Diagnose the attic before choosing a fix
Dark staining on rafters or sheathing is usually the tail end of a longer moisture story, not the whole of it. A plan that holds up under Wilmington’s humidity has to track down how water or damp air is reaching the attic, address ventilation and insulation along with the growth itself, seal off the work area, and confirm afterward that conditions actually improved.

Wilmington context
Wilmington pairs a large historic district with postwar neighborhoods, barrier-island homes, and fast-growing inland communities. Salt air, wind-driven rain, hurricanes, flood exposure, high water tables, sandy soils, and intense sun require coastal detailing.
