Roof drainage. Lifespan

[bjojo]

Hello. My house is 11 years old and the roof drainage looks like this. Is it reasonable? Shouldn't it last better?

Much of what is visible can probably be washed away. Otherwise, it is probably completely normal. It looks like the wrong screw was used for the attachment to the svep, which has worsened things a bit.

Is it Aluzinc?
I believe we have a tinsmith here with a fantastic name who can say a thing or two about that material.

I believe we have a sheet metal worker here with a fantastic name who can say a thing or two about that material.

May I guess that it is felt on the roof?
Yes, aluzinc is not the best material...
But it's hardly around anymore...
