For heavy snow areas, it is best to purchase a shelter that uses a round frame, as opposed to a peak or barn style. Round style shelters shed snow very well and can usually deal with the relatively small amount that is retained. We also offer several snow load rated peak shelters that are designed with extra reinforcement to deal with the weight. One example is the Shelterlogic 12x25x11 ShelterTube Snow Load Rated Shelter - Gray
