Building a small shed for pool equipment, and based on the ceiling height, I would like to build the roof from 44x70, which is admittedly quite weak, but does anyone with expertise have an idea of approximately how well it would hold up?
The shed measures 2 meters in width and 1.3 meters in depth. The rafters would have a span of 1.3 meters and I can set them closely together. On top, tongue and groove boards are planned, with felt and metal sheeting.
8-degree pitch.
8 degrees is a low slope and 70mm is thin in the context of roof trusses. What snow zone do you live in?
I have never seen roof trusses under 45x120 and then with reinforcement (w or framework) if you are going to build a gable roof, but on the other hand, it's only a 2m span... But are you perhaps looking for a single beam over like a monopitch roof (truss in one section) rather than a gable roof?
In Snow Zone 1, it should, according to the guide, work with 45x120 C24. If you place it on the depth (1.3m) you might manage with 45x95 even...in the same way if you place them closer than cc 120

In Snow Zone 1, it should then, according to the guide, work with 45x120 C24. If you place it at depth (1.3m) you might manage with 45x95 even...in the same way, if you set them closer than cc 120

It really is roof trusses within “ ” … It's going to be a shed like this, so it's quite simple. Even 45x70 is actually too tall, but it's the lowest I'm considering going. I think it should hold up, but we'll see.

Yes, that's what I thought, it might not be a truss as much as a "beam that holds the roof" (called on träguiden "Roof beams in a compartment")
2m is not completely unproblematic for a 45x70 though, with an 8-degree slope and a meter of snow on it, it can become quite a bit of weight, I would probably go up to 45x95... but then again: If you set like cc 60, you might manage. And it's not a disaster if it breaks either, you can just rebuild it next summer

Exactly, and I can place them at cc 30 if needed too. And very, very rarely does it get a meter of snow in Uppland. And if it does, I can redo the roof as mentioned.
When you sit inside and start feeling "oh, there's a lot of heavy snow on the roof now," you go out and sweep some of it down... I see dimensioning of the roof for that type of building as a non-issue...
Or buy glulam 56x225 and lay it on the slab c-c 600.
You get a thinner roof (which you want) and with a span of only 1.3m, I would sleep well even if a lot of snow came.
"The slope on the roof is only 140 mm.
buy 45x195 or 45x220 and cut a wedge on both sides.
Making a classic W-truss would be ridiculous.
protte
45x220 feels rather overkill. Moreover, the ceiling height inside the small shed would be reduced significantly unfortunately. It will have to be 45x70 and we'll see how it holds. My guess is that it will make it, and if it doesn't, I'll redo it after the winter.

That's how I think too. I have a "kit shed" from Bauhaus measuring 1.4x2.8m with a pent roof where the tongue and groove boards only rest on the outer walls and two 28x120 boards screwed together in the middle in the direction of the "long side."
Shoveled off the snow when it was about 30cm on the roof….
I usually over-dimension but now it's really the other way around.
This is how it looks. The reason I don't want to build with thicker dimensions is to get as much height as possible inside the small shed while not exceeding 120 cm in external dimensions. Partially, the "shed" is buried and will stand under the decking.
It will contain a sand filter and a pool pump.
I will use joists and reinforce, but right now I'm most concerned about the opening which is 80 cm wide. There, I see the greatest risk for sagging.
What do you think about the load-bearing capacity? We will remove snow regardless of the dimension of the timber, but is it obviously too weak for such a small shed?

I can't imagine there will be any problems.
