Doing this - especially in solos in which you won't wish to share the fort with anybody - should be the very first thing you do every time you float out a Port-a-Fort.
As an additional bonus, doing so will mean that you also don't fall down once you walk backwards trying to avoid some incoming fire, forgetting there is a massive hole right behind you.
Port-a-Forts are fairly obvious targets, and while they aren't easy to take down it doesn't take much to fortnite traps destroy one of the staircase at the top where you will most likely be standing. If someone does ruin among those segments of their top then it's surely worth rebuilding it using metal (if you can) as speedily as possible, even when the immediate danger isn't coming from that direction.
