The 1924 building housing the Roseway Theater in Northeast Portland appears to have been extensively damaged by a three-alarm fire Saturday. An aerial photograph taken by drone Sunday shows heavy damage to the roof of the building at Northeast 72nd Avenue and Sandy Boulevard. Firefighters said they relied on aerial ladder trucks to pour water from above because it was impossible to fight the fire from inside the building. The investigation into the cause of the fire, called in about 6 a.m. Saturday, remained under investigation and was expected to take several days.
