The existing 25-year-old PVC single-ply roof on this building's signature dome was past its useful service life and the 4-ply built-up, gravel-surfaced system on its flat areas needed replacement. The building owners were seeking a solution that would not only match the original aesthetics, but that could also help them meet their environmental objectives.


  • A torch-applied two-ply SBS-modified bitumen Paradiene Roof Membrane was chosen as the durable solution that would maintain this roof's iconic status for years into the future
  • Meeting the owners' environmental goals, a Siplast Eco-Activ® cap sheet with Noxite granules was specified to help clean Toronto's urban air by neutralizing harmful nitrous oxides

Siplast Engineered Roof Systems have been applied in the extremely varied weather conditions of more than 40 countries.
