Amherst company has the Metrodome covered; Birdair Inc. fabricates, installs new roof after deflation in December

The Metrodome has its roof back in time for preseason football, with help from an Amherst-based company.

Birdair Inc. served as the roofing subcontractor, fabricating and installing a new roof for the Minneapolis stadium on a five-month timeline that the company described as "aggressive."

A snow and ice storm had caused the roof to deflate in December 2010.

The company replaced the Metrodome's 10-acre roof with more than 700,000 square feet of fiberglass outer and liner membrane material.

"Birdair provided us with a new generation of roofing material that is stronger and adds more transparency for sunlight," said Steven C. Maki, director of facilities and engineering for the Metropolitan Sports Facilities Commission, in a statement.

The work began in March and was completed in July, ahead of schedule, Birdair said. Birdair built and installed the previous roof in the early 1980s.

The new roof -- a signature of the Minneapolis skyline -- looks like the old roof, but with a lower profile. The Vikings are scheduled to play a preseason game in the Metrodome on Aug. 27.

Birdair's corporate offices are in Amherst, but its manufacturing is outside the United States. It is a division of Japan-based Taiyo Kogyo Group.
