I have an old concrete garage roof that is leaking. I plan to attach a layer of pressure treated wood then glue an EPDM sheet to the surface.
I understand how to install a drip edge on the sides however, I'm not sure what to do where the flat portion abuts a short arched piece. Images below. I'd rather not cut it off or attempt to refinish it to a taller edge at this time if possible.
Is it totally insane to just fill the corner with caulk or other adhesive? What would a professional do?
