We are located in Northwestern Wisconsin, so we are no strangers to the cold and snow. The rollers are very reliable in ice and snow. We don't attempt to manage the water and as such it will not collect anywhere in the rail system and will not freeze and prevent the cover from working. The cover will operate with up to an 1/2" of frozen material on it. Loose snow must be removed before driving or attempting to retract the cover. Frozen rain breaks off easily.
