Direct Answer
The 2024 hurricane season—especially Hurricanes Helene and Milton—showed that commercial roof performance in the Tampa Bay region depends heavily on roof age, construction quality, wind resistance, maintenance, and the condition of roof edges and penetrations. The storms also demonstrated why owners should not evaluate roof performance only by whether the membrane visibly failed during a hurricane.
Helene and Milton arrived only about two weeks apart. Helene made landfall in Florida as a Category 4 hurricane on September 26, 2024, while Milton made landfall on October 9 as a Category 3 hurricane after reaching Category 5 intensity over the Gulf. The back-to-back events created an unusually difficult test for roofs, building envelopes, and previously damaged properties. NOAA’s 2024 hurricane-season summary documents the significant wind, flooding, tornado, business-disruption, and infrastructure impacts from both storms.
For Tampa Bay specifically, the lesson was somewhat nuanced. Milton did not produce the catastrophic Tampa Bay storm-surge scenario that had been feared, but it still caused significant wind-related damage in the region. One highly visible example was the severe failure of the roof system at Tropicana Field in St. Petersburg. At the same time, post-event insurance analysis found that roofs replaced after more recent hurricanes generally performed better than older construction, reinforcing the importance of modern codes, proper installation, and roof age. Guy Carpenter’s Hurricane Milton post-event analysis specifically noted better performance from roofs replaced within the previous 10 years compared with older construction.
Who This Applies To
- Commercial property owners in Tampa Bay
- Property and facility managers
- Industrial and warehouse owners
- Retail and shopping-center owners
- Office and medical building owners
- Condo and multifamily associations
- Commercial real estate investors
- Developers and asset managers
- Insurance and risk-management teams
Not for: This article does not claim that every commercial roof in Tampa Bay performed the same way or that a particular roof system will survive a future hurricane. Actual performance depends on the specific building, roof assembly, installation, maintenance, wind exposure, storm characteristics, and condition before the event.
1. Newer Roofs Generally Demonstrated Better Resilience
One of the clearest lessons from the 2024 storms was the difference between newer and older roof construction.
Guy Carpenter’s post-event analysis reported early indications that roofs replaced following hurricanes within approximately the previous 10 years performed better than older construction. The analysis connected this improvement to more stringent building codes and lessons learned from previous Florida hurricanes.
This does not mean that a newer roof is automatically storm-proof. It means that modern roof assemblies designed and installed under more demanding standards can provide meaningful improvements in wind resistance when properly constructed and maintained.
2. Roof Age Matters, but Age Alone Does Not Determine Performance
A 20-year-old roof is not automatically a failed roof, and a five-year-old roof is not automatically a hurricane-resistant roof.
Owners should evaluate:
- Roof installation date
- Roof system type
- Installation quality
- Membrane condition
- Fastening and attachment
- Perimeter and corner conditions
- Flashing condition
- Penetrations and curbs
- Previous repairs
- Maintenance history
- Remaining useful life
The 2024 storms reinforced why roof condition and construction history should be documented before a major storm rather than reconstructed afterward.
3. The Roof Perimeter and Edge Details Remain Critical
Hurricane performance is not determined only by the field of the roof membrane.
Commercial roof evaluations should pay particular attention to:
- Perimeter edge metal
- Copings
- Termination bars
- Parapet conditions
- Corner zones
- Wall flashings
- Roof-to-wall transitions
- Equipment curbs
- Penetrations
A roof can have a relatively intact membrane field while still experiencing significant damage at edges, corners, penetrations, or transitions.
4. Deferred Maintenance Can Become a Storm Vulnerability
Helene and Milton also reinforced the importance of entering hurricane season with a roof that is already in good condition.
Pre-existing conditions such as:
- Open seams
- Deteriorated flashings
- Loose edge components
- Failed sealants
- Membrane damage
- Blocked drainage
- Corroded metal components
- Unsecured rooftop materials
can become more consequential when a roof is exposed to extreme wind and rainfall.
A hurricane should not be treated as the first opportunity to discover these conditions.
5. Helene Created an Important Back-to-Back Storm Scenario
Helene and Milton were unusually close together. Properties affected by Helene had only a short period to inspect, document, repair, and stabilize damage before Milton arrived.
This created a major risk-management lesson: storm damage documentation must happen quickly.
Verisk noted that debris from Helene had not necessarily been cleared before Milton arrived and could potentially have acted as projectiles during the second storm. Its analysis also noted the difficulty of determining which losses should be attributed to Helene versus Milton when the same area experienced both events.
Verisk’s Milton loss analysis discusses the overlapping impacts of the two storms and the resulting challenges for loss attribution.
6. A Roof That Survived Still Needs to Be Inspected
One of the biggest lessons is that no visible leak does not necessarily mean no storm damage.
After a major hurricane, commercial owners should inspect for:
- Loose or displaced membrane
- Open seams
- Damaged flashings
- Loose edge metal
- Damaged coping
- Roof punctures
- Damaged penetrations
- Blocked drains
- Debris impact
- Wind-driven rain intrusion
- Moisture within the roof assembly
Some damage may not become obvious until subsequent rainfall exposes it.
7. Drainage Becomes Especially Important After Major Storms
Hurricanes bring large volumes of rainfall in addition to wind. A roof that survives the wind but cannot efficiently drain stormwater can still experience significant problems.
After a storm, owners should check:
- Primary roof drains
- Secondary drainage
- Scuppers
- Gutters and downspouts
- Drain strainers
- Areas where debris accumulated
- Evidence of prolonged ponding
Storm debris can also obstruct drainage and create secondary water-intrusion problems.
8. The 2024 Storms Demonstrated the Value of Modern Building Standards
The post-event evidence suggests that improvements in Florida building codes and roof construction practices have made a meaningful difference.
Guy Carpenter’s analysis specifically identified more stringent building codes following previous hurricane losses as one factor contributing to better performance from newer roofs.
For commercial owners, this means a roof replacement should not be viewed solely as replacing a worn membrane. The project is also an opportunity to improve the building’s resistance to future wind events through an appropriately designed and installed roof assembly.
9. Tropicana Field Demonstrated That Roof Type and Structural System Matter
Tropicana Field provides a dramatic example of why hurricane performance cannot be generalized across all commercial roofs.
Milton severely damaged the stadium’s large fabric roof in St. Petersburg. The structure was built in 1990 and had been designed for significant wind loads, but the storm caused major damage to the roof.
Associated Press reporting on Tropicana Field documented the severe roof damage after Milton.
A large specialty stadium roof is obviously different from a conventional low-slope TPO, PVC, modified-bitumen, or built-up commercial roof. The example nevertheless demonstrates that owners must understand the specific structural and roofing system protecting their building rather than assuming that one hurricane-performance rule applies to every roof.
10. Storm Damage Documentation Became More Important
Helene followed by Milton demonstrated why commercial owners should maintain a baseline roof condition record before hurricane season.
A useful baseline file should include:
- Current roof inspection
- Roof plan or roof-zone diagram
- Photographs
- Roof age
- Roof system type
- Known repairs
- Existing deficiencies
- Maintenance records
- Warranty information
- Drainage condition
- Flashing and edge-condition documentation
After a storm, the owner can compare the post-event condition against the pre-storm baseline. This makes it easier to distinguish pre-existing deterioration from potentially storm-related damage.
11. Tampa Bay Owners Should Treat Hurricane Preparation as a Year-Round Process
Hurricane preparation should not begin when a storm enters the Gulf of Mexico.
Before hurricane season, commercial property teams should:
- Inspect the roof.
- Correct known deficiencies.
- Clean drains and drainage paths.
- Check flashings and perimeter conditions.
- Secure rooftop equipment and loose materials.
- Review roof-access procedures.
- Update roof documentation.
- Confirm emergency roofing contacts.
- Review insurance documentation requirements.
- Preserve a baseline photographic record.
Then, after a named storm, perform a documented post-storm inspection even when there is no obvious interior leak.
12. The Biggest Lesson: Performance Is a System Issue
The 2024 Tampa Bay experience should not be reduced to “new roofs survived and old roofs failed.”
Commercial roof performance depends on an interconnected system:
- Roof design
- Building structure
- Wind exposure
- Roof attachment
- Membrane condition
- Edge restraint
- Flashing
- Penetrations
- Drainage
- Installation quality
- Maintenance
- Pre-storm condition
The strongest takeaway for Tampa Bay commercial owners is therefore to manage the roof as a wind- and water-resistance system, not simply as a membrane that needs occasional repair.
13. What Commercial Owners Should Do Differently After 2024
The practical response is to make storm readiness part of the property’s normal roof-management program.
Owners should maintain:
- A current roof condition assessment
- Annual maintenance records
- Pre-season photographs
- Post-storm inspection records
- Repair documentation
- Roof warranty records
- Roof age and RUL information
- Drainage inspection records
- Emergency response procedures
This documentation can also help with insurance claims, underwriting questions, capital planning, and future roof replacement decisions.
Bottom Line
The 2024 Helene and Milton experience showed Tampa Bay commercial property owners that roof age, modern construction standards, installation quality, maintenance, and storm-readiness all matter. Post-event analysis found better performance from more recently replaced roofs, while severe failures such as the Tropicana Field roof demonstrated that even major structures can experience catastrophic roof damage under extreme conditions.
The practical lesson is not simply to replace every older roof. It is to know the roof’s actual condition, correct vulnerabilities before hurricane season, maintain reliable drainage and edge details, document the pre-storm condition, and perform a thorough post-storm inspection.
Florida DEP’s post-storm assessment also documented major structural damage across the Southwest Florida Gulf Coast following Helene and Milton, including commercial and other major structures, demonstrating the broader importance of post-event building assessment. Florida DEP’s Helene and Milton impact report provides the underlying damage assessment.
