Water enters high and appears low. The ceiling mark is where it finally gave up travelling, not where it got in.
In detail
Roof repair & leak detection
Water runs along rafters, follows nail shanks, tracks down the top of a ceiling joist and drops through at the first gap it finds — which can be metres from the entry point and on the other side of a room. So we start in the attic rather than at the stain, looking for the trail: rusted nail tips, darkened sheathing, daylight at a penetration, staining that runs uphill of the mark downstairs. Then we get on the roof and check the suspects in order — flashing first, because that is where roofs fail.
What you get is photographs and a plain answer. Sometimes it is a step flashing that was never installed behind a dormer, a pipe boot whose gasket has perished, a nail that backed out, or a valley that was closed with sealant by someone in a hurry. Those are repairs, and we say so. Sometimes the covering is simply at the end of its life and patching it is throwing money at a roof that needs replacing — we say that too, and we would rather lose the repair than sell you three of them.

Questions
Asked most aboutroof repair & leak detection
Why is my ceiling stain not under the hole in the roof?
Because water travels. It runs along the underside of sheathing, down rafters and across the top of ceiling joists before it finds a gap to come through. That is why diagnosing from inside the room alone is guesswork, and why we start in the attic and work back up to the entry point.
Is it worth repairing an old roof or should I replace it?
It depends on what is failing and on how old the covering is. A flashing failure on a twelve-year-old roof is a repair and a good one. Granule loss, curling and brittle shingles on a twenty-five-year-old roof mean the covering is spent, and each patch buys less time than the last. We photograph what we find and give you the arithmetic rather than a verdict.
