We are building a house with a developer and are close to the handover.
We noticed that there is about 4-6 cm (1.5-2.5 inches) of standing water on almost the entire surface of our garage roof. A gutter was installed behind the garage, and roofing felt was applied on the roof by the local roofer.
It is obvious that the rainwater cannot flow into the installed gutter because the surface slopes upward toward the end.
We raised this issue with our developer and were dismissed with the following response: Quote, "The roof is going to be greened anyway, or you can put gravel on it—then you won’t see the water. And when it rains enough, the highest point will be exceeded, and the rainwater will flow into the gutter."
We were very surprised by this reply and rather believe that there is a defect in the execution or in the purpose of the gutter, which currently is not fulfilling its function.
Furthermore, the contract states that the downpipe should be routed internally, which was not done. Regarding this point, our developer responded as follows: "During the construction process and coordination with the roofer, we decided on a gutter. Since this represents a minor deviation, we did not inform you."
BANG!!
Is anyone here able to help us? To clarify, I have attached a few pictures.
Thank you in advance for your responses!!

In der Ruine21 Dec 2023 06:30Standing water also freezes, which is not good for the roof.
If there is even a very small damage to the roofing membrane, standing water can penetrate for days instead of draining away immediately.
The only thing that comes to my mind is the following:

The only thing that comes to my mind is the following:
I personally always prefer an external gutter over an internal one. In the event of damage, internal gutters are usually more problematic.
However, to me (as a layperson) this looks poor— the pitch is simply incorrect.
A green roof is beneficial; it also protects the roofing membrane and, according to our roofer and general contractor, can at least double its lifespan. It’s also good for the microclimate and local insect life. But of course, it must be installed professionally (membrane, substrate, drainage, etc.).
Do you have professional construction supervision that communicates with the general contractor or builder on YOUR behalf? If not, it might be high time to find someone. No layperson can correctly identify and assess all defects. For that, you need experts. Building a house usually involves a significant amount of money, often the largest expense in one’s life. No one wants to take full responsibility for this as a construction novice alone...
