Dry Ridge System or Mortar?

[JayN]

My 1971 Marley Modern ridge tiles and mortar have come to the end of their lives and in the Spring I'll either be bedding new ridge tiles with mortar or doing it the dry way. I'll decide when I see what's under the ridge tiles, what kind of a batten system I have under there.

I watched a bunch of videos on dry system and my question is, when the adhesive membrane is rolled on top, then the tile placed on top and attached with a plastic union which is screwed (with a holding clip) onto the batten running under the membrane . Obviously the union is not waterproof, rain goes through then runs down from under the tile. But what about that screw through the membrane? Is there a risk of a water leak? Thanks.

The unions are waterproof if fitted correctly, and the screws have a rubber washer.

Thanks, so it seems, I found a video which clearly shows this. I think I'll go with this dry system, requires a bit more praparation time with battens and brackets but the actual laying the tiles seems much faster.

We have gone fully dry now with all our ridge, hips and verge. It's just so much simpler.

So I currently have the Marley non-half round modern ridge, the one with the angular shape. Marley's kit for this is very expensive so I'll used half round tiles instead so I can buy a more affordable kit.
Should I worry about the size of the ridge tiles or are these systems really "universal"? I am thinking Easytrim Ridge F system. I guess I don't even have to use Marley at all.

I need to check the loft in case I have an old-fashioned ridge board in which case installing the brackets will be a doddle.

We used the Manthorpe (universal) for these. Piece of cake.......
