My installer told me to just lay a piece of plywood over the top of
the unit for the winter. I happened to have a warped piece of luan
that was just the right size, so I lay a piece of 2x4 on the top of
the unit, lay the warped luan on top of that, and then strap it down
with a bungee cord. The rain and melted snow just run right off.
