SOUTH GLENS FALLS — Fire tore through Common Roots Brewing Co. on Monday night, destroying a large portion of the building hours after the owners broke ground for an expansion of the business.

The blaze was reported around 7:15 p.m., and firefighters arrived to find flames coming through the roof on the northeast corner of the 58 Saratoga Ave. business, the area closest to the street and the neighboring apartment building at 56 Saratoga Ave. No injuries were reported, and the brewery had been open at the time the fire broke out.

Firefighters from at least seven companies in Saratoga, Warren and Washington counties descended on the scene, using two ladder trucks to pour water on the building from above. But the stubborn fire spread throughout the front section of the business, damage heaviest where brewing equipment had been located.

Parts of the roof collapsed and were consumed by fire, but a firewall kept the flames from spreading to the back half of the building.

The fire seemed to have been knocked down and brought under control shortly after 9 p.m., but some flames were still visible in spots as firefighters pulled down sections of walls and the roof to get at hidden hotspots.
