Direct Answer
A general contractor evaluating a commercial roofing subcontractor bid in Florida should look beyond the lowest price. The bid should clearly identify the roofing system, scope of work, materials, labor, exclusions, warranty requirements, schedule, insurance, licensing, permitting responsibilities, wind-uplift requirements, and closeout documentation.
Florida adds important considerations because commercial roofing work must account for the applicable Florida Building Code, wind resistance, product approvals where applicable, jobsite safety, and subcontractor insurance requirements. Florida DBPR specifically states that roofing work cannot be subcontracted to unlicensed roofers; roofing work must be performed by employees of the licensed contractor or through a licensed employee leasing company. Florida DBPR licensing guidance
The practical goal is to determine whether each bidder is pricing the same scope, same level of compliance, same quality requirements, and same project responsibilities. A low bid that omits tear-off, substrate repairs, permits, testing, warranty requirements, protection of completed work, or proper closeout can become more expensive than a higher but complete bid.
Who This Applies To
- General contractors bidding commercial construction projects in Florida
- Construction managers and project managers
- Estimators comparing commercial roofing subcontractor proposals
- Owners’ representatives reviewing subcontractor qualifications
- Developers managing new construction or reroofing projects
- Facility teams involved in contractor selection
Not for: This FAQ is about evaluating a roofing subcontractor’s bid and qualifications before award. It is not a substitute for a project-specific roofing specification, structural review, engineering analysis, legal review, or permit determination.
1. Does the Roofing Bid Clearly Define the Entire Scope?
The first question should be whether every bidder is actually pricing the same work.
A commercial roofing bid should identify, as applicable:
- Roof areas and approximate quantities
- Existing roof system
- Roof system proposed for installation
- Removal and disposal requirements
- Existing insulation removal or replacement
- Cover board requirements
- Deck preparation or repair assumptions
- Flashing and edge-metal work
- Penetrations and pipe flashing
- Drains, scuppers and overflow drainage
- Roof curbs and equipment interfaces
- Walk pads and protection requirements
- Temporary weather protection
- Cleanup and debris removal
- Testing and inspection requirements
- Manufacturer inspection requirements
- Warranty requirements
Do not compare only the final lump-sum number. Build a scope comparison sheet so that exclusions and assumptions are visible.
2. Is the Roofing Contractor Properly Licensed for the Work?
Florida DBPR states that roofing work cannot be subcontracted to unlicensed roofers. The licensing status and the actual entity performing the roofing work should therefore be verified before award.
The general contractor should obtain and verify:
- Legal business name
- Florida contractor license information
- License status
- Qualified individual information where applicable
- Scope of work covered by the license
- Any applicable local registration or project requirements
Use the Florida Department of Business and Professional Regulation licensing resources rather than relying solely on a license number printed in the subcontractor’s proposal.
3. Does the Bid Address Florida Wind and Code Requirements?
Florida roofing bids should demonstrate that the proposed assembly is appropriate for the project’s applicable code and design requirements.
The estimator should look for information concerning:
- Applicable Florida Building Code requirements
- Project-specific design pressures
- Wind-uplift resistance
- Fastener and attachment patterns
- Edge and perimeter requirements
- Deck type and condition
- Roof assembly limitations
- Product approvals or evaluation documentation where applicable
- HVHZ requirements when applicable to the project location
The Florida Building Commission identifies wind-load requirements and roofing provisions within the Florida Building Code framework, and current code resources include the 9th Edition (2026) Florida Building Code development materials. The applicable code edition for the particular permit and project should be confirmed rather than assumed. Florida Building Commission Code Resources
A roofing proposal that simply says “install commercial TPO roof” without identifying the assembly, attachment method, design criteria, or applicable documentation may not provide enough information for a meaningful technical comparison.
4. Are the Materials and Roof Assembly Specifically Identified?
Two bids can both propose a “TPO roof” or “modified-bitumen roof” while containing materially different assemblies.
Look for:
- Manufacturer and product line
- Membrane thickness
- Insulation type and thickness
- Cover board
- Attachment method
- Adhesive or fastening requirements
- Base sheets and underlayments where applicable
- Flashing materials
- Metal edge system
- Drainage components
- Accessories
Where a project specification requires a particular assembly, the subcontractor should identify exactly how its proposal complies. If the bidder is proposing an alternate system, require the alternate to be clearly identified rather than buried in an exclusion or proposal note.
5. What Is Included and Excluded?
Exclusions are one of the most important parts of a subcontractor proposal.
Review exclusions for items such as:
- Deck replacement
- Wet insulation
- Structural repairs
- Roof drains
- Sheet-metal work
- HVAC curb modifications
- Penetration repairs
- Electrical disconnects or equipment relocation
- Permit fees
- Testing
- Engineering
- After-hours work
- Crane or hoisting requirements
- Temporary protection
- Waterproofing around adjacent construction
If an exclusion could reasonably become necessary during construction, determine in advance how that work will be priced and authorized.
6. Does the Bid Include a Realistic Schedule?
The roofing subcontractor should identify:
- Estimated mobilization date
- Material lead times
- Estimated duration
- Crew size or production assumptions
- Phasing requirements
- Weather contingencies
- Coordination with other trades
- Temporary weather protection
- Final inspection and closeout timing
Florida weather can materially affect roofing production. A bid should explain its assumptions rather than promising an unrealistic completion date without accounting for weather, material availability, site access, and other trades.
7. Are Insurance and Workers’ Compensation Requirements Satisfied?
This should be verified before the subcontractor begins work, not treated as paperwork to collect after award.
Florida’s Department of Financial Services states that construction employers with one or more employees generally must have workers’ compensation coverage, subject to applicable exemptions. It also states that general contractors are responsible for ensuring subcontractors have the required workers’ compensation coverage before work begins. Florida DFS Workers’ Compensation Coverage Requirements
Request and verify:
- Certificate of insurance
- General liability coverage
- Workers’ compensation coverage or valid exemption documentation
- Employer’s liability coverage where required by the project
- Additional insured requirements
- Policy expiration dates
- Umbrella/excess coverage if required by the prime contract
Florida DFS also provides a workers’ compensation Proof of Coverage database that can be used to verify coverage. Florida DFS Workers’ Compensation FAQ
8. What Warranty Does the Bid Actually Provide?
Do not accept a proposal that simply says “manufacturer warranty included.” Identify the actual warranty structure.
Ask:
- What is the contractor’s workmanship warranty?
- What is the manufacturer’s warranty?
- Who pays for warranty-related service?
- Is a manufacturer inspection required?
- What maintenance obligations apply?
- Are rooftop penetrations covered?
- What voids or limits the warranty?
- What documentation is required for warranty issuance?
- Is warranty registration included?
The warranty should be evaluated together with the proposed roof assembly and installation requirements rather than as a standalone marketing statement.
9. Does the Subcontractor Have Relevant Commercial Roofing Experience?
Ask for evidence of experience with projects comparable to the one being bid.
Useful qualification information includes:
- Recent commercial projects in Florida
- Similar roof systems
- Comparable project size
- Experience with occupied buildings
- Experience with reroofing
- Experience with complex penetrations and rooftop equipment
- Manufacturer certifications where required
- References
- Safety record and project history
- Key personnel who will actually supervise the project
Florida roofing guidance has historically emphasized prequalification and demonstrated commercial roofing experience, including manufacturer approval for specified systems on certain projects. Project specifications may impose additional qualification requirements. Florida roofing bidding guidance
10. Does the Bid Explain Quality Control and Closeout?
A complete roofing subcontractor proposal should address how the work will be inspected, documented and closed out.
Look for:
- Daily or periodic quality-control inspections
- Manufacturer inspections where required
- Testing requirements
- Photo documentation
- Correction of punch-list items
- Final roof inspection
- Warranty documentation
- As-built information where required
- Product data and submittals
- Maintenance recommendations
11. How Should General Contractors Compare Multiple Roofing Bids?
Use a bid leveling matrix instead of ranking proposals by price alone.
| Category | What to Compare |
|---|---|
| Scope | Are all roof areas and required work included? |
| Roof system | Are the assemblies and materials equivalent? |
| Code | Does the proposal address applicable Florida requirements and wind criteria? |
| Exclusions | What potentially expensive work is excluded? |
| Labor | Who will perform the roofing work? |
| Insurance | Are required coverages current and verifiable? |
| Warranty | What workmanship and manufacturer warranties are included? |
| Schedule | Are duration and material lead times realistic? |
| Experience | Has the subcontractor completed comparable Florida projects? |
| Closeout | Are inspections, documentation and warranty closeout included? |
| Price | Is the final number based on a comparable scope? |
12. What Are Red Flags in a Commercial Roofing Subcontractor Bid?
- Extremely low price with little scope detail
- Large number of vague exclusions
- No clearly identified roof assembly
- No wind-uplift or design-pressure information when required
- Unclear licensing status
- Missing or unverifiable insurance documentation
- No workmanship warranty information
- No manufacturer warranty information
- No project schedule
- No material specifications
- Unclear responsibility for permits
- Unclear responsibility for deck repairs
- Unclear responsibility for rooftop equipment interfaces
- No meaningful commercial references
- Proposal language that allows major scope changes without defined pricing
13. What Should Be Confirmed Before Awarding the Roofing Subcontract?
Before issuing a subcontract, the general contractor should have a documented bid-leveling process showing that the selected proposal has been evaluated for:
- License and legal entity verification
- Insurance and workers’ compensation
- Complete scope
- Materials and roof assembly
- Florida code and wind requirements
- Permitting responsibilities
- Exclusions and allowances
- Schedule and manpower
- Warranty requirements
- Safety requirements
- Quality-control procedures
- Closeout documentation
- Relevant commercial roofing experience
- Subcontract terms and change-order procedures
The final subcontract should make the responsibilities clear enough that the general contractor, roofing subcontractor, owner, architect or consultant, and other trades are working from the same scope.
