A three-alarm fire heavily damaged the historic Roseway Theater in Northeast Portland early Saturday.

No one was injured in the Aug. 6 fire at 7229 N.E. Sandy Blvd. that took over 80 firefighters and support personnel to control.

According to Portland Fire and Rescue, firefighters were dispatched to the nearly 100-year- old building at 5:48 a.m. When they arrived, crews found the building was filled with dark black smoke. Command immediately called for a second alarm.

Crews forced entry into the building and began searching for the fire. However the floor began to collapse and the fire began burning through the roof. This forced command to pull crews back outside and fight the fire from the exterior or defensively.

Firefighters used aerial ladder trucks to pour water into the building in an effort to extinguish the fire and to keep it from spreading to adjoining businesses. To ensure adequate resources were available, commanders called for a third alarm. PGE and NW Natural alsowere called to the scene to make fire affected utilities safe.

The fire was under control, but crews continued to cool hot spots throughout the morning. Fire investigators are on scene, but must wait for the scene to stabilize before they are able to dig through the debris in search of a cause. Crews will likely be on scene throughout the day, and the investigation will likely take several days at least.

City crews were called to mitigate the water runoff caused by the firefighting efforts.

Fire officials are asking Portlanders to be extra careful in the hot weather because fires can quickly spread.
