Red flags in Oregon roof replacement quotes
- Whether tear-off or a layover is specified, and how many existing layers
- Decking replacement priced per sheet up front instead of decided mid-job

- Underlayment type and ice-and-water shield coverage
- Intake and exhaust ventilation
Commonly missing line items: drip edge, ridge vent or soffit intake, dumpster, disposal, and magnet sweep, permit and inspection fees, per-sheet decking allowance.
