Uneven underlay paper

[erikssonandreas]

Hello!
I am interested in a newly constructed property that is about to be for sale.

I passed by the house to take a look and immediately noticed that the underlay paper is not laid evenly. It's quite creased, see the picture.

When battens are then nailed on and the paper is pressed down, it feels like there might be sharp creases, which could potentially cause the paper to crack?

What do you think about this? Is it common to do it this way? Or surely the paper should be even?

Is the paper placed directly on the roof trusses? What are they supposed to put on next?

 

[Stefan N]

Guess they're using 2x3" directly and tiles on that, the cheapest solution.

Is the tar paper placed directly on the rafters? What are they going to do afterwards?

It certainly looks like the tar paper is placed directly on the rafters.

It's a Myresjöhus.

it is not an uncommon solution to replace råsponten with walk-on-safe fabric, then the result becomes like this.
Then there are battens and tiles on top of it.

A cheap solution, simply.

I guess they are using 2x3" directly with panels on that, the cheapest solution.

Is that common? So, there is no raw paneling on the rafters?

 

[Jonatan79]

I didn't know that it's approved to use roofing felt instead of a tarpaulin?!

it is not an unusual solution to replace råspont with a tear-resistant tarpaulin, then the result is like this.

Ok, thank you for the answer!

Maybe it is a tarp, my experiences are limited so I might be mixing up terms. I just assumed one uses felt.

 

[Jonatan79]

It might be tarp, my experiences are limited so maybe I'm mixing up terms. I just assumed you have tar paper

As far as I know, the tarps aren't black and are somewhat or much wider than tar paper. I'm saying you should carefully check what materials have been used. Whether it's correct or not, it's a frugal Småland solution

As far as I know, the tarps aren't black and are slightly or much wider than paper. I suggest you look closely at what materials have been used. Regardless of whether it is correct or not, it's a thrifty Småländska solution

Common and common, it's not an uncommon method for cheap houses.
It absolutely works, so there's no need to worry about that, but at the same time, you should know what you're buying and pay accordingly.

If they make such a cheap solution on the roof, I would personally assume it's a consistent theme for that house.

The fabric comes in several colors depending on the supplier.

The membrane comes in several colors depending on the supplier.

Hmmm. The roof membranes I find start at 1360mm wide and up. If they cheat and use regular underlayment felt, that's less good...hard to see in the picture.

There are as narrow as 1m at least, and with a 15cm overlap they become quite narrow, but I can't say what they have used. I seem to remember that the bmi group has had fully black ones, but I'm not sure.

 

[ralvejd]

Hmm, even I, who have never laid paper before, don't manage to do it so badly when I lay it alone at 45 degrees.

 

[Aunty]

Available down to 1m in any case, and with a 15cm overlap, they become quite narrow, but I can't say what they've used. I recall that the bmi group has had completely black ones, but I'm not sure.

exists, as mentioned, in all possible sizes and colors. it could also be a foreign supplier that has a self-manufactured one, and there's nothing wrong with that.
