Oh I shall. As I said, it's a free country.

By the same token you are free play the secret squirrel with your
expert knowledge of ridge tiles.

Unlike you who seems to have to get someone in to do it anyway, I
don't claim to be an expert. Just observed how many roofs I see with
chunks of mortar missing from the ridge tiles.

I have not done ridge tiles but I have refitted a coping on parapet
walls.

The fact you can't see the difference between that and ridge tiles says a
great deal about your building knowledge. Bricks don't tend to move around
like the average tiled roof.


That's why I bothered to look for recommended mixes and found out
about the revised BS 5534.

Coping stones on a sloping parapet wall should be secured by more than
just mortar.

What have you DIY'd and what mix(es) did you use?

It also likely depends on what sort of roof you have and what the
ridge tiles are made of. But don't let facts gets in your way.

I'd be happy to consider any relevant facts you provide - like the ones
you quietly snipped from above.

Rather pointless with people like you who already know it all.


I know full well I'm not even out of kindergarten in the world of
building. And I try to be quick to admit my mistakes. But it'd be nice
to be told a bit more than that I'm just plain wrong. Eg:

where have I gone wrong in taking BS 5534 to apply to Victorian ridge tiles?

what mix is better?

who requires/recommends what fittings in addition to mortar for coping
stones on sloping parapet walls when the final section of wall and final
coping stone is horizontal (which is the arrangement on all the
Victorian terraces around here, as across much of London, with not even
a hip iron to be seen)?
