No accessible rafter, convenient or otherwise. Clearspan roof 5’5 metres high. Not gonna buy a block & tackle just for this one off job. Might be able to use an old ‘comealong’ I’ve got though I think TD’s suggestion of an A frame would be required if doing it myself........ unless....... the old shed has accessible rafters but very limited space around the vehicle. Will have to suss out if it’s do-able there.
