On an inspection this week our professional snagger identified a moisture patch on a ceiling in the dining room. We were concerned about the high moisture and so the Site Manager visited in concern the ceiling was in jeopardy. He was somewhat unhelpful and said the issue was sorted and we were trying to scare the customer. After a frank discussion, it was agreed to bore a hole in the ceiling.
There was a huge amount of collected water above the ceiling and it continued to drain like this for several hours; the below video shows it still draining after an access hole was cut through to investigate its origin.
It is a good example where the site managers do not often have the experience to identify underlying serious issues like this, which frankly was dangerous.
