Hello,
We have a single-family house with a Berlin wave tile roof. The roof is now about 30 years old and urgently needs to be replaced, as the structure is no longer sufficient.
Unfortunately, due to weight restrictions, traditional roof tiles cannot be installed. The maximum weight allowed is around 15kg/m² (3.1 lbs/ft²).
Of course, there are alternatives to roof tiles, but I am not familiar with them. Does anyone have experience with any kind of lightweight roofing? It is especially important to me that the roof is not too noisy inside the house during rain, which might be an issue with metal roofs.
I look forward to your suggestions.
Best regards
Edit: As an example, we found something from Prefa that fits the weight requirement. However, I would appreciate it if someone has experience with these or other manufacturers.

what is included in that?The offer from Prefa is still pending.
This concerns an offer for the metal roof.
It includes:
roof panels, curved ridge caps, verge profiles, eaves flashings, ventilators, connection profiles, nails, lead-colored SK in red-brown, counter battens, battens, sheathing, Delta-Maxx+ with adhesive tape, ridge roll in red-brown, scaffolding, and disposal.
Plus a few smaller items.
As mentioned, for a 230 sqm (2,476 sq ft) area, the cost is about 26,000 euros.

Why exactly can the roof not be reinforced for standard tiles?Because the current roof can only support 15kg/m² (3.1 lbs/ft²). Adding additional load would likely be a very costly matter. Also, according to my information, the ceiling joists and the roof rafters are connected and form a single structure, which makes it very difficult to reinforce the entire system.

I can only recommend contacting several specialized companies. But in the specification, don’t fix the brand, only specify the maximum load of 15kg/m2 (3.07 psf).
I can’t imagine that they wouldn’t offer cheaper options.A roofer already came by before. He wanted 43,000 euros for a residential house (230m2 (2475 sq ft) area), garden shed (40m2 (430 sq ft)), and garage (40m2 (430 sq ft)).
And we’re not talking about an exclusive residential area (Munich, Hamburg, etc.), but a rural location.
