ᐅ Gap between common rafters and principal rafters

Hello,

before I possibly contact the house building company, I would like to get your independent advice.

So, in 2017 – four years ago – I built a bungalow with a hipped roof. During the final inspection in the presence of a certified expert (TÜV), no visible defects were found. Now, after four years, I have noticed a clear gap between the rafters and collar beams, which apparently developed over time (otherwise it likely would have been noticed during the final inspection).

My question is: is this normal, or does it require action? Does it have to be fixed by a roofer? And if it needs to be fixed, could this possibly be a defect for which the building company is responsible (to my knowledge, the warranty period is five years from the final inspection)?

I would appreciate any assessment.

Regards,

Just out of curiosity: is something like that really nailed? Where I am, they always came with those intimidating, arm-length large-head screws.

That’s not going to cause your roof to collapse right now, but I would definitely follow up on that. I don’t see 2cm (roughly 0.8 inches) as an acceptable tolerance.

What surprises me even more is the blunt impact.

What type of roof is this if the rafters form an angle with the ridge beam?

Also, what type of roof is it based on the angle of the rafters to the ridge beam?

He actually writes: hipped roof. The first photo basically looks like a herringbone pattern slanting downwards. At the very bottom, you can see the corner of the house where it rests.
