Direct Answer
When an underwriting inspection flags deteriorated flashings on a commercial roof, the property owner should document the affected areas, determine whether the deterioration is localized or widespread, identify the cause and potential water-intrusion risk, and have a qualified roofing professional recommend the appropriate corrective action. The owner should then complete the required repair or restoration, retain before-and-after documentation, and provide the insurance carrier or broker with evidence that the underwriting concern has been addressed.
Deteriorated flashing does not automatically mean the entire roof must be replaced. The appropriate response depends on the type and extent of deterioration, the roof system, roof age, remaining useful life (RUL), leak history, surrounding membrane condition, and the carrier’s specific underwriting requirements.
Citizens’ current 2026 commercial guidance requires roofs to be in good condition and allows roof-condition documentation from a licensed general or roofing contractor, including use of its Commercial Roof Condition Inspection Form. Citizens also states that roof condition is evaluated by an appropriately licensed inspector and that deficiencies can affect underwriting decisions. :chatgpt-content-reference{index=”0″}
Who This Applies To
- Commercial property owners
- Property managers and facility managers
- Commercial real estate investors
- Developers and asset managers
- Insurance agents and brokers
- Owners responding to underwriting or loss-control findings
- Owners preparing for commercial insurance renewal
Not for: This is general insurance-readiness and commercial roofing guidance. Specific underwriting requirements, coverage decisions, and repair specifications should be confirmed with the carrier, insurance professional, and qualified roofing professional.
1. Obtain the Complete Underwriting Finding
Start with the complete inspection report. Do not rely only on a notation such as “deteriorated flashing.”
Determine:
- Where the deteriorated flashing is located
- Which flashing components are affected
- Whether the deterioration is minor, moderate, or severe
- Whether the flashing is loose, cracked, corroded, split, separated, or otherwise deficient
- Whether the condition affects roof penetrations, walls, curbs, edges, drains, or other transitions
- Whether photographs were included
- Whether active or historical leaks were identified
- Whether the inspector identified additional roof deficiencies
- Whether underwriting established a deadline for correction
A precise description is important because “flashing deterioration” can describe anything from a localized repairable condition to widespread failure of critical roof-to-wall or penetration details.
2. Determine Whether Water Is Entering the Building
Flashing is particularly important at transitions and penetrations where the roof system has to remain watertight. If deteriorated flashing has created an opening, water may reach the roof assembly or interior of the building.
Check for:
- Active leaks
- Interior staining
- Wet insulation
- Water around penetrations
- Repeated leaks in the same location
- Evidence of previous temporary repairs
- Moisture around wall or curb transitions
If the flashing deficiency is actively allowing water intrusion, address the immediate exposure while the permanent corrective work is being developed.
3. Determine Whether the Deterioration Is Localized or Widespread
| Finding | Potential Significance | Typical Response |
|---|---|---|
| One isolated deteriorated flashing | Potential localized deficiency | Repair and document |
| Several deficient flashings in one roof section | Possible localized system deterioration | Detailed roof evaluation |
| Widespread flashing deterioration | Potential systemic aging or installation issue | Evaluate restoration or replacement |
| Flashing deterioration with active leaks | Immediate water-intrusion exposure | Prompt corrective action |
| Flashing deterioration plus membrane damage | Potential broader roof-system failure | Comprehensive condition assessment |
The goal is to determine whether the underwriting finding represents one repairable defect or evidence of a broader roof-condition problem.
4. Identify the Cause of the Deterioration
Ask why the flashing deteriorated before selecting a repair.
Possible causes include:
- Normal aging
- Weather exposure
- Corrosion
- Improper original installation
- Incompatible materials
- Movement between building components
- Improper previous repairs
- Damage caused by rooftop trades
- Repeated maintenance activity
- Long-term water exposure
If the underlying cause is not corrected, a replacement flashing may deteriorate again or continue to permit water intrusion.
5. Inspect the Adjacent Roof Components
Do not limit the evaluation to the exact flashing identified by underwriting.
The surrounding area should also be examined for:
- Membrane deterioration
- Open seams
- Loose or damaged counterflashing
- Failed sealants
- Damaged penetration details
- Cracked or deteriorated curbs
- Drainage problems
- Previous repair patches
- Additional deteriorated flashing
This broader review helps establish whether the flashing is an isolated defect or part of a larger roof-system condition.
6. Evaluate Roof Age and Remaining Useful Life
Underwriting treatment can differ depending on the overall condition and remaining life of the roof.
Review:
- Original roof installation date
- Date of the most recent roof replacement
- Roof system type
- Previous restoration or coating work
- Repair history
- Previous inspection reports
- Current estimated RUL
Citizens states that its underwriting review considers roof condition and that a roof-condition inspection can be used to establish remaining useful life. Citizens also reserves the final decision regarding overall roof insurability even when an inspection provides an RUL assessment. :chatgpt-content-reference{index=”1″}
7. Determine Whether Repair, Restoration, or Replacement Is Appropriate
A deteriorated flashing does not automatically justify a complete roof replacement.
A qualified roofing professional may recommend:
- Localized flashing repair
- Replacement of the affected flashing
- Replacement of associated sealants or termination components
- Repair of the surrounding membrane
- Restoration of a roof section
- Broader roof restoration
- Complete roof replacement when deterioration is widespread or the roof is near the end of its useful life
The decision should consider the actual roof condition rather than simply the age of the roof or the existence of one underwriting observation.
8. Get the Carrier’s Requirements in Writing
Before completing major corrective work, ask the insurance agent or broker to confirm what underwriting needs to close the finding.
Questions should include:
- Is localized flashing replacement acceptable?
- Does the carrier require additional roof areas to be inspected?
- Is a post-repair inspection required?
- Does underwriting require a specific roof-condition form?
- Are photographs required before and after repair?
- Must a Florida-licensed roofing or general contractor certify the repair?
- Is an updated RUL statement required?
- What is the deadline for correcting the condition?
Citizens’ 2026 commercial documentation specifically identifies roof-condition certification by a licensed general or roofing contractor and the Commercial Roof Condition Inspection Form as documentation that may be used to document roof condition and updates. :chatgpt-content-reference{index=”2″}
9. Complete the Corrective Work
Once the scope is established, complete the work using a qualified commercial roofing professional.
The scope should clearly identify:
- The affected roof areas
- The deteriorated flashing components
- The materials being replaced or repaired
- How the new flashing will integrate with the existing roof system
- Any membrane or sealant work required
- Any related deficiencies discovered during the repair
Do not simply cover visible deterioration with a temporary sealant if the underlying flashing has failed and the carrier is expecting permanent corrective action.
10. Document the Work Before and After Repair
Create a complete record of the corrective action.
Keep:
- Original underwriting inspection
- Before photographs
- Detailed repair proposal
- Repair scope
- Contractor invoice
- Paid receipt
- Material documentation where relevant
- After photographs
- Inspection or completion report
- Permit documentation where applicable
- Warranty information
Citizens’ roof-inspection guidance requires photographs of roof areas and deficiencies and calls for detailed descriptions when hazards, deficiencies, or roofs not in good working order are identified. :chatgpt-content-reference{index=”3″}
11. Arrange a Follow-Up Inspection When Required
If underwriting requires confirmation that the deficiency has been corrected, obtain the appropriate follow-up inspection.
The follow-up documentation should establish:
- What was originally identified
- What corrective work was performed
- That the work is complete
- That the affected flashing is functioning as intended
- Whether additional related deficiencies remain
- Photographic evidence of the completed work
Citizens states that an appropriately licensed inspector is responsible for evaluating overall roof condition and identifying deficiencies. :chatgpt-content-reference{index=”4″}
12. Submit a Complete Underwriting Package
Give the insurance agent or broker a complete package rather than sending only a contractor invoice.
A useful package can include:
- Original underwriting inspection
- Roof condition assessment
- Photographs of the deteriorated flashing
- Cause and extent of the deficiency
- Repair scope
- Before-and-after photographs
- Paid invoice
- Permit or completion documentation where applicable
- Updated inspection report
- RUL information if requested
Ask the agent or broker to confirm that underwriting has received the documentation and determine whether any additional action is required.
13. What If the Flashing Problem Is Widespread?
If multiple areas show deteriorated flashing, do not treat each location as an independent repair without evaluating the roof as a whole.
Widespread deterioration may indicate:
- An aging roof system
- Systemic installation problems
- Repeated water intrusion
- Material compatibility issues
- Long-term exposure
- A roof approaching the end of its useful life
In that situation, a broader roof condition assessment may be more appropriate than completing a series of isolated repairs.
Citizens has stated that validation of roof condition can identify buildings with ineligible roof conditions and can lead to underwriting action or become the impetus for roof replacement and a return to eligibility. :chatgpt-content-reference{index=”5″}
14. Be Careful With Coatings as a Solution
A coating may be appropriate as part of a professionally designed restoration system, but it should not automatically be presented as equivalent to replacement of deteriorated flashing or a new roof.
Citizens states that when coatings or sealants are used to repair or extend a roof’s useful life, underwriting still reviews the original roof’s age and condition. :chatgpt-content-reference{index=”6″}
Therefore, if the underwriting finding specifically concerns failed or deteriorated flashing, document how the proposed restoration addresses that actual deficiency.
15. Keep the Corrective-Action Record for Future Renewals
Once the underwriting issue has been resolved, keep the entire record in the property’s permanent roof file.
Maintain:
- Underwriting inspection
- Photos
- Contractor assessment
- Repair scope
- Invoices and receipts
- Permits where applicable
- Follow-up inspection
- Warranty documentation
- Carrier correspondence
- Updated roof-condition information
This gives the owner evidence of what was found, what was corrected, and the roof’s documented condition when the work was completed.
Bottom Line
When an underwriting inspection flags deteriorated flashings, do not ignore the finding and do not automatically assume that the entire roof needs replacement. First establish the location, extent, cause, and water-intrusion risk. Then evaluate the surrounding roof system, roof age, RUL, and repair history.
Obtain the carrier’s requirements in writing, have the appropriate flashing repairs or restoration completed, document the work thoroughly, and provide the evidence to underwriting through the insurance agent or broker. For Citizens commercial risks, current guidance confirms that roof condition and deficiencies are important underwriting considerations and that licensed roofing or general contractors can provide roof-condition documentation. :chatgpt-content-reference{index=”7″}
