I am trying to build an 8′ tall fence/screen on top of my parapet wall and not really sure how to secure it. The parapet wall has a metal coping on it and is a demising boundary between my property and my neighboor’s.
I am concerned that if I use screws to attach the wood base of the fence to the top of the parapet wall I would later on get water penetration(extremely bad). Should I do this and then silicone the around the screws to prevent water leakage or is this not enough?
should I just glue the bottom flange of the fence to the metal coping, use something like a “Gorilla Glue” product?
i’ve also thought about attaching the fence to the side of the parapet wall but that would be encroaching on the neighboor’s property so no go.
Does anyone have any suggestions for me? Any thoughts you guys would have would be very helpful.
