Extract Fan Terminating in the loft

[rj101]

Hi,

We've just had a new bathroom installed including new ceiling, light and extractor fan. The new extract fan runs from the ceiling into the loft space. It was my understanding that the extract outlet would be fitted to the soffit board so it was terminating outside however the builder has left it screwed into a roof joist.

The builder has said there will not be any problems with it but whilst i'm not a expert surely this will become a damp problem in the very near future if warm air is extracting into a cold loft space

Am i wrong or is this shoddy work?
Thanks

Shoddy work, yes it will cause damp in the loft-space.

+1; your builder could not have installed a more efficient system for introducing rot-inducing conditions into your loft.
