first check is intentionally lower because depreciation is held back and released later. Make sure you’re comparing apples to apples before you cry foul.
Step 1: Get Both Estimates Itemized
You need line-item detail from both sides. Ask your contractor for an itemized estimate — quantities, materials, labor per task — not a lump sum. Then request the adjuster’s full Xactimate report (you’re entitled to it). Lay them side by side.
Step 2: Build the Gap List
Go line by line. For every item your contractor includes that the adjuster’s scope omits or underprices, note it with a photo and the reason it’s required. This becomes your supplemental claim package. If the adjuster’s per-unit prices are simply low, your contractor can document local market rates.
Step 3: Submit a Supplement, Not a Complaint
Don’t call to argue about the total. Submit a documented supplement: the itemized gaps, photos, and your contractor’s estimate, referencing the claim number. Insurers approve labeled, line-by-line supplements far faster than they respond to “your estimate is too low.” Full process: how to file a roof claim supplement and why Xactimate estimates come in low.
Step 4: Escalate If It Stalls
If a real gap is denied:
- Invoke the appraisal clause in your policy — each side picks an appraiser, and an umpire settles disputes. It’s faster and cheaper than litigation.
- Hire a public adjuster for large gaps — they work for you (typically 5–15% of the claim) and re-scope the loss.
- File a complaint with your state Department of Insurance if you believe the claim is being handled in bad faith.
A Warning About “We’ll Match Your Insurance” Contractors
Be wary of a contractor who promises to “do it for whatever insurance pays” or to “waive your deductible.” The first often means cut corners; the second is insurance fraud. A legitimate contractor documents the real scope and helps you supplement it — they don’t make the gap disappear by lowering quality.
Frequently Asked Questions
Why is the insurance estimate lower than my contractor’s bid? Usually a scope gap: the adjuster’s standardized estimate missed slopes, accessories, steep charges, or code items, or priced labor below local rates. Sometimes it’s just that you’re comparing a depreciated ACV check to a full replacement bid. Compare line by line to find the real difference.
Do I have to use the contractor the insurance company recommends? No. You can hire any licensed contractor you choose. The insurer’s payout is based on the cost to repair, not on which contractor does the work — so pick on quality and license, and supplement the claim if the scope is short.
What is a supplemental claim and how does it help here? It’s a request for additional payment on your open claim for items the original estimate missed or underpriced. You submit your contractor’s itemized estimate and photos for each gap. It’s the standard, non-confrontational way to close the difference between the two estimates.
Can I just keep the insurance money and not do all the repairs? With an ACV settlement you may keep the initial check, but you only collect the held-back recoverable depreciation if you actually complete the work and submit invoices. Skipping repairs also risks a coverage problem on the next claim and can violate your mortgage terms.
When should I hire a public adjuster? When the gap is large, the insurer won’t move on documented items, or the claim is complex. Public adjusters work for you for a percentage of the claim. For smaller gaps, a well-documented supplement or the policy’s appraisal clause is usually enough.
