Cracked pointing, render or a leaking sill can send water onto the bay and mimic a roof leak.
Corners and back edges
Lead, felt and membrane bays all depend on sound upstands and corners. These are usually more revealing than the middle of the roof.
Let the room dry after the repair
Plaster around a bay can remain damp for a while. Decorating too quickly can bring staining or blistering back before the fabric has dried.
