The door opening is only 8 ft. high, so an 8 ft. door will be fine. But it seems in order to lift the door higher it requires different springs, drums, cables, etc. The motor is an issue, but the most commonly mentioned type is a jackshaft.
I'm looking to get a head start on this so it doesn't slow down the builder trying to find the solution - they will be breaking ground next week.
