[Links to external PDF] | The Swiss have been doing this for years, protecting buildings and even entire towns from the avalanches that thunder down on them every spring. |
So it seems that something to split the snow *around* the pipe in

hunting around turns up some appropriate parts -- one of which
is a spare section of roof panel. Here's the hack in progress;
next step here is to dremel out the two little mounting tabs [cut lines
marked on the white surface]. The flanges get pop-riveted together
where they cross, to give nice rigidity to the top and bottom.
