Hello everyone,
we are currently planning our house and will build a single-pitch roof with a 6-degree slope. We have already received a few offers, but we are quite uncertain about what would be the best option.
On one hand, we are concerned that it might be too noisy when it rains, and on the other hand, that it could get too hot in the summer. Some people have also advised us against a metal roof, mentioning issues like screws rusting, metal warping, and so on. Others say such a roof only lasts about 10 years.
We were offered a trapezoidal metal sheet roof with anti-drumming features, as well as a standing seam metal roof.
What would you do? Are there any points a non-expert can consider to make the right choice?
Thank you very much for your help

Hello
We are building with a 5° pitch and have chosen a bitumen waterproofing with extensive green roofing. Other waterproofing options were excluded, even though they would have been workable for me.
Standing seam – roof pitch
Kalzip and trapezoidal sheet metal – penetrations are difficult, appearance of ridge, eaves, and verge not appealing.
The planned construction is as follows:
Gypsum board 12 mm (0.5 inches)
Insulated installation space 60 mm (2.4 inches)
OSB 18 mm (0.7 inches)
Insulated rafters 300 mm (12 inches)
Wood fiber insulation board 60 mm (2.4 inches)
Air layer 40 mm (1.6 inches)
Cladding 21 mm (0.8 inches)
Bitumen waterproofing
