How should a GC handle a roofing subcontractor default or defective installation on a Florida commercial project?

Direct Answer

A GC should handle a roofing subcontractor default or defective installation on a Florida commercial project as a documented contract-performance and risk-management issue, not simply as a workmanship dispute. The first priorities are to protect the building from further damage, preserve evidence, identify the contractual requirement that was not met, give the subcontractor the notice and opportunity to cure required by the contract, and involve the surety, owner, architect/engineer, manufacturer and counsel when appropriate.

The GC should avoid immediately removing or covering defective work unless emergency conditions require it. Photograph and document the condition first, preserve relevant materials and records, and obtain a qualified assessment of the cause and extent of the defect. If the roof is leaking, temporary protection and emergency repairs may be necessary to prevent additional damage while the dispute is being evaluated.

Florida’s Chapter 558 construction-defect procedure can impose notice and opportunity-to-repair requirements before certain construction-defect actions. For claims subject to Chapter 558, the statute generally requires written notice describing the alleged defects and their locations, with specified time periods before an action may be filed. The statute also expressly states that its notice requirement is not intended to prevent an owner from completing a project that has not been substantially completed. Florida Statutes §558.003 and §558.004.

Because default, termination, retainage, bonding, payment, lien rights and construction-defect procedures can depend on the specific contract and project type, a GC should have Florida construction counsel review the contractual steps before declaring a subcontractor in default or terminating the subcontract.

Who This Applies To

• General contractors and construction managers
• Commercial roofing subcontractors
• Owners and developers
• Architects and engineers
• Sureties and bond administrators
• Construction attorneys and project counsel
• Florida commercial construction project teams

Not for: This FAQ provides project-management and risk-control guidance. It is not legal advice and does not determine whether a particular roofing subcontractor is legally in default. The applicable prime contract, subcontract, bonds, specifications, project type and Florida law should be reviewed before taking formal default or termination action.

1. Stabilize the Building First

If defective roofing is allowing water into the building, the GC’s immediate priority should be controlling further damage while preserving the evidence needed to determine responsibility.

Depending on the condition, this can include:

• Temporary roof protection
• Temporary leak repairs
• Protecting interior finishes and equipment
• Removing standing water where appropriate
• Protecting electrical or mechanical equipment
• Controlling roof access
• Documenting emergency conditions

The GC should document whether emergency work was performed and why. Emergency mitigation should not automatically be treated as acceptance of the subcontractor’s work or as a waiver of contractual rights.

2. Determine Whether It Is a Defect, Incomplete Work or a Coordination Problem

Not every roofing problem constitutes subcontractor default.

The GC should first determine what actually happened.

Condition	What to Investigate
Incomplete roofing	Was the work within the subcontractor’s scope and schedule?
Defective installation	Does the installation differ from approved documents or manufacturer requirements?
Roof leak	Has the actual source been established?
Damage by another trade	Who accessed or modified the roof?
Design issue	Could the condition originate from drawings or specifications?
Material problem	Were the correct products delivered and installed?
Weather-related condition	Was temporary protection required or improperly maintained?

This distinction is important before assigning responsibility or issuing a formal default notice.

3. Preserve Evidence Before Correcting Defective Work

Before substantial corrective work begins, the GC should create a clear record of the original condition whenever practical.

Useful evidence includes:

• Photographs and videos
• Exact roof locations
• Daily reports
• RRO observation reports
• Roofing subcontractor reports
• Approved submittals
• Shop drawings
• RFIs
• Change orders
• Manufacturer correspondence
• Inspection reports
• Material delivery records
• Weather records
• Testing results
• Warranty documents

If a concealed defect must be opened or removed, document the condition before disturbing it whenever reasonably possible.

4. Compare the Installation With the Contract Documents

The GC should identify the specific requirement that was allegedly not satisfied.

Compare the installed roof against:

• Roofing specifications
• Approved roofing submittals
• Manufacturer installation instructions
• Approved shop drawings
• Roof details
• Applicable product approvals
• Engineering requirements
• Change orders
• RFIs and approved clarifications
• Contract schedule requirements

For Florida projects, the GC should also verify applicable code and product-approval requirements. Florida’s Product Approval system contains approval information and limits of use for covered products and assemblies. Florida Product Approval Search.

5. Establish the Cause of the Problem

A leak should not automatically be attributed to defective roofing installation.

The investigation may need to distinguish between:

• Membrane installation defects
• Flashing defects
• Drainage problems
• Roof penetrations
• Mechanical equipment interfaces
• Damage from other trades
• Improper temporary protection
• Design deficiencies
• Material defects
• Building movement
• Condensation or non-roof moisture sources

For complicated failures, the GC may need an independent roofing consultant, RRO, engineer or other qualified professional to investigate before deciding which party is responsible.

6. Give the Subcontractor a Clear Written Notice

If the evidence indicates that the roofing subcontractor has not performed according to its contract, the GC should provide a written notice identifying the problem and the required corrective action.

The notice should generally identify:

• Project
• Roof area
• Date of observed condition
• Specific deficiency
• Relevant contract requirement
• Required corrective action
• Required response date
• Required completion date
• Inspection or verification requirements

The GC should follow the notice, cure and default procedures contained in the actual subcontract rather than relying on a generic form.

7. Follow the Contract’s Cure and Default Procedure

A GC should distinguish between defective work and a formal subcontractor default.

Many commercial subcontracts contain specific procedures for:

• Notice of deficiency
• Opportunity to cure
• Failure to prosecute the work
• Failure to maintain schedule
• Failure to correct defective work
• Failure to provide adequate supervision
• Failure to maintain insurance
• Abandonment
• Termination for cause

The GC should follow the actual contractual procedure and required notice periods. A poorly executed default notice can create a separate dispute even when the underlying roofing work is defective.

8. Do Not Automatically Withhold Every Payment

Payment disputes should be handled carefully. A GC should distinguish between legitimate contractual rights concerning disputed or defective work and an unsupported blanket withholding of payment.

Florida law contains specific payment requirements affecting construction participants. For example, Florida Statutes §713.346 addresses payment of undisputed obligations for labor, services and materials and establishes procedures concerning nonpayment. Florida Statutes §713.346.

For contracts entered into on or after July 1, 2026, DBPR’s construction-industry guidance also states that licensed contractors generally must compensate subcontractors or suppliers within specified periods after receiving payment, unless there is a bona fide dispute regarding the amount due or the contract provides otherwise within the statutory framework. Florida DBPR Construction Industry FAQs.

Because retainage, backcharges, disputed amounts and setoffs depend heavily on the contract and circumstances, the GC should have counsel review the proposed payment action when the dispute is significant.

9. Notify the Surety When a Bonded Subcontractor Is Involved

If the roofing subcontractor provided a performance bond, the GC should review the bond and subcontract together and follow the bond’s notice requirements.

The GC should not assume that simply declaring the subcontractor in default automatically activates the surety’s obligations.

Depending on the bond and circumstances, the surety may have rights concerning:

• Investigation of the alleged default
• Opportunity to respond
• Completion arrangements
• Selection of a replacement contractor
• Financial information
• Documentation of the remaining work

The exact procedure depends on the bond language and governing contract.

10. Separate Performance-Bond Issues From Payment-Bond Issues

The GC should understand that a performance bond and a payment bond serve different purposes.

• Performance bond: generally addresses performance of the bonded contract, subject to its terms.
• Payment bond: generally protects certain parties seeking payment for labor, services or materials, subject to statutory and contractual requirements.

Florida Statutes §713.23 establishes requirements concerning payment bonds, including notices and time limitations for certain bond claims. Florida Statutes §713.23.

The GC should therefore obtain and review the actual bond rather than assuming that every construction bond provides identical protection.

11. Consider Whether the Roofing Warranty Is Available

A defective installation may also create a manufacturer-warranty issue.

The GC should determine:

• Whether the manufacturer has inspected the roof
• Whether a warranty has been issued
• Whether deficiencies were identified
• Whether required corrections were completed
• Whether the manufacturer’s warranty remains available
• Whether the roofing contractor’s workmanship warranty applies

If the roof has not yet received its final manufacturer warranty inspection, the GC should coordinate that process rather than assuming the warranty will resolve the installation problem automatically.

12. If the Subcontractor Refuses or Fails to Cure, Develop a Completion Plan

If the subcontractor does not correct the problem within the applicable contractual process, the GC may need to evaluate completion by another contractor.

Before doing so, document:

• Original defective condition
• Notice provided to the subcontractor
• Opportunity to cure
• Subcontractor response
• Remaining work
• Estimated cost to complete
• Emergency mitigation costs
• Replacement contractor proposals
• Schedule impact
• Additional testing or investigation

The GC should obtain legal and surety advice before taking termination or takeover steps where the contract or bond requires specific procedures.

13. Do Not Let the Replacement Contractor Destroy the Evidence

If another roofing contractor is brought in, the GC should preserve the original condition and establish what work the replacement contractor is performing.

Document:

• Condition before replacement work
• Areas removed
• Materials discovered
• Defects found beneath the surface
• Corrective work performed
• Materials used
• Labor hours
• Testing
• Photographs before, during and after repair

This can be important if the GC later needs to demonstrate why additional completion or repair costs were incurred.

14. Use Chapter 558 Carefully When a Construction-Defect Claim Is Involved

Florida’s Chapter 558 establishes a statutory notice and opportunity-to-repair process for construction-defect claims subject to the chapter.

Under §558.004, the claimant generally must provide written notice of the alleged defects before filing an action, with the statute specifying different notice periods depending on the type of claimant/project. The notice must describe the alleged defects in reasonable detail and identify their locations sufficiently to permit inspection. Florida Statutes §558.004.

Chapter 558 also provides that the notice requirement is not intended to prevent completion of a project that has not been substantially completed. Florida Statutes §558.003.

Because the application of Chapter 558 depends on the specific claim, contracts and circumstances, a GC should involve Florida construction counsel before treating a particular notice as a Chapter 558 notice or taking litigation-related action.

15. Protect Against Additional Water Damage During the Dispute

A roofing dispute should not leave the building exposed while the parties argue about responsibility.

The GC should maintain appropriate temporary protection and establish a documented process for:

• Emergency leaks
• Temporary repairs
• Water removal
• Interior protection
• Roof access
• Weather monitoring
• Emergency communications
• Permanent corrective work

The GC should document whether emergency work is being performed to protect the project while the contractual dispute remains unresolved.

16. Calculate the Real Project Impact

The cost of defective roofing can extend well beyond the cost of replacing a membrane or flashing detail.

The GC should track:

Cost Category	Examples
Roof correction	Removal, replacement and reinstallation
Emergency protection	Temporary covers and leak response
Interior damage	Finishes, equipment or materials
Testing	Leak investigation or destructive testing
Consultants	Roofing consultant or engineering investigation
Schedule	Delay and remobilization costs
Replacement contractor	Completion and corrective-work premium
Closeout	Additional inspections and documentation

Keep these costs separately documented so the GC can distinguish original contract costs from costs caused by the defective work or default.

17. Keep the Owner and Project Team Informed

A significant roofing default should not remain solely between the GC and roofing subcontractor.

Depending on the contract and circumstances, the GC should coordinate communications with:

• Owner
• Architect
• Engineer
• Roof consultant
• Manufacturer
• Surety
• Insurance representatives where appropriate
• Construction counsel

Communications should remain factual and should distinguish confirmed observations from allegations or unresolved causes.

18. Avoid These Common GC Mistakes

• Declaring default before reviewing the subcontract’s default procedure.
• Removing defective roofing before documenting the original condition.
• Assuming every leak is automatically the roofer’s fault.
• Allowing another trade to perform undocumented roof repairs.
• Failing to notify the surety when the contract or bond requires notice.
• Withholding unrelated undisputed amounts without reviewing contractual and statutory requirements.
• Ignoring manufacturer warranty requirements.
• Failing to document emergency mitigation.
• Allowing the building to remain exposed during a dispute.
• Using a replacement contractor without preserving evidence.
• Sending informal emails that contradict the contractual notice process.
• Failing to obtain legal advice before termination when the consequences are significant.
