Roof penetration - heat pump pipes correct?

[WilliamÅberg]

Hello,

I would like to know what those of you who are more knowledgeable about this think of this roof penetration of the pipe from the heat pump. Light coming in through the small "gap" between the cladding and the pipe's penetration. You can see glimpses of the roofing felt and roof tiles.

House newly built, 2019. But have had minor issues with "sloppiness" in the construction from the company that built the house - or just plain bad luck. Is there a risk that moisture will penetrate here? Should it be sealed with some form of sealant if done correctly? Or is this sufficient? The attic is insulated with mineral wool.

Are there traces of water if you follow the pipe down where it goes into the insulation or whatever it is? If not, it hasn't leaked in 5 years so there's probably no point in trying to fix something that isn't a problem.

It leaked two years ago, then we had moisture that went down through a socket in the ceiling in the room directly below. It was because the "chimney" attached to the outside of the roof had been blown askew in a storm and needed to be replaced with a new one. During that time, moisture had made its way down through the pipe to the sheathing and insulation. They dried out with a fan.

But because of this, I'm very keen on making sure it's done correctly now. Sure, I can check if there's moisture under the insulation. Can you just move around in rock wool insulation with your hand, or should you use a glove? It has been sprayed in.

What does it look like from the outside?
