Making a few assumptions you’d need about 23,000 slates for 1/3 acre of roof. If you can get away with Spanish that’s maybe £35k. If it’s listed you’ll need Welsh so can double that.
Laying 250 a day and assuming out of London you’ve probably got £25k labour.
Then there’s stripping, disposal, timber repairs, ridges, leadwork etc, but even with all that you’re well under £200k for a brand new roof.
They’d be ok.

So don’t worry.
