Assuming you don't have a gantry above it, then I'd go for jacking from
beneath. That weight is more than most roof timbers would appreciate.

I'd probably use a load of small jackings and repeated stacking with
wooden packer blocks. OTOH I have plenty of timber to hand (there are
always pallets though). How many trolley jacks can you borrow ?

It weighs less than I do, and I was up in my loft at the weekend ...

That's a loft in a house, I'm assuming this is a shed. I wouldn't walk
on my shed roof...

Good point. Although I'd walk on my shed roof, but then my shed isn't
a GBP29.95 B&Q special.

Ah... but were you jacking from beneath?
