Our concrete roof has got wet and has caused mould in our

This answer was rated:

Our concrete roof has got wet and has caused mould in our hallway. We have been told to have the roof material removed and replace with a fibre glass cover. But this will not stop the mould inside. Should we not deal with the inside before the outside as we don’t want the water left in the concrete
JA: Have you replaced this before? If so, how long ago?
Customer: never still the original covering from when built over 60 years ago
JA: How long has this been going on? What have you tried so far?
Customer: It has been about a year now we have tried scrapping the ceiling and used several different products we were told would stop the mould before being told the roof outside had let water absorb into the concrete roof itself
JA: Anything else we should know to help you best?
Customer: We have had estimates to remove felt and recover with fibre glass but will this stop the interior issues and won’t it just seal the water already in the concrete?
You absolutely must stop the water coming in first, By replacing the roof cover, before anything else. Otherwise you won’t have any chance of permanently stopping the mould.You can certainly scrape off the mould at any time, but it will come back. The concrete will dry out naturally, but it will take some time, Then you can apply the antifungal treatment.

Thanks how long would it be before we can treat the inside and wont the outside still be damp when new cover is put on
It’s impossible to say how long it will take to dry out. When the weather turns, in the spring, you stand a better chance of it drying. If you have to remove the cover then and let it dry, then so be it, but for the moment you don’t have an option unless you can somehow use a tarpaulin to keep the weather out.
