Where's mold coming from?

Hello.
I recently found mold in my bedroom at the top of one wall and farther down the same wall, as well as on my floor. I'm thinking moisture is getting in at the top of the wall. I thought the moisture might be coming from one of three sources:
1. From a leak in the new roof I had installed last January. It's made of a white rubberized material. I have a flat, sloped roof that's surround by a parapet with roof tiles along the edge. I've checked for breaks in the material and along seams, but haven't seen any.
2. From roof tiles being removed from the parapet, causing water to run straight down the side of the house instead of dripping 3" outside the edge of the house. But all the roof tiles are in place.
3. From gaps in the mortar of my brick house. I didn't see any gaps.
4. From my window. But the mold is above the window. I would expect mold to appear only below the window if the window were the problem.
I've included photos. Any ideas as to what the source of the moisture might be?
