Metrodome rises again in Minneapolis

  • NEW: Crews inflate the Minneapolis dome's roof
  • The roof collapsed during a winter storm last season
  • Crews have replaced it with new material

(CNN) -- Seven months after it went poof during a winter storm, the roof of the Metrodome in Minneapolis rose again Wednesday, with crews completing the process in about two hours.

The dome was fully convex about 9 a.m. CT (10 a.m. ET). Workers could be seen walking around the edge of the roof, tamping it down in spots.

On December 12, 2010, massive amounts of snow caused some roof panels for the 64,000-seat facility to "deflate." Video captured snow falling onto the field.

The collapse put the Metrodome out of business until the lengthy repairs and improvements could be done. Officials hope to have the $22 million project completed by August for Minnesota Vikings preseason football.

The collapsed roof played havoc with the Vikings' 2010-11 season, causing them to relocate their last two home games, both losses.

The roof's new material is said to be stronger than steel, with a flatter profile for wind resistance, CNN Minneapolis-St. Paul affiliate KARE reported Tuesday.

Baffles will help with acoustics, to a degree.

"It'll still be the noisiest football stadium in the NFL," said Bill Lester, executive director of the Metropolitan Sports Facilities Commission, owner and operator of the facility. "I suspect before the first kickoff people will notice that."

The stadium's full name is the Hubert H. Humphrey Metrodome.
