At this condominium development, 90 of the condo deck patios are elevated over garage space. We have a good roof membrane placed over the wood deck, but many owners want to cover the membrane with outdoor carpet fully adhered to the deck. Problems develop later with rotting of the deck. What removable materials exist that would allow maintenance of the membrane, still look atractive. Ideas include pavers with drainage channels, interlocking carpet pieces, etc. Your recommendations would be helpful. Thank you.
