Without a long history of the various works on our roof, I am looking for a sort of band-aid to keep the tiles on! We have a 1930s house with original roof. It has shed occasional tiles for the last few years but now following the windy weather there are a couple that keeping falling off. I am told by the roofer that the it is a boarded roof and that the ridges the tiles hang on have broken/rotted so there is nothing to hold the tiles up when replaced other than friction. They have tried a bit of cement but that didn't work. I think we are heading for a new roof but I am trying to delay that decision as long as possible as we are considering moving or building an extension to get extra space. Does anyone know any method that would hold these tiles on a bit longer? Is there any sort of mastic that would stick them down? I have been told about some treatment to spray the entire roof with glue? I am appealing to the PH knowledge base for help and guidance. Thanks!

Don't have the roof sprayed with glue.

CT1 sticks pretty much anything to anything as a temporary bodge.

Sounds like you know the proper remedy though. New roof time.

No More Nails would probably do, but you need it all to be nice and dry first.

And are they the same tiles that keep coming off, or are they just at random, in which case you’d need to glue every tile.....

Either strip the tiles and get some batten under to fix or hang them off or new roof time.

Thanks for the replies so far - much appreciated.

I am going to get some CT1 from Amazon - might do the job and at £12 nothing much to lose!
I don't think NoMoreNails would do - roof damp most of the time in winter.
Taking tiles off and refitting battens might turn into a very big job

And yes - I realise we are looking towards new roof - just trying to fix to give time to make life-changing decisions!
Any idea what a new roof would cost?

Surely you can strip a small section where they're slipping and replace the rotten battens? Much better than a bodge with CT1 and probably work out cheaper as you won't do many tiles to a tube.

it might sound like a bodge, but i had a slipped tile on a bay window roof about a year ago. Wasn't in a position to get a roofer in at the time, but had a tube of evostick 'sticks like s**t'. It's like no nails but dries rubbery. I put massive blob on and wedged the tile in place and it hasn't budged since.

For what it's worth, I do intend to get a new roof fitted in the not too distant future and needed a quick fix at the time. It just happens to have held up for nearly 18 months now

Roof measures about 10mx14m at maximum width-length. Sort of T shaped with a gable at back - not really sure how to describe it. I have some drawings somewhere - location Rickmansworth, Hertfordshire

My last house, built in 1938, had close fixed feather edged board for battens supporting clay tiles and the boards gradually grew softer and softer. However what finally did for the roof was the nails in the boards corroded through and because the thin edges of the boards were soft, the whole flank of the roof (hipped) began to slide down the rafters. It was only the weather side that needed fixing so I got a roofer to strip it off and put modern sarking felt on the rafters and new battens, and finally use the old tiles to finish the job. The dearest part was the scaffolding. I forget the cost but it had been getting worse for about three years and I couldn't persuade the roofer that it was as bad as it was. More than five years ago and as far as I know it's been fine.

It would appear that using a mastic (particularly with slates) is now deemed acceptable by (SOME) tradesmen.
I was initially sold on it by a roofer but a couple of points:
- you need to use the correct one something like CT1 which is rubber / latex / silicon content is good for strength and flexibility
- watch that you don't use so much mastic that it creates a ledge for water to not properly shed from under the leading edge of the tile, it will back up under the tile and create a leak.
- the surfaces must be clean, dry and have no loose material on them such as dust etc.

A roofer replaced a handful of slates on out roof with this method and its ok, its easier that a lead strip or wire spring and cheaper and quicker but 2 slates are down already because they never cleaned them first!

Agreed - although someone suggested some sort of glue to treat the entire roof which would help retain the tiles and apparently makes the roof look very smart. We are in Rickmansworth - SW Herts - near Watford......

If they are plain tile, they should have nail holes in them. Could be with or without nibs.

If your roof is close boarded, get longer clout nails and spike them in, backed up by a blob of roof/gutter sealant.

A bodge, but you’ll get some life from it.

Anyone got any guide price as to how much it would cost to replace this roof?

Bringing to the top. Roof problems continue and looks like a new roof the best way ahead. What brought this to a head is that there are 3 short flat tops over bathroom and bedroom windows that are leaking and lead covering cracked. Fairly major job to repair I am told as it means taking off sections of tiles and reboarding etc. Also some of the battens that hang the tiles are rotten so need replacing anyway plus we are continually shedding tiles and having them replaced. I guess a problem with a 100 year old house. Have been quoted about £15K to replace - does this sound about right?
