Ideas to seal these holes where roof trim meets brickwork in older house? It' a garage that was at some point turned into a larger bed room which I need to stay in for the time being. Problem is the room gets dusty as fuck and after strong winds I see leaves and such come through these gaps.

I have caulked the flat parts ok, just quwerying the brain trust for an easier/neater way for the sections around the cement. I've been pushing some foam rod in there and then caulking the hole but it's messy/ time consuming. I don't really see it from the ground but still

ideas?

thanks
