I think it tends to happen most in the heat, although I can not be sure, however the loft extension on my house seems to do some almighty cracking and popping through the night.
Mrs SR and I sleep in the loft, consisting of a large, north-facing dormer, an en-suite bathroom, and a south-facing velux skylight, and which we had built by a reputable firm about eight years ago. As far as I can tell, there are no structural issues with it, and we have neither noticed nor felt any imperfections.
But, jeez, does it ever crack!
I have heard the cracking for a few years, but am really noticing it right now, as I have not been sleeping well. What are the possible causes? And is it normal?
It’s a crack house.
Sometimes the PVC soffits (or perhaps the gutters) make cracking noises on our house, I imagine it's noisier in the loft. Garage roof does it too (insulated metal sandwich roof).
Loudest crack though...it's got to be the Bosch fridge freezer. It sends the cats about 3 foot in the air if they are chilling 🙂
Differential thermal expansion and contraction of materials innit.
Fibreglass flat roof? Inlaws had to get their's redone as this was causing lots of noise
My dusty old Terrace house does it too. Sometimes makes me jump if I'm nodding off at night.
What pp says, 100%.
Edit: not the crack house bit, the thermal bit...

It was built on top of an ancient Indian burial ground, and the ancient ones aren't happy with your lifestyle.
Almost certainly a sink hole under your property. I can sense it.
It's creaking under the sheer weight of bairns.
Perhaps there's a knight on the tiles?

Is this anything to worry about long term? And why have I never noticed it in any other house before?
We had similar on a large extension I added to our bungalow, ground floor area was 920sqft and loft trusses were 26ft wide. In hot weather I believe the trusses would expand and move very slightly on the wall plates causing an almighty crack, annoying, but not life threatening.
We moved house two years ago, but not because of the crack.

I remember watching a documentary about that, upshot was don't spend too long watching static on your TV, it can all go horribly wrong.

I know it's warm, but chilling cats in the freezer....
At college our somewhat eccentric physics tutor spent half a lecture telling us about his daughter's house and how a crack had developed over the summer. For the rest of the term, I swear not one lecture went by without someone asking how her crack was shaping up. To his eternal credit, he managed to avoid even the raise of an eyebrow.
It might not be your house. Our fridge pops and crack sometimes quite loudly, exaggerated at night time of course.
I'm sure he knows the difference between a fridge and a house.
In our house it's the plastic guttering, as it shrinks back from the heat of the day the clips grip it tight until the tension is too much. It's not 'that' loud but you might have something similar, but bigger.
(or an hot angry monster in your roof cracking knuckles, getting ready 🤷🏻♂️)
The fridge is because they no longer use the same cfc gas. Mine makes a hell of a noise.
My ex landlords handyman secured some older pipes with expanding foam. That made some really loud cracking noises which quietened down over time but didn't stop.
I assume as all new foam type insulation is cfc free it has the same problems associated with the fridge.
In the dark you can sometimes hear your own heartbeat
Or the heart of the one next to you
And the house settles down after holding itself up all day
Shoulders slump, gives a big sigh
You hear no ones footfall in the hall
That drip in the kitchen sink keeps marking time
June bug on the window screen can't get in but keeps on trying
One way or another we're all in the dark
