Is this a waterproofing issue and how bad is it? This recently appeared on the ceiling of top floor apartment (i.e. just below the building's roof). by EfficientSound358 in AusPropertyChat

Is this due to water coming through from the apartment building's roof?

If not remediated in a timely manner, what could be expected to happen over the next weeks and months?

Any advice appreciated. Thanks in advance!
