Seattle Fire Department (SFD) personnel responded to a fire on the roof and deck of the Alpha Sigma Phi fraternity house at the University of Washington at 3:49 a.m. Saturday morning.
When crews arrived, occupants inside were able to put out a small fire on the deck of the house, but firefighters found that flames extended into the attic, SFD said in a release.
Over 80 SFD personnel were dispatched to the two-alarm fire and crews brought it under control just before 5:00 a.m.
Seattle Fire says no injuries were reported, but the roof, attic, and top floor were significantly damaged.
SFD is investigating the cause of the fire.
