Over the past decade, property insurance carriers and restoration contractors have poured immense resources into automating workflows for operational efficiency.

On the carrier side, modern adjuster dispatching and claims management platforms, digital First Notice of Loss (FNOL) applications, and automated payment settlement solutions have radically compressed cycle times at the bookends of a claim—from initial scoping to final payout. On the contractor side, mobile field documentation, room scanning, and digital job management tools have streamlined onsite workflows.

The parts of the workflow that don’t require external collaboration have been sufficiently automated and streamlined.

Yet, despite heavy investments across the ecosystem, a critical phase in the middle of the workflow has remained untouched by digital transformation: the supplement.

After insurers hand off approved estimates and scoping to the restoration or remediation phase, progress often screeches to a halt. When onsite contractors find that necessary repairs exceed original carrier estimates, work must pause while supplements await review and approval.

Until now, claims automation technology simply hasn’t been designed to streamline these supplement requests and approvals. As a result, the claim drops out of modern software suites and into a tangled web of shared email inboxes, disparate spreadsheets, and disconnected PDFs.

Supplements have quietly become property claims’ last manual frontier. As supplement volume and process complexity put pressure on claims teams, the entire insurance ecosystem urgently requires dedicated solutions built specifically to master the supplement challenge.

Insurers cannot future-proof their claims operations as long as supplements remain a digital afterthought, which is why Cotality has officially launched a powerful supplement management platform that brings structure to intake, routing, review and reporting.

This purpose-built solution streamlines supplement management and collaboration for both insurers and restoration contractors.

The Varied Costs of Manual Supplement Processes

Common methods for submitting and receiving supplements still rely on traditional email inboxes paired with an ad-hoc, “all-hands-on-deck” response. But lacking a sophisticated digital strategy for managing supplements exerts a compounding toll across the entire property ecosystem.

1. Elongated claims lifecycles

When a contractor discovers additional scope and submits an updated estimate, adjusters must first notice it in a shared inbox, and then manually locate the original file, compare line items, request missing photos, and negotiate differences. It’s a seemingly endless loop of “stare, compare… and often times, despair.”

In day-to-day operations, this administrative friction routinely adds two to four weeks to the claim lifecycle. During catastrophic (CAT) storm deployments, when regional claims operations are overwhelmed, triage backlogs can stretch this delay by six to 12 weeks. For a homeowner living amidst exposed framing or tarped roofs, every day is a strike against their customer satisfaction.

2. Pervasive claims leakage

The financial consequences are staggering. According to industry research published by Insurance Thought Leadership, claims leakage accounts for approximately 6% of total claim payments across the industry, costing U.S. insurers an estimated $67 billion annually.

In property claims, a substantial portion of this leakage originates directly within the supplement cycle. When overworked adjusters are forced to manually parse through multi-page estimates under strict time pressures, they are bound to overlook unverified scope differences, overlapping labor charges, duplicate line items, and missing supporting documentation.

3. Relationship erosion

Not only do supplements contribute to adjuster burnout, but the relationships between insurers and contractors suffer because of broken supplement processes. When contractors feel left hanging, their trust in carriers deteriorates.

Contractors face disrupted cash flow waiting for approvals on work that must proceed, while carriers feel pressured by escalating loss adjustment expenses (LAE). Caught in the middle is the policyholder, whose frustration mounts with every unnecessary delay.

Transforming Chaos into Intelligence: Cotality Supplement™

This October, Cotality introduced Cotality Supplement™, a supplement automation platform that reimagines the supplement workflow, from intake to line-item review, and providing upstream analytics.

• Estimate intelligence: Instead of requiring adjusters to manually cross-reference 50-page line-item reports, the platform can automatically flag exact line-item discrepancies, quantity variances, and price modifications between the original estimate and the supplement. Adjusters can identify key differences more efficiently.
• Rule-based workflow routing: Configurable business rules help direct supplement submissions to the appropriate reviewers, reducing manual inbox triage and creating a more consistent review process.
• Actionable analytics and trend visibility: Carriers gain real-time visibility into the root causes of supplements. By tracking supplement volume, workflow activity, turnaround trends, and intake data, leadership gains greater visibility into supplement operations and opportunities for process improvement.
• Flexible workflow integration: Cotality Supplement is designed to fit within existing claims workflows, helping carriers introduce a more structured supplement process without disrupting established operations.

By replacing unstructured inbox chaos with a centralized workflow, carriers can spend less time managing submissions and more time reviewing the ones that really need it. All the while, contractors get clearer, quicker path for supplement requests and leadership can instantly glean insights into operational trends.

The rising stakes: Why supplement automation is urgent

Addressing the supplement challenge is no longer optional. As severe convective storms—bringing devastating hail, high winds, and torrential rainfall—continue to increase in both frequency and severity, they are driving record-breaking losses to roofing and housing exteriors across North America.

All the while, at least 40% to 60% of all exterior and roofing claims require a supplement once restoration work actually begins.

While the U.S. experienced a lighter hurricane season in 2026, severe weather remains highly unpredictable, and the coming year promises no relief from convective storm volatility. With hail not treating every roof the same way, damage variance is high—and managing more than half of your property claims through manual inboxes is no longer a sustainable strategy.

Optimizing the entire claims lifecycle

For years, the industry automated intake and settlement while leaving the workflows in the middle suspended between insurers and contractors.

With Cotality Supplement, that missing piece is finally in place. By turning fragmented, disorganized document exchange into a structured workflow, carriers and contractors can reduce unnecessary back-and-forth, improve visibility, and help claims move toward resolution faster, and with greater clarity.
