No attic here. As such, the flat roof is directly above the heated living space with only about 8" of buffer which is packed with insulation.
It may technically be poor design, but here in the Philly area, we don't usually get this much snow all winter, let alone in one shot. When it snowed just an inch or two the week before, there wasn't any problem.
Perhaps the insulation up there could use some improvement, but that would be a pretty hefty job to rip out all of the ceilings. If possible, I think I'm looking for a more external solution. Cleaner gutters, better gutters, gutter guards, maybe one of those heating elements mentioned earlier...
Although it may just be a matter of pushing the snow off the roof if it snows that much all at once.
