This is my second spring in this bungalow. Last winter we noted
interstitial condensation in the (boarded) attic and it was suggested
putting in roof vents would help so we did.

This year there are items in the attic, an office chair in particular,
which has mould on it.

So two issues -
Mould - why? How to cure?

water is getting in. Fix it.

Moss - why? How to clean/stop?

Remove with paintbrush. Copper wire might stop it.
