New build, few oddities

[ConfusedCheese]

Hiya. We recently moved into a new build property and I've noticed a couple of odd bits. With all the wind recently, I kept hearing a loud vvvvvvvvvvvvvvvv noise (best way i can describe!). I managed to track it down to the roof, and I'm pretty sure its right at the top of the ^. I'm assuming its probably just the lining vibrating? But I noticed this from outside:

I know the tiles are forticrete gemini... it looks to me like the one top tile is chipped and rather than replacing they've stuffed the hole with something? Should I be concerned by this?

From inside, I also noticed the entire top of the ^ is covered by lining apart from this one section. Is this anything to worry about?

Thanks for any help!

With the recent high winds we have all been getting you would be hard pushed to live in a house with a roof which didnt make a noise

Anyway the ridge roll under the chipped ridge tile is sitting up and that will make a noise, nothing to worry about.

The membrane should lap over the apex to prevent water ingress if you ever lost a ridge.

Ahh yeah I can see it a bit clearer now! Thanks for the reply. Any idea what the little bits sticking up are? Looks like something trapped underneath.

I have the roofers coming back to fix a chipped tile so may ask them to replace this one too while they're on the roof.

Its just a piece of the dry ridge fabric.

There should be a 1" gap on the underlay at the ridge.
As you have a dry ridge system fitted..

Sorry, please excuse my lack of knowledge in this area but I'm not sure if you're hinting something's wrong or not?

Shouldnt need vented ridge with breathable membrane..
