Around the same time we had all of the ridge-caps etc repointed, as the mortar was crumbling the guy who did it said in his opinion, this is all that needs to be done on a tile roof and basically the so called "sealing" does nothing and the painting of the tiles is purely for looks. He had worked for a roof restoration company previously. The freshly painted tile roofs look a bit unnatural to me.
PS GGG were ok, quite good actually but they only did gutters at that time.
That makes sense to me with a tiled roof.
Back in the 1980s I owned an attached cottage in Melbourne St, North Adelaide. There had been a few roof leaks above the common wall, and the guy who owned the other half had his galvanised iron replaced and wanted me to do the same as it was still leaking. I got an older roofing tradesman to look at it. His view - the old iron was overall good and stronger and better galvanised than the new, just a bit rusted on some edges, and the main cause of the leak was that the central gutter where the V met in the middle at the back just wasn't deep enough.
He replaced the gutter, cleaned the iron, sleeved it where needed, primed it with old fashioned paint on galv, then painted it. It cost a fraction of the two quotes for re-roofing. It never leaked again in the 5 years I was there, and last time I drove past [in 2003] it still hadn't been re-roofed.
