Most of the flat roof above the Drum Artz building in Toronto was useless space with no redeeming economic and environmental features. Then Avenue Road Roofing and Xero Flor volunteered to convert the drab flat roof into a beautiful green roof that provides wide ranging economic and environmental benefits. Some of the key steps in the transformation are shown in the pictures below.

Here is what the flat roof looked like before Avenue Road Roofing went to work.	Sasha Aguilera, Operations Manager for Xero Flor Green Roofing Systems confers with Craig Bennett, Deputy Executive Director for Avenue Road Roofing.
The new roofing, comprised of 2-ply modified bitumen membrane, was supplied by IKO industries.	Avenue Road Roofing workers bring in rolls of fleece that are installed to retain water.
After the root barrier (black material) is installed workers begin installing the drainage layer that moves excess water off the roof.	Finished installation of the drainage layer and water retention fleece.

The finished deck provides new living space for administrators, teachers and students.
