Replacing a sectional garage roof

[amfisted]

Evening all

I've had a couple of quotes for replacement of the pitched asbestos roof of my sectional garage. Not unreasonable quotes, but I'm thinking about a DIY option. The current roof doesn't leak at all, so its not a repair, but an upgrade to a non-asbestos roof that I'm thinking of.

I don't know the technical terms for the internal components of the roof, but the asbestos sheets are laid on and fixed to a total of 12 L-shaped metal supports that span between the 2 concrete cross members inside the garage and the garage ends. I'm thinking of replacing with corrugated metal, but I don't know how they'd be supported and I'd also need anti condensation measures on the underside of the sheets.

I would of course have the asbestos sheets removed and disposed of by a qualified contractor.

Any advice/ information about laying a pitched corrugated metal garage roof gratefully received, but the main question is whether I'd save any money by replacing the roof myself when the quotes I've had include disposal of the asbestos sheets.

TIA

My neighbour had an asbestos garage roof removed around 2021 for £550. Took 2 hours.
Probably cost more now.
Then you have to put on a new roof.
OSB board and felt maybe.
Look up the many posts on this forum regarding OSB garage roof...

Or you could go down the metal sheets but that can get condensation and be noisy when it rains

Many thanks. I was quoted 2.5k by a garage roof specialist last year for stripping and disposing of the asbestos, then re-covering with metal and a condensation barrier.
I guess OSB and felt is an option, but maybe I should just save up.
