We recently moved into our new building (bungalow). Now after only 5 months we have noticed mold on the floor insertion stairs or hatch. The roof is a cold roof. The hatch is wet on the side facing the roof and the veneer is peeling off slightly there – mold is visible underneath.
We are now a bit unsure how to proceed here now.
a) How can mold occur here? Do we have to live with it in a cold roof and independently provide any insulation or the like?
b) Do we have to call in an expert to find out what the problem is or should we contact the house construction company directly?
c) Someone has an idea what we can do against mold here now? I am extremely annoyed that we have such issues after such a short time.
