NORTH ADAMS, Mass. —  The distinctive saw-toothed roof at the Hoosac Mill is missing a tooth — with a couple more showing cracks.

Further damage to the mill on Union Street could be seen on Monday.

The century-old textile mill, known as NoAMA (for North Adams, MA) was closed on Feb. 11 after a 30-foot section of the roof gave way and structural damage could be seen at another sawtooth.

The building is mainly used for storage but no one has been allowed in since its closure by the city. Owner Ariel Sutain has reportedly contacted engineers to review the building.

The state has cautioned property owners to remove snow after reports of nearly 200 structures across the state suffering collapse or structural damage.

Up to a foot of snow fell over the weekend beginning Friday and sleet and rain fell through Monday morning. That likely caused the brick end of the collapsed section to fall in. Several more cracks have appeared along the sawtooths near the collapsed section and around another significantly damaged area.

The roof's unique shape once allowed light to come in through windows on the east side. The windows were long ago covered over.
