A metal-roof proposal should describe an assembly rather than a panel in isolation. The existing covering, deck condition, underlayment, ventilation, penetrations, edge metal, flashings and attachment method all affect the scope. Ask what can be inspected before tear-off, what is an allowance, how concealed damage will be documented and priced, and which party is responsible for permits and inspections.
Ask for the exact tested system
The proposal should name the manufacturer, panel profile, substrate, thickness, finish, seam or fastener method and applicable Florida Product Approval or other accepted evaluation. Those documents include limitations and installation details. Wind design is tied to the address, building dimensions, roof geometry, exposure and risk category, so a single countywide wind-speed promise is not a substitute for project criteria.
Treat tear-off as a site decision
Some assemblies may be installed over an existing roof covering, but the answer depends on the building and proposed system. Existing layers, deck condition, moisture, weight, fastening substrate, manufacturer instructions, code and permit requirements all matter. A proposal should state whether tear-off is included and how the contractor will handle any condition that changes the approved scope.
- Exact panel, substrate, finish and accessory specifications
- Deck-repair allowance with unit pricing and photo documentation
- Underlayment, valley, penetration, wall and edge details
- Address-specific wind criteria and approved installation instructions
- Permit, inspections, cleanup, workmanship terms and manufacturer warranties
Before signing, verify the contractor’s active Florida license with the Department of Business and Professional Regulation and confirm that the proposal, permit application and product documents describe the same system. Product and workmanship warranties are separate promises; obtain both in writing and read exclusions before treating either as part of the value.
