Replacing the covering and correcting drainage are related but distinct scopes. A bid may retain existing geometry unless it explicitly includes changes. Owners should know whether persistent water collection is being investigated or simply covered by new material.

What to do next

Ask for the intended drainage approach and any design responsibilities. Compare modifications to insulation, outlets, curbs, and transitions where applicable. Keep structural questions assigned appropriately so the roofing allowance does not imply work that has not been designed.
