This item does not have a snow load rating and the manufacturer recommends you keep the snow removed from the top with a soft broom or mop.
The only snow load rated shelters of this type we carry are the
ShelterTube shelters by ShelterLogic. These are available in both gray and green in sizes of 12 x 20 x 11, 12 x 25 x 11 and 12 x 30 x 11. They can resist winds up to 80 mph and snow/ground loads of 43 pounds per square foot (when used correctly).
