On a couple of occasions, teenage boys engaged in parkour (overcoming urban obstacles by climbing or leaping) and attempted to gain access to our roof via our motorhome’s permanent ladder, despite the extension part of the ladder not being there. To combat this behavior, I installed a metal barrier that is easily removed if necessary. I used a galvanized piece of sheet metal with eight holes punched in it, four U bolts, and eight nuts and lock-washers. You could even paint your name or some other greeting on the metal, if so inclined. Since I have installed the device, I have not had any more problems.
