I had a plywood subfloor and ijoists with lots of snow and rain before I got the roof on ..... Drilled a few holes in the floor to prevent too much pooling. The crawlspace and ijoists ended up with a lot of surface mold which I was really worried about at first but it was only really on the surface. Once I got the roof on..I set up two of these fans either side of the crawlspace to get air flow moving into and out of the space and then a few small dehumidifiers. Had these running for weeks. After.. I rented a fogger from Home Depot and hit it with Concrobium to be extra sure. Plywood and OSB subfloor material is designed to hold up to these conditions during typical construction periods.. I had a bit of delamination in spots but nothing major.
