The Dollar General Store located at 10551 Commerce Street in Summerville remains closed after the roof collapsed in a portion of the store last week.  WZQZ News spoke with employees of the store who said that the roof collapsed in the receiving room where the store receives its stock.  The store was closed immediately and employees were notified not to report for work.  WZQZ News has reached out to Dollar General Corporation, whose headquarters are in Goodlettsville, Tennessee, about the damage and plans for repairs at the retail store.  As of Sunday, the online listing for the store was still saying the store was open – that information is incorrect.
