We received a comment on the original post from Greg Ten Eyck with Safeway regarding the roofs at the Edgewater and Gambrills stores:
The roofs of the Safeway stores in Gambrills and Edgewater did NOT collapse. There was leaking, so the company closed the stores out of an abundance of caution. The roofs are being cleared and a structural analysis will be made to determine when the stores will reopen. They are expected to reopen on Tuesday.
