Hi,
I have received my report back from a survey completed on a house I'm purchasing.
It showed that the underlying to the roof needs replacing as defective and in some parts none at all.
Meter readings showed damp on both floors of the property, very high at the point of low ground floor.
I would imagine that the damp is likely coming from the defective roof as there is evidence of DPC injected on the external walls of the property.
I have 2 questions;
Does this require a whole new roof or isn't a simple job of replacing the underlying.
Once the root cause of the problem has been sorted, does more work to internal walls need completing or will fixing the problem eventually lead to the walls drying out.
Any advice would be appreciated. TYI 🙏
