Roof ventilation

    I have two questions regarding the ventilation in our attic.

    Firstly, we have rock wool insulation that has been installed by the previous owner right up to the eaves, with the exception of area around the vents in the soffit where the insulation has been drawn back to allow proper ventilation. Should the insulation be drawn back from the remaining area around the eaves, or is it not going to cause any problems? The insulation was done 7 years ago and the attic still looks very dry.

    Secondly, we have had a bathroom fan installed, and its been piped to one of the vents in the soffit (relatively closely). Is this safe or could the moist air cause problems with mould on the surrounding timber or even be blown back into the attic space and cause problems?
    Should we pipe it directly through a vent in the roof itself instead?

    Cheers,

    Up through the roof is the best method of extraction

    If the fan is a standard 4" type with flexible ducting it's prob doing nothing .

    It can be done through a soffit but needs proper fitting and fan
