Hail season is coming. Is your roofing company ready?

Every spring, billions of dollars in roof damage go unpaid- not because the storms weren’t severe, but because contractors left money on the table in the supplement process.

• $22B+ annual U.S. hail damage

• 4,611 major hail events per year (avg.)

Hail is the single costliest weather event for the U.S. property insurance industry. For roofing contractors, it represents the largest concentrated revenue opportunity of the calendar year, but only for companies equipped to capture it fully.

01. Understanding the threat.

What exactly is hail season?

Hail season in the United States runs primarily from March through August, with peak activity concentrated between April and June. During this window, warm, moist air masses from the Gulf of Mexico collide with cold fronts descending from Canada, producing the kind of severe supercell thunderstorms that generate large, destructive hailstones.

Hailstones as small as one inch in diameter - roughly the size of a quarter - can fracture asphalt shingles, crack tile roofing, dent metal panels and puncture membrane systems. Stones two inches or larger cause catastrophic, immediately visible damage. 

What makes hail especially dangerous for homeowners is that much of the structural damage is invisible to the untrained eye, leaving roofs compromised for months or years before a leak makes the problem undeniable.

02. Geography

The states where hail hits harder.

The corridor stretching from South Dakota down through Nebraska, Kansas, Oklahoma and into Texas is so consistently battered that meteorologists dubbed it “Hail Alley.” But hail season doesn’t stop there- the Mid-Atlantic, the Midwest and the Mountain West all experience significant hail activity that generates massive insurance claim volume for roofing contractors every year.

03. The revenue problem

Why most roofing companies lose money after a storm

Here’s the uncomfortable truth: after a major hail event, the roofing industry collectively leaves hundreds of millions of dollars on the table. Not because the work wasn't done. Because the insurance supplements weren’t written correctly, submitted completely or followed up on aggressively.

Insurance carriers initial estimates in Xactimate that are often incomplete. They miss line items. They omit code-required upgrades. They undervalue materials and labor. 

A contractor without a supplement process either eats costs silently- reducing margins on every job- or spends their own field staff’s time chasing adjusters and rewriting estimates during the exact period when production demand is at its absolute peak. 

“Hail season is when roofing companies make their year. But without a structured supplement process, many are working harder than ever and seeing less margin than they should. Every underpaid claim is revenue that was earned and never collected.”

The problem compounds during peak season. Storms hit back-to-back. Crews are slammed. Sales reps are in the field from sunrise to sunset. Office staff are overwhelmed with scheduling and customer calls. In this environment, supplement writing- the specialized, detail-intensive work of line-by-line estimate review- gets rushed, delegated to unqualified staff, or simply skipped. The result is chronic under-collection on the highest-value jobs of the year.

04. The solution

Insurance supplement services: what they are and why they matter.

Insurance Supplement Services (ISS) is a specialized back-office function focused on one goal: ensuring roofing and restoration contractors recover every dollar they are owed on insurance-funded projects. At TNA Global, our ISS team works as an extension and administrative side of claim revenue so your field team can stay focused on production.

Xactimate Estimate Review

We audit every carrier-issued estimate line by line, identifying missing items, underpaid quantities, and scope gaps that reduce your payout before you even start the job.

Supplement Writing and Submission

Our specialists prepare professional, well-documented supplement packages that support your scope with code citations, manufacturer specs and photographic evidence.

Adjuster Communication Support

We support your team through the negotiation process– tracking responses, preparing counter-documentation and following up until supplement approvals are secured.

Code Upgrade & O&P Recovery

Code-required improvements and overhead & profit are among the most commonly omitted items on carries estimates. We make sure these are identified and included in every applicable claim.

Claim Tracking & Revenue Reporting

We maintain detailed records of every open supplement, approval status, and payment milestone– giving your team complete visibility into pending revenue.

Scalable During Storm Season

Unlike internal hires, our ISS team scales with your volume. Whether you’re handling 10 claims or 200, we handle the supplement backlog without adding to your payroll.

05. Why TNA Global

A growth partner built for storm season.

TNA Global was built around a simple observation: roofing and restoration contractors are excellent at inspecting roofs, managing crews and satisfying customers- but the insurance claims process is a completely different discipline that demands specialized expertise most contractors don’t have in-house.

Our ISS team operates as a dedicated extension of your business. We’re aligned to U.S. time zones, integrated with your CRM and structured around your workflow- not a generic call center model. We handle the supplement backlog so your people can stay in the field, on the roof, and in front of your customers during the busiest months of the year.

Combined with Sales Development Representatives who can help fill your inspection calendar during a storm season and our Customer Service Representatives who ensure no inbound call goes unanswered, TNA Global provides a unified revenue engine for growth-focused roofing companies, from first contact through final claim payment.

“Revenue generation. Revenue protection. Revenue optimization. Those three pillars - SDR, CSR and ISS- are what separate roofing companies that scale from those that just survive storm season.”

Don’t let this hail season pass without a supplement strategy.

The storms are coming regardless. The question is how much of that revenue your company will actually collect.
