Often water runs to openings in the vapor barrier, such as at ceiling light fixtures.
If you lot can't see any telltale period marks, and since the stain is fairly minor, look at the underside of the roof for 'shiners.'

Fix Walls and Dormers
Water doesn't ever come in at the shingled surface.

This should comprehend the most leak-decumbent areas. Then reshingle, sliding metal footstep flashing behind the fascia board (the trim behind the gutter). The valley flashing, laid over the joint where the two roofs run into, should overlap the step flashing at to the lowest degree 2 in. If leaks go along to occur from ice dams, consider installing roof border heating cables. (Discover them locally at hardware stores or habitation centers.) Improved attic insulation and ventilation are usually the best means to prevent ice dams, but they might non be effective in this complicated leaky roof state of affairs.
