Mold growth provided it is not just cosmetic mold which can simply be left alone can be cleaned from wood surfaces by blasting scrubbing or even simple surface wiping depending on the surface accessibility and smoothness. This occurs when the temperature of the sheathing drops below the dew point creating a thin layer of moisture on the substrate. In the vast majority of cases the mold growth is caused by condensation.

Seal off the area. Mold problems are indications of water problems. Water leaks and poor ventilation leading to condensation are the main roof defects which give rise to a variety of fungi moulds and insect attacks.
