The nightmare of premature roof failure is enough to keep facility managers and building owners up at night. With so many roofing membrane options in today’s marketplace, many of which have less than stellar reputations, the commercial roofing industry is full of uncertainty. There’s still one constant, however, and that’s the proven performance of Sarnafil membranes from Sika.

Way back in 1985, a Sarnafil roofing membrane was proposed for use on an ambitious new project in Toronto: a design/build job from Ellis-Don Limited and the Robbie/Adjeleian/Norr Consortium. This plan called for a new stadium in Ontario’s provincial capital, a futuristic arena that would be known as SkyDome.

Completed four years later in 1989, the SkyDome entertainment complex became the world’s first stadium with a fully retractable roof.

“Our Sarnafil S327 membrane was proposed, incorporating a unique mechanically-fastened design specifically engineered for the dome project,” Mike Read told Canadian Roofing Contractor in July of 1989. At the time, Read was the General Manager of Sarnafil Canada.

“Extensive research was undertaken to validate the system that we recommended,” Read went on to say. “The project was, without question, the most technically demanding of any that we have experienced in Canada – or for that matter, internationally.”

Today, SkyDome is known as the Rogers Centre, but its technological achievement has not waned. The stadium continues to be one of Toronto’s top three tourist attractions and a model for architects of domed stadiums currently being built around the world.

In 2016, this world-famous landmark and its Sarnafil roof will celebrate a 27th birthday. It will be yet another milestone in Sarnafil’s storied tradition of proven performance.

Happy birthday to the Rogers Centre!

Some interesting facts about the Rogers Centre roof:

  • The roof covers eight acres and spans 674 feet at its widest point.

  • It’s large enough to cover a 32-home subdivision.

  • A 31-story apartment building could be erected in center field, and it would still fit under the roof.

  • When the roof is in the retracted position, 100 percent of the field and 91 percent of the seating area is uncovered.

  • The immense size of the roof sections (which are known as “roof panels”) is reflected in the following statistics:

  1. Panel One has 1,346 tons of structural steel and 22 bogies (roof movement mechanisms)
  2. Panel Two features 1,906 tons of structural steel mounted on 16 bogies
  3. Panel Three has 1,658 tons of structural steel, also mounted on 16 bogies
  4. Panel Four (the fixed panel) has 1,438 tons of structural steel and 20 bearing points
