Anyone have snow problems in bins in the northern states?

We had problems with snow blowing in under our grain bin eaves the last 2 years especially. They are nearly new bins and we are getting tired of trying to throw that snow out after every blizzard. We think we have eliminated that problem this spring by using spray in foam that you buy at like Menards to insulate walls with. We applied it while bins were still full before we emptied them and it really worked well. Applied it to the eave from inside and nothing leaked through to outside. Works best if bin is down about 1 ring so have room to work.

Snow would blow in through the vents. We made an envelope with road fabric and wire tied the envelopes over the flapping OEM bird guards that were made with 2" wire cloth. To stop the snow blowing in through the center fill hole we took a strip of the ridge vent material that they sell for asphalt shingle roofs (the stuff that looks like a coarse Scotch-brite), glued it an used 2 long wire ties (the 3/8" wide ones) to fill the gap between the lid and the bin. Some snow still blows in but not enough to require shoveling it out. Still check on the grain regularly and run the fans. My problem is how to stop condensation on the roof. The sun warms up the south side and the cold wind condenses it on the north side. Any Ideas?

I think that is why that little gap is left between the bin walls and the roof panels, (the one the snow blows in), so when. the condensation gets thick enough it will run down the under side and drip on the outside. When I was involved with building free stall barns and other steel sheds we would add a thin layer of insulation we called tough roll on top of purlins before applying the roof steel. Some guys used 1/4" styrofoam insulation called fanfold under steel roofs for that. I think in a grain bin the only was to accomplish something like that would be to get a spray foam contractor in when the bin is full, but if your bin roof is like mine it is so filthy it would need cleaned first so the spray foam would stick

We did the same thing. Worked well
