More than likely it is a type of "Single Ply" (TPO or DuroLast) & if so, not hot at all. Common color is white (doesn't absorb sunlight & therefore no need to reflect it back off). Common option # 2 is exposed fastener galvalume metal, & yeah, that gets blistery hot with a sunny day (regardless of the temperature).
Other recent pics on this page of the thread showed white, so I'm going with TPO. Not hot.
Roof access for building like that:
1. Ladder
2 Internal hatch.
3. Caged ladder on exterior.
4. Exposed ladder with the bottom 6 -8 feet missing or locked in the "up" location.
5. Interior stairs leading to a top door that is typically locked from the interior or dead bolted with double side key locks to prevent use.
Trump has essentially "back doored" his way into the highest level Federal job there is.
If he had to get an FBI background check to be a janitor @ some 2 office wildlife refuge in the middle of nowhere, he would not have passed.

FB is chock full 'o crazies.
Cuba doesn't want any boat traffic that they cannot control; the last thing is a zillion smaller boats with someone hiding under a stack of life jackets.
As to distance over to the Bahamas, something like Lauderdale to Bimini is gonna be your best route. Lots of fast boats make a day trip with 1 ~ 1½ hours East, spend a day, 1½ hours West.
"Crazy Greg" was known for that trip.
