Stone slabs on my shed roof? Are the worth anything?

Stone? Or asbestos?

They are stone sheds with huge stone slab roofs

I'm pretty sure 7cm thick sheets of roof asbestos was never a thing. 🤣 I'd like to see some photos of these awesome sheds. Why do you want rid?

You're going to need a hiab truck to lift those too! 

They are old stone shed (nothing special)

One's got a loo in it. Haha

If they aren't worth anything I was thinking of somehow smashing them up

I'm not sure how to upload photos anymore

They'll definitely be worth something. It would be a shame to smash them up. Hard part will finding a buyer who can actually take them away. Certainly worth trying..

If they're decent stone they'll be worth something for sure. If they're crap stone, not so much. You could try selling them to a reclamation yard, although I imagine they won't want to pay you anything if they've got to collect them. If you really need to 'smash' them up, maybe try and cut them into manageable slabs and sell them that way.

Reclamation yard certainly sounds like the way to go, to me. These things aren't going to be ten a penny, and they'll be worth making available for someone who's doing a restoration of a roof on an old building. Even if you get nowt for them, it's the 'right thing' to do.

Are you getting rid of the sheds altogether, or spending money on replacing (presumably) proper period roofing slabs with something else?

They are very definitely worth something. Whereabouts are you? Around me (BBNP) there's always a demand for stuff like this for renovations etc.

Please don't break them; make garden furniture or something. Just don't smash them.

Assuming 2.5 g/cm3 ( and i would) they are going to be quite heavy, so careful...

If you're anywhere near Gloucestershire I'll come and take them off your hands! 

About 340 kg each. How many do you have?

Also interested. Where are you?

Not saying they are worth this much but based on your measurements you have a bit over 8 square meters of coverage. British flagstones sell for around £200 a square metre 

Things like Cotswold Stone flagstones, roof tiles, etc are very valuable - for anyone restoring or converting a former farm building or cottage, it’s very difficult to source materials that are appropriate to the location, and approved by the local planning department. 
For example, a close friend of mine has an 18c farmhouse near Castle Combe, and she was converting former outbuildings to accommodation for self-catering guests. She knew exactly where the original quarry was that the stone came from, but she wasn’t allowed to take stone from it for ‘environmental reasons’, but the stone had to match what the buildings were constructed from! It caused her no end of grief trying to find stone that satisfied the planners! 
This is the house as you see it from the front:

and this is what she was trying to build, and finally succeeded - there’s a not insignificant amount of stone required…

Thanks all.

Shame I can't upload a photo.

I'm near Bolton. 

I think they are flagstones. (York flagstone)?

How would someone get those things down from height? Like you say, they will weigh a ton!

Well, 1/3 of a tonne at any rate, if tthew's calcs are anywhere near correct.

The answer is probably "telehandler and some hefty straps"

Closer to 1/2 tonne each, 2.2t/M3

Seems a strange roof but maybe an old butchers shed to keep the carcass cold 

Actually I maybe misunderstood the size of the slabs. I now think that's the total area of the roof not the size of each slab. They'll still be too heavy to lift at 7cm thick though! 

Loads of old outhouses had huge yorkshire stone slabs as the roof where we lived in West Yorkshire. Ours were c5ft x 2ft x 7 or 8cm thick...and there were 3 overlapping on each of the two sheds. Been there 130+ years...likely still be there in another 130yrs. If you can get them down (safely) in one piece and advertised, they'll sell well

I'm imagining these are typical single story, single pitch old outside bog type of buildings like we have around here. I've taken the roof off one of ours although not quite as hefty slabs.

I'd be propping a couple of hefty timbers against the low side at a 45degree angle and sliding them down. A couple of hefty straps like ratchet straps etc and a couple of strong blokes at the other side could manage a controled slide I'm sure.

Probably straps and a crane.

Wierdly, a friend in Bolton just posted this picture on Facebook....
