Roof Tiling
- Thread starter whyme!

Yes, tiles can form the undercloak.
There should be a 38mm to 50mm overhang of undercloak.
The verge tiles should be double nailed.
If it suits, we set the verge tiles into the bedding mortar as we work up the roof.
It saves work & helps for a better job when pointing the wet verge.
The mix should be a little less than semi-dry. If its sloppy it will soon form cracks.
Unless a dry verge is used the batten ends of a plain tile roof will be subject to decay within a few years - but wet verges are traditional & look so much better.

Ideally the brick gable should have been cut a little lower to allow the tile undercloak to be bedded .
Im guessing the plan here is to point the joint and not bed..
Not the right way to use tiles as undercloak.
You might just get room to use slate (real Slate) and bed that.
Or you could use a CF undercloak strip and itll crack to buggery.

Neatly pointing narrow joints under the UC is not difficult.
Here it needs a bed of muck under the undercloak which is now going to be difficult to achieve using tiles.
It would be unfair to point the finger at the tilers, when the brick gable is a little to high.

OP,
I only speak for how I do this kind of verge.
You can see the felt below the undercloak tiles, this is its correct position.
IMO its not important to bed the undercloak tiles on to the felt.
The bedding mortar I'm referring to goes on top of the undercloak tiles.
Then the verge tiles are bedded into it.
Verge tiles are the very last tiles at the verge edge of each course.

So can this still be achieved after tiling rather than bedding each verge tile as you go?
Jamming the tiles under the batten dry is poor practice
The tile undercloak is bedded onto the brickwork not felt. it is then leveled up on the mortar bed.
As far as bedding the verge this can still be done no problem.
It doesn't need to be bedded as you go.
If its short verges then bed as you go is fine.
a long verge 60 + courses then do it in one go with associated verges and end ridge.

Again, with respect, I'm merely saying this is how we do it but I'm always interested in how others do jobs.
Not always but mostly, we find that its never best to point wet verges after fixing the verge tiles.
Pointing can push the S&C back on to the battens, & it doesn't guarantee to give full contact to surrounding surfaces.
We carry out bedding as we go, no matter how many courses go up the roof.
Its the same for repairs - lift & re-bed the verge, no matter what kind of tile is in-situ.
Felt must always be below the undercloak.
Its not always possible but battens should finish approx. 100mm from the verge edge.
AAMOI: there's no kicking up to be seen in the pic - what can be seen is on the same plane.

With respect, the way we do it is
bed the undercloak not jam it in.
Bed tiles to previously bedded undercloak and point in the same mortar.
on longer verges set tiles to undercloak un fixed at this point. carry on and tile roof until you are ready to bed the verges in pairs.
Try doing 180 course verge as you go.
There is no kicking on the tiles in the picture, but there is no room for a bed.
Jam the tiles in!!!! poor show
All practical experience ..not googling

Whoa, slow down, I made it clear that I wasn't criticising you - so why be so fragile & sensitive.
Read what I've written not what you think I've written - nowhere, for instance, do I suggest that its good practice to "jam the undercloak in".
I'd previously imagined that you were a working roofer, & I'm glad to hear you confirm it but why do you feel it necessary to even claim "practical experience"?
By the way, do you mean to say that you've stopped googling permanently or that you are not attempting to google while posting?

Whoa Slow Down! Read again what I wrote and not what you think I wrote.
I state jamming a tile in isn't good practice.. You said you do it!
Anything I answer on here is my own experience.
I just simply said I don't google answers like some do.
Anyway post has been answered.
Moving on

Give it a rest. Data is an experienced roofer (you can tell) so take it on the chin.
