I store a few weeks of wood on a 6' X 20" side covered deck. I made small heavy duty pallets out of 2" X 6" to protect the deck floor. These go along the outside railing, for 1 row of wood. This year I found a brown tarp 4' X 20', that I tied to the inside of the railing. It really helped with the snow blowing in. For the little snow we got in the east this year.
