On September 25 2006, all eyes were on the Louisiana Superdome as the New Orleans Saints hosted the first professional football game there since Hurricane Katrina caused serious damage to the structure and its roof in late August 2005. The signature dome was repaired using an SPR spray-applied polyurethane roofing system from BaySystems, a marketing division of Bayer MaterialScience LLC.

"For years, the Superdome, like the French Quarter, has become synonymous with New Orleans," said Joe Stockdale, business manager for BaySystems.

"We're honored to play a role in this project, which symbolizes New Orleans' ongoing comeback from the devastation of Hurricane Katrina."

The project's scope was immense: The roof covers an area of 9-1/2 acres, and is 275 feet at its apex. But just as daunting was the time frame for the project, which needed to be completed within six months of the contract award to ensure the Superdome was ready prior to the Saints' first home game of the 2006-07 football season. BaySystems and Brazos Urethanes, the general contractor for this project, were up to the challenge. Material began shipping March 10, and less than 4-1/2 months later, on July 27, the project was completed.

The project entailed removing the damaged roof in sections measuring 40-feet-long by three-feet-wide. Each section was replaced with a new panel of the same size that had been sprayed with a seamless, leak-resistant layer of Bayseal closed-cell insulating foam. An elastomeric coating was then applied over the foam for further protection. Once the new panel was raised into place by a crane equipped with a special "cradle" it was welded into place. Once again, spray foam and a coating were applied.

This process was repeated 3,750 times.

After all sections had been welded in place, the roof was power washed to remove welding slag, and another coating layer was applied.

In addition to its excellent appearance, the new Superdome roof is designed to withstand almost anything Mother Nature can dish out: BaySystems offers a 10-year warranty from the date of completion for leaks and unlimited resistance to wind damage.

According to Stockdale, SPR spray foam systems from BaySystems have a proven track record for challenging roofing applications such as this, including the roof for the University of Louisiana at Lafayette's football stadium, located just 60 miles from New Orleans. "We have more than 30 years of proven performance in the roofing industry, with well over a billion square feet of SPF roofing applied in a wide range of environments" he explained.

BaySystems roofing systems provide durable, trouble-free performance in any climate and under any weather conditions, and with Underwriters Laboratories and Factory Mutual approvals, they can be used in new construction or applied over virtually any existing roof.
