Got a half-finished attefallshus with the purchase when we bought a villa. Interior, surfaces, and roof insulation remain on the attefallshus. I'm quite convinced that the roof trusses supporting the roof are severely under-dimensioned. The roof is approximately 4.4m wide and 4.2m deep. There are a total of 5 roof trusses with a board standing on edge. The board is only 4.5 cm wide and 8 cm high. Now the roof holds, but then there will be a lot of insulation, a ceiling, and drywall on it. Then possibly a lot of snow on top. This is how it looks currently if you stand inside and look up. What do you think? How large should the roof trusses be to be safe, and how can this be corrected at this stage?
I want to believe that the trusses are covered with paneling on the underside and now just nailed lining to be able to insulate the roof. If what we see are the trusses, you should reinforce before the snow arrives.
If you want some useful advice, more information is needed. Measurements, roof pitch, snow zone. What does the entire roof structure look like? The pine boards visible in the ceiling, they are hardly the top layer, right?

No, unfortunately, it is the rafters we see in the picture

The roof slopes about 30 degrees. Snow load zone is 1.5-2.0 (Härryda). On top of the pine boards, there's a felt roof and nothing else, so it is pretty much the top layer.
When I look at kits, I see that ridge beams for this type of sloped roof are usually 45*220 with C24. However, I have no idea about the quality of the wood in the house.
By guessing the dimensions, I conclude that nothing other than 45x220 C 24 will suffice. However, it may take many years before a situation with maximum snow load occurs. Accurate measurements of span, etc., are a prerequisite for a correct calculation. Quite a lot of snow can fall in the Härryda area!

How do you replace the rafters without tearing down the roof? Can you lift it with jacks or something?
When did you buy the house? It's amazing that it can be built like that, it's dangerous! Make sure snow doesn't accumulate on the roof this winter if you don't reinforce it before then. As mentioned, if the roof looks like this, how does the rest look? Does this fall under hidden defects? The new reglarna could be attached to the side of the hammarbandet with joist hangers, for example.

Bought it this spring. The Attefall house was built over the last two years by a lone DIY enthusiast. Unfortunately, I'm coming from an apartment and had no knowledge about houses when we bought, and unfortunately, we didn't inspect the Attefall house.
