D.C. Schools officials said a roof fire Sunday at Eastern High School didn't affect areas used for classes, so the school opened as usual Monday morning.
Thick, black smoke could be seen for miles around Sunday afternoon after a rubberized roofing material construction crews were using caught fire.
The building where the fire happened is undergoing renovations. Eastern High has been using portable classrooms all year, so classes went on as planned on Monday.
A D.C. Fire and EMS official said the blaze grew very quickly and went to two alarms. Seventy-five firefighters were able to contain the flames to the roof. Workers were inside the building when the fire started, but were able to get away unharmed.
Investigators are trying to figure out exactly what sparked the fire.
