You walk into your commercial property after a severe thunderstorm. Branches litter the parking lot, and tenants are reporting damp ceiling tiles. You look up at the sky and assume your roof survived the storm.
But has it?
Property owners often overlook hail damage on commercial roofs. Unlike other types of storm damage, hail can create micro-fractures, membrane bruising, and granule loss that don’t appear immediately. However, once water finds its way into the building, repair costs can rise quickly, and you may have less time to file an insurance claim.
With over 27 years of commercial roofing experience across 11 markets in Tornado Alley and the Gulf Coast corridor, Weather Contracting has seen firsthand how hail affects commercial roofs—and what property owners frequently miss.
Why Hail Damage Is So Easy to Overlook on Commercial Roofs
Commercial roofs, especially flat and low-slope systems such as TPO, EPDM, PVC, and modified bitumen, can conceal storm damage.
The roof looks fine from the ground: Flat and low-slope roofs are difficult to inspect properly without walking the roof. As a result, property owners may assume there’s no damage simply because they can’t see any from the ground.
Membrane damage isn’t always obvious: Hail can create micro-punctures and stress fractures that are virtually invisible. Even so, these small openings can eventually allow water to enter the roofing system.
Damage may not leak right away: A compromised membrane might not begin leaking for months. Therefore, the absence of an immediate leak doesn’t necessarily mean the roof escaped damage.
Insulation can absorb water invisibly: Water can penetrate the insulation beneath the membrane and damage the system from within. Meanwhile, the roof may continue to look normal from the outside.
Fast inspections may miss key issues: Some areas of a roof can sustain more damage than others. For this reason, a thorough inspection should evaluate the entire roofing system rather than focusing only on obvious impact areas.
Property owners may think their roof is intact until they discover that a relatively simple issue has developed into a much larger and more expensive problem.
What Hail Damage Looks Like on Different Commercial Roofing Materials
Each type of commercial roofing material reacts differently to hail. Therefore, inspectors look for different warning signs depending on the roof system.
TPO Roofing
Look for round indentations, dimples around impact sites, micro-tears near seams, and discoloration where hail has compressed the membrane’s top layer.
EPDM Roofing
Look for puncture marks, hairline cracks spreading from impact areas, separation along seams, and dark spots where hail has compressed the membrane against the substrate.
PVC Roofing
Look for fractures, weakened heat-welded seams, and cracks around flashings and penetrations. In particular, vulnerable areas around roof penetrations may require closer inspection after a severe storm.
Metal Roofing
Common signs include dents, coating chips that expose bare metal, panel distortion that interferes with proper drainage, and loose fasteners. Although some dents may appear cosmetic, other impacts can affect the roof’s long-term performance.
Modified Bitumen and Built-Up Roofing (BUR)
Look for granule loss that exposes the bitumen below, cracks along seams and flashings, and blisters caused by trapped moisture. Over time, these problems can leave the roofing system more vulnerable to water intrusion and further deterioration.
The Cost of Delaying Hail Damage Repairs
Hail damage doesn’t always create an immediate emergency. However, delaying an inspection or necessary repairs can allow a small problem to spread through the roofing system.
Week 1: Hail damages the membrane, but you may not see any visible leaks.
Months 1–3: Rain begins penetrating damaged areas and soaking the insulation below the membrane. Because the moisture remains beneath the roof surface, you may still see few warning signs inside the building.
Months 3–6: Wet insulation starts losing R-value, which can increase your energy bills. In addition, trapped moisture can contribute to blistering and delamination. Water stains may also begin appearing indoors.
Months 6–12: Leaks can begin damaging ceilings, walls, electrical systems, equipment, and inventory. At this point, a simple spot repair may no longer solve the problem.
Month 12 and beyond: What began as a small puncture can develop into a larger roofing-system issue. Additionally, your insurer may question whether the damage resulted directly from the storm or from neglected maintenance over time.
Swift action can help prevent a minor hail issue from becoming a major roofing problem.
Why You Should Get a Professional Hail Damage Inspection
A professional commercial roof inspection gives you three important advantages:
1. Trained Evaluation
Weather Contracting inspectors examine seam integrity, membrane condition, insulation moisture, flashings, and penetrations. These areas can conceal damage that property owners may not notice during a visual inspection from the ground.
Additionally, a trained inspector can distinguish between normal wear and potential storm-related damage, giving you a clearer picture of your roof’s condition.
2. Photos and a Report
Weather Contracting provides photos and a report that document the roof’s condition and any identified damage. This documentation can support an insurance claim and help connect the damage to the storm event.
Furthermore, detailed records give property owners a useful baseline for future maintenance, repairs, and roof-management decisions.
3. Repair Prioritization
Not every hail impact requires immediate repair. Therefore, an inspection can help distinguish cosmetic issues from damage that could compromise the roof’s function.
With this information, you can prioritize urgent repairs while planning appropriately for less critical maintenance.
How Weather Contracting’s Insurance Claim Process Works
Once an inspection confirms hail damage, Weather Contracting can assist with the insurance process in several ways:
Documentation of storm damage: Weather Contracting conducts thorough assessments and provides photos that document identified damage.
On-site coordination with the insurance adjuster: Our team works directly with the insurance adjuster during the inspection process to help identify the full extent of the damage.
Review of the scope of work: We review estimates to help ensure they account for necessary repairs, including damaged or water-soaked insulation.
Executing repairs: After approval, our crews complete the necessary work, whether the project calls for targeted repairs, section replacements, or restoration of the entire roof system.
By supporting commercial property owners throughout the insurance process, Weather Contracting helps protect both the roofing system and the property owner’s investment.
The Weather Watch Program: Monitoring and Asset Management After Hail Season
Weather Contracting’s Weather Watch program doesn’t wait for leaks to happen. Instead, it actively monitors your roof and helps manage your roofing assets over time.
The program includes scheduled inspections before and after storm season, post-hail storm inspections, long-term condition reporting, and budget planning for roof maintenance, repairs, and replacement.
As a result, property owners gain a clearer understanding of their roof’s condition before small issues become expensive surprises.
For owners managing a portfolio of properties in high-risk storm areas, Weather Watch provides greater visibility across roofing assets. In addition, the program can help you proactively plan maintenance schedules, repair priorities, and future capital expenses.
What to Do After a Hail Storm: Your Immediate Checklist
After a significant hail storm, taking a few simple steps can help you identify problems early and document potential damage.
Document the storm: Note the date, time, and approximate hail size if possible. You can also save photos or videos of hail around the property.
Look for signs inside: Check for water stains, wet ceiling tiles, musty odors, unusual humidity, or other signs of moisture intrusion.
Schedule a roof inspection: Have a commercial roofing professional inspect the roof even if you don’t see obvious damage. Because many forms of hail damage remain hidden, an inspection can identify issues before leaks develop.
Don’t delay: Your policy may include a deadline for filing a hail damage insurance claim. Furthermore, waiting too long can make it more difficult to establish a clear connection between the roof damage and a specific storm event.
Inquire about temporary protection: If the inspection confirms damage, ask about temporary patching or emergency shrink-wrap seals to help prevent additional water intrusion while you determine the next steps.
FAQ
How big does hail have to be to damage a commercial roof?
Even hail as small as 1 inch can damage an older or stressed roof membrane. Meanwhile, larger hail can cause significant damage even to newer roofing systems.
However, hail size isn’t the only factor. A roof’s age, material, installation, existing condition, and exposure all play a role in how well it withstands a hail storm.
Will my insurance company pay for hail damage to my commercial roof?
Most commercial property policies provide some form of coverage for hail damage, but coverage depends on the specific policy, deductible, exclusions, and documentation requirements.
While Weather Contracting can’t guarantee the outcome of an insurance claim, our team can provide documentation, coordinate with the insurance adjuster, and review the scope of work.
How long do I have to file an insurance claim for hail damage?
Insurance companies have different time limits based on policy terms and applicable state laws. For example, some policies may require property owners to file claims within 12 months, while others may have shorter timeframes.
For this reason, scheduling an inspection within a few days of a significant hail event can help ensure timely documentation and reduce uncertainty about when the damage occurred.
Can a hail-damaged commercial roof be repaired, or does it need to be replaced?
The answer depends on the extent and location of the damage, as well as the roof’s age and overall condition.
For example, hail damage limited to one portion of the roof may only require targeted repairs. In contrast, widespread damage or damage to a roof nearing the end of its service life may justify a partial or full roof replacement.
In some cases, applying an elastomeric coating can also extend the roof’s service life and delay replacement. However, a professional inspection can help determine which approach makes the most sense for the specific roofing system.
