My intention was to create a By-Law to regulate the cost sharing between owner and Body Corporate, when cost sharing was appropriate.
That’s not what you said in your initial post. It’s not a “win-win” when one party has no need to fix anything in the first place.
In fact, if the membrane was already in need of repair, and the the tiles would need to be lifted to do so, then the entire cost – membrane and tile replacement – would fall to the owners corp.
