Dry ridge system membrane not waterproof. Surely rain can get in through the plastic spacers?

[lozcozard]

New to dry ridge system. Put the plastic bracket/spacer in between tiles, put the clips in. It’s quite a large gap between tiles. I thought surely heavy rain and wind could force water over the edge of the plastic bracket. I thought that’s fine, the “waterproof” membrane then takes it down over the tiles. But it’s not waterproof!? It’s like a fine metal mesh that lets through water.

So therefore I’m relying on rain not being blown through the gaps of the tiles and over the plastic bracket. Is that right?

What’s the point of the membrane if not water proof?

Take all the ridge off and see how much water gets through....
The ridge is the least vulnerable part of a roof.

What dry ridge kit did you buy?

I have a membrane over the top so it’s just the batten that would get wet so just thinking of rot.

I’m going to put a waterproof membrane u see the brackets just in case I can’t think of a disadvantage having it under them.

Have you tied getting water on it? Does it go straight through?. Doesn't seem right to me...
You could put roofing membrane on top of the ridge batten?

Yes I sprayed water on because I could see it’s just a metal mesh and it drips through. Just seems stupid to me why it wouldn’t be waterproof. I’m not sure what function it serves other than stopping most water and just letting some through.

I’ve put strips of water proof membrane under the plastic joints just in case m. It’s only a front door canopy but this stuff is used in house roofs. I guess it must not let water through but I’m not convinced.

You could always contact the makers of easy trim and share your concern , I wonder if they did any testing.

Eh? There should be a sticky edged membrane coving the the gap between the top courses of tiles. Have you fitted it correctly?

I looks more like a bug guard. The plastic bits that go between the ridges look like they tuck under and would divert water away?
