Waterloo Fire Rescue had a tough time putting out a fire that destroyed a Waterloo townhouse early Friday morning.

Fire crews responded to the fire on Grey Silo Road at 2 a.m., where platoon chief Dean Good said they found the fire in the rear of the home.

"They attempted to do an interior attack to try to extinguish the fire thinking it was just an attic fire," he said.

However, when additional fire crews arrived to assist, the roof and the second floor became fully engulfed, pushing crews to tackle the fire from outside.

Despite the combined efforts, it took fire crews two hours to get the fire under control.

"The fire was very stubborn," said Good. "It ended up the whole house being a loss."

Damage to the home is estimated to be more than $500,000. There were no injuries.

Good said the cause of the fire is under investigation at this time.
