Can the weight of snow damage an aluminum horse trailers roof?
If there is enough snow. Snow is deceptively heavy and the weight can cause damage to trailers. The trailers roofs aren’t designed to withstand much load they need to save weight with the roofing so that they can strengthen the floor to support more weight. Also the trailer loses structural rigidity when its doors are open, so if you see lots of snow on your roof, clear it off before opening the doors. I’ve seen the roof collapse when someone opened the doors to a custom utility trailer with an aluminum roof and steel everything else. this happened with just 16 inches of snow on the roof. If it is less than 8 inches it should not be a problem. And snow weighs over 5 lbs per cubic foot (can be as high as 6 or 7 lbs/cubic foot) so if you have a 16 foot by 8 foot roof with one foot of snow on it then it weighs over 640 lbs.
