Another photo, an area of the roof in between two dormers, they have installed "secret gutters" on the left and the right, but the plastic (and or the lead bit at the front) has pushed the tiles up resulting in this arrangement, which I do not think is right.

Any suggestions please?

PS: to answer my own question, the GRP secret gutter needs to go below the battens which must be cut a bit short of the side wall to allow the gutter to drop in. In my case there are rafters on either side against the side walls and cannot be cut, and so they placed the GRP gutters right on top, resulting in this situation.

My idea would be to remove the secret gutter, as it is pushing the tiles up, and place something over the tiles, not sure what.

Hmm yes you are right. The roofer, in his very broken English, did say it was the "lead" causing the issue. Here is another photo of another area, unfinished, and finished. Maybe the battens are too close to the side wall, and the lead also pushes the GRP secret gutter up, a combination of both resulting in this mess. What can I do?

PS: looking more at it I cannot have a secret gutter there because even if placed properly below the battens, at the front there will be a step to get over the remaining tiles...

I either make a lead soaker for each tile or use the GRP secret gutter (the one with the upstand) with the gutter that sits within batten level.

Have they used a GRP or a lead abutment soaker.

Theyve cut the battens short so they must’ve fixed a batten against the rafter to pick up the batten end.

It looks like it’s been correctly - they’ve used a secret gutter which is correct for interlocking tiles, rather than soakers.

Yes but I think a secret gutter has to drain somewhere, as the water channel sits below tile level, *if fitted correctly*. In my case, the GRP gutter had to be lifted so its mouth sits over the lead/tiles, and that kicks up all the other tiles as in the photo. I think they should not have fitted a secret gutter but something else over the tiles.

akist,

Its well wrong - you dont need any secret gutters in any of your pics.

In your situation you should use soakers that go under the tiles, and upstand 50mm against the abutment with a cover flashing dropping down.
Just like at any ordinary sloping abutment where slates or certain tiles are used.

Secret gutters are nothing but a constant source of trouble, & are to be avoided when at all possible.
eg. do you intend to clamber about your roof every couple of years clearing the secret gutters of moss & debris?

Its a simple matter to now remove the tiles and laths, and then set the battens & roof cover out correctly using under soakers.
The other difficulties could resolve if the roof cover was correct?
