 we're in the process of doing a bit of a cosmetic reno for a client who just bought a relatively new house. We discovered that there was some moisture. Pull off the drywall, we found a real mess. You can see that there is extensive mold and rot inside the cavity here. We actually found that with the moisture in there it created some arcing on this controller here that I think is for the electronic pool. I suspect that we've got a leak coming from the roof drains. Moisture is migrating down and has created a real problem. Of course this is compounded because the exterior finish on this is all some beautiful stonework that will all have to come off.
