Damage is pegged at $180,000 after a kitchen fire on Riberdy Road near Ledyard Avenue.
Crews were called around 2:30pm to the house just off Walker Road near the airport.
The resident in the home got out safely and believed the flames started in the kitchen area.
Chief Fire Prevention Officer John Lee says unattended cooking gets the blame.
Fire crews were challenged when part of a roof came down while they were knocking down the flames.
There were no injuries.
