Every Clark job gets scoped to the specific problem, not a generic checklist.

Dark staining from winter condensation on roof sheathing gets HEPA-vacuumed and treated with a structural-wood-rated antimicrobial.
Fixing this prevents both the ice dam and the mold pattern that follows it in your Clark attic.
Balancing intake and exhaust is often the biggest factor in whether attic mold returns.
Gaps around recessed lighting, attic hatches, and plumbing stacks let warm interior air leak into the attic, driving condensation.
Insulation touching an actively moldy roof deck gets removed rather than treated in place.
This final check is what separates a real fix from a Clark attic that looks fine until next winter.
