My wife had lots of problems with leaks in her new build flat from a balcony above it, it took Redrow 8 years to sort it out sending in lots of different trades people and replacing the ceiling many times.

It turned out that the sealing under the door on the balcony was poor and rain could blow under it.

What I am saying it is that is normally the “joints� that get you with any tanking.
