Ok - you may not want this as this will require a stronger roof structure, but man made slates are lighter and equaly durable.
Other options are corrugated plastic / bitument roofing sheets - doesnt look bad and again cant be pecked up easily - just remember to use an edging strip to stop insects and the wind getting in under it.
Hope this helps

Corrugated metal for shed roofs by: John - Admin
The other material to consider is the corrugated metal sheets that are used on farm and industrial buildings. As well as the sheeting you will require a ridge piece and trimming pieces for the edge and sides. This can be fitted over a standard shed roof that has been constructed with ply, boards or OSB.
These materials are not commonly available at the big diy stores but look for a local cladding contractor and they may be able to help. The economy of this solution will be how well you establish a rapport with your supplier as the amounts that you are after will amount to offcuts for the type of building that they are commonly involved with.

condensation by: Anonymous
I would also recommend box profile in sheets for your roof with an addition of a roof underlay. This will stop you having any problems with condensation.
