The fire was held to the house and did not spread to nearby brush, a fire official said.
Radio reports from the scene indicated that the fire started in the kitchen. Gales said it spread through the walls and into the attic of the large, two-story home.
One hundred and three firefighters responded to the greater-alarm fire and fought through thick smoke to mount an aggressive attack on the flames, using chainsaws to cut through areas of the Spanish-style roof.
It took just over two hours to get the fire knocked down, Gales said.
Two firefighters suffered injuries other than burns and were taken to hospitals, Gales said.
Gales did not know the extent of the damage caused by the fire. The cause of the fire is under investigation.
