Why would properly T-111 need replacing? It's just plywood with groves cut
in it.

Yeah. But I have replaced a lot of the stuff on several homes due to home
owners not keeping it properly painted and termites. This is particularily
bad in humid climates and especially if shaded by bushes.

That said, many sheds often do not get much attention after being built.
