Three scammers offered to re-mortar the edges of my roof tiles for a
reasonable sum.

While they were up there they lifted a ridge tile claiming the whole lot
were now loose and for a large sum would be prepared to redo them.
I declined, paid what had been agreed an they left.

Later I found the remains of what looks like the lifted tile. We now have a
bucket beneath a gaping whole in our roof.

I need to replace the ridge tile. The house was built in 1971. The tiles are
a dark bluish grey in colour and very heavy. I would guess made of concrete.

Without clambering up on the roof (I'm too old to that these days) it is
hard for me to be accurate about the size but from the fragments I would
say the sloping sides were something over 6 inches but the width of the top
I cannot say because the fragments do not match up.

Any clues about where to go to buy a replacement would be very welcome.
My location is NW London, near Watford.

Sadly these con merchants rely on the roof being beyond access for even
most DIYers.

An honest one these days will take pics of any problems using his phone
and show you what work needs doing (if you are interested)

Ordinary mortar isn't ideal for bedding ridge tiles as there will be
differential expansion between them and the main roof. But there are
flexible alternatives around. If you look at most roofs where ordinary
mortar has been used it will be cracked and often bits missing.

I'd ask neighbours if they have used anyone for this sort of job who was
good and honest.
