And in another room:
We have a cathedral ceiling, very little roof space, and a tin roof. We're in Melbourne, Australia, which is in the middle of winter and we've been getting a lot of cold and wet weather recently.
The thing is, I'm not at all a handyperson, and am a new homeowner, so I'm pretty new to not only knowing how to investigate and fix this, but even knowing what sort of professional to call.
It's unlikely I have the skills to fix this myself, so my question is more - what sort of tradesperson should I be calling? And if I need to investigate it first to provide more information to them, what exactly should I be looking for?
