Direct Answer
A wind mitigation inspection for commercial roofs helps document the building features designed to resist hurricane-force winds and reduce wind-related damage. For commercial property owners in Florida, this inspection can help identify roof-system vulnerabilities, verify qualifying wind-resistant features, support insurance underwriting, and potentially establish eligibility for applicable insurance mitigation credits.
During the inspection, a qualified professional may review roof covering materials, roof-to-wall connections, roof-deck attachment, roof geometry, opening protection, and other applicable wind-resistance features. The inspection findings can help property owners understand how their building is constructed, identify opportunities to improve wind resistance, and assemble documentation requested by their insurance carrier.
However, a wind mitigation inspection is not the same as a comprehensive roof condition assessment. It does not automatically certify that the roof is leak-free, structurally sound, or free of deterioration. Owners should confirm which inspection form applies to their building type and insurance policy before scheduling the inspection.
Who This Applies To
- Commercial property owners
- Property and facility managers
- Commercial real estate investors
- Condominium associations and board members
- Commercial building developers
- Insurance agents and brokers
- Owners preparing for insurance renewal
- Owners evaluating hurricane-resistance improvements
Not for: This guide does not replace a structural engineering evaluation, a comprehensive roof condition assessment, a building-code inspection, or the insurer’s specific underwriting requirements.
1. Understand What a Wind Mitigation Inspection Evaluates
A wind mitigation inspection examines qualifying features that may help a building resist wind damage during hurricanes and severe storms.
Depending on the building type and applicable inspection requirements, the evaluation may cover:
- Roof covering: The type of roof covering and documentation establishing its installation or replacement history.
- Roof-deck attachment: How the roof deck is fastened to the supporting structure.
- Roof-to-wall connections: How the roof framing is connected to the building walls.
- Roof geometry: The shape and configuration of the roof, where applicable to the inspection criteria.
- Opening protection: Qualifying protection for windows, doors, skylights, and other openings where relevant.
- Wind-resistant features: Other qualifying construction or protective features specified by the applicable inspection form.
The precise requirements depend on the building classification and the form accepted by the insurer. Not every feature used in residential wind mitigation inspections applies identically to every commercial building.
2. Why Wind Mitigation Inspections Matter for Commercial Roofs
Wind mitigation inspections are valuable because they help owners document construction features that may influence wind performance and insurance underwriting.
Key benefits include:
- Identifying documented wind-resistant construction features.
- Helping owners understand potential roof-system vulnerabilities.
- Providing supporting evidence for insurance underwriting.
- Helping establish eligibility for applicable mitigation credits when the insurer’s requirements are met.
- Supporting informed decisions about future roof improvements.
- Creating a record of qualifying features for future insurance reviews.
Florida’s Citizens Property Insurance Corporation explains that wind mitigation inspections document qualifying protective features and may help eligible policyholders receive insurance premium discounts. Eligibility and savings depend on the applicable policy, inspection results, documentation, and insurer approval.

3. Understand the Difference Between Wind Mitigation and Roof Condition Inspections
These inspections serve different purposes. A building may need one or both, depending on its condition and insurance requirements.
| Inspection Type | Primary Purpose | What It Helps Establish |
|---|---|---|
| Wind mitigation inspection | Document qualifying wind-resistant construction features | Whether applicable mitigation features can be verified for insurance consideration |
| Roof condition inspection | Evaluate the current condition of the roof | Visible deficiencies, deterioration, and the need for corrective work |
| Comprehensive roof assessment | Evaluate roof condition, deficiencies, and maintenance or capital needs | Recommended repairs, restoration options, and longer-term planning considerations |
| Structural engineering evaluation | Address specific structural concerns | Engineering findings within the scope of the professional’s engagement |
A wind mitigation inspection should not be used as a substitute for a roof condition assessment when the building has leaks, deteriorated membrane, damaged flashing, or other roofing deficiencies.

4. Confirm Which Inspection Form Applies to the Building
One of the most important steps is identifying the correct form before scheduling the inspection.
Citizens identifies different wind mitigation forms for different building classifications, including:
- Uniform Mitigation Verification Inspection Form (OIR-B1-1802): Used for specified residential building types and certain residential condominium or apartment properties.
- Building Type II and III Mitigation Inspection Form (MIT-BT II and III): Used for specified residential condominium or commercial residential applicants seeking mitigation credits in buildings with four or more stories.
- Commercial Windstorm Protective Device Proof of Compliance (WPD-1C): Used to document qualifying opening protection for commercial nonresidential buildings.
These forms are not interchangeable. Confirm the appropriate form with the insurance agent or carrier based on the building’s classification and the requested coverage.

5. Gather Roof and Construction Documentation Before the Inspection
Preparing the relevant records can make it easier for the inspector to verify qualifying construction features.
Depending on the building and inspection requirements, gather:
- Roof installation or replacement permits.
- Paid roofing contracts and invoices.
- Roof system specifications.
- Manufacturer product approvals and installation documentation.
- Construction plans or relevant structural details.
- Photographs of documented roof components.
- Records of roof replacement or wind-resistance improvements.
- Previous mitigation inspection reports.
- Available documentation for protective devices and openings.
Some wind-resistance features cannot be confirmed through a surface-level roof inspection alone. Additional records, access to concealed components, or other verification may be necessary.

6. Hire an Appropriately Qualified Inspector
Choose an inspector who is authorized to complete the form required by the insurer and has experience with the building classification involved.
Depending on the applicable requirements, authorized professionals may include appropriately licensed home inspectors, building code inspectors, general or building contractors, professional engineers, professional architects, or other professionals recognized by the insurer.
For commercial properties, confirm that the selected professional is qualified to complete the specific commercial or commercial-residential inspection being requested. A professional who can complete one type of mitigation form is not automatically authorized to complete every other form.

7. Address Any Roof Deficiencies Identified Separately
A wind mitigation inspection may identify construction features relevant to wind resistance, but owners should separately investigate roof deficiencies that affect current performance.
These may include:
- Loose or deteriorated flashing.
- Open seams or damaged membrane.
- Missing or deteriorated roofing materials.
- Roof-edge deficiencies.
- Water intrusion or active leaks.
- Damaged rooftop equipment attachments.
- Maintenance concerns that may worsen during severe weather.
Corrective work should be based on the actual findings and the appropriate professional recommendations. Do not assume that a favorable mitigation inspection means the roof is in good overall condition.

8. Submit the Report and Supporting Evidence to the Insurer
After the inspection, review the report for completeness and submit it through the insurance agent or the process specified by the carrier.
Depending on the applicable form and requirements, the submission may include:
- The completed and signed inspection form.
- Required photographs.
- Supporting permits and invoices.
- Product documentation.
- Evidence of qualifying construction features.
- Additional information requested by underwriting.
Citizens reviews mitigation forms and supporting documentation and may reject incomplete submissions or request further verification. An inspection does not automatically guarantee a discount or a particular underwriting outcome.

9. Understand the Potential Insurance Benefits
When qualifying mitigation features are properly documented and accepted by the insurer, a property may be eligible for applicable wind mitigation credits.
However, owners should not assume that:
- Every wind-resistant feature qualifies for a discount.
- Every commercial building uses the same mitigation form.
- A wind mitigation inspection guarantees lower premiums.
- A mitigation inspection guarantees coverage or prevents nonrenewal.
- A mitigation report replaces other underwriting documentation.
Ask the insurance agent or broker to explain how the findings affect the specific policy and whether additional documentation or improvements could qualify for consideration.
10. Keep the Inspection Records Updated
Maintain the completed inspection, supporting documents, and records of subsequent roof or building improvements.
Keep:
- Inspection reports and completed forms.
- Roof replacement records.
- Permits and paid invoices.
- Product approval documentation.
- Photographs of relevant features.
- Records of improvements to wind-resistant components.
- Insurance correspondence concerning mitigation credits.
Contact the insurer before relying on an older report after substantial building changes or roof replacement. The insurer determines whether an updated inspection or additional documentation is required.
Bottom Line
A wind mitigation inspection is important because it documents qualifying features that may help a commercial building resist wind damage and may support insurance mitigation credits or underwriting decisions. For commercial roofs, the inspection can be one part of a broader strategy for understanding wind resistance, maintaining reliable records, and planning improvements.
The key is to use the correct inspection form for the building, hire an appropriately qualified professional, provide supporting documentation, and confirm the insurer’s requirements. Remember that wind mitigation and roof condition inspections serve different purposes: a building can have qualifying wind-resistant features while still needing roof repairs or maintenance.
