price to replace whole roof

[GarforthHouseMews]

my semi-detached house in Garforth is over 100years old, no insulation or roof felt and some roten timbers which have lead to the roof dipping and leaking. whats a ball park price to take off the roof replace the shot timbers, felt, insulate and slate it all? the semi is about 15m long x 12m wide. There are rooms in the roof, cold bedrooms but original with fireplaces.
picture of rear (south) & gable end (west) of the roof. dipping is on front north side of the roof

Ball Park:

All in, including New Welsh Slate - around 25k
All in, including New imported or reclaimed slate - around 18k
Assuming the roof is approx 240m2

Thanks, I was guessing around 20K mark based on some old posts (2007) I read on here where comparisons were being made by members between Welsh/Spanish Villa Del Ray-Del Carmen/Random Green slates. Seems Welsh are the ones to use but also the most expensive.
I'll get some local quotes in nearer the time that I want the work done.
As the whole roof will be coming off I may make some changes to the appearance. I'll get a drawing submitted for Permitted Development to build up a wall on the gable end to extend the ridge across in a straight line to meet it creating more usuable space beneath the roof, and maybe add a couple of dormers with Juliet windows in that south facing roof (the road is to the north). Probably already up to the 30K mark now I guess :/ Will have to put the rents up
