A ridge tile has fallen on to the flat roof can I put it back on with grip fill or do I need to chip away the old cement and fit it with new cement. Just thinking grip fill would be easier.

Gripfil.

cement has very little adhesive qualities, they're normally just sat
in place and pointed around, the cement acts as a stabiliser more than
anything




Mine have an embeded galvansied wire to embed itself into the cement. Seems
a good idea.

A couple of years ago a builder told me that he only charges £20 per ridge
tile. This is taking them down, clean up and putting back.

Neighbour's fence is in my garden and someone's wheelie bin went flying
down the road (why they put it out over 24 hours early when there was a
storm due, I don't really know).

Is gripfill good enough for an exposed roof?

I'd be tempted first of all, assuming I really wanted to go on my roof,
which I do not, that the first thing to do is check the rest of the times
and the cement fillets etc, after such a battering as otherwise there might
be more work to do.
I have been told that if my roof needs work to be sure to get a person who
has a proper roof ladder as on old roofs the underlying structure might not
take the work of an amateur clambering about on it.
There have been a lot of injuries and even deaths of people 'just putting
a ridge tile back'
As for kind of gluing it back, well temp repair, sure, but I'd not expect it
to last if you are e bonding it to cement that has already cracked once to
let the tile come off in the first place.

Hmm, well maybe but if that were the case then the water would get in far
more than it does, at least on my roof.

Will get a local builder in when the weather is better to check all the ridge tiles.Really just looking for a temporary seasonal fix.

I was a bit concerned about our ridge tiles seeing the winter through,
so I had a roofer take a look whilst he was fixing the chimney
flaunching. He said there is never a need to re-bed them, they just
re-point the edges without lifting them. He charged £70 for redoing
them all, end to end.

From the ground, our roofing man said they needed repointing (after 100
years) but on close inspection rebedded them. He wqas up there to replace
some dropped tikes.

Is this some arcane term I don't know, or have you been dropping
Yorkshiremen off your roof?

That was a waste of £70.

If they are loose, and just sitting on the mortar then a bad
storm with plenty of buffetting (violent up and down air
movements) then they could be dislodged.

Take them all off, remove the old mortar and give a good
scrub with a wire brush to remove any dust.

Ridge tiles need to be bedded in a very strong mortar mix
that adheres well to the tile.. This gives it added mass
to keep it in place.

I'm not convinced. It would need the wind to get under them, to lift
them off - repointed as they were, the wind cannot get under.

They were rebedded some 15 years ago, but not properly pointed at the
time. I had him round to reflaunch the chimney, as there were
indications below of obvious ingress. His reflaunching entirely fixed
that issue, but he pointed out at the same time, that the ridge needed
to be repointed, but he didn't have time to do it there and then. It
was obvious to me that it needed to be done, so I made arrangements for
him to return.

Sorry but this never is a great idea. If you re-point, there will only be a
very thin layer of mortar which will crack and fall away within a year or so.
Always re-bed and it will last for years and years.
