Abstract
A roll-up overhead door assembly which is selectively moved up and down to open and close an opening and which is guided along sides of the opening by columns, the door having an open position, a closed position and a cleaning position. The door includes a drum positioned proximate the top of the opening. The door panel is attached to the drum such that when the door assembly is in an open position the door panel is wound around the drum. The drip guard partially surrounds the drum and is positioned and sized to catch residue falling from the drum or door panel overhead. The door panel is sized such that in the closed position the door panel is connected to a point on the drum so that the panel does not significantly overlap the drum.
