I dont know how climates up there vary from the climates in the south, but alot of folks use the crawl space under thier house to dry roots.... kind of a make shift root celar. get a guy to dig out a part for 5 an hour, and put in some benches to hold everything above the soil, and put in a fan to pull the air out through a vent near the area.... and you are good to go... and if it is your place... get rid of the un cool roomate. get a new roomate that is cool and that you trust....
