The Metropolitan Sports Facilities Commission will meet today and, according to a good source, is expected to hear the evaluation from engineers that a complete new roof is needed for the Metrodome at a cost of $18 million.

A go-ahead vote for a new roof by the governing group of the Metrodome will be necessary if the stadium is to be ready for the Vikings' exhibition opener and all other events scheduled in mid-August. The Dome's air-supported roof collapsed during the Dec. 11-12 blizzard.

Originally four panels were damaged by weather. A fifth was deliberately opened with a shotgun to relieve pressure from accumulated snow and ice.

The engineering firms that have been evaluating the project are expected to report that replacing, and not repairing, the roof is the only way to solve the problem.

The Metropolitan Sports Facilities Commission has insurance to cover the cost of the replacement roof.

Vikings expect to play Meanwhile, the Vikings have sent out invoices to season ticket holders with the presumption that the Metrodome will be available for the two home exhibition games in August.

For the second time in three years, the Vikings didn't raise the price of season tickets.

The Vikings, like the Metropolitan Sports Facilities Commission, have interruptible insurance that they expect will help them pay for about 15,000 fans who asked for ticket refunds for the Dec. 20 Bears game played at TCF Bank Stadium.

With tickets costing from $29 to $128, or an average of about $70, the amount that will be refunded or credited to season ticket holders for the 2011 season will be around $1 million.

With the Giants home game being moved to Detroit and the Bears game being held at smaller TCF Bank Stadium, the Vikings' 2010 attendance was 470,009, compared to 510,203 in 2009 when all games were played in the Metrodome.

The average gross ticket sales for Vikings games at the Metrodome in 2010 before the roof collapsed was more than$5 million, before the big losses for the Giants game in Detroit and the limited-seating Bears game at TCF Bank Stadium. So at an average of $70 per ticket, the Vikings' income from ticket sales was more than $6 million in 2010.
