This is an attic insulation issue. If your attic was insulated enough, you would have snow on the roof.
The heat transfer out the roof is dependent only on the indoor temperature, the outdoor temperature, and the attic’s insulation. None of those parameters depend on whether or not you are running a server farm (unless the server farm is so powerful that it increases the indoor temperature to uncomfortable levels, and prevents the furnace from even running.
