Hi i was wondering if someone could help. I have had a problem with mould in my bathroom and finding yellow drips of water from walls and ceilings. I have had 3 roofers one sent by home emergency insurers. All 3 saying different things one saying roof is fine and it is condensation in the bathroom, other 2 saying problems with roof felt/membrane. Can anyone advise as I don't want to pay for roof repairs that are not needed and still have condensation issues. I Always get ripped off because my knowledge is so bad.
