Doors ext. mount freezing

[motefam]

Has anyone mounted Wyndstar roll-up doors or any other roll-up doors with the exterior mount in a cold/harsh climate. I have limited bay length and need to mount the doors outside, but I'm worried about freezing issues.

I have another brand mounted outside. After four troublefree years of use we had minor problems during a stretch of subzero temps last winter. I think ice may have built up in the head. Door would only raise half way. Stops were readjusted and we were back in business.
Planning to add another this fall for an IBA.
