A window in the house also exploded as residents gathered outside, with debris just missing them and members of the Jersey Fire and Rescue Service.
The fire broke out shortly before 4 pm when the Fire Service was called by an occupant of the house.
‘On arrival crews were faced with a large number of people in the street and a fire which rapidly escalated as a roof window exploded and landed in the street just missing fire crews and public,’ a Fire Service spokesman sad.
Firefighters wearing breathing apparatus entered the building to fight the fire and ensure all occupants had escaped.
The spokesman added: ‘Luckily all members of the household had got out the building, although one member of the family had to be treated at the hospital accident and emergency department for minor burns.’
Fire crews worked for the next two hours controlling the fire and its spread to adjacent properties.
