Materials and resilience questions
- What product line, color, and warranty tier are listed?
- Are accessories from the same system required for warranty eligibility?
- Will flashing be replaced, reused, or evaluated case by case?
- How will bad decking be priced if discovered after tear-off?
- Is upgraded wind, hail, or sealed-deck performance available or required by the insurer?
- Are attic intake and exhaust ventilation balanced?
- Are local code, HOA, wildfire, hurricane, or historic-district requirements relevant?

Red flags to slow down
- The estimate says “replace roof” but does not list tear-off, flashing, underlayment, and ventilation details.
- The contractor says permits are unnecessary without explaining local requirements.
- Rotten decking pricing is open-ended or missing.
- The bid relies on reusing old flashing without inspection notes.
- Warranty language is verbal only.
- You are asked to sign over insurance benefits without understanding the contract.
- The contractor pressures you to climb onto the roof or inspect unsafe areas yourself.
