ᐅ What is the approximate additional cost for a lower roof pitch?

Hello everyone,
According to the zoning plan, our roof (shed roof) must have a minimum slope of 15°.
We didn’t want more than that either, but the architect said 18° is actually the minimum that works.
Now, during the material selection phase, they suddenly talk about 22°. That is quite a lot.
We were told that with a special type of clay tile, we could manage 18°.
I did some research myself. Our standard roof tiles would be the Braas "Harzer Pfanne".
They are designed for a standard roof slope of 22°. Below that, the underlayment would probably need to be more waterproof.
Can someone give me an approximate idea of how much something like this would cost for a base area of 9m x 10m (30ft x 33ft)? When I ask the developer, I always wait many days or weeks for such information.
The developer would save money as well, since with a flatter roof there is less roof area and also fewer aerated concrete blocks and plaster are needed. I wanted to use this as an additional argument.
Even for increasing the roof overhang from 30cm to 50cm (12 inches to 20 inches), they charge 2,250, which I also find quite expensive for just a few centimeters.
Best regards and Merry Christmas

So maybe I wasn’t clear enough. The development plan requires a minimum roof pitch of 15 degrees. We want to have the roof as flat as possible. The architect said at least 18 degrees; otherwise, it would get too expensive, but the builder suddenly wants 22 degrees. However, the offer and the already approved building permit / planning permission state 18 degrees. So I don’t see why I should pay more for that. An offer is an offer. They should actually be familiar enough with their roof tiles. It’s just the standard tile we are using.

I don’t have to understand your architect – why would a roof pitch of 18° be cheaper than one with 15°? Especially since in the range of pitch 12–22° the same flat clay tiles can be used. I also don’t see higher costs for the masonry; you have to comply with the development plan anyway and you can adjust the knee wall so that it matches exactly.
You have a valid contract and an approved building permit / planning permission – I would say it is your provider’s problem if they don’t know their construction documents / contracts ... and changing from 18° to 22° is not possible without an amendment to the building permit / planning permission.
