Appears to be one heck of a comm setup on the roof.... either that or machine gun nests.
Not to worry-—about the roof stuff anyway. That looks to be construction staging. Note that the outside lifting/access gear is still in place. The roof gear looks to be finishing the inside. Need a place to stash his one book, doncha know? Later pics show the roof mostly cleaned off. And we still, sort of, want to know where he’s going to keep all his white hut records that he had his lawyers stash in a U-Haul as he was leaving DC? The storage bill on that stuff has to be eating into his surfing money.
