I take it there isn't some magic composite decking which doesn't rot/mould/slip warp? Even if spendy? I want to do something and never deal with repairs again while I live here. Have been looking on youtube and building over the steps seems a possibility with some kind of stone-ish panels.
Trex composite decking is very durable.
Something similar should be available in UK.
Often used to build steps right on top of old damaged concrete steps.
Something like that will surely still get slippy when covered in moss/algae/rotten leaves though. Normal wooden decking will be fine if you keep it clean, and add those sandpaper-like grip strips.
