Heavy snow is being blamed for a roof collapse at a business outside Fredericton on Saturday. No one was injured when the roof at Signature Sounds in Hanwell caved in yesterday morning. The Upper Kingsclear Fire Department responded to collapse and tell the CBC that staff were setting up equipment inside the building when they heard the roof crack before it collapsed in an area where no one was working. With more snow in the forecast fire officials are advising home and business owners to be aware of snow and ice buildup on roof tops.
