Is it paint or a membrane?

Is it paint or a membrane?

That is a great question that I don't know the answer to. Based on my very limited understanding of waterproofing, I would suspect it is some type of waterproof layered membrane designed to being water to the edges to be brought to somewhere else.

Membrane. This material looks to be either a TPO or PVC membrane, but it is impossible to tell by the pictures alone since both materials are white. Both of these materials are pretty standard for commercial roofing now. These roofs have the membrane on top, underlain by a roof board (the grey material), further underlain by an insulation layer.

I wonder if that's the final look or if there will be a further layer on the roof. Can't imagine it stays that clean looking for long.

Maybe a giant sponsor / naming rights logo to be slapped on in due course!

The white is not meant to stay clean, it is meant to reflect sunlight and improve thermal performance of the building. These roofs do indeed get dirty and need to be cleaned/maintained.
