Rust Stains On Slate Roofs

Poor quality slate roofing with faulty installation rusting after only 4 years!We’ve all seen rust stains on slate roofs here in Melbourne. What’s worse is that it happens surprisingly quickly even on new slate roofs.

What can you do about it?

Unfortunately, nothing. The problem is unrepairable. The only solution is to replace slate tiles that have rust stains.

There is one good thing to say about rust stains. They at least alert you to a problem because those stains will eventually become leaks so you know the roof needs attention. Not all slate roofing problems are so easy to see.

When you need a new slate roof or new slate tiles on an existing roof, there is only one effective strategy to avoiding rust stains…prevention. Rust stains are caused by faulty slate roofing installation. It is imperative that your slate roofer be experienced and use quality slate tiles. You’ll want to screen your slate roofing contractor very carefully.
