So I was wondering how hard it is to take the cable through the tiles
into the loft?

Depends on your roof construction. Under the eaves would probably be
easier.

If you've got a fairly tatty old roof like mine it's a doddle to find a
cable-sized gap to run it through, between a couple of tiles. Been
there, done that.

Even if there are suitable gaps you still have to get up there to thread
it through :-)
