We prefer to put a tarp over our roof for the winter to prevent ice from building up on top of the awning and also covering any of the various roof vents. This year we made a slight modification in the ridge pole design by using three (3) plastic foldup sawhorses to hold up the beam (2x2) with other 2x2s out over the slideout and a roof over the doorway. (seems that icy cold drips of water always dropped on the back of my neck when opening the door when coming or going from the RV. Maybe this design will prevent that.
We started to put up a tarp years ago when we discovered a considerable amount of ice buildup on top of the rolled up awning (in the valley between awning and roof) to the point that our rolled up awning was drooping in the middle about a 10 inches. The tarp allows the snow and ice to slide off of the roof.
