Advice needed please

Hello all
My brother's flat (top floor, 3 storey) had this damp/condensation area top corner of bedroom. The patch looked like was caused from broken gutter/roof tile...they are fixed now. But since plaster upon touch seems brittle. fully qualified plasterer going to do whole room. any advice on the damp/condensation tips? Flat I've noticed does hold moisture so plan is to fit trickle vents in every window, windows open few hours a day, shower when in door shut etc, would a plaster vent be ideal to fit in that room or make it too cold? TIA

Zinsser mould paint will keep black mould away from condensation but you didn't have a condensation problem, you had a leak.

A plaster vent has been illegal for about 30 years now. They are all plastic now health and safety.
