In 15+ years of processing insurance supplement claims for Chicagoland roofing contractors, one thing has remained consistently true: insurance carriers underestimate roofing claims. Not sometimes — on nearly every job.

This isn't necessarily a conspiracy. Adjusters are not roofing experts. They work from standardized pricing software with regional averages that often don't reflect actual local costs. They evaluate dozens of properties per week and move fast. And they have no financial incentive to make sure your estimate covers every legitimate line item.

The result is that Chicagoland roofing contractors — doing legitimate, code-compliant work — routinely get paid less than the job actually costs. Here's what carriers miss most often and how to fight back professionally.

The 8 Most Common Gaps on Illinois Roofing Claims

1. Overhead & Profit (O&P)
Carriers frequently exclude O&P on jobs that clearly involve general contractor coordination. This is one of the most consistently missed and most consistently recoverable items on any claim.
2. Illinois Code Upgrades
Drip edge, ice and water shield, ridge vents, and other code-required components vary by municipality across Chicagoland. Adjusters from outside the area routinely miss these entirely.
3. Incorrect Labor Rates
Xactimate's default labor rates for Illinois are often set below actual market costs — particularly after major storm events when roofing labor demand spikes throughout the region.
4. Improper Depreciation
On RCV policies, recoverable depreciation is frequently withheld beyond the appropriate timeframe or calculated incorrectly on specific line items, reducing the contractor's final payment.
5. Damaged Accessories
Gutters, fascia, skylights, pipe jacks, vents, chimney flashing, and satellite dish remounting — all commonly damaged in hail and wind events — are routinely absent from initial estimates.
6. Permit Fees
Every municipality in Chicagoland requires permits for roofing replacements. These fees are a legitimate, recoverable cost that adjusters frequently fail to include in their initial estimates.
7. Disposal & Haul Away
Tear-off debris disposal costs are sometimes underestimated or omitted, particularly on larger commercial jobs where disposal volumes are significant.
8. Steep Slope Charges
Roofs with steep pitches require additional labor time and safety equipment. Adjusters frequently apply incorrect pitch multipliers or miss steep slope charges entirely on complex residential roofs.

Why This Happens in Illinois Specifically

Illinois has some unique factors that make underestimation particularly common compared to other states:

How to Fight Back — Professionally and Effectively

The key word is professionally. Carriers respond to documentation, not frustration. Every supplement item needs to be supported by photos, measurements, code citations, and a clear written justification. Vague requests get rejected. Documented, professionally presented supplement packages get approved.

What a successful supplement package includes:

→ Revised Xactimate estimate with every line item clearly justified

→ Photos documenting each claimed item of damage or required upgrade

→ Local building code citations for code-required items

→ Current permit fee schedules for the specific municipality

→ Labor rate justification for Illinois market conditions

→ Written narrative explaining the basis for each supplement item

When a carrier still refuses after a properly documented supplement — which does happen — the formal appraisal process provides a legitimate legal mechanism to resolve the dispute. This is not litigation. It's a structured process defined in the insurance policy itself, and it's highly effective when handled by experienced professionals.

What This Means for Your Bottom Line

For a Chicagoland roofing contractor doing 20-30 insurance jobs per season, the cumulative impact of unrecovered supplements is enormous. Even conservatively assuming $5,000 in recoverable new money per job, that's $100,000-$150,000 in legitimate revenue being left on the table every season.

That's not money you need to hustle for. It's money that's already owed to you on work you've already done or are about to do. The only question is whether someone with the expertise to identify and recover it is working on your behalf.
