Direct Answer
Commercial owners in Volusia and Flagler Counties should prepare their roofs for both hurricane and coastal winter-storm exposure by treating roof condition, drainage, rooftop equipment, loose materials, access, documentation, and emergency response as one year-round program.
Volusia County specifically identifies hurricanes, tropical storms, nor’easters, and significant rain events as hazards for the county. Volusia also recommends inspecting roofs and drainage systems before storms. Flagler County similarly identifies hurricanes, tropical storms, storm surge, flooding, and severe weather as hazards and provides business-preparedness resources for property owners. :chatgpt-content-reference{index=”0″}
The most effective approach is to inspect and correct deficiencies before a storm is approaching, then perform a documented pre-storm check when a significant event is forecast. Owners should pay particular attention to membrane and flashing condition, roof drains, scuppers, edge metal, penetrations, rooftop equipment, loose objects, access points, and areas previously repaired.
Who This Applies To
- Commercial property owners in Volusia County
- Commercial property owners in Flagler County
- Property and facility managers
- Retail, office, industrial and warehouse owners
- Multifamily and mixed-use property owners
- HOAs and associations responsible for community buildings
- Developers and commercial real estate investors
- Owners preparing for insurance renewal or storm season
Not for: This is general commercial roofing and storm-preparedness guidance. Specific structural, engineering, insurance, evacuation, permitting, and emergency requirements should be confirmed with the applicable authority and qualified professional.
1. Start With a Professional Roof Condition Inspection
Do not wait until a hurricane or major coastal storm is forecast to discover roof deficiencies.
Before storm season, have the roof evaluated for:
- Open or deteriorated seams
- Membrane damage
- Deteriorated flashings
- Loose edge metal
- Damaged coping
- Loose or deteriorated fasteners
- Roof penetrations
- Pipe flashings
- Equipment curbs
- Previous repair areas
- Signs of water intrusion
- Drainage deficiencies
Volusia County recommends having a licensed professional check the roof rather than attempting a potentially dangerous roof inspection yourself. :chatgpt-content-reference{index=”1″}
A commercial roof inspection should produce a documented baseline so the owner knows the roof’s condition before a storm occurs.
2. Inspect and Clear the Drainage System
Heavy rainfall can turn a relatively small drainage problem into a major roof problem.
Inspect:
- Primary roof drains
- Secondary or emergency drainage
- Scuppers
- Gutters
- Downspouts
- Drain strainers
- Drain bowls
- Roof valleys and low areas
- Discharge locations
Remove leaves, branches, trash, construction debris, vegetation, and other obstructions.
Historical NOAA/FEMA commercial-building hurricane guidance specifically emphasizes checking roof drains before a hurricane because clogged drains can contribute to accumulated water and building damage. :chatgpt-content-reference{index=”2″}
3. Look for Ponding and Slow Drainage
Do not simply confirm that a drain is visible. Determine whether water actually has a clear path off the roof.
Look for:
- Persistent ponding
- Water stains or sediment rings
- Algae or biological growth
- Membrane deterioration in low areas
- Repeated leaks below drainage locations
- Damaged or blocked drains
- Water accumulating around rooftop equipment
If drainage problems are persistent, determine whether the cause is maintenance-related or whether there is a broader roof-slope, drainage, membrane, or structural issue requiring professional evaluation.
4. Inspect Flashings and Penetrations
Roof penetrations and transitions deserve special attention before a major storm.
Check:
- HVAC curbs
- Pipe penetrations
- Exhaust fans
- Skylights
- Roof hatches
- Parapet transitions
- Wall flashings
- Expansion joints
- Equipment supports
Look for cracked sealants, loose components, deteriorated metal, membrane separation, open seams, and previous temporary repairs.
A roof that appears acceptable from ground level can still have vulnerable penetration details that become significant during high winds and driving rain.
5. Check Roof Edges and Perimeter Details
For hurricane exposure, the roof perimeter deserves particular attention.
Inspect:
- Edge metal
- Metal coping
- Parapet caps
- Termination bars
- Fasteners
- Perimeter membrane attachment
- Corner conditions
- Areas with previous wind damage
NOAA notes that hurricane-force winds can cause significant building damage and that roofing materials and other loose objects can become windborne debris. :chatgpt-content-reference{index=”3″}
Any loose roofing component should be addressed before a storm rather than waiting for high winds to expose the deficiency.
6. Secure Rooftop Equipment and Loose Materials
Commercial roofs often contain equipment and materials that can create additional storm exposure.
Review:
- HVAC equipment
- Condensing units
- Electrical equipment
- Solar equipment
- Satellite or communications equipment
- Temporary materials
- Tools
- Construction materials
- Loose panels or covers
Any rooftop item that is not permanently secured should be evaluated before the storm.
Flagler County’s preparedness guidance specifically advises property owners to secure property and address hazards before severe weather, while its business-preparedness resources direct businesses toward FEMA planning resources. :chatgpt-content-reference{index=”4″}
7. Review Previous Roof Repairs
Pay particular attention to areas that have already experienced problems.
Review:
- Previous leak repairs
- Storm repairs
- Membrane patches
- Flashing repairs
- Temporary tarps
- Previous insurance claims
- Prior inspection findings
A recurring leak or previously damaged roof section deserves additional attention before a major storm because a new event can expose an already weakened area.
8. Prepare the Roof for Both Wind and Water
Hurricane preparation should not focus exclusively on wind.
Commercial roofs in Volusia and Flagler can face a combination of:
- High winds
- Wind-driven rain
- Heavy rainfall
- Storm surge
- Coastal flooding
- Windborne debris
- Extended power outages
Volusia County’s emergency-management guidance specifically identifies storm surge and flooding as separate considerations from evacuation zones, while Flagler County lists storm surge and flooding among its local hazards. :chatgpt-content-reference{index=”5″}
That means roof preparation should be coordinated with the property’s broader flood, drainage, emergency-power, access, and business-continuity planning.
9. Review Insurance and Roof Documentation Before Storm Season
Do not wait until after damage occurs to discover that important roof records are missing.
Maintain:
- Roof installation date
- Roof system information
- Inspection reports
- Repair records
- Maintenance records
- Roof warranties
- Before-storm photographs
- Prior storm-damage documentation
- Insurance information
- Contractor contact information
Flagler County recommends reviewing insurance coverage and documenting business property, while its post-disaster guidance recommends documenting damage with photographs and videos before cleanup or repairs. :chatgpt-content-reference{index=”6″}
For commercial insurance, also confirm with the broker whether the policy contains specific roof, wind, named-storm, flood, debris-removal, or reporting requirements.
10. Establish a Pre-Storm Roof Checklist
When a significant storm is approaching, use a documented checklist rather than relying on memory.
| Area | Pre-Storm Action |
|---|---|
| Roof surface | Check for visible damage, loose materials and debris |
| Drains | Clear and verify drainage paths |
| Scuppers/gutters | Clear obstructions |
| Flashings | Check visible deficiencies |
| Roof edges | Check loose or damaged perimeter components |
| Equipment | Secure or protect rooftop equipment as appropriate |
| Loose materials | Remove or secure potential windborne debris |
| Access | Restrict unnecessary roof access |
| Documentation | Capture pre-storm photographs |
| Emergency contacts | Confirm roofing, restoration and management contacts |
Do not send personnel onto the roof once conditions have become dangerous. NOAA advises taking protective action when a storm threatens and following official warnings and instructions. :chatgpt-content-reference{index=”7″}
11. Do Not Perform Last-Minute Major Roof Work Without Proper Planning
If the roof requires substantial repairs, address them well before hurricane season whenever possible.
Major work can involve:
- Roof replacement
- Large membrane repairs
- Flashing replacement
- Drainage modifications
- Edge-metal replacement
- Equipment relocation
- Structural reinforcement
Trying to complete major roofing work immediately before a storm can create additional scheduling, material, permitting, and quality-control risks.
The Florida Building Commission maintains the current 2026 Florida Building Code development and roofing resources. Applicable permitting and code requirements should be verified with the relevant building department for the property. :chatgpt-content-reference{index=”8″}
12. Know When to Bring in a Roofing Professional
Professional evaluation is especially appropriate when the roof has:
- Recurring leaks
- Widespread deterioration
- Loose or damaged edge details
- Open seams
- Deteriorated flashings
- Persistent ponding
- Significant previous storm damage
- Uncertain remaining useful life
- Insurance-related roof concerns
For insurance-related roof documentation, Citizens states that roof-condition documentation for commercial risks can include certification from a licensed general or roofing contractor, a comparable roofing report, or its Commercial Roof Condition Inspection Form, depending on the risk. :chatgpt-content-reference{index=”9″}
13. Have a Post-Storm Inspection Plan
Preparation does not end when the storm passes.
After conditions are safe, inspect and document:
- Membrane damage
- Missing or displaced roofing materials
- Open seams
- Flashing damage
- Edge-metal damage
- Roof penetrations
- Drainage blockage
- Standing water
- Debris impact
- Interior leaks
Do not disturb potentially relevant evidence before photographing the condition unless immediate action is necessary to prevent additional damage or protect people.
Flagler County specifically advises property owners to document damage with photographs and videos before cleanup or repairs and to keep detailed records of repair expenses. :chatgpt-content-reference{index=”10″}
14. Separate Storm Damage From Pre-Existing Conditions
A strong pre-storm documentation program makes it easier to distinguish new storm damage from conditions that existed beforehand.
For example, if a roof was photographed before a storm and the photographs show an intact flashing detail, a post-storm photograph showing that flashing displaced or damaged provides a much clearer record than a photograph taken for the first time after the event.
This is particularly useful for:
- Insurance claims
- Warranty discussions
- Contractor investigations
- Roof-condition reporting
- Capital planning
- Future underwriting
15. Build a Year-Round Commercial Roof Program
The best storm-preparation strategy is not a once-a-year inspection. It is a year-round roof management program.
A practical program includes:
- Routine roof inspections
- Drain and drainage maintenance
- Prompt leak investigation
- Documented repairs
- Pre-hurricane inspection
- Pre-major-storm preparation
- Post-storm inspection
- Updated roof photographs
- Current warranty records
- Insurance documentation
- Capital planning for aging roof systems
This approach reduces the likelihood that an easily correctable roof deficiency becomes a major storm-related problem.
Bottom Line
Commercial owners in Volusia and Flagler Counties should prepare roofs for hurricane and nor’easter exposure by inspecting the roof before storm season, correcting known deficiencies, clearing and testing drainage, checking flashings and penetrations, securing rooftop equipment and loose materials, documenting the roof’s pre-storm condition, and maintaining a clear emergency-response plan.
The key is to prepare for both wind and water. Volusia County explicitly identifies nor’easters and significant rain events in addition to hurricanes and tropical storms, while Flagler County identifies hurricanes, storm surge, flooding and other severe-weather hazards. :chatgpt-content-reference{index=”11″}
Owners should also maintain a documented roof history so that after a storm they can distinguish pre-existing conditions from new damage and provide insurers, contractors, and other stakeholders with reliable evidence.
