QUICK action by neighbours and bystanders was not enough to save a Yamanto family's home from fire.
Witnesses including mail deliverer Callum Hamilton noticed smoke coming from the windows of the Deebing Creek Rd home just after 9am on Wednesday.
Firefighters received several triple-0 calls, however the fire had torn through the home before they arrived at the scene.
Mr Hamilton said the speed at which the fire spread was startling.
"By the time I got off the phone, the fire was coming out of the roof tiles and windows," he said.
"The whole house was up in two minutes."
Some Ipswich City Council workers who were in the area at the time alerted neighbours to the fire.
The intensity of the heat was such that a large section of the tiled roof caved in within minutes of the fire igniting.
Acting area commander Matt Bulow said firefighters from Ripley, Bundamba and Brassall responded.
"The roof caved in before we arrived," Mr Bulow said.
"Our crews entered around the side of the house and then opened the garage for better access.
"The fire was brought under control in about 10 minutes."
Distraught neighbour Maryanne Berry said the man who lived in the house had come to her aid just last Friday.
"I was cooking tacos for the kids and they caught fire in the oven," Ms Berry said.
"The smoke alarms were going off and I started screaming.
"The man heard it and ran across the road to make sure we were all okay.
"He is a very caring person, so when I saw that his house was on fire I was devastated for him and his young family."
The man declined the opportunity to speak to media on Wednesday.
A number of Ipswich detectives and forensic officers were on the scene as investigations got under way.
Senior Sergeant Robbie Goodger said investigators would keep an open mind as to the cause of the fire until more was known.
The fire appeared to have started in the kitchen area of the house, directly below a section of the roof where solar panels were installed.
