What the job involves
Roof leaks are harder to diagnose than they look because water runs along battens and drops onto the ceiling a metre or more from the entry point. A good leak repair starts in the loft with a torch and moisture meter, traces the water back to the source, then fixes the cause — usually a flashing, a popped nail, a slipped tile, a pipe boot, or a valley.
Patching the visible stain without finding the source is a placebo. Within a season the leak reappears, often in a different room.

Why does my ceiling stain appear far from the leak?
Water enters the roof, runs along a rafter or batten until it meets a low point, then drops onto the ceiling. The entry and exit points can be a metre or more apart, which is why a ground-up diagnosis matters.
Will a leak repair stop the damp patch from coming back?
If the true source is fixed and the ceiling has time to dry fully, the damp patch will usually dry out within 2–6 weeks. If it reappears after drying, the root cause was not the one that got fixed — call the roofer back.
