HARTLAND – A fire late Friday night damaged the roof and part of a vacant house in the Town of Hartland, Niagara County sheriff’s officials said.

A passerby spotted the flames at 2370 Quaker Road and called 911 about 10:20 p.m., authorities said.

Volunteer firefighters from Hartland and Barker put out the fire, which started in a rear interior wall and damaged the north side roof and the northeast corner of the house, authorities said.

The Niagara County Cause and Origin Unit is investigating the cause of the fire. The vacant house is owned by Robert Havens of Tonawanda, according to the Sheriff’s Office. Deputies said the owner had been at the home earlier in the day, renovating it in preparation for sale.
