I just made sure to seal every layer as best as I could during installation and periodically check them by lifting back the headliner with a pry tool and inspecting for moisture. There's so many wires in those locations as well as curtain airbag components so one can never be to safe I suppose. I haven't had a single issue with leakage, thankfully, even after some broad seasonal and locational changes.
