What does that say ?
Are you terminally stupid??
Obviously, councils waste money, doing replacement work which is completely unnecessary. They have a pot of money to allocate, or they miss out on it - so they spend it, need to or not. My roofer, whose opinion I trust, has said my original roof, will outlast, the ones which were replaced. They only have a double thickness of tile, versus my triple, so any tile failure means they potentially have a leak.
