Commercial Hail Claim Timeline: From Storm to Settlement (the Roof Side)
By Blake Snow, experienced roof consultant
A commercial hail claim can take a long time to move from the day of the storm to a settled number and a finished roof. Much of that time is spent on the roof questions: what was damaged, how badly, and what it will take to fix. This article walks through a typical commercial hail claim from the roof side only. It doesn't cover coverage, legal strategy or policy interpretation; those belong with your carrier, agent and attorney.
Every claim is different, and the order of steps varies. Think of this as a map of the roof work that usually needs to happen.
1. The storm and the first days
Right after a hailstorm, the priorities are safety and preventing further damage. Check for active leaks, protect the interior, and make temporary repairs if needed to stop water entry. Document what you do: photos of leaks and temporary repairs, and receipts.
From the roof side, it also helps to limit foot traffic until the roof has been documented. Every trip across a single-ply or soft roof can leave marks that later have to be sorted out from hail. Keep maintenance and repair records, warranties and any prior roof reports handy; they'll be needed.
2. Notice and the first inspection
Policies usually require prompt notice of a loss. Your agent, carrier or attorney can tell you what applies. After notice, the carrier will typically arrange an inspection, and the owner may bring in its own roof consultant.
On a large building, the first inspection should establish the basics: how many roof sections there are, what systems and layers, approximate ages and condition, and where hail evidence is visible, including on rooftop equipment and soft metals.
3. Roof inventory and documentation
For large losses, a roof inventory is one of the most valuable early steps. Each section gets an ID on a roof plan, with its system, size, slope, attachment and condition. Photos and later test results are tied back to that plan. When everyone uses the same plan, it's much easier to discuss the claim section by section rather than arguing about "the roof" as a whole.
4. Testing
Because hail damage on low-slope roofs can hide beneath the surface, testing is often needed. Core cuts confirm the roof assembly and the condition of cover board and insulation. Infrared moisture surveys help map possible wet insulation across large roof areas. Testing should be documented with locations, photos and results, and done with the owner's permission.
5. Cause and repairability
With documentation and test results in hand, the roof questions come into focus:
- Which sections show damage consistent with hail?
- What damage is from age, wear, foot traffic, prior repairs or installation issues instead?
- For damaged sections, can the roof be repaired effectively, or does it need replacement or recovery?
- Are the original products still available, and what does the manufacturer's warranty require?
- Do local building code requirements affect the scope?
This is where clear written reasoning matters most. See our forensic roof consulting page for how we approach these questions.
6. Scope of work and estimates
Once the parties understand what's damaged, someone has to describe the work: a scope with quantities that matches the actual roof assembly, section by section. Estimates built on the wrong assembly, wrong quantities or the wrong system are a common source of disputes. A good scope covers tear-off or recover, insulation and cover board, membrane, flashings, edge metal, rooftop equipment handling and other details a contractor would need to price the job.
7. Disagreements
It's common for the owner's and carrier's estimates to differ. Many differences can be narrowed by walking the roof together, comparing documentation section by section, and checking that both estimates describe the same roof. Separating cause questions from cost questions helps keep the conversation productive.
8. Appraisal, if it comes to that
If the parties agree a loss is covered but can't agree on the amount, many policies offer appraisal. Each side picks an appraiser, the appraisers select an umpire, and an award signed by two of the three typically sets the amount of loss. See our article on how the roof appraisal process works.
9. Settlement and the work
Once the amount is settled, the roof work can be planned. On large buildings, that means specifications, bidding, scheduling around operations, and inspection during construction. A clear specification and a review of contractor bids against it help make sure the finished roof matches what was scoped. Our sister company's commercial roofing page describes the systems commonly installed.
Working with consultants on both sides
On large losses, it's common for the owner and the carrier to each have a roof consultant. That doesn't have to slow things down. When both consultants inspect together, agree on a roof plan and section IDs, and share test locations and results, the disagreements usually narrow to a few specific questions. Those are much easier to resolve, whether by discussion, by additional testing, or, if needed, in appraisal.
It also helps when each report states clearly what was examined, what tests were performed, and what wasn't looked at. Gaps in documentation tend to become disputes later.
What slows claims down on the roof side
- No roof plan, so parties talk past each other about which areas are which
- Foot traffic and later damage mixed in with storm damage
- Missing maintenance and repair records
- Estimates based on the wrong roof assembly
- Testing done without documented locations
