Need glue suggestions to repair concrete roof tile.

You could use epoxy, or just mix up some cement (not mortar) and water into a paste. The problem with the latter is that you have to stop it drying out while it cures (several days) but if you wet it too much it will be weak. For epoxy to work well you have to remove any loose powdery material from the surfaces to be joined.

car body filler.

How much is broken? Is it just a corner or is it almost half of it. I remember many years ago seeing somebody do this with a product by Dow Corning called Urethane Bond, if it still exists. It even glued asbestos. it was quite strong but not rigid..Very handy for terra cottsa concrete and the like as long as it was mostly ornamental or not under huge stresses. Not sure if you can still get it, its bound to be against some rule these days! Brian

I've had an iron bench stuck to concrete flags for several years. Gets all weathers and is still firm. I used Stixall:

Why not buy a new roof tile - they are only about £1 -£2 each tops.

Why faff about ? Scour the Builder's yards find one that's the same and replace . Whats the cost of one tile versus all the faffing with glues etc? Mind you has the roofing all weathered and a replacement tile would stick out like 't*ts on a bull'?

soup brought next idea :

A coating of yogurt will soon have it blending in.

Thanks for the replies. Think I'll give the Stixall a go.

FWIW I would have looked for a replacement tile first, then gone for epoxy but with a GRP patch on the back for reinforcement.

The concrete tiles I replaced had a brand name on the under side which made it easier to buy replacements. The corners on some of the tiles had broken off. I don't really know why.

Same here, the style is still manufactured, but the exact colour is no longer available (not much of an issue to me as the majority of the tile is covered by a zinc weathering slate).

A local builders yard that I know used to keep old stocks of the various tiles used on local estates, recently sold out to a big chain and got rid of their old stocks.

I did see some of the correct colour secondhand on eBay and Gumtree, but not locally and not selling in singles.

I strongly suspect that it doesn't - it doesn't even resist a bit of damp inside IME.

If it's anything like Pink Grip, I used some to glue the square caps onto fenc posts, so not exposed to direct sunshine and had some protection from rain - blown off by the wind!

and not going to pay £30+ on Amazon for the RT600. So is there an affo rdable UK roof tile glue? It's to glue on a corner off one tile that's some how got broken.

Why do you think car body filler would be better than Stixall for example?

Because experience has shown me that car body filler doesn't fail and all other 'sticks like s*it/polyurethane/epoxy' glues etc. do.

It's even better than epoxy as a general purpose stick almost anything to almost anything - the one exception being polythene and other olefins.

And it sets rock hard.

I had a tile which cracked right across the middle, and nothing matching is obtainable anymore. Decided to put lead underneath to make it waterproof, put the tile back in place, and the interlocking tiles stop the broken part being able to fall down the roof, which means it's practically invisible unless you know where to look.

Annoyingly, there had been a few spare tiles leaning against the back of the garden wall and brick gatepost when I moved in, but a some vehicle crashed into the gatepost, which resulted in the tiles and gatepost being smashed and ending up 10' up the driveway. I was away, but it must have done considerable damage to the vehicle. Neighbours thought it was a delivery van doing a 3-point turn.

I used 'No More Nails' on a clay tile- admittedly not on a roof. It has held up for 15 years or so. It is on a slope where a chimney changes size, a few feet from the ground. It isn't terribly exposed. I just glued the break and stuck some roofing felt on the back.
