Direct Answer
If a commercial NNN lease states that the landlord is responsible for “structural repairs” but does not specifically mention the roof, the owner or tenant should review the entire lease before deciding who must pay for roof repairs or replacement. The phrase may support an argument that certain roof-related work falls under the landlord’s responsibility, but it does not automatically settle every roofing dispute.
The key is to determine how the lease defines structural components, how it allocates routine maintenance and capital expenses, and whether it distinguishes between the roof structure, roof membrane, flashing, drainage, repairs, and replacement. The cause of the damage and any exceptions for tenant negligence or alterations may also matter.
The practical next step is to document the roof condition, review the relevant lease provisions with a commercial real estate attorney, and obtain written clarification before authorizing significant work or agreeing to pay for it. A roofing inspection can establish what work is needed, but the lease and applicable law determine how responsibility should be allocated.

Who This Applies To
- Commercial property owners and landlords
- Tenants operating under triple-net (NNN) leases
- Commercial real estate investors and asset managers
- Retail property owners and tenants
- Industrial and warehouse property managers
- Commercial brokers and property management teams
- Owners dealing with major roof repairs or replacement costs
Not for: This guidance does not determine the legal meaning of a particular lease or replace advice from a commercial real estate attorney. The answer depends on the signed agreement, applicable law, and the specific facts.
1. Understand What “Structural Repairs” Means in Your Lease
The first step is to identify exactly how the lease uses the term “structural repairs.” Some agreements define structural components explicitly. Others use broad language without identifying individual building systems.
Depending on the wording and circumstances, structural components may include:
- Foundation and footings
- Load-bearing walls
- Structural framing and supports
- Roof deck and structural roof supports
- Other components essential to the building’s structural integrity
However, the roof assembly contains several distinct components. A roof membrane that prevents water intrusion is not necessarily treated the same way as the structural deck supporting it.
For example, repairing a deteriorated roof deck may fit more naturally within a structural-repair provision than replacing a small section of membrane. The lease’s definitions and allocation of maintenance responsibilities still need to be reviewed before reaching a conclusion.
2. Review the Entire Lease, Not Just One Sentence
Do not interpret the structural-repairs clause in isolation. Review the following provisions together:
- Landlord’s obligations: Does the landlord promise to maintain or repair structural components?
- Tenant’s obligations: Must the tenant maintain, repair, or replace the premises?
- Roof-specific provisions: Does another clause mention the roof, membrane, flashing, drains, or roof replacement?
- Capital expenditures: Are major repairs and replacements treated differently from routine maintenance?
- Common-area maintenance: Can roof expenses be charged back through operating expenses or CAM?
- Casualty and insurance: Who is responsible for storm damage and insured losses?
- Tenant alterations: Who pays for damage caused by tenant-installed equipment or contractors?
- Default and remedies: What procedures apply when a party fails to perform a required repair?
A separate provision may clarify, qualify, or limit the general structural-repair language. The complete agreement must be considered.
3. Distinguish Between Roof Structure and Roof Covering
One of the most important questions is whether the lease distinguishes the structural roof from the waterproofing system.
| Roof Component or Work | What to Check in the Lease |
|---|---|
| Roof deck or structural supports | Whether these components are expressly classified as structural |
| Roof membrane | Whether the tenant or landlord maintains, repairs, or replaces the waterproofing system |
| Flashing and roof penetrations | Whether these are included in roof maintenance or building-envelope obligations |
| Roof drains and drainage components | Whether drainage maintenance is assigned separately |
| Routine leak repairs | Whether the lease treats small repairs as tenant maintenance |
| Full roof replacement | Whether capital replacement is expressly assigned to one party |
| Storm-related damage | Whether casualty provisions and insurance requirements control the response |
These distinctions are particularly important when a lease assigns structural repairs to the landlord but gives the tenant broader maintenance obligations.
4. Determine Whether the Work Is Maintenance, Repair, or Replacement
The nature of the work can affect the contractual analysis.
Consider these examples:
- Routine maintenance: Clearing roof drains, removing debris, or arranging scheduled inspections.
- Localized repair: Repairing a small membrane tear or replacing a damaged flashing detail.
- Major repair: Addressing widespread leaks or extensive deterioration across a roof section.
- Structural repair: Repairing damaged roof decking or structural supports, where the lease classifies these as structural components.
- Capital replacement: Replacing an aging roof system or major building component.
These are practical categories, not universal legal definitions. A lease may assign responsibility differently, and a major repair does not automatically become the landlord’s responsibility merely because it is expensive.
5. Check Whether the NNN Lease Shifts Costs to the Tenant
A triple-net lease commonly allocates property taxes, insurance, and maintenance expenses to the tenant. However, NNN leases are not all identical.
Some agreements reserve major structural repairs or capital replacements to the landlord. Others impose broader obligations on the tenant, including certain roof repairs or replacement costs.
Check whether the agreement:
- Requires the tenant to maintain the entire building
- Excludes structural components from tenant obligations
- Separates repairs from replacements
- Allows capital expenses to be passed through to the tenant
- Requires capital expenses to be amortized over the useful life of an improvement
- Excludes expenses caused by the landlord’s negligence or another party’s actions
Do not assume that the term “NNN” alone establishes who must pay for a complete roof replacement.
For additional context, review this commercial real estate discussion of roof, structural, and capital-expense provisions in NNN leases.
6. Determine Whether the Tenant Caused or Contributed to the Damage
Even when the landlord retains responsibility for certain structural components, the lease may make the tenant responsible for damage caused by its negligence, misuse, contractors, or alterations.
Examples include:
- Damage caused by rooftop HVAC installation
- Membrane punctures caused by tenant contractors
- Unauthorized roof penetrations
- Damage from improperly installed equipment
- Failure to perform maintenance expressly required by the lease
Document the actual cause of the damage rather than assuming that the party responsible for the building component must always pay. A qualified roofing professional can help identify the damage and its likely cause, while the lease and legal advice determine the contractual implications.
7. Obtain a Commercial Roof Inspection
If the dispute involves a significant repair or replacement, obtain a written assessment from a qualified commercial roofing professional.
The report should identify:
- The affected roof areas and components
- The nature and extent of the deterioration
- Whether the issue is localized or widespread
- Any active leaks or water-intrusion risks
- The likely cause, where it can reasonably be determined
- The recommended corrective work
- Whether repair or replacement appears appropriate
- Photographs and supporting observations
This report helps separate the technical question—what work is needed—from the contractual question—who is obligated to pay for it.

8. Review the Lease Before Authorizing Major Work
Before approving a substantial repair or replacement, assemble the relevant lease language and technical documentation.
Your review package should include:
- The signed lease and all amendments
- The structural-repair clause
- The tenant maintenance clause
- Any roof-specific or capital-expenditure provisions
- The roofing inspection report
- Repair estimates or replacement proposals
- Relevant insurance and casualty provisions
- Previous correspondence about roof responsibility
Ask a commercial real estate attorney to interpret the provisions together. Do not assume that an informal conversation or a previous repair establishes a permanent allocation of responsibility.
9. Request Written Clarification From the Other Party
If the lease is ambiguous, raise the issue in writing before the disagreement escalates.
A useful written request should:
- Identify the relevant lease provision.
- Describe the roof condition and affected components.
- Attach the inspection report or repair estimate.
- Explain why responsibility is unclear.
- Request the other party’s written position.
- Propose a meeting or lease amendment if necessary.
Keep the communication factual and avoid making definitive legal claims before the lease has been reviewed.
10. Consider a Lease Amendment for Future Roof Work
If the parties agree that the existing wording is unclear, they can consider an amendment that expressly allocates responsibility for the roof.
The amendment should address:
- Roof structure and supporting components
- Roof membrane and waterproofing system
- Flashing and penetrations
- Drains and drainage components
- Routine maintenance and inspections
- Emergency leak repairs
- Major repairs and full replacement
- Capital-expense allocation and amortization
- Damage caused by tenants or their contractors
- Insurance claims and storm damage
- Notice, approval, and repair procedures
Have a qualified commercial real estate attorney draft or review the amendment so that the language matches the parties’ intentions and the rest of the lease.
11. Do Not Assume That Residential Landlord Rules Automatically Apply
Commercial leases and residential leases can be governed by different statutory frameworks. Florida’s Section 83.51, Florida Statutes, addresses landlord maintenance obligations, but its application must be considered in the context of the applicable statutory part and tenancy type.
For a commercial NNN lease, do not rely on a residential landlord’s statutory duties as a shortcut for interpreting the contract. Have an attorney familiar with commercial leasing review the applicable law and the signed agreement.
12. Keep a Complete Roof and Lease Record
Regardless of which party ultimately pays, maintain a clear record of the roof’s condition and the decisions made.
Keep:
- Signed lease and amendments
- Roof inspections and condition reports
- Repair proposals and invoices
- Photographs before and after work
- Maintenance records
- Warranty documents
- Insurance correspondence
- Written agreements about responsibility
- Records of completed repairs and replacements
These records help future property managers, owners, tenants, insurers, and attorneys understand the roof’s condition and the parties’ documented decisions.
Bottom Line
If an NNN lease makes the landlord responsible for “structural repairs” but does not mention the roof, do not assume that either party automatically has responsibility for every roofing expense. The answer depends on the complete lease, the distinction between structure and roof covering, the type of work required, any tenant-caused damage, and applicable law.
Obtain a professional roof assessment, review all relevant lease provisions, and get legal advice before committing to major costs. If the parties agree that the language is unclear, a written lease amendment can help prevent the same dispute from recurring.
