My shed roof slopes front to back and the RHS butts up against a building, there's an overhang on the building of 20cm going over the shed roof, which offers some protection, but I'm concerned that in heavy rain, water running down the roof could flow a little sideways and down between the roof felt and the building.
I don't think flashing is needed because rain would have to be coming nearly horizonally to hit the few cm of wall above the roof, under the building overhang, but I could definitely do with something with a small lip on it that I can fit underneath the felt.
Any suggestions - or advice to say this is a bad idea
