Looked at a very large garage today. What kind of roof is this? Anything to look for as far as issues with it?

The outside is a flat rubber roof which I assume is directly above this stuff here in the pics.

It could be concrete, could be a gypsum product, could also be tectum. In any case, might want to have it tested for asbestos. I would say that the EPDM (rubber roof) is an overlay of a hot applied roof system right to that deck. At best you might have 2 roof systems on it, worse case is multiple roof systems over that deck.

It looks similar in configuration to a product I've used called Litedeck although it appears to be some kind of concrete composite panel whereas LiteDeck is an ICF panel made of foam and steel. The panels rest on the lower flange of the steel roof beams and in my case, support a cast in place concrete slab that covers the top flange of the beams.

I don't think it's Tectum, but what ever it is, it's been wet. I'd also be concerned it has any ACMs in it.
