The roofing felt became too short, how to extend?

[swealp]

Hello!

The sillpapp became a little too short (1cm) on the outside of the facade.

I thought of extending it to be completely sure.

The idea is to push in about 4 cm of sillpapp from underneath and secure it with an L-aluminum angle.

What do you think? How else could one solve it?

Thank you very much.

The best way to solve it is by doing nothing. It's probably just destructive to try to insert syllpapp in there afterward.

The pappen is in a place where it is useful anyway. Additionally, it likely won't even be needed if everything else is fundamentally okay. So the syllpappen is really just a double safety measure. It doesn't have any real function.

The sill paper is supposed to protect against moisture that comes up from the concrete, right?

I have read some reports where old houses without sill paper have problems with moisture.

Thanks!

hmm.. not sure how to proceed really

But you already have syllpapp, the one cm that is outside is not against the concrete. Why should you do anything?

 

[Stefan1972]

yes but not that much moisture rises in the concrete, not even in old houses so if you read about someone who has had problems it's guaranteed to be due to something else fundamentally.

If at any weather condition it can condense against the windbreak, it would be foolish to have extra sill paper directing it into the wall construction.

Yes, it feels like there will be significantly more moisture running down during the next heavy rain than what is absorbed during the entire lifespan of the concrete slab.

Thank you for all the answers!

I had it explained by our K.A that it can flow in from above, just as you all said.

The best solution, said our carpenter, "is to lay asphalt from below."

So now they will apply hot asphalt from below to protect against any splashes, etc. that may occur when it rains from below.

Best regards

Is the "väggen" really visible and so exposed on normal houses then? Sounds very backwards all of it.

Hi Stefan!

It's like my sketch that I attached =)

Best regards

Yeah, I saw the drawing but I was thinking more that others might be able to give an idea of how it usually is? It sounds a bit far-fetched that you'd need to protect it in this way. That it would be so exposed?
