Fire destroyed a Dover Township home Friday morning, leaving two middle-aged men homeless, a fire official said.

Dover Township Deputy Fire Chief Brian Widmayer said crews were called to a mobile home in the 200 block of Delaware Avenue about 7:40 a.m.

As crews were rushing to the scene, they were being notified that flames had already eaten through the roof of the home, Widmayer said.

Firefighters battled the blaze from the outside, but couldn't get in, he said.

"The roof came down on the house," Widmayer said, destroying the trailer and everything inside.

No one was hurt, but one of the men who lived there was transported to York Hospital by ambulance because he needed medication, the deputy chief said.

The two residents are being assisted by the York-Adams Chapter of the American Red Cross, he said.

Widmayer estimated total damage at $30,000. The residents had previously been insured, but that insurance recently expired, he said.

Three cats that lived in the home could not be found, according to Widmayer, but someone reported seeing one of them running outside, so it's unclear how many of the cats survived.

Widmayer said the cause of the blaze has been ruled undetermined, because there wasn't enough left in the rubble to figure out what caused it. It is not considered suspicious.

One of the residents told firefighters a lit cigarette ignited a mattress, but that can't be confirmed, Widmayer said.

Assisting Dover Township at the scene were firefighters from Dover Borough, West York, Manchester Township and West Manchester Township, he said.
