Or box profile plastic coated steel. Much lighter to handle and

They will cut it to size for you.
Lasts15-20yrs depending on what grade you get.

Modern materials aren't durable, are they? Onduline is about 15 years if
looked after (kept cleanish and moss etc. removed - not much else that one
can do), steel only a bit longer.
The roof on my shed is asbestos cement, has had a lot of moss, is only about
7 - 8 deg. slope and is ~60 yo. Yes, it has a few cracks but it doesn't
leak.
Trouble is, although I'd like to replace it before it cracks in a critical
place, there seems to be nothing that would be easy to use. There is only 1
support in 3m at a low angle and anything new would require at least 3 or a
full deck - and even a deck needs more support.
I'll leave it until a tuit lands in the garden.
