TROY — A vacant home sustained extensive damage after a fire Tuesday morning.

The Troy Fire Department responded to Monadnock Street around 3:45 a.m. to find the single-story ranch house well involved, according to Chief Mark Huntoon, who said flames were already shooting through the roof at one end of the structure.

The fire remained at a first alarm and several mutual aid towns assisted Troy in knocking down the blaze in about 45 minutes, Huntoon said. Crews spent the next few hours checking the scene for hot spots, he added.

No one was injured, and there were no occupants in the building, which Huntoon said has been vacant for at least six months.

With so much fire damage, he said the house is likely a total loss. The department notified the homeowner and the Office of the State Fire Marshal, Huntoon said. The cause remains under investigation.
