Are you one who doesn't get a few quotes before having any such work
done? And then chooses the lowest price from an obvious cowboy? Other
have more sense...

Oddly, many don't

True. Andrew obviously being one of those.

Plenty of unsuspecting homeowners have been caught out this way,
and I suspect some don't even know that their original slates
could have been re-used on their own house.

And just who said the roof being replaced used slates? Mine had what
was called double pan tiles.

Repairing an original slate roof using matching tiles can be very
costly.

if the damage is extensive. Mostly it's not.

The subject was a replacement roof, not repairs.

You may not even be able to find a decent match. Early slate roofs had
no felt, so have to be stripped totally.

You may also want to add decent controlled ventilation for the roof -
especially where insulation has been added.
