Direct Answer
Commercial new construction roofing in Florida typically moves through a defined sequence: design and roof-system selection → bid documents → subcontractor bidding → proposal review → contract and submittals → permitting and product-approval verification → material procurement → deck and substrate preparation → roof installation → inspections and quality control → punch list → manufacturer inspection/warranty → closeout.
For Florida projects, the roofing scope must be coordinated with the applicable Florida Building Code, project-specific design requirements, local permitting requirements and the approved roof-system documentation. Florida’s Product Approval system provides searchable approvals for roofing products and assemblies, including information such as applicable code version, limits of use, design pressure and installation instructions. :contentReference[oaicite:0]{index=0}
For a new commercial building, the roofing contractor is therefore not simply installing a membrane after the building is constructed. The roofing scope begins during design and bidding, where the roof assembly, attachment method, insulation, drainage, flashing, wind requirements, penetrations and warranty requirements should be defined before construction begins.
The strongest process is: design → bid → award → submittals → permit/code coordination → procurement → deck readiness → installation → inspection/QA → punch list → warranty → closeout.
Who This Applies To
- Commercial property developers
- General contractors
- Owners’ representatives
- Commercial roofing subcontractors
- Architects and design teams
- Construction managers
- Commercial building owners
- Florida project managers
- Owners developing warehouses, retail centers, offices, medical buildings and other commercial facilities
Not for: This article is a general construction workflow. The exact roofing requirements depend on the building design, location, roof system, contract documents, applicable code edition, local amendments, permitting authority and project specifications.
1. Roofing Begins During Design
The roofing process should start well before a roofing subcontractor receives a bid package.
The design team should establish:
- Roof configuration
- Roof slope
- Drainage strategy
- Roof system
- Insulation requirements
- Cover board requirements
- Vapor-control requirements where applicable
- Flashing details
- Roof-edge details
- Penetrations
- Equipment curbs
- Roof access
- Wind-uplift requirements
- Warranty requirements
Roofing should also be coordinated with structural, mechanical, electrical and plumbing design so that rooftop equipment and penetrations do not create unresolved conditions during installation.
2. Establish the Applicable Florida Code and Product Requirements
The project team should establish which Florida Building Code edition and local requirements apply to the permit and project.
Florida’s Building Commission maintains the state’s code-development and product-approval resources, including a dedicated roofing technical track. The Commission’s current materials also show ongoing work associated with the 9th Edition (2026) Florida Building Code. :contentReference[oaicite:1]{index=1}
The project team should therefore verify the applicable code edition and permit requirements rather than assuming that every project uses the newest code materials available online.
3. Develop the Roofing Bid Package
The roofing bid package should give each subcontractor enough information to price the same work.
A good package may include:
- Roof plans
- Roof details
- Specifications
- Roof assembly requirements
- Insulation requirements
- Flashing details
- Drainage details
- Roof-edge requirements
- Equipment-curb details
- Wind-design criteria
- Warranty requirements
- Testing and inspection requirements
- Project schedule
- Alternates
- Allowances
The more complete the bid documents, the less opportunity there is for contractors to make materially different assumptions about the work.
4. Bid the Roofing Work
The general contractor or construction manager typically solicits proposals from qualified roofing subcontractors.
Roofing bidders should review:
- Plans and specifications
- Roof areas
- Roof system
- Insulation assembly
- Substrate
- Perimeter conditions
- Penetrations
- Drainage
- Equipment coordination
- Schedule
- Warranty requirements
- Material lead times
They should also identify exclusions and assumptions before submitting a final price.
5. Compare Roofing Proposals on Scope, Not Just Price
The lowest roofing number does not necessarily represent the lowest cost for the same completed roof.
| Bid Category | What to Compare |
|---|---|
| Roof system | Manufacturer, assembly and material specifications |
| Insulation | Type, thickness, R-value and attachment |
| Attachment | Mechanical, adhered or other specified method |
| Flashing | Walls, curbs, penetrations and edges |
| Drainage | Drains, scuppers, gutters and accessories |
| Wind requirements | Design pressure and approved assembly |
| Warranty | Manufacturer and workmanship coverage |
| Schedule | Mobilization, installation and completion |
| Exclusions | Work not included in the base price |
A proposal comparison should normalize these assumptions before the project team selects a subcontractor.
6. Award the Roofing Subcontract
Once the roofing subcontractor is selected, the contract should establish the scope, price, schedule and responsibilities clearly.
The contract package should address, as applicable:
- Base scope
- Contract price
- Alternates
- Allowances
- Change-order procedures
- Schedule
- Payment terms
- Insurance
- Warranty requirements
- Testing
- Inspection requirements
- Cleanup
- Closeout documentation
7. Submit the Roofing Materials and Assembly for Review
Before installation, the roofing subcontractor generally prepares submittals showing exactly what it intends to install.
Depending on the project, submittals can include:
- Product data
- Roof-system assembly
- Manufacturer information
- Florida Product Approval documentation
- Installation instructions
- Wind-uplift documentation
- Insulation information
- Flashing details
- Fastener information
- Adhesive information
- Color selections
- Warranty information
Florida’s Product Approval database allows project teams to search by product, manufacturer, code version, category, approval status and other criteria. Individual approval records can identify the approved use, design pressure, limits of use and installation instructions. :contentReference[oaicite:2]{index=2}
8. Verify the Roof Assembly, Not Just Individual Products
A roof is an assembly of components that must work together.
The team should verify:
- Membrane or roof covering
- Insulation
- Cover board
- Adhesives or fasteners
- Deck type
- Edge conditions
- Flashing
- Penetrations
- Attachment pattern
- Wind-uplift performance
A Florida Product Approval record can contain assembly-specific information, including design-pressure limits and installation instructions. For example, current approval records identify specific roofing assemblies and their approved limitations rather than simply approving an entire manufacturer’s product catalog. :contentReference[oaicite:3]{index=3}
9. Coordinate Roofing With the Rest of the Building
Many roofing problems begin as coordination problems.
The roofing subcontractor should coordinate with:
- HVAC contractors
- Plumbing contractors
- Electrical contractors
- Sheet-metal contractors
- Structural trades
- Solar contractors where applicable
- Fire-protection contractors
- Equipment suppliers
Before the roof is closed up, the project team should know where rooftop equipment, curbs, pipes, drains and other penetrations will be located.
See How Should HVAC Replacement Be Coordinated With Roof Replacement?.
10. Verify the Roof Deck Is Ready
Roof installation should not proceed over an unsuitable or unresolved substrate.
The roofing team should verify conditions such as:
- Deck type
- Deck condition
- Fastener compatibility
- Moisture concerns
- Openings
- Penetrations
- Curbs
- Structural conditions
- Surface cleanliness
- Readiness for the specified assembly
Any unresolved deck or structural issue should be documented and addressed through the project’s established process before it becomes concealed.
11. Material Procurement and Delivery
After the submittals are approved, the contractor can proceed with procurement in accordance with the project schedule.
The project team should track:
- Membrane or roof covering
- Insulation
- Cover board
- Fasteners
- Adhesives
- Flashing materials
- Edge metal
- Drainage components
- Accessories
Material substitutions should not be treated as informal field decisions. The project team should follow the contract’s substitution and submittal procedures.
12. Prepare the Building for Roofing
Before installation begins, the general contractor and roofing subcontractor should coordinate site logistics.
This can include:
- Material staging
- Roof access
- Hoisting
- Crane operations
- Delivery routes
- Temporary protection
- Weather protection
- Fall-protection coordination
- Protection of completed work
- Coordination with other trades
For occupied or partially operational facilities, the logistics plan should also address occupants, deliveries, noise and building access.
13. Install the Roof System
Installation should follow the approved drawings, specifications, manufacturer’s requirements and approved assembly documentation.
The sequence will vary by roof system but can involve:
- Deck preparation
- Air or vapor-control components where specified
- Insulation installation
- Cover board installation
- Membrane or roof-covering installation
- Seam treatment
- Flashing
- Penetration detailing
- Perimeter and edge installation
- Drainage details
- Equipment-curb detailing
The installer should follow the manufacturer’s installation instructions and the approved project documents.
14. Manage Weather During Installation
Florida roofing projects must account for weather interruptions, particularly during periods of heavy rainfall and tropical activity.
The contractor should maintain a plan for:
- Daily weather monitoring
- Temporary dry-in
- Protection of exposed substrates
- End-of-day closures
- Water management
- Material protection
- Restart procedures after rain
The objective is to prevent an incomplete roof section from becoming a source of water intrusion during construction.
15. Perform Roofing Quality Control During Installation
Roofing quality control should occur throughout installation rather than waiting until the roof is complete.
Depending on the project, the quality-control process may include:
- Daily observations
- Photographs
- Material verification
- Fastener verification
- Seam inspection
- Flashing inspection
- Perimeter inspection
- Penetration inspection
- Drainage inspection
- Documentation of deficiencies
For larger projects, the owner or general contractor may also use an independent roof observer or consultant to provide additional quality-assurance observation.
See What Is an IIBEC Registered Roof Observer (RRO)?.
16. Coordinate Required Inspections
Inspections should be coordinated according to the permit, project specifications and authority having jurisdiction.
The project team should know which inspections are required by the local building department and which are additional contractual or quality-control inspections.
These should not be confused with manufacturer inspections or independent consulting observations. Each serves a different purpose.
17. Complete Roofing Punch-List Work
As installation nears completion, the project team should identify incomplete or deficient work.
The punch list can include:
- Incomplete flashing
- Missing accessories
- Unfinished seams
- Improper penetrations
- Damaged materials
- Drainage deficiencies
- Edge details
- Cleanup
- Sealant deficiencies
- Protection of completed work
Each deficiency should be assigned, corrected and verified before final closeout.
18. Coordinate the Manufacturer’s Final Inspection
Where the specified warranty requires manufacturer inspection, the project team should schedule it before final closeout.
The manufacturer may review installation details and identify deficiencies that must be corrected before issuing the applicable warranty.
The project team should retain:
- Inspection report
- Correction documentation
- Final warranty
- Manufacturer correspondence
19. Complete Roofing Closeout Documentation
Roofing closeout should create a permanent record of what was installed.
A complete package may include:
- Final roof plans
- Approved submittals
- Product information
- Florida Product Approval documentation
- Installation instructions
- Inspection records
- Testing records
- Photographs
- Permit documentation
- Final approvals
- Manufacturer warranty
- Contractor workmanship warranty
- Maintenance requirements
- Cleaning requirements
- Roof-access requirements
- Final punch-list documentation
These records become important later when the owner needs to perform maintenance, investigate a leak, transfer the property or establish the roof’s history.
20. Turn the New Roof Into a Maintenance Asset
Closeout should not be the end of roof management.
The owner should establish a roof record containing:
| Record | Purpose |
|---|---|
| Installation date | Track roof age |
| Roof system | Identify installed assembly |
| Manufacturer | Warranty and service reference |
| Warranty | Track coverage requirements |
| Product approvals | Document approved system |
| Final drawings | Future maintenance and modifications |
| Maintenance requirements | Preserve roof performance |
| Inspection records | Establish condition history |
See What Documentation Should I Keep for My Commercial Roof Warranty?.
21. Establish the Post-Construction Maintenance Program
The owner should establish a recurring roof inspection and maintenance program after turnover.
The program can track:
- Roof inspections
- Drain cleaning
- Flashing condition
- Sealants
- Penetrations
- Rooftop equipment activity
- Storm inspections
- Repairs
- Warranty requirements
Maintaining the roof from the beginning creates a documented history that can be useful for future repairs, warranty service and eventual replacement planning.
22. New Construction Roofing Timeline
| Stage | Primary Objective |
|---|---|
| Design | Define roof system and building interfaces |
| Bid | Obtain comparable roofing proposals |
| Award | Execute roofing subcontract |
| Submittals | Confirm materials and assembly |
| Permitting | Coordinate applicable code and permit requirements |
| Procurement | Secure approved materials |
| Deck readiness | Confirm substrate is ready |
| Installation | Install the approved roof system |
| QA/QC | Document installation quality |
| Inspection | Complete required and contractual inspections |

| Warranty | Complete manufacturer requirements |
| Closeout | Deliver permanent roof records |
| Maintenance | Begin ongoing roof management |
23. What Developers and GCs Should Watch Most Closely
The highest-value controls are generally established before the first roll of membrane reaches the roof.
The project team should pay particular attention to:
- Complete and buildable roof details
- Correct roof assembly selection
- Wind-uplift requirements
- Florida Product Approval documentation
- Deck readiness
- Drainage design
- Penetration coordination
- Rooftop equipment sequencing
- Material compatibility
- Weather protection
- Quality-control documentation
- Manufacturer warranty requirements
- Complete closeout records
Florida’s Product Approval records demonstrate why assembly-level verification matters: approved roofing products can carry specific limits of use, design-pressure information and installation instructions rather than functioning as unrestricted approvals for every building condition. :contentReference[oaicite:4]{index=4}

Bottom Line
Florida commercial new construction roofing is a project lifecycle, not simply an installation activity. The process starts with a buildable design and comparable bid documents, continues through contractor selection, submittals, product-approval and code coordination, procurement, deck preparation and installation, and ends with inspections, punch-list completion, warranty issuance and a complete closeout package.
Florida’s Product Approval system provides project teams with assembly-specific information such as approved use, design pressure, limitations and installation instructions, making product and assembly verification an important part of Florida roofing procurement and construction. :contentReference[oaicite:5]{index=5}
The strongest process is design → bid → award → submittals → code/product verification → procurement → deck readiness → installation → QA/QC → inspections → punch list → warranty → closeout → maintenance.
