"Change it to a conventional warm roof.
This will increase the thermal U value and offer the best long term solution. The roof membrane can be numerous options, with additional metal simulation trims
to aesthetically improve the installation.
Additional sub structure supports will be required with internal ceiling or cladding finish."

"Quick answer would be to replace the roof with a light weight pre fabricated, made to measure, insulated roof with a light weight slate finish."
