Langstroth Beehive Galvanised Assembled Roof 4"(100mm) Deep - European Style by Thomas Apiculture

£20 for a decent roof, can't say fairer than that

Ordered a couple of these to get ready for more colonies later in the year. They have no wooden interior and are just the galv sheet. Nice and deep, 0.6mm thick galv sheet and the whole lid comes in at 2kgs. I added a 25mm slab of insulation and a sheet of OSB to stop the bees getting at it. That, combined with the 50mm already in my DIY feeders means they'll be toasty all winter and not boiling over in the summer. No sharp edges and nicely folded corners unlike some found elsewhere.
