House entrance with curved roof

Completely regardless of whether I like it or not - with a metal roof, I would definitely also think about how it is in the rain. It can get quite loud. If the bedroom window is right next to it, I would definitely come up with something else.

You will definitely stand out with the roof.

Good aspect - therefore thick sheet metal. Sounds like a glass roof.

we are "getting" new dormer windows. Because they are very flat, they will be covered with metal sheets. It will probably be titanium zinc. I also plan to use this material for the porch roof. Under the metal sheet is wood, and beneath that is a thick insulation (of course, for the porch roof only where and if an interior space is created). I don't know exactly what sits between the wood and the metal sheet—that will have to be determined by a roofer. A foil or a coating. This construction method is not a new invention and has been practiced for a long time. But our bedroom is not near the entrance. Getting a cost estimate for bending thicker (3 mm?) metal sheet might be interesting. That would also save some other costs.... How much quieter that would be is, of course, difficult to predict...

Hi

if it is supposed to look like in the pictures you will have to stretch it.
The wall is straight and the further it goes to the tip it falls off at the side.
You won’t get that on a rotary machine.

Another construction method would be to build like the wings of early airplanes. You pull, rivet, and hammer many smaller and larger thin aluminum sheets onto a wooden frame made of steam-bent wood (ash or hickory...) stretched. That can also have a very appealing appearance. Hm - not any less elaborate, I just realize.

Another design would be to build like the wings of older airplanes.

That's basically how I have been working for many years on many of my furniture and lamps.
