Older metal roofing in Melbourne is particularly susceptible to roof rust. And although the rusty corrugated iron fits well with the ‘warehouse’ style, which is massively popular at the moment, roof rust can create a huge amount of damage to your home.
Any home which is over a certain age and has a corrugated iron roof is probably already showing signs of roof rust and corrosion.
What causes rust?
The outside layers of both iron and steel breakdown and become flaky when they come into contact with water and oxygen. Unlike other metals, the longer iron and steel are left exposed outdoors, the more it breaks down. If metal roofing isn’t coated for protection, it will eventually corrode until there is nothing left. Obviously this isn’t good for either your home or its roof.
Because rainfall is quite heavy in most areas of Melbourne, roof rust can be a massive problem, especially in the bayside suburbs as salt mixes with the oxygen and rain to accelerate rusting even more.
How much damage can roof rust cause?
If left long enough, rust will eat through the majority of an iron roof, leaving holes big enough to allow rain seepage into not only the roofing cavity, but also the walls and stumps of your home. The integrity of your whole house could be compromised or irreparably water damaged.
What is Galvanised iron?
Galvanised iron and steel have been coated with zinc to protect them from rusting.
Does Galvanised Iron and Steel Rust?
Yes, although galvanising iron and steel does protect them, over time even they will rust.
- don’t scrub with a wire brush or harsh cleaners, because you could scratch the protective layer already on the iron or steel.
- you could try a rust inhibiting primer, however these can be extremely dangerous to use so you need to be ultra-careful
- in most of Melbourne’s older suburbs there are still houses with their original iron roofing; it is likely these homes could be extensively damaged by roof rust. If your home is one of these, you urgently need to call in professional roof restorers.
