Challenge

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.

Solution

  • 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
