I lived through that and where my father worked had a car park on the roof,
but luckily the driveway up to the roof had underground electric heating.
One problem was though that it was only running just before the first
employees arrived and a short time in the afternoon, resulting in it being
covered in black ice most of the rest of the time!

I'm too idle to watch it all.

The company I was training at as a technician apprentice had a nice line
in producing low voltage transformers used to pass a current through
buried frozen water pipes:-)

Wouldn't do much with blue poly now!
