Tiled roof underfelt & batten replacement

[geoffm1066]

Hi
I've notice that from within the attic space the under felt circa 1980 has deteriorated and needs replacing, the roof is tiled with Redland 49s, it is a two story house up and over approx. 50m2 of tiled roof area so what price would I be looking at for scaffold front & rear, strip off tiles, batten and felt, supply & fit new felt and battens and replace tiles.
I would expect some damaged tiles and new ridge tiles to be replaced.
South east coastal region.

Thanks for looking

Geoff
