Crystal Lake fire investigators, police and the state fire marshal are investigating a blaze that left a one-story home with about $80,000 in damage Saturday, authorities said.
The first firefighters on the scene shortly after 5 p.m. found heavy flames and smoke coming from the rear of the home on the 0-100 block of Barberry Drive.
The fire appeared to start in or around a detached garage and spread to the house, according to a news release from the Crystal Lake Fire Rescue Department.
Firefighters were forced to attack the blaze from the outside when they noticed signs of a weakened roof, according to the release.
Officials brought firefighters from other departments when the heat from the fire began to melt siding and break windows on neighboring homes.
The fire was under control by about 6 p.m., officials said, and no injuries were reported. The home's residents weren't there when the fire started.
The home was deemed uninhabitable.
Units from 10 departments responded, including Algonquin, East Dundee and Huntley.
