A home for sale near 40th Street and Indian School Road went up in flames Wednesday morning.
It was a passerby who saw smoke coming from the vacant house and called the Phoenix Fire Department.
"I saw just the entire roof... windows started bursting out," said Sophia Ovidea. "Flames were shooting very high.. soaked our backyard and our roof."
The home appears to be a total loss.
Investigators are trying to determine what caused it.
Neighbors told FOX 10 someone was working on the home's roof Tuesday, but it's not known if that had anything to do with it.
Video: FOX 10's Anita Roman reports from the scene.
