Additional parts of the roof and walls at Thompson’s Appliance in Woodstock caved in Sunday morning, according to a Facebook post from Woodstock Fire and Rescue District officials.

The building, at 318 Clay Street, started losing its roof Wednesday, when a portion came down. Officials have blocked Clay Street to traffic and the surrounding sidewalks from pedestrians.

The recent snowfall may have precipitated the collapse, city officials said last week. Woodstock officials also condemned the building as it worked with owner Bob Thompson to assess the building’s condition going forward.
