Help with grp to tile edge.

[Ash10010]

Hi, I'm not sure if I've done this detail correctly.
Should I be fiberglassing under the tiles or like what I've done? I tried to copy what was done on the previous felt roof. I'll be add the third row of tiles back against the lay board. Just a be concerned water is going to get under the grp at the edge of the tiles.

Thanks

Looks waterproof to me, I would probably add a lead strip about a metre long and 9" wide , to protect the joint between the fibre glass and those 3 tiles, apart from that it looks neat.

I need to buy some lead for the flashing on the other side and will have enough left to do what you suggested. Thanks for you help appreciated.

No. It’s a (future maintenance) nightmare.
The very bottom tile should have had a lead soaker attached so that the roof material could have been attached to the lead and not the tile. Similar for the courses above except the soaker would go under the tiles on a dedicated ply tray and onto the first tile.
It is unlikely to leak and you just need to hope no tiles ever break.

Yes this makes sense now, lead soakers would of been the way to do it. Should I cut back this fiberglass here to allow water to escape over the tile (Like what I've done with the above tiles)? Then cover all 3 tiles in lead, dressing it over the side to the flat root?
