Rusting On Metal Roofing And How To Treat Them

Rusting On Metal Roofing And How To Treat Them

One of the common problems that you will encounter if you have metal roofs is rusting. The rusts are the brownish-orange stains you will often see building up on the edges of your roof or around the metal screws that are securing your roofing in place. Rusts are signs of corrosion that can compromise the quality and durability of your metal roofing and that is why you should be aware of it.

There are a number of reasons why rusts form on your metal roofs but there are also ways to prevent and treat it.

Why Do Rusts Form On Metal Roofing?

Our roofs are exposed to many different elements that eventually weather them down such as intense heat from the sun, strong winds, and rainwater. When it comes to rust, water especially plays a big role in causing this to happen because water contains moisture and oxygen. These elements, when mixed together, create a chemical reaction and forms an iron oxide which is basically rust.


How Do We Deal With Rusting?

When you see that rusts have already formed on your metal roofing, do not panic yet as there are ways to treat it and prevent it from completely taking over. We listed them down for you:

  1. Scrubbing With Soap And Warm Water - If the rusting is still new, it is still treatable with some DIY Newly formed rusting has not yet clung and eaten the metal yet so scrubbing it vigorously with a wire brush, soap, and warm water can do the trick.


  1. Wipe With White Vinegar – White vinegar is another DIY method that you can try to remove rust from your metal roofing. Simply soak the rusting part of your roof with white vinegar for hours and then wipe it away after.


  1. Roof Restoration – In worst cases, most of the parts of your metal roofing have already been eaten away by rust. These can no longer be treated by simple scrubbing and DIY solutions. In the event that your metal roof is already compromised because of the rust that has festered, the best thing to do is to call for roof restoration services.


How Do We Prevent Rusting?

  1. Replace Old Screws And Fasteners – Old screws and metal roof fasteners often hide early signs of rusting underneath and even if they started out as a tiny spot, letting them fester will only allow them to grow and eat away on the metal. That is why you should replace old screws and fasteners to discourage rust from growing.


  1. Apply Roof Coating – Roof maintenance is one sure way to prevent rusting and part of this routine is the application of roof coating, which is corrosion-resistant. A roof coating can last 10 up to 20 years, keeping your roof rust-resistant for a long period of time before you need to apply a protective layer again. Roof coating application can be tedious and requires attention to detail to make sure that all parts of the roof are covered. You can make sure that not an inch of your roofing is missed by keeping in touch with professionals who do roof maintenance services.
