My husband found it helpful to use an endoscope camera plugged into his cell phone to view the area around the leak to diagnosis the problem. The snakelike camera was inexpensively purchased online but should be at least 6 feet long and have a strong light source built-in. Access was either through a nearby junction box, or if necessary, through a small hole in an inconspicuous spot that can be patched later. If it’s not actively raining, someone on a ladder should use a hose to pour a heavy water shower over the suspected vent flashing. Anyway, that’s what he did the last time a mysterious water stain showed up on our ceiling (one story home).
