Shed roof - maybe asbestos

A quick google search returns “only a licensed professional” coupled with a lab test is the key way to go .

No asbestos definitely not allowed in general waste skip- but depending on roof structure, it may be a straightforward disposal - ie if it’s simply secured by some nuts and bolts which my family home shed was -but it will take a company licenced to deal with that regardless - but if it’s an unscrew and lift job, obviously much more straightforward as fibres less likely to come apart in volume

I'd be fairly confident that is asbestos. Best advice I can give this weather is to keep it wet so any dust doesn't blow around. Might be worth checking on google but I believe you can spay it with PVA glue to help prevent the dust.

That is very cheap or its a very very small roof! I suspect whoever has quoted that will take no notice of the asbestos or the regulations for safe handling and disposal.

That's what I was thinking alright.

As a comparison, I was quoted (by a legitimate asbestos removal company) 3,000 euro to remove and dispose of an asbestos stippled ceiling in a small box room.

More than likely this is what's used, hammer in and screw out, cutting them with a small bolt cutter from underneath is probably the best way to remove the sheet's

Sounds very cheap . Have they a waste collection permit for starters or are they a few lads in a white van?

If I were you I'd contact the National Waste Collection Permit Office in Offaly. They'll be able to tell you straight away if your lads are authorised.

In fact if you Google the NWCPO they'll probably have a list of registered removal companies. It's not cheap material however to dispose of.

A PVA mix (1 part PVA to 5 parts water) sprayed on with a garden sprayer at low pressure would be easier you don't need to get quite so close to the asbestos and can spray into the gaps above the beams where the nails go through.

I took down an old asbestos roof on a shed in the back garden about 20 years ago. They were held doen with thoae spiral nails. IIRC I clamped a vise grips onto each nail head and rotated. A lot of the nails broke.

I had enough space to stack the sheets against a back wall, where they remain, covered in ivy.

By the way it IS acceptable to store the sheeting on site if you have the space - I checked at the time.

Total cost: a Tyvek suit and a P3 mask.

Ideally you need to double bag and separately seal each layer. Don't forget that plastic will degrade over time particularly outside.
