Direct Answer
Yes. For most Florida commercial roofs, May and December are strong choices for twice-annual inspections. A May inspection gives the property team an opportunity to identify and correct vulnerabilities before the Atlantic hurricane season begins on June 1. A December inspection provides a post-season condition check after the main hurricane period and helps identify damage, drainage issues, or deferred maintenance before the next year.
NOAA states that the Atlantic hurricane season officially runs from June 1 through November 30, with peak activity around September 10 and most activity occurring from mid-August through mid-October. ([noaa.gov](https://www.noaa.gov/news-release/noaa-predicts-below-normal-2026-atlantic-hurricane-season?utm_source=chatgpt.com))
For that reason, a practical Florida commercial roofing schedule is one inspection in May and one in December, supplemented by inspections after significant storms, hurricanes, or other events that could have affected the roof.
Who This Applies To
This guidance is primarily for commercial property owners, property managers, facility managers, building engineers, developers, REITs, and portfolio managers responsible for commercial roofs in Florida.
Not for: Properties with unusually high debris exposure, recurring leaks, critical operations, severe roof deterioration, or known storm damage. These buildings may require more frequent inspections.
1. Why May Is a Good Time for the First Inspection
May is ideal for the pre-hurricane-season inspection. The purpose is to identify vulnerabilities while there is still time to address them before June 1.
The inspection should focus on:
- Roof membrane condition
- Open or deteriorated seams
- Flashing and penetrations
- Roof edges and perimeter securement
- Drains and scuppers
- Gutters and downspouts
- Overflow drainage
- Loose rooftop equipment or supports
- Previous repair areas
- Signs of ponding water
- Debris or objects that could damage the roof
- Conditions that could affect wind performance
NOAA recommends completing hurricane preparation before the official season begins rather than waiting until the season is underway. ([noaa.gov](https://www.noaa.gov/prepare-before-hurricane-season?utm_source=chatgpt.com))
2. Why December Is a Good Time for the Second Inspection
December works well as the post-hurricane-season inspection. By this point, the property has passed through the June-November hurricane season and the roof can be evaluated for damage or deterioration that may not have been immediately obvious.
The inspection can identify:
- Storm-related membrane damage
- Loose flashing or edge components
- Damaged coping or metalwork
- Blocked drains and scuppers
- New ponding areas
- Damaged rooftop equipment supports
- Failed temporary repairs
- New interior leak evidence
- Debris-related damage
- Conditions requiring repair before the next storm season
This also creates a useful baseline for planning the following year’s maintenance and capital expenditures.
3. Why You Should Not Wait Until September
September is historically close to the peak of Atlantic hurricane activity. NOAA identifies September 10 as the climatological peak, with most Atlantic activity occurring between mid-August and mid-October. ([nhc.noaa.gov](https://www.nhc.noaa.gov/climo/?utm_source=chatgpt.com))
That makes September a poor choice for the only pre-storm inspection. If a serious deficiency is discovered at that point, the property may have limited time to obtain materials, schedule qualified contractors, complete repairs, and address permitting or engineering requirements before another storm threatens the area.
The objective of the May inspection is therefore to find problems before the highest-risk portion of the season, not during it.
4. Recommended Florida Commercial Roof Inspection Calendar
| Time | Purpose | Typical Focus |
|---|---|---|
| May | Pre-hurricane-season inspection | Wind-related vulnerabilities, drainage, flashing, membrane, edges, penetrations and previous repairs |
| June–November | Event-based inspections | Inspect after significant storms, hurricanes or suspected damage |
| December | Post-hurricane-season inspection | Storm damage, recurring leaks, drainage, repairs and lifecycle condition |
| Any time | Problem-driven inspection | Active leaks, ponding, visible damage or other reported conditions |
5. Should the Inspection Be Exactly Six Months Apart?
No. The goal is to place the inspections at useful points in the roof’s annual risk cycle, not to maintain an exact 182-day interval.
For example, a property might schedule its inspections for early May and early December. Another property may choose late April and late November based on its maintenance contractor, operating schedule, or portfolio requirements.
The important consideration is having one inspection before hurricane season and another after the main storm season.
6. What If the Property Has High Hurricane Exposure?
Properties with significant hurricane exposure may benefit from more frequent inspections or additional targeted reviews.
Consider increasing inspection frequency when the building has:
- Recurring roof leaks
- An older roof
- Extensive previous repairs
- Large rooftop HVAC installations
- Solar equipment
- Complicated roof geometry
- Extensive penetrations
- Known drainage problems
- Recurring ponding water
- Critical business operations
- High-value equipment or inventory
- Previous storm damage
For these properties, quarterly inspections may be more appropriate than a simple twice-annual schedule.
7. Should You Inspect After a Hurricane?
Yes. A twice-annual schedule should not be treated as a substitute for post-storm inspections.
If a hurricane or significant windstorm affects the property, perform an additional inspection when conditions are safe. Look for membrane damage, displaced flashing, edge damage, debris impact, damaged rooftop equipment, drainage blockages, and new water intrusion.
A post-storm inspection is particularly important when the roof has experienced strong winds even if no interior leak has been reported. Some roof deficiencies may not become apparent until subsequent rainfall.
8. What Should Be Done During the May Inspection?
The May inspection should be more than a quick visual walkthrough. It should establish whether the roof is ready for the upcoming hurricane season.
At minimum, document:
- Roof-system condition
- Membrane and seam condition
- Flashing
- Perimeter and edge conditions
- Roof-to-wall interfaces
- Penetrations
- Drains and scuppers
- Emergency drainage
- Rooftop equipment
- Previous repair areas
- Ponding areas
- Loose debris
- Conditions affecting wind performance
Any deficiencies should be prioritized according to urgency rather than simply listed in a report.
9. What Should Be Done During the December Inspection?
The December inspection should concentrate on what changed during the storm season.
Compare current photographs and conditions against the May baseline. Look for new defects, recurring leaks, failed repairs, drainage problems, and deterioration that may have developed during the summer and fall.
This makes the two-inspection schedule more useful because the inspections create a year-over-year record rather than two unrelated visits.
10. How Does This Help With Maintenance and Capital Planning?
A consistent May/December inspection cycle provides useful information for deciding which roofs require immediate maintenance and which should enter a longer-term capital plan.
For each building, maintain:
- Inspection date
- Roof system and approximate age
- Roof area
- Condition rating
- Leak history
- Previous repairs
- Storm damage
- Drainage issues
- Warranty information
- Recommended repairs
- Estimated replacement timeframe
Over several years, this creates a valuable roof asset history that can support budgeting and portfolio-level maintenance decisions.
Bottom Line
For most Florida commercial roofs, May and December are practical months for twice-annual inspections. May provides a pre-hurricane-season opportunity to correct vulnerabilities before June 1, while December provides a post-season opportunity to identify storm damage and prepare the roof for the next maintenance cycle.
Because Atlantic hurricane activity peaks around September, waiting until September for the main inspection is generally less useful than completing the primary inspection in May. ([nhc.noaa.gov](https://www.nhc.noaa.gov/climo/?utm_source=chatgpt.com))
However, the schedule should be supplemented with post-storm inspections and additional inspections for older, complex, high-risk, or repeatedly leaking roofs.
