Cracks between sloped roof and exterior wall

Hello,

I have already done quite a bit of research on Google and know that this is a real hot topic.

Often, you have to seal these cracks yourself or the painter/fuguer uses joint tape (stretchable) so that when the material moves, the cracks are concealed as much as possible.

Sometimes, however, a contract explicitly excludes these "works"...

Our contract states that you yourself are responsible for "sealing" the "gaps between the sloping roof and the masonry".

But now the wall where the drywall panels of the sloping roof are attached is also made of wood. So not masonry. Does that perhaps give better chances for rectification?

The acceptance/key handover was over 2 months ago. The cracks started to form about 2 weeks ago.

We were of course informed that so-called settlement cracks could form and that there was no need to panic immediately.

The cracks look like this, are about 1mm wide, zigzag-shaped, and extend over the entire slope (1.80m), even past the windows. In all 4 rooms that end on the outer wall. This also includes bathrooms and bedrooms. Sometimes they are interrupted and between 30cm and 120cm long. They are still "growing."



Before I write a letter right away, I would rather first gather experience and information.

1.) Is this acceptable? Are the cracks (according to DIN) within the limits?

2.) The contractual clause "between sloping roof & masonry" then only applies to masonry, right?

3.) Is there perhaps a template letter for such "cracks"?

4.) Cracks are also forming in the plaster on the ground floor. At windows, doorways, and above the door to the terrace. Fortunately, these are not yet 1mm wide and (so far) only visible from a distance of about 1-2m.

Thanks in advance.

Hello, these cracks are normal according to our architect and will probably appear in a few other places over the next few months. Our builder specifically included in the contract that these cracks will be repaired under the warranty after 1 to 2 years. A masonry usually consists of stones, but here - at least for me - it is quite clear what is meant by that. Therefore, I see rather bad chances for you.

That should make everything clear anyway.
