I am hoping someone could advise me whether there is a good method to dehumidify an attic.
While planning to replace an inefficient and noisy bathroom exhaust fan, I went into the attic and noticed the ducting was disconnected at the roof vent. It might have been this way for some time since I now obviously have wet and icy roof deck sections (I live in Toronto). The roof shingles themselves were only replaced 3 years ago so I am trying to avoid the risk of the decking rotting out and having to replace the entire roof. I have replaced the fan and faulty ductwork.
Can I place a household dehumidifier up there ? Are there commercial units geared for this ? I don't think waiting for it to dry on its own is right.
