The short answer
In Colorado's mountain towns, steep metal roofs built to shed heavy snow can dump snow and ice directly in front of, or onto, a garage door below, blocking it or damaging the track and panels. Clear the area carefully rather than forcing the door through packed snow.
Why this happens in Colorado's high country
Homes in Breckenridge, Vail, Aspen, and other mountain towns often have steep-pitched metal roofing specifically designed to shed heavy snow rather than hold it. When a roof sheds a large load at once, that snow and any ice with it can land right at the base of a garage door or slide down onto the door itself.
Safe things to check
A door that will not close, or one straining against something at the bottom, can be a sign of a snow or ice berm rather than a mechanical failure.
- Look for a snow or ice berm built up across the base of the door before trying to operate it.
- Listen for the opener straining without the door moving, which can mean it is pushing against packed snow.
- Stay outside any roof snow-slide zone. Have a qualified professional handle hazardous snow loads; do not stand below an overloaded roof to clear the garage entrance.
- Check panels and the bottom track for dents or bends after a heavy snow-shed event.
When to request service
If the track looks bent, a panel is visibly damaged, or the door still binds after the snow is cleared, request a professional evaluation rather than continuing to operate a door that is fighting resistance it was not designed for.
