Key Takeaways
- A leak is not the only sign of storm damage. Hail and wind can compromise TPO, PVC, EPDM, built-up, and metal roofing systems in ways that may not cause interior water intrusion for months or even years.
- Documentation is your strongest asset. Pre-storm inspection reports, maintenance records, roof photos, and a roof access log establish the roofing system’s condition before the storm and support a smoother claims process.
- Your contractor and your insurer have different roles. A commercial roofing contractor documents damage and explains proper repair or replacement, while your insurance company determines coverage under your policy.
- Manufacturer-backed warranties add third-party credibility. Documented attachment requirements and a final manufacturer inspection provide independent proof of how the roof was installed and accepted before the storm.
- Act quickly, but repair carefully. Schedule a professional inspection after significant hail or wind—even without a leak—and avoid permanent repairs that could eliminate evidence or void an existing warranty.
Missouri weather can be hard on commercial roofs.
Hail, high winds, tornadoes, heavy rain, falling limbs, and wind-driven debris can damage a roofing system in a matter of minutes. The difficult part is that commercial roof damage isn’t always obvious immediately after the storm.
Your roof may not be leaking.
That doesn’t necessarily mean it wasn’t damaged.
For commercial property owners, knowing what to do before and after a storm can make a major difference when evaluating roof damage and working through an insurance claim.
Your Roof Doesn’t Have to Leak to Be Damaged
One of the biggest misconceptions we hear from building owners is:
“My roof isn’t leaking, so I don’t think the storm hurt it.”
A leak is only one indication of roof damage.
Different commercial roofing systems respond to storms differently.
Hail can damage TPO and PVC membranes, compress insulation beneath adhered EPDM systems, fracture components of built-up roofs, damage granulated cap sheets, and dent or damage commercial metal roofing.
Wind can affect edge metal, flashing, membrane attachment, fasteners, rooftop equipment, and other components without immediately allowing water into the building.
Some storm damage may not result in a leak until months or even years later.
That’s why a significant storm should be followed by a professional commercial roof inspection rather than simply waiting to see if water enters the building.
Start With Proper Documentation
Once conditions are safe, begin documenting the property.
Take photographs or video of visible damage before cleanup or permanent repairs begin.
For a commercial property, documentation may include:
- Roof damage
- Damaged edge metal or flashing
- Rooftop equipment
- Fallen limbs or debris
- Interior water intrusion
- Damaged exterior components
If emergency repairs are necessary to protect the building, document the original condition before the work whenever possible. Keep photographs, invoices, and receipts associated with the work.
Have the Roof Inspected by a Commercial Roofing Contractor
Commercial storm damage can be difficult to identify if you don’t understand the roofing system.
TPO, PVC, EPDM, built-up roofing, and commercial metal roofs are constructed differently and exhibit storm damage differently.
A commercial roofing contractor can document the roofing system, physical damage, existing conditions, insulation damage, flashing and edge conditions, repairability, and manufacturer requirements.
The contractor’s job is to evaluate the roof and explain what is required to repair or replace it correctly.
Your insurance company determines coverage under your policy.
Those are two different jobs.
Understand What Your Commercial Insurance Policy Covers
Commercial insurance policies aren’t all the same.
Coverage can depend on your policy, endorsements, deductibles, exclusions, and the cause of damage.
Important items may include wind and hail coverage, deductibles, Replacement Cost Value versus Actual Cash Value, roof limitations, cosmetic damage exclusions, code upgrade coverage, and business interruption coverage.
Your roofing contractor can explain what happened to the roof and what it will take to properly restore the roofing system. Coverage decisions belong to the insurance professionals involved in the claim.
Why Your Commercial Roof’s History Matters
One of the most valuable things a commercial property owner can have after a storm is documentation from before the storm happened.
That may include:
- Previous inspection reports
- Maintenance records
- Roof photographs
- Repair history
- Manufacturer warranty documents
- Approved roofing assembly information
- Roof access logs
Those records establish a history of the roofing system. Without them, everyone involved may be trying to determine the pre-storm condition of a damaged roof after the fact.
Manufacturer Inspections Can Become Important After a Storm
This is one of the less obvious benefits of a manufacturer-backed commercial roofing warranty.
Many manufacturer-backed systems require the roof to be installed according to a specific approved assembly. The manufacturer then inspects the completed roofing system before accepting it for warranty.
Depending on the system and warranty, requirements can include:
- Fastener type and spacing
- Membrane attachment
- Insulation attachment
- Perimeter and corner enhancements
- Edge securement
- Approved components
- Specific wind requirements
If deficiencies are identified during the final inspection, they generally must be corrected before the roof is accepted for warranty.
That creates something extremely valuable:
Third-party documentation that the roofing system was inspected and accepted before the storm occurred.
Why Wind Ratings and Installation Records Matter
Imagine a commercial roof is partially blown off during a major windstorm.
Questions may immediately arise about the original installation.
Was the fastener spacing correct? Was the insulation properly attached? Were the perimeter and corners installed according to the required design?
Was this a properly installed roof overwhelmed by a severe storm, or did an installation problem contribute to the failure?
Without documentation, answering those questions years after installation can be difficult.
Now consider a roof installed under a manufacturer-backed system with documented attachment requirements, a final manufacturer inspection, and specified wind coverage where applicable.
That doesn’t automatically determine insurance coverage or prove the cause of every failure.
But it provides meaningful third-party documentation showing how the roof was required to be installed and that the manufacturer inspected and accepted the completed system.
That’s considerably stronger than relying solely on the installing contractor saying:
“We installed it correctly.”
Keep a Roof Access Log
Commercial roofs are frequently accessed by HVAC technicians, electricians, plumbers, telecommunications contractors, and maintenance personnel.
A simple roof access log should document who accessed the roof, when they were there, why they accessed it, and what work was performed.
If damage is later discovered, that history can help determine what happened and when.
Combined with inspection reports, photographs, maintenance records, and manufacturer documentation, an access log creates a much clearer history of the roofing system.
Protect Your Existing Roof Warranty
Storm damage doesn’t automatically eliminate an existing manufacturer warranty.
But the wrong repair can create warranty problems.
Before allowing someone to cut, patch, alter, or replace portions of a warranted commercial roofing system, determine what the manufacturer requires.
A repair that stops today’s leak isn’t necessarily a repair that complies with the existing roofing manufacturer’s requirements.
Choosing a commercial contractor familiar with the roofing system can help protect the warranty you already paid for.
Don’t Make Permanent Repairs Too Quickly
If a storm opens the roof, preventing additional water damage is important. Temporary emergency repairs may be necessary.
Permanent repairs are different.
Document the conditions, protect the building from additional damage, retain records and receipts, and give the appropriate parties an opportunity to evaluate the loss before permanent work eliminates evidence of what occurred.
When Should You Call Your Commercial Roofing Contractor?
You don’t need to call your roofing contractor every time it rains. But after a significant storm, waiting until the roof starts leaking can be a mistake.
Consider calling your commercial roofing contractor when:
- Your property experiences significant hail
- Winds damage trees, signs, siding, or nearby buildings
- You see loose or damaged edge metal
- Rooftop equipment or flashing has been damaged
- Debris has landed on the roof
- You notice new interior leaks or water staining
- Nearby commercial buildings have experienced roof damage
Remember: a commercial roof does not have to be leaking to have storm damage.
The purpose of the inspection isn’t automatically to file an insurance claim. It’s to determine whether the storm affected the roofing system and document what is found.
If there is no meaningful damage, that’s good information to have.
If damage is found, you now have photographs, inspection records, and a professional assessment before additional weather or normal aging makes it more difficult to determine what happened.
For buildings with manufacturer-warranted roofing systems, contacting your commercial roofing contractor quickly is even more important. Your contractor can determine whether the manufacturer should be notified and help ensure any repairs comply with the manufacturer’s requirements.
Don’t wait for water coming through the ceiling to be your first indication that something happened on the roof.
Choose a Contractor Who Will Be There After the Storm
A major storm can bring a lot of roofing contractors into an affected area.
Commercial property owners should look beyond who can get there first.
Choose a contractor who regularly works with commercial roofing systems, understands manufacturer requirements, can perform manufacturer-approved repairs, has an established local presence, and will still be available after the storm work is finished.
The goal isn’t simply to get through an insurance claim.
It’s to restore the roofing system correctly and protect your building for years afterward.
Final Thoughts
The best time to prepare for a commercial roof insurance claim is before the storm happens.
Maintain the roof. Document its condition. Keep inspection and repair records. Maintain a roof access log. Keep your manufacturer warranty and roofing system information.
Then, after significant hail or wind, have the roof professionally evaluated even if there isn’t water dripping from the ceiling.

Frequently Asked Questions
Can my commercial roof have storm damage even if it isn’t leaking?
Yes. A leak is only one indication of roof damage. Hail can fracture TPO and PVC membranes, compress insulation beneath adhered EPDM systems, damage granulated cap sheets on built-up roofs, and dent commercial metal panels. Wind can loosen edge metal, flashing, fasteners, and membrane attachment without immediately allowing water inside. Some storm damage does not produce a leak until months or even years later, which is why a professional inspection after significant weather is more reliable than waiting for water to appear.
How soon should I schedule a roof inspection after a Missouri storm?
As soon as conditions are safe. After significant hail or high winds, prompt inspection lets you document the roofing system’s condition before additional weather or normal aging makes it harder to determine what happened. Early documentation—photos, inspection records, and a professional assessment—strengthens your position whether or not you ultimately file an insurance claim.
What should I document after storm damage occurs?
Once it is safe, photograph or video all visible damage before cleanup or permanent repairs begin. Capture roof damage, damaged edge metal or flashing, rooftop equipment, fallen limbs or debris, interior water intrusion, and affected exterior components. If emergency repairs are required to protect the building, document the original condition first and retain all photographs, invoices, and receipts related to the work.
Does my roofing contractor determine what my insurance will cover?
No. These are two separate roles. A commercial roofing contractor evaluates the roof, documents the damage and existing conditions, and explains what is required to repair or replace the system correctly. Your insurance company determines coverage based on your specific policy, endorsements, deductibles, and exclusions. Understanding this distinction helps set clear expectations throughout the claims process.
How does a manufacturer-backed warranty help after a storm?
Many manufacturer-backed systems require installation to a specific approved assembly, followed by a final manufacturer inspection before the roof is accepted for warranty. That process creates valuable third-party documentation showing how the roof was required to be installed—including fastener spacing, membrane and insulation attachment, and perimeter and corner enhancements—and that the completed system was inspected and accepted before the storm. This independent record is far stronger than relying solely on a contractor’s word that the roof was installed correctly.
Can storm repairs affect my existing roof warranty?
Yes. Storm damage does not automatically eliminate an existing manufacturer warranty, but the wrong repair can create warranty problems. Before anyone cuts, patches, alters, or replaces portions of a warranted system, confirm what the manufacturer requires. A repair that stops today’s leak may not comply with the manufacturer’s standards. Working with a commercial contractor familiar with your roofing system helps protect the warranty you already paid for.
Why should I keep a roof access log?
Commercial roofs are regularly accessed by HVAC technicians, electricians, plumbers, telecommunications contractors, and maintenance personnel. A simple log recording who accessed the roof, when, why, and what work was performed helps determine what happened and when if damage is later discovered. Combined with inspection reports, photographs, maintenance records, and manufacturer documentation, an access log builds a much clearer history of your roofing system.
How do I choose the right commercial roofing contractor after a storm?
Look beyond who can arrive first. Choose a contractor who regularly works with commercial roofing systems, understands manufacturer requirements, can perform manufacturer-approved repairs, maintains an established local presence, and will still be available after the storm work is finished. The goal is not simply to get through an insurance claim—it is to restore the roofing system correctly and protect your building for years afterward.
