Hello, I am in the process of making an extension. I am sitting here contemplating how to solve my problem. I have received a truss design proposal.
The extension will be built on the gable side of the house, and there we have 2 windows on the upper floor with 3670mm from the metal flashing to the floor (concrete).
The size will be 6.5x10m. I can't get a proper slope on the roof, does anyone know if this slope is okay? Is it even okay with a metal roof on this?
I would like at least 14-16 degrees. Is it even possible to achieve with such a low height?
Hello! You can probably get better answers than mine on this question. But I thought I'd give it a try anyway since this forum always helps me so well!
Metal roofs work well with the slope. The maximum slope is usually listed on the sellers' websites. So you know that what you buy can handle the slope. But double-lock seam metal roofs can handle lower slopes than yours.
Can't you look at glulam, about 90*405 mm, then you can slope the roof in the other direction like out to the other gable or straight from the gable itself.

Sheet metal roofing works well at the inclination. It usually states the maximum inclination on sellers' websites. So you know that what you buy handles the inclination. But double-lock seam sheet metal handles lower inclinations than yours.
Then I usually check the träguiden:

Hope it can be of some help!
Thanks for the answer! I'm trying to find a sheet that is a tile imitation but they apparently require 14`degrees too!

It is absolutely an option, but it will be the last resort, as I have been granted a building permit with the current idea. The measurement was not exact when I submitted it.

Thanks for the tip!
You can always submit a change if you have to do it differently, that way you don't have to apply for new building permission but change the one you submitted.
The other day I was thinking about a new solution to my problem, and I came up with this idea, what do you think about this? This way I get the height past the window. But is it aesthetically right? The small roof will be wide enough so that the window can be opened. The ridge of the small roof ends up just below the rear window approximately. The first thought is snow, will it work?
Oh, I would have chosen the rooftop terrace if there are nice sun conditions and suitable rooms behind it.
Or a hipped roof! So the highest point of the roof is in the middle closest to the existing facade. And then it slopes down on three sides. I think that fits well with a low-pitched gable roof.
Unfortunately, a rooftop terrace is not possible, as we have neighbors right behind the garage and to the right of the garage. Since I am building closer than 4m to the property line, I don't think the neighbors would agree to it haha!

Haha, dang! But then you might have come "too close" emotionally as well
Then perhaps it is better to break it off completely with a shed roof instead. But it sure would be cool with a terrace on the garage roof
Break off with roofing material too, almost the same looks a bit strange

I'll have to check if a shed roof is possible. But I suspect it needs the same height. We only have 3670mm to the window sill and the garage will be about 6500mm wide.
Hmm, don't know if I misunderstood something now since I got such a different number...BUT
If you initially thought that the trusses would be placed as in your existing house (same direction); but to avoid it becoming too high so that the windows on the upper floor are not covered, could it not be like this with the slope:
I don't think the slope will be much of a problem on the drawing, but the only thing that strikes me is that the underlay looks flimsy. In my mind, it should be quite sturdy if you consider that the snow might stay on the roof. Now it feels more like it's assumed that everything always slides off immediately and the roof truss supports itself and the roof only. Maybe even borderline. But I'm not a designer, I should say, and you can't see all the measurements fully on the drawing either.
