We've got a flat roof on top of our apartment block that is approx 30 years old, and are looking for general advice on maintaining it, as we are concerned about the discoloration.
Some basic questions we have are:
- What is the roofing material? Zinc? Tin? Lead? Something else?
- Is the discolouration (brown rust colour) serious damage, or just aesthetic, or somewhere in-between?
- What steps should we take to extend its life?

Thanks for any input.
