Hello everyone!
I have written previously about leakage from the roof where it drips in during heavy rainstorms combined with wind.
I am a bit curious about roof construction in this forum. Our house was built in the '80s.
The roof itself, where the battens and counter battens are placed, is some form of masonite laid overlapping each other.
I was out last night and shone a light up through the eaves boards and I see that there are several PVC pipes about 60cm apart that come out from the roof, i.e., you can see them through the insect mesh from the eaves boards. Does anyone in this forum know why such pipes are used in roof construction, or is it a shoddy construction? It should be added that abundant foam sealant seems to have been used around the pipes to keep them in place.
I will loosen the eaves boards to take photos so you probably understand better what I mean.
Best regards,
/Fredrik
P.S. I apologize if the post is confusing

Yes, it's a bit difficult to understand
Are the pipes running along the roof slope, or along the roof ridge?
Diameter of the pipes?
Could they be spacers to create an air gap?
I'm just as lost as you.

Yes, it was complicated😄
The pipes are located along the bottom of the roof slope
The diameter of the pipes is about 5 cm
I also thought they could be spacers

Some pictures😃
Could the purpose be ventilation?
It seems so. Could you see the images?
Yes, I see the images. The view on how much an attic should be ventilated has varied over the years. Your solution seems to aim for a very low ventilation flow. Do you have vents in the ridge?Fredrik enström said:
Haven't been up to see it yet. Going to go up and check.
I suspect it's an afterthought made by a happy amateur.
It doesn't look very professional with all that plastic foam.
Someone thought there was too much ventilation and wanted to limit it, but not stop it completely.
So the pipes just go through a couple of decimeters where the wall and ceiling meet?
What kind of foam is it anyway? I've never seen that color myself.
PU foam is usually yellow.

The foam usually looks like that over time.
I only see the ends of the pipes so I don't know what it looks like further up. Going up on the ridge this weekend😄
Thanks for all the tips and ideas

Does it?Bob_the_builder said:
Not for me. It's yellow after five years, except where it's exposed to UV light where it darkens to brown.
That looks like entrecote roughly.
(Or are the colors wrong on my screen
)It's a dark place where my "entrecote" foam is😄

On my phone, the foam has the same color as bloodpalten in Emil i Lönneberga
Seems very strange. You can never have too much ventilation in an attic. You should probably examine it carefully. I would have removed it and made sure there is a clear path for the air.
