They could be glued and clamped together, I suppose, but I gave up on castellations after a while and they're on the list for disposal.
The Beehive Bits castellations ARE too flimsy for my brood boxes but in supers I find them ok as I only remove the frames a couple of times a year
 
Good quality roofing felt offcuts worked ok for me.

This is what I have been churning out for the last few weeks. Untreated pallets, ply off cuts and roofing felt. ALL free.
 
Exactly, and it looks like c**p in the end! 😀

Would agree one needs the proper equipment and expertise to produce a quality product.... my upcycled caravan sheet aluminum roofs are a work of art, and are a matter of hive roof envy when lesser beekeepering DIYers see them !!!

I would love a sheet folding machine but that would mean another shed and SWMBO is complaining about the lack of garden at the moment! 😀

Alli is easy to bend if annealed... made my bender using some nice straight bits of hardwood... don't forget to allow for the radius!!
Last ali caravan deconstruction had sheets still with the blue protective plastic on the inside...
nice new and shiney !!
( and I sold the chassis with wheels for a few very nice bucks)

I've used zinc roofing sheets for my hives, and they've held up well in all weather.
 
They're lightweight, don’t rust, and are easy to cut to size. Ventilation is something to consider, though—without proper airflow, condensation can build up underneath.
all my roofs are zinc sheets over wood, never had a problem with condensation as they are all insulated and there are no vents in the roof and gaping holes in the crown boards - the worse you can do is faff around with 'Ventilation' and allow a roaring gale through the hive.
 
I don’t bother with the wood(OSB) any more. My latest roofs are 200mm cedar edges glued to 50mm PIR with a zinc roof nailed to the cedar edges. They are lightweight a cheap!

and more than adequate

Roughly how much do they cost you to build? Any photos. I like the sound of it.

Where do you buy the zinc from?
 
Do you actually need the galvanised roof on the pir?
Maybe not but you would have to make sure that there was no way water could get through the junction between the ceder sides and the PIR. The roofs would be very delicate and I would doubt whether they would last for long without the galvanised steel skin.
 
I picked up a load of the galvanised roofs in a sale a few years ago for about £10 each and have been gradually working my way through them making roofs with scavenged wood and kingspan insulation blocks. No ventilation.
