I am an intern at an architecture firm and have been working on a re-roofing job for the past couple of months. We have recently found out, from the interior, that one of the additions to the building has concrete decking. I am looking for details that show how slate can be attached to concrete. Any references or advice would be greatly appreciated.
Thanks
P.S. I am new to this site so if I'm doing something wrong please let me know.

Can you simply not just nail stone directly to concrete? What can go wrong?
Have you asked the senior staff in your office? They likely have standard references for you to consider.

Thanks for the reply,
I'm not sure if that will work but I am looking into it. As for my seniors, they're the ones who gave me the task. It's a rather small firm with only about 5 other architects.

first few images in a google search for slate roofing tiles on conc slab showed reasonable starting points.

Would not do that. Put a peel-and-stick self-healing waterproof membrane over concrete, place treated wood battens (2x2s)_ then nail the slate to battens. Min. roof slope should be 3 in 12.

You're installing slate, which is usually a steeply pitched roof. But then there is a section of the building with a concrete deck, which is usually not a steeply pitched thing. So, you're either telling us that someone built a steep slope concrete deck, or that you're trying to put slate shingles on a roof of insufficient slope.
I'm going to roll with the idea that you have a low slope concrete deck. If the Owner wants slate at this location, you could overbuild with trusses and then do the slate. And if this is what's happening, one of your coworkers has sent you on a wild goose chase. Can I interest you in going on a snipe hunt?

I just love the idea of a high pitched roof built up of concrete. It's like those lazy 1st year student projects all over again.

Mercer museum in PA, the first poured in place concrete building in the US, has what looks like a 12/12 pitch slab roof.

At what slope to slate shingles become slate pavers?

When you are able to walk on them (which you shouldn't do) without falling off.

Slate pavers or ballast over a composite deck + roof membrane, etc isn't all that uncommon...
OP, what is the slope of the roof you are trying to put slate on?

OP just said roof. Not pavers. If we're talking pavers, then we have a whole new can of worms to deal with, because the person isn't asking about an actual membrane at all.
