A fire on the back deck of a home in Oakton, Va., traveled up the siding and onto the back roof, destroying the rear of the home.
Fairfax County Fire and Rescue officials said no one was home in the 3400 block of Ellmore Lane. When they arrived at 6:40 p.m. Saturday, crews discovered the back of the home in flames.
A second alarm was called before they were able to get the fire under control.
Investigators are trying to figure out exactly how the blaze started.
