Start with conditions, not a product
The staining you can see on rafters or sheathing is the easy part to spot. The harder, more important work is tracing the moisture back to its source, keeping tabs on attic humidity, judging how far it has spread into insulation and framing, sealing off the work area from the rest of the house, and confirming the fix afterward.

Cary context
Cary's building boom ran through hot, humid Piedmont summers, and a lot of that era's roof framing used ventilation baffles and soffit vents sized for builder-grade code minimums rather than the region's actual attic heat load. Complex rooflines on premium subdivision homes add valleys and dormers that are common points for slow leaks to reach attic sheathing unnoticed.
