For spray on roofing Cork paint [is greater than] polyurethane foam. What's the mechanism for mold growing on metal? I know there's mold growing on the outside of the ISS, but what, trapped moisture?

Plain steel is notorious for mold problems due to constant condensation , most examples come from the container home movement when aspirating creatures are dwelling inside a box making constant humidity.
The external spray on roofing I mention is expensive but solves 99% of the issues mentioned, rust, maintenance, drafts, bridging, condensation, hardware issues are generally solved, worth noting It’s not that expensive compared to the labor and materials required to fix up a hut into an efficient home
