I live in a 1930 property with dorma loft conversion. I have noticed a damp patch on an external wall over the last week ( it is growing slowly) . I Am trying to work out where the water is coming from. there is a bathroom above, (dorma conversion) however it hasn't got any worse with the shower on. There is guttering outside , but that is clear from looking out of a window. ( i don't have a ladder big enough to have a proper look but pipes all look good, no leaking from external pipe for shower or water dripping down side of house in the rain.) I have dried it up with a hair dryer but the patch will go back to being wet within 30 minutes. Any ideas? I don't know whether to call a plumber/ builder ?
