The roof of a flooring business in St. Paul collapsed Sunday afternoon after a fire ripped through the building.

Crews responded shortly after 1 p.m. to a blaze at 315 Atwater St., said Jamie Smith, deputy chief of the St. Paul Fire Department. No injuries were reported, he added.

The address is listed as the location of Fulton Flooring.

Early in the afternoon, Smith said firefighters continued to work to extinguish the flames on the building's exterior.

"We are in defensive strategy, which means firefighters are not committing to the interior until they get in control of the fire from the exterior," Smith said, adding an investigation will begin when the fire is contained.

No details about the cause of the fire were immediately available.

By 2:30 p.m., the Fire Department posted on X that the bulk of the fire was out and crews were checking for hot spots. The city's Department of Safety and Inspections has scheduled the building to be demolished.
