Several emergency agencies responded to a roof collapse at a Breckenridge resort on Wednesday.

Luckily, no one was inside the Ten Mile room at the Village at Breckenridge when the roof caved in around 8:15 p.m.

Fire officials tell 9NEWS the collapse was likely caused by heavy snow. Jay Nelson with the Red, White and Blue Fire Protection District says the building was the old movie theater in Breckenridge. He says the snow Breckenridge has gotten over the last two weeks on the flat roof was too much for it to handle.

Breckenridge has received around 49 inches of snow in the last seven days.

Thursday, crews worked to knock down a wall at the convention center.

The structure was not attached to other buildings. The Ten Mile room is 4,524 square feet.

Nelson says about 70 families have been evacuated and all guests and employees at the Village at Breckenridge are accounted for.

Nelson says utilities will be shut off as fire crews and a structural engineer asses the damage.
