Use Quality Metal Roofing

When installing a metal roof, whether you’re doing it yourself or hiring a roofing contractor, it pays to make sure the quality of the metal roofing you purchase is high. To best resist the persistent threat of rust, your roofing should be made of zinc-rich base metal. Zinc helps protect the integrity of your roof when it comes to rust, particularly around cut edges where there may not be any additional protective coating. Also, make sure that you only purchase metal roofing that feature a finish or coating that is rich in zinc as well. That will give you the best chance of avoiding rust for years after your roof has been installed.

Perform Proper Installation

Though installing a metal roof may be easier than putting down a traditional shingle roof, it’s not something that should be taken lightly due to its importance when it comes to rust resistance. Sloppy installation can set the stage for future rust issues if the edges aren’t cleanly cut. Also, there is likely to be some scratching of the roof surface during installation. A professional installer will take extra care to touch up those scratches after installation to prevent an access point for rust to penetrate your metal roof’s armor-like coating.

Remove Debris Often

Any roofing surface that is exposed to puddling is at greater likelihood for failure, so the pitch and surface of a roof are designed to get water off the roof as quickly as possible.

However, when debris such as leaves, limbs, and needles accumulate on the roof, it can cause problems for even a usually resilient metal roof. That organic material provides the perfect place for moisture to become trapped. Simply stated, moisture leads to rust. Therefore, to prevent rusting, it’s important that you promptly remove anything that can hold water against your metal roof surface.

Treat Metal Roof Rust Carefully

Even if you do begin to see rust on your metal roof, all is not lost. You can gently treat many types of metal roof rust with a household chemical that is relatively harmless yet still effective. Rust can be removed from most metals with a mild application of white vinegar and gentle brushing. The acid in the vinegar reacts with the rust and eats it away. Preventing it from spreading and compromising your roof, just be sure to wash the vinegar off after a few minutes. Then, retreat the area with touch-up paint or coating to prevent the rust from coming back.
