A Kambah family has had a lucky escape tonight after their house started filling with smoke.
ACT Fire & Rescue was called to the Bacchus Circuit property just after 10 o'clock.
Firefighters arrived a short time later and discovered the smoke was coming from roof installation.
ACT Fire & Rescue says the smoke was caused by heat from a downlight.
Fire crews quickly removed a small section of the insulation and are now ventilating smoke from the home.
All occupants safely self evacuated after ringing emergency triple zero (000).
