Ask your QuestionGood day. I have a rooftop patio off of my kitchen on my third floor apartment. I recently removed the old decking to find the roof (normal flat, black, felt? apartment building roofing) is in fine shape--thankfully. Now, I'd like to install exterior ceramic/porcelain tiles. Can I put adhesive right on the roofing, or do I need a cement substrate first? The slope is already well structured towards the drain and so I'd like to avoid using self-leveler/skreed if possible? Thanks in advance for any guidance.
Asked by George on 18th Jan 2021"Hi you would need to prime the area first then tank it and then you can tile using a normal flexible tile adhesive with a flexible grout
Hope this helps
Many thanks

"Hi.
You would need waterproofing/tanking and laying down decoupling / antifracture membrane ( recomended Schlutter ditra 25, durabase CI++, Bal, Tilemaster antifracture mat), then tiling ,using S2 type flexible adhesive and a flexible grout.
Jobe done!"
