We have just managed to clear most of the snow off the roof of our caravan only to notice the roof seems to have sunken in with the weight of the snow. There is still a layer of ice on the roof & couldn't get the door open today as its frozen and don't want to force the door and damage the seals etc. Was wondering what would be best after we get in the van to put heating on and hope that it melts the ice but not sure what will happen to the roof if it will just "pop back up" anybody info would be great
