Tiling over roofing paper? Suggestions
I am in the process of renovating an apartment, which has a substantial amount of outdoor space. Here are the basic facts: The apartment is on the second floor. The previous owner added a cellar extension to the building. The roof of that cellar extension is also a deck/patio for my apartment. The roof of the extension is concrete. It started to leak years ago and the concrete was covered with tar and roofing paper. I would like to tile over a large section. Is there any reason I can't use wire mesh and thin set to go over the roofing paper? How secure does the wire mesh need to be to the ground underneath it. I am pretty sure I could staple the wire mesh to the roofing paper, but it clearly can't be stapled to the concrete under the paper. Would I need to anchor the mesh into the concrete? Any suggestions would be greatly appreciated. Thanks.

Without anchoring the wire mesh, your tile job will start to wiggle over time, as heat and cold cause things to change dimensions. I would anchor the mesh using whatever is used in the industry for that purpose, to avoid a perpetual task of re-grouting tile joints.

no exterior tile in ny unless you want your tile grout to crack from infiltrating water which will turn to ice,,, where'd you get this idea, anyway ? 
it only looks nice in magazines which show homes in fl, ca, az, & nm,,, we made a decent living removing tile from augusta ( ga ) decks & restoring the underlying concrete.
better you should find a traffic resistant membrane & use adhesive to hold it in place,,, we just finished a deck using ' duradek ' - it seems like a good product [ no $ interest ]

Yeah, I can't see any way a walk on tile surface would work here. Many other options would be better.

if you're bound & determined to do that, put some pavers in place & build a perimeter frame out of p/t'd or cedar/redwood 2x4's,,, @ least you'll have a place to put your tushie,,, your also stand a better chance of not destroying what obviously was a failed ignorant attempt to repair a leaking concrete slab by someone else,,, don't compound the error by following your action plan
