How should a board compare multiple condo roofing proposals?

Direct Answer

A condo board should compare multiple roofing proposals by first making sure every contractor is pricing the same scope of work, then comparing the proposals across roof system, installation details, exclusions, unit prices, contractor qualifications, schedule, warranty, quality control, and total project exposure—not simply by selecting the lowest lump-sum price.

For Florida condominiums, this is especially important because roofing systems can have different Florida Product Approval numbers, design-pressure limitations, HVHZ applicability, and installation requirements. The Florida Building Commission’s product-approval database identifies these limits for individual roof assemblies, so the board should verify that the proposed system actually applies to the project. :contentReference[oaicite:0]{index=0}

Florida condominium law also requires competitive bidding for covered contracts when the association’s payment under the contract exceeds 5% of the association’s total annual budget, including reserves, subject to statutory exceptions. The board is not required to accept the lowest bid. :contentReference[oaicite:1]{index=1}

Who This Applies To

• Florida condominium boards and associations
• Community association managers
• Property managers
• Owners’ representatives
• Roofing consultants and inspectors
• Engineers and architects assisting with re-roof projects
• Condominium owners reviewing major roof expenditures

Not for: A small emergency repair where there is no practical opportunity to obtain multiple proposals. This comparison process is primarily for planned repair, restoration, or replacement projects where competing proposals can reasonably be obtained.

1. Confirm That Every Contractor Received the Same Scope

This should be the first comparison.

Before looking at the prices, the board should ask:

• Did every bidder receive the same roof plans?
• Did every bidder receive the same specifications?
• Did every bidder inspect the same roof areas?
• Were the same quantities provided?
• Were the same alternates requested?
• Were the same unit prices requested?
• Did all contractors receive the same addenda and answers to questions?

A $500,000 proposal and a $600,000 proposal cannot be meaningfully compared if the first excludes work included in the second.

The board should resolve scope differences before treating the proposals as competing prices.

2. Compare the Actual Roof System

Do not compare proposals only by manufacturer name or membrane thickness.

Compare the complete proposed assembly:

• Membrane or roof covering
• Insulation type and thickness
• Cover board
• Attachment method
• Fasteners and plates
• Adhesives
• Flashing system
• Edge metal
• Drainage components
• Walk pads
• Penetration details

Two contractors can both propose “TPO roofing” while specifying materially different assemblies.

Florida Product Approval records illustrate why the complete assembly matters. Current approved systems identify the roof category, applicable code version, HVHZ status, design pressure, installation instructions, and other limits of use. :contentReference[oaicite:2]{index=2}

3. Verify Florida Product Approval and Wind Criteria

For a Florida project, the board should require each bidder to identify the applicable Florida Product Approval information for the proposed roofing assembly where required.

Compare:

• Florida Product Approval number
• Code version
• HVHZ applicability
• Design pressure
• Roof-deck compatibility
• Attachment requirements
• Installation instructions
• Applicable evaluation report

Do not assume that a product approved somewhere in Florida is automatically approved for every Florida location or roof configuration. The state’s database shows that some systems are approved for both HVHZ and non-HVHZ use, while others are limited to one or the other. :contentReference[oaicite:3]{index=3}

4. Compare Tear-Off Assumptions

One proposal may include complete tear-off while another may assume a recover system.

The board should identify:

• Number of existing roof layers assumed
• Removal requirements
• Disposal
• Existing insulation removal
• Substrate preparation
• Deck exposure
• Temporary protection
• Who pays for concealed conditions

If the proposals make different assumptions about tear-off, their prices should not be compared as though they represent the same project.

5. Compare Insulation and Cover Board

Insulation can materially affect both project cost and roof performance.

The board should compare:

• Insulation type
• Total thickness
• Number of layers
• Thermal performance
• Cover-board type
• Attachment method
• Code compliance
• Manufacturer requirements

If one proposal provides a different insulation assembly, the board should ask whether the difference is intentional and what effect it has on the project’s cost and performance.

6. Compare Flashing, Edge and Drainage Scope

Roof proposals sometimes focus heavily on the field membrane while leaving detail work unclear.

Compare whether each proposal includes:

• Perimeter flashing
• Parapet flashing
• Edge metal
• Scuppers
• Roof drains
• Drain strainers
• Overflow drainage
• Pipe penetrations
• Equipment curbs
• Expansion joints
• Walkway pads

Ask contractors to identify anything they have excluded rather than allowing the board to discover exclusions after award.

7. Compare Exclusions Line by Line

Exclusions can make a low bid look much cheaper than it actually is.

Common items to investigate include:

• Deck repairs
• Wet insulation
• Additional tear-off
• Structural repairs
• Metal replacement
• Drain replacement
• Equipment relocation
• Electrical work
• Permit fees
• Engineering
• Testing
• Manufacturer inspections
• Temporary protection
• After-hours work
• Resident protection

The board should create an exclusions comparison sheet rather than relying on a quick review of the proposal’s first page.

8. Compare Unit Prices for Concealed Conditions

A proposal should clearly explain how foreseeable unknown conditions will be priced.

Potential Condition	Useful Comparison
Roof deck replacement	Price per square foot
Wet insulation removal	Price per square foot
Additional insulation	Price per square foot
Drain replacement	Price per drain
Flashing replacement	Price per linear foot
Additional membrane	Price per square foot

The board should confirm what labor, materials, disposal, equipment, overhead, and profit are included in each unit price.

9. Compare Contractor Qualifications

A roofing proposal is also a proposal from a contractor, not just a price sheet.

Compare:

• Florida licensing
• Commercial roofing experience
• Condominium project experience
• Experience with the proposed roof system
• Manufacturer certification where applicable
• Comparable project references
• Project manager
• Site superintendent
• Safety record and procedures
• Insurance coverage
• Subcontractor involvement

The board should ask for references from projects of similar size and complexity rather than relying solely on the number of years the company has been in business.

10. Compare the Construction Schedule

A proposal should explain how the contractor intends to execute the work.

Compare:

• Mobilization date
• Estimated duration
• Crew size
• Daily production assumptions
• Material lead times
• Roof-area sequencing
• Resident-access requirements
• Parking and staging requirements
• Weather contingency
• Expected completion date

For an occupied condominium, the fastest theoretical schedule is not necessarily the easiest schedule to manage. The board should understand how the contractor will protect residents and maintain building operations while work progresses.

11. Compare Temporary Weather Protection

This deserves its own line item in a Florida re-roof comparison.

Ask each contractor:

• How much roof will be opened at one time?
• How will exposed areas be protected?
• What is the end-of-day dry-in procedure?
• Who inspects temporary protection?
• What happens if severe weather approaches?
• Who responds to an overnight leak?

The board should compare the actual procedure, not simply accept “weather protection included” as sufficient detail.

12. Compare Quality-Control and Observation

The proposals should clearly identify who is responsible for observing and documenting installation quality.

Compare whether the project includes:

• Preconstruction meeting
• Material verification
• Installation observations
• Seam inspections
• Attachment verification
• Flashing inspections
• Drainage inspections
• Manufacturer inspection
• Independent observation
• Final inspection
• Punch-list verification

If an independent RRO, consultant, architect, or engineer is involved, the board should understand exactly what that person is contracted to observe and what remains the contractor’s responsibility.

13. Compare Warranty Coverage

“20-year warranty” is not enough information for a meaningful comparison.

Compare:

• Manufacturer warranty term
• Contractor workmanship warranty
• Material coverage
• Labor coverage
• Leak coverage
• Wind-related exclusions
• Maintenance obligations
• Inspection requirements
• Warranty fees
• Transferability
• Warranty service process

Ask each bidder to provide the actual warranty documents or sample warranty language rather than only stating the number of years in the proposal.

14. Compare Maintenance Requirements After Installation

A new roof still requires ongoing maintenance.

The board should ask:

• What inspections are recommended?
• How frequently should inspections occur?
• What maintenance is required to preserve warranty coverage?
• Who can perform warranty repairs?
• Are annual inspections included?
• What maintenance documentation must the association retain?

The board can use the final maintenance requirements to build the property’s post-installation roof-management program.

15. Compare Resident and Property-Protection Measures

For an occupied condominium, the proposal should address more than the roof itself.

Compare:

• Resident notifications
• Noise controls
• Odor controls
• Pedestrian protection
• Balcony protection
• Window protection
• Parking restrictions
• Material staging
• Dumpster placement
• Daily cleanup
• Emergency access

A proposal that does not explain these issues should not be treated as fully comparable to one that provides a detailed occupied-building plan.

16. Compare Change-Order Procedures

The board should understand exactly how additional work will be approved.

Ask:

• Who can authorize a change order?
• What documentation is required?
• Are photographs required?
• Are unit prices already established?
• Can work proceed before written authorization?
• What markup applies to additional work?
• How are emergency conditions handled?

A proposal with a slightly higher base price may expose the association to less uncertainty if its unit prices, exclusions, and change-order procedures are substantially clearer.

17. Compare Total Project Exposure, Not Just Base Price

The board should calculate an apples-to-apples adjusted project cost.

Cost Category	Bidder A	Bidder B	Bidder C
Base contract	—	—	—
Required alternate	—	—	—
Engineering / permits	—	—	—
Known exclusions	—	—	—
Unit-price exposure	—	—	—
Warranty cost	—	—	—
Other required project costs	—	—	—
Comparable project cost	—	—	—

This prevents the board from treating the lowest headline number as automatically the lowest-cost project.

18. Compare the Contractor’s Assumptions

Every proposal should include an assumptions section.

Look for statements about:

• Roof measurements
• Existing roof layers
• Deck condition
• Insulation condition
• Access
• Parking
• Working hours
• Weather
• Equipment relocation
• Permitting
• Engineering
• Resident restrictions

Material differences in assumptions should be resolved before the board makes its selection.

19. Check for Conflicts of Interest

The board should document any potential conflict involving directors, officers, managers, or related parties.

Florida DBPR explains that Chapter 718 contains conflict-of-interest requirements, including disclosure of certain transactions involving directors, officers, relatives, and entities in which a director has a financial interest. :contentReference[oaicite:4]{index=4}

The board should follow the statutory requirements and its governing documents and obtain legal advice when a potential conflict exists.

20. Preserve the Bid Record

The association should retain the proposals, comparison matrix, questions and answers, addenda, contractor qualifications, and selection documentation.

Florida DBPR states that condominium official records include contracts for work and bids, with bids generally retained for one year. For qualifying associations with 25 or more units, certain bids and bid summaries must also be posted through the association’s website or mobile application under current requirements. :contentReference[oaicite:5]{index=5}

The board should therefore maintain a complete procurement file rather than retaining only the winning proposal.

21. Use a Structured Comparison Matrix

A practical board matrix can look like this:

Category	Questions
Scope	Are all contractors pricing the same work?
Roof system	Are the complete assemblies equivalent?
Code	Does the proposed system meet applicable Florida requirements?
Product approval	Is the applicable FL approval and design pressure documented?
Qualifications	Does the contractor have comparable project experience?
Exclusions	What work is not included?
Unit prices	How will concealed conditions be priced?
Schedule	How long will residents be affected?
Protection	How will the building be protected during construction?
Quality control	Who observes and documents installation?
Warranty	What does the warranty actually cover?
Closeout	What records will the association receive?
Total exposure	What is the realistic project cost after adjustments?

22. Do Not Automatically Select the Lowest Bid

Florida DBPR expressly states that a condominium association is not required to accept the lowest bid when competitive bidding applies. :contentReference[oaicite:6]{index=6}

That does not mean price is unimportant. It means the board can evaluate whether the proposals are actually equivalent and select the proposal that best satisfies the association’s documented project requirements.

The board should document the factual reasons for its selection, such as differences in scope, qualifications, warranty, schedule, exclusions, or project execution—not simply record that one contractor “seemed better.”

23. Ask These Questions Before the Final Vote

1. Are all three proposals based on the same scope?
2. Are the proposed roof assemblies genuinely comparable?
3. Does each proposed system satisfy the applicable Florida requirements?
4. Are the Florida Product Approval and design-pressure requirements documented?
5. What does each contractor exclude?
6. What unit prices apply to concealed conditions?
7. What is the realistic total project exposure?
8. What is the construction schedule?
9. How will residents and common areas be protected?
10. Who is responsible for quality-control observation?
11. What warranty is actually being provided?
12. What closeout documents will the association receive?
13. Are there any conflicts of interest?
14. Does the proposed contract comply with the association’s procurement requirements?
15. Can the board clearly document why the selected proposal meets the project’s requirements?

Bottom Line

A condo board should compare roofing proposals in this order: scope first, technical equivalency second, contractor qualifications third, exclusions and risk fourth, warranty and execution fifth, and price after the proposals have been normalized.

For Florida condominiums, the board should also verify applicable product approvals, design-pressure information, and roof-system limitations because Florida’s approval records are assembly-specific and can distinguish between HVHZ and non-HVHZ applications. :contentReference[oaicite:7]{index=7}

Competitive bidding requirements can also apply to covered condominium contracts exceeding 5% of the association’s total annual budget, including reserves, and Florida DBPR confirms that the association is not required to select the lowest bid. :contentReference[oaicite:8]{index=8}

The strongest comparison is therefore not “Which contractor gave us the lowest number?” It is “After putting every proposal on the same scope and accounting for exclusions, unknowns, technical requirements, execution, warranty, and total project exposure, what does each proposal actually provide?”
