Fire investigators tell us a construction crew accidentally started a fire on the roof of a building in the University Village Shopping Center on North Nevada at around 10 a.m. Monday.
That fire has now been extinguished.
Several trucks were called in because they needed the heavy rescue trucks to reach the roof.
Crews and fire investigators are on scene testing the integrity of the building.
Fire officials said no one was injured, but two construction workers were treated for smoke inhalation. There is no word on the extent of damages to the building.
