I'm trying to find out what's the best decking for a flat roof terrace with a trocal finish. The area is approx 5.5m square and is suppprted by posi joists. I need something as maintenance free as possible which can sit on risers or pedestals which won't damage the trocal and will allow rainwater to drain off. I'm thinking of either natural stone paving slabs 20mm or 30mm thick or a composite decking. Any advice or suggestions would be appreciated.
Are you a tradesperson and able to answer this question?
