R C Roof
The R C Roof appears to be intact but some inside spots have rust. 1) Would be interested to know the lifespan of this roofing material? Some further info is: supports facebrick building, situated in Gauteng, South Africa.
2) Would be interested to know the history of this roofing practice.
The inside has a corrugated surface seemingly from the metal that would have been used in the mould? I can see metal pieces/nails sticking out on the side.
Glad you found an answer! At least, I think you found an answer...Let us know if you didn't find an answer!
