Can I ‘stick’ the Pavers onto my roofing membrane?

In our opinion this is not best practice. We would strongly advise against adhering any sort of paving or tiling directly onto a waterproof membrane.

In the past this practice was quite common, however over time it has proven not to be a sound solution as the waterproof membrane and paving/tile expand at different rates in hot and cold temperatures. Eventually they separate and often compromise the waterproof membrane in the process. Not good!
