This balcony floor looked fine from above… until we started peeling it apart.
Under the tile flooring, the only thing protecting the sheeting was house wrap and cement board. Tile is not a waterproofing system by itself, so water had been getting through and rotting the balcony floor underneath. By the time we opened it up, the sheeting was gone and even the supporting beam had to be replaced.
This is why exterior balconies, decks, and covered areas need the right waterproofing details — not just materials stacked together and covered up.
