Firefighters battled a three-alarm fire at the Rheocast Company die casting maker in Germantown, WI, Monday morning.
The fire broke out around 8:30 a.m. and upon arrival at the scene, firefighters found black smoke coming from the roof of the building. A manager reported the roof was on fire in the foundry area.
The fire went to three alarms because fire officials needed more manpower because the fire was between the ceiling and the roof and spreading horizontally.
Firefighters discovered flames around a large roof fan spreading in all directions under the roof covering.
The roofing material was rubber over fiberboard over foam insulation on top of corrugated steel, fire officials said.
Primary and secondary searches of the 38,000 square foot building ended up conducted to ensure no other fires were breaking out.
Officials said due to multiple vats of molten steel and aluminum in the building, roof operations were dangerous and firefighters had to be careful while fighting this fire.
Fire officials said due to the roof covering and fire spread over 60 firefighters were on scene.
Firefighters brought the fire under control within two hours.
There were no injuries in the incident and the estimated loss as a result of this fire is around $125,000, officials said.
