If you've got the standard tile roof you might want to check and make sure that there's not a lot of dead leaves or other debris piling up in the valleys. During the torrential downpour today water started pouring down one of our inside walls. I went up in the attic to see where the roof was leaking and found water streaming in from half way down one of the valleys. There were a couple of leaves poking out between the tiles and the valley metal where the water was coming in so I pulled them, and whatever else I could grab, out and the water stopped coming in. When the rain let up I went outside to check the roof and, sure enough, the valleys were piled high with gunk.
So, something else to go on the periodic maintenance list.
